With the ability to test materials before they are extruded, Guill customers receive testing coupled with industry experience and shorter lead times
Guill Tool, manufacturers of extrusion tooling for the global market, has opened an in-house rheology laboratory, making it the only extrusion tooling manufacturer in the industry with such a capability. Seeking to obtain better results and minimize the time it takes between testing and production, Guill built its own rheology lab in their facility in West Warwick, Rhode Island, USA. The lab features several key machines that ensure optimum results, when testing materials, especially new compounds to be extruded. The testing equipment includes a Hybrid Rotational Rheometer, a Differential Scanning Calorimeter, and a Thermal Conductivity Meter.
Third-party testing facilities are typically not experienced in extrusion processes. Guill, however, can not only gather data the same way third-party testers can, but can also interpret that data as it applies specifically to extrusion. Likewise, third-parties simply supply data, not recommendations. Guill is now equipped to both test its customer’s materials and work with them to create extrusion tooling that will give them a competitive edge. Accurate simulation and interpretation by extrusion experts greatly reduces the number of physical reworks needed, as the tooling has a greater chance of producing a good product at the outset. In-house testing also speeds up the turnaround on test results, reducing delays during the tool design process and offering better control over the processes and test parameters.
The new Guill rheology lab processes standard materials, custom formulae and it is equipped to mix materials. These materials include plastics, thermoplastic elastomers, all types of rubber and silicone. Information from the lab is transmitted directly to the Guill engineering department via computer link for review by the design team.
The lab will be offered for use by extruders and chemical formulators, among others in the industry. Please contact Guill for full details.

The demands for prototype, tool and mold making are increasing. Only those who can supply high quality output, quickly and flexibly, can succeed against the powerful competition worldwide. Zimmermann is responding to this trend with the new FZU. This 5-axis gantry milling machine is not only extremely compact but, thanks to its thermo-symmetrical design and accuracy, it also provides the ideal entry point to the Zimmermann machine line with maximum productivity. Plastics, casting resins such as Ureol and aluminum are particularly suitable for machining. “This development will enable us to close the gap in the lower weight class,” states Frieder Gänzle, General Manager and Partner at Zimmermann in Germany.
“The basic expectations, which prototype, tool and mold makers need to meet today, have not necessarily changed over the years, they have simply grown,” sums up Frieder Gänzle. Customers in the automobile industry, he notes, especially expect components with almost perfect surface finishes and ever higher accuracies. Manufacturers introduce new models or variants to the market at ever shorter intervals. Whereas prototype, tool and mold makers could previously plan in the longer term, they must respond today to inquiries considerably faster.
“We cultivate a very special relationship with prototype, tool and mold makers,” says Gänzle. “Together, we have evolved consistently in recent years. We are very appreciative of our strong business in this sector.” Zimmermann is continuously exchanging technology information with its user base. In discussions, it has become clear that this sector requires powerful, compact machines with maximum productivity and open time. And, importantly, Zimmermann must offer an attractive price/performance ratio, while meeting all these requirements. “We have evolved even further towards heavy-duty cutting, over the years,” reports Gänzle. “As a result, even the smallest machine in our portfolio, the FZ33 compact, has become more popular. We have continuously pushed it upwards from a technological point of view.” Its focus is on aluminum cutting, but steel can also be machined. This enables Zimmermann to offer customers a very efficient, flexible and space-saving machine, while the corresponding design improvements have also had an effect on the price. “The requirement we were presented was for an entry-level model which rounds off our program at the lower price point,” explains Gänzle. The result is the FZU, a 5-axis gantry milling machine which is optimized for weight and stability.
Pre-assembled machine concept
In contrast to the established FZ33 and other machines that Zimmermann offers today, the company is taking a different path with the FZU. “We can narrow down the special features of this gantry machine to three main characteristics,” describes Gänzle. The first point: “We are following the trend towards modern manufacturing machines and designing them as space-saving, pre-assembled units.” This means Zimmermann assembles the machines in-house and can then transport them to the customer by truck or ship without having to dismantle them. Onsite, they are ready for use in a very short commissioning time; erection and start-up require minimum effort. For the customer, this means quickly available machines which can be installed without constructing foundations. “In the design, we have kept to the usual transport sizes. At the same time, the new FZU achieves a remarkable working range for its size,” explains Gänzle.
It is important to match the machine to the required dynamics. Adverse environmental conditions and long machine running times necessarily give rise to thermal expansion effects. In spite of the customers’ increased accuracy requirements, the machine must always achieve outstanding surface finishes. The Zimmermann engineers have therefore designed the FZU gantry machine to be thermo-symmetrical. This means that the milling spindle, guides and other accuracy-determining components are arranged so that their heating is either compensated or they can expand in uncritical directions. “This is the second important characteristic,” emphasizes Gänzle. The base frame consists of a steel welded construction which forms a continuous U-shape. The machine gantry’s centrally guided Z-slide has an octagonal section – and not a rectangular one like comparable machines – which makes it particularly stable. Thanks to its design, it therefore has impressive rigidity for its size. “With a weight of approximately 35 tons, a length of 3,500mm, width of 7,500mm and a height of just under 5,000 mm, we have been able to build a light and compact machine,” says Gänzle.
In-house head implemented throughout
The third characteristic relates to the new VH10 milling head, which achieves an extremely high power density. “This new development has enabled us to reassess our portfolio,” reports Gänzle. This is because the VH10 head will replace the VH12, which is not a Zimmermann product. Alongside the VH20, VH30 and VH60, the VH10 is now the smallest head in the range. Users will also benefit from the fact that Zimmermann has suitable spare heads in stock and can supply them on request in the event of stoppages, for example, due to a crash. “We strive to respond quickly and provide the customer with optimum support,” emphasizes Gänzle.
Thanks to its slender design, the VH10 spindle head has only minimal interference contours. Compared to the VH12, it achieves almost double the clamping force. This is due to the fact that Zimmermann fits two side cheeks instead of one onto the unit. The VH10 is therefore considerably more stable in operation. In order to minimize throughput times, a powerful 34 kW spindle with a maximum speed of 24,000 rpm is used in the milling head as standard. “The FZU is therefore ideally suitable for the materials typically found in this business sector, such as Ureol, clay and aluminum. In the future, we will also use the new milling head in larger machines on which processers can produce one-to-one models – for example, on our FZ37,” says Gänzle.
Standardized and yet individual
In order to provide a high-quality machine at an attractive price, the designers at Zimmermann have turned their attention to remaining competitive with regard to price through increased component standardization, while at the same time addressing individual customer requirements. As with all machines produced, Zimmermann therefore also relies on a modular system with the FZU. Among other things, this approach enables different size variants and power levels to be produced. There are also numerous equipment options which offer the customer maximum flexibility.
Zimmermann is therefore able to provide a very efficient solution with the new FZU. It is often the little things that give rise to success and customer satisfaction. “We place great importance on details – an aspect which cannot always be measured in the numbers,” explains Gänzle, who cites two examples: “For instance, the machining area is fully clad with stainless steel sheets in order to guarantee maximum resistance to abrasion. The FZU is also the first gantry milling machine to be equipped with our innovative, new NXP 24-inch multitouch controller, which is already used on our FZH horizontal machining center.” Another increasingly important topic is ergonomics. The door is divided asymmetrically to enable components to be easily fed to the machine. A small, easy-to-open door leads into the machining area, while the large door is used for loading. Operators therefore have a relatively large field of view, rapid access to the machining area and ample space for loading – ergonomic advantages which are not to be underestimated. Another detail is that a cabinet has been installed directly in front of the FZU. “This was the idea of one of our designers,” says Gänzle. “The tables, which users in the various plants position in front of the machines to place their accessories and service tools, caught his attention. With our solution, everything which is part of day-to-day operations can be safely stowed close at hand within the machine.” Added to this, there are extraction equipment and special chip management systems. “It is often the simple ideas which make the machine operator’s everyday tasks much easier,” sums up Gänzle.
To provide the best possible support to businesses, Zimmermann concentrates on high-quality and reliable service in close proximity to the customer. After all, this is exactly what characterizes a good relationship between supplier and user. “Customers expect high availability over the entire system lifecycle,” says Gänzle. “We provide comprehensive machine care.” This includes a customer hotline, by means of which users can reach a competent contact person, even outside of normal working hours, as well as a remote diagnosis system that allows a rapid response in an emergency. If mechanical components are defective or malfunction, the machine builder usually guarantees immediate shipment from its factory. In addition, the application engineers work together with the customer to optimize each individual combination of heads, spindles, tools and clamping equipment for the machines. Zimmermann therefore not only sells machines, but also complete solutions. Plans are in process for further upgrades to the stocking and service personnel staff in North America, as well. Zimmermann recently opened a new facility in Wixom, Michigan, near Detroit.
Goal: To be technologically out in front
“We don’t want to be chasing trends; instead, we want to help shape the market,” says Gänzle. “Basically, we therefore aspire not to do the same things as our competitors.” To be technologically out in front, the machine builder never stands still with regards to machine development. The FZU is therefore being continuously optimized – without at the same time losing sight of the price/performance ratio. There appears to be substantial market interest in these machines, according to company research. The initial discussions with users were highly promising. “We are confident of meeting our customers’ requirements with this new development, both in Germany and internationally,” says Gänzle. The statement that the concept of the FZU could be transferred to the other machines in the program underlines how convinced he is of this new solution. Zimmermann will be presenting the machine to a specialist audience at WESTEC 2017, CMTS 2018 AMB in September, 2018. As further indication of emerging market interest, three users have already decided to purchase this new gantry milling machine.

Increase in plant and office capacity responds to global growth for tube & bar processing machine builder
Global manufacturer of tube and bar processing machinery Rattunde today announces a substantial increase in its plant and office capacity at the company’s global headquarters in Ludwigslust, Germany, near Hamburg. The announcement was made by company president Ulrich Rattunde.
At a company gathering in early July, Mr. Rattunde announced that he had signed an agreement to purchase the entire facility of a neighboring company literally across the street from the existing Rattunde facility in Ludwigslust, namely Alstom, the multi-national rail transport and power generation firm. This acquisition was completed on July 25, 2017.
The new 175,000 sq. ft. manufacturing facility for Rattunde is more than double the current size, thus permitting substantial expansion in the production of machines for this builder of tube & bar processing equipment. Rattunde markets globally to a variety of industrial OEM’s and contract manufacturers. In tandem with its U.S. facility in the Grand Rapids, Michigan area, the company is now better positioned to serve its established install bases in Europe and North America, with the added capacity enabling continued growth and expansion into the emerging markets of Asia and South America.
In tandem with the larger manufacturing facility, Rattunde will now also enjoy 18% more office space for its design, engineering, sales and service personnel in Germany.
Rattunde Corporation president (North America) Rick Stadler observes, “Everyone in the company is excited by the potential of the new headquarters. We will not only have greater capacity to respond to current customer delivery needs, but this development will enhance our competitive status around the world. It’s a very exciting time for Rattunde.”
Stadler also mentioned the recently opened Rattunde facility in Mexico, where the company has substantial and expanding business engagements.
Universities and technical schools trying to keep up with advances in digital manufacturing often find themselves behind industry. However, I was privileged to visit one university, the University South Carolina, which will now be an important exception. Founded in 1801, USC is one of the oldest universities in the US with a history of creating the most innovative learning programs dating back to its first curriculum obtained from Oxford University. Today, USC is establishing a one of a kind Digital Factory Lab that combines technology and coolness to inspire and educate its students.
This past week, Siemens announced a partnership to help the University of South Carolina to accomplish this goal with an in-kind grant of hardware and software. “Welcome to Brain Power USA! Siemens is investing $628 million in high tech training for 4th industrial revolution jobs in South Carolina,” said Henry McMaster, South Carolina Governor. By providing students with this hands-on experience on software and hardware across USC’s engineering curriculum and in research programs, Siemens is helping prepare a highly-skilled STEM workforce for the advanced manufacturing industry, including the aerospace industry, which has experienced an 11.4% employment growth rate in South Carolina since 2010.
Ramy Harik is one of the professors at USC and he told me that these new resources will be put to good use. Already his students have been involved in working with composites, designing new ways of analyzing data for the helicopter AH-64 Apache airframe and developing insights into that aircraft’s mechanical operation for the Army. More innovations are sure to come. For instance, beginning this fall students will also be able to pursue a major in aerospace engineering.
In recent years, the state of South Carolina has become a magnet for sophisticated manufacturing particularly in aerospace, automotive and tire. As a result of working with these companies to deploy high-tech manufacturing and by supporting vocational learning in the state through USC’s College of Engineering and Computing and the McNAIR Center for Aerospace Innovation and Research, USC has grown into a major research university. Specifically, the McNAIR Center is aligned with two dozen educational and government partners, and a group of industry partners that include The Boeing Company, Fokker Aerostructures, KUKA Robotics, Ingersoll Machine Tools, Gulfstream and more.
The recent gift by Siemens to University of South Carolina will contribute to the state’s overall goal to become the smartest manufacturing state in the United States. I know this is not only important to the Governor of South Carolina, but also to the USC President Harris Pastides who said, “We’re proud that our researchers and students at the College of Engineering and Computing, McNAIR Aerospace Center and the entire USC system, will play a role in discovering new manufacturing technologies and will be better prepared to take on the jobs of tomorrow in South Carolina and beyond.”
To date, South Carolina’s business, education and state government partnerships have created jobs for more than 55,000 South Carolinians in the larger aerospace industry. As Raj Batra, President, Siemens Digital Factory Division, U.S., said, “Aerospace companies throughout South Carolina are heavily reliant on automation and digitalization as well as well-trained employees. Our partnership with the University of South Carolina will provide valuable experiential training with both software and hardware, providing the next generation workforce with the skills they need to be successful.”
Far from lagging, educators in South Carolina are working hard to stay out front. While I was at dinner, USC’s Hossein Haj-Hariri, Dean of the College of Engineering and Computing, told me “We are going to work very hard to make this the best investment that Siemens has ever made.” I am proud to be part of a company that will match that enthusiasm and make this a program known for enabling students to be competitive for jobs throughout the world.
Governor Henry McMaster, we are ready to help you build the workforce of tomorrow.

Ideal for aircraft parts including flight controls, fuselage panels, fairings or engine inlets; ROBOTsander sets new standard of excellence for surface treatments
Suhner has released its new ROBOTsander, a highly capable and adaptive surface treatment solution used in the automotive, aerospace, appliance, off-highway and outdoor power equipment market. Operations that benefit from the ROBOTsander are material protection, surface brightening, paint preparations and CFRP activation. Applications include grinding, brightening, polishing, deburring and sanding. The ROBOTsander can safely be used on metal and composite materials alike, using Suhner application-specific abrasives. Its design significantly reduces cycle time and use of abrasive materials. Furthermore, the ROBOTsander solutions meet customer surface treatment needs and requirements in a cost-effective manner with minimum deployment time. The device is ideal for large volume and large area production.
Responding to the digital factory trend in many industries today, each process in itself, as well as complete robot cell functionality, can be analyzed by Suhner engineers and manufacturing specialists. This allows optimization to be performed well in advance of the initial delivery, thus reducing process risks and overall deployment time.
The combined use of Industry 4.0 objectives with the Suhner Digital Factory Monitoring System, allows the customer to monitor-onsite or remotely- the sander’s performance. The ROBOTsander turns any robot into a collaborative robot. Additionally, it provides data recording, process diagnosis and optimization, predictive maintenance and remote product support, as well as spare parts and user time management.

Guill announces the introduction of a new version of its popular 800 series, known as 800 Series Hybrid. In some extrusion applications that utilize crossheads and inlines, layers of the exact same material are applied multiple times, using a single die. This method is used to reduce the propensity for errors caused by gels breaking through a thin wall, weld lines, inconsistent wall thickness, plus material and process variations. Additional errors include difficult-to-process materials and demanding applications where there is zero fault tolerance.
Seeking to design the next generation multi-layer die to overcome these challenges, the engineers at Guill looked for a way to incorporate this technology into an updated version of the 800 Series. This led to the creation of the 800 Series Hybrid. The inherent benefits of the 800 Series are retained, including compact design, low residence time and a common deflector bore that eliminates tolerance stack up. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping, while reducing unnecessary complexity and making the technology more cost-affordable for customers. This was achieved by overlapping layers in each semi-deflector, using a single cone. The highly efficient design of the 800 Series Hybrid reduces cost and size, as opposed to other methods of overlapping layers.
Essential benefits of the 800 Series Hybrid include eliminating weld lines in materials through patented overlapping technology, producing a more consistent finished product; reduced sensitivity to changes in viscosity; reduced sensitivity to changes in line speed; myriad material and multi-layer application possibilities; works in all tubing and jacketing applications with a wide range of materials; low residence time; compact design and a low tolerance stack-up error factor, all resulting in improved concentricity.
The 800 Series Hybrid extrusion tool greatly reduces stagnation, because overlapping layers are more inherently balanced than single layers and also because each semi-deflector is “tuned to flush.” Conventional deflectors must simultaneously achieve a balance between flushing, balancing and eliminating the weld line. There is less difference between the slowest moving material and the fastest moving material in the deflector channels, thus making the viscosity more consistent in the deflector.
