The process-oriented approach of SIGMASOFT® makes it possible to use injection molding simulation of elastomer applications not only for filling or cooling times, but also the non-productive times between each process phase. When the process is simulated considering the influence of operational times occurring between the main process stages, the accuracy of the simulation is dramatically improved.
Temperature distribution in a metallic component overmolded with elastomer. Left: without consideration of the mold opening time; right: considering a mold opening time of 60s.
Schaumburg, IL, September 7, 2012 – Even though it is not necessary to include them to complete an injection molding simulation, the non-productive times have a major influence on the process and on part quality. Process Simulation Software SIGMASOFT®, from SIGMA®, can include non-productive times in the simulation enabling substantial improvement in the accuracy of the results to be achieved.
Taking into consideration the times in which the mold opens and closes, the times in which it is heated up or cleaned, as well as handling times when the inserts are placed simulation makes it possible to accurately analyze the process cycle. The interaction between all mold components has to be considered and cycle times have to be predicted accurately. That way even factors that influence the part quality, such as the curing degree, can be predicted by the simulation.
An example is presented in Figure 1. In this case the mold temperature decreases during the time period when the mold stays open. If this time is not considered in the simulation, the prediction of the whole cycle time, as well as the prediction of the cooling time or curing degree, will be erroneous. Besides, the predicted quality of the parts produced can deviate from reality.
In SIGMASOFT®, such non-productive times can be defined and varied separately in the simulation. Therefore, besides calculating the whole cycle, it is also possible to perform trouble-shooting of problems at each of the production stages. Through the utilization of simulation it is possible to decide if changes in the process definition are enough to solve production problems, or if the mold has to be reworked to achieve the desired quality and productivity goals.

Continue readingWith the process-oriented approach of SIGMASOFT®, the injection molding simulation for elastomers is no longer limited to predicting the cavity filling while designing the part or to answer questions regarding a balanced filling. Based on an accurate simulation of the curing reaction (vulcanization), it can be used for designing the mold, identifying process windows and troubleshooting during production.
The process-oriented approach of the Injection Molding Simulation Software SIGMASOFT® allows for the easy and exact consideration of all relevant information regarding mold and process into the calculation, beyond the part and runner geometry.
Schaumburg, IL, July 25, 2012 – At the recent DKT Conference in Nuremburg, Germany, SIGMA Engineering GmbH, Aachen, presented the latest functionality expansions of its 3D Injection Molding Simulation Software SIGMASOFT®. The focus of the presentation was the software’s ability to reduce development and production costs through new developments in process simulation.
Many factors in elastomer injection molding have an influence on product quality and costs. To ensure a competitive advantage, the whole manufacturing process must be considered. Since the design stage has the largest influence over the total costs of a part, this is where the savings start with SIGMASOFT®.
By using process simulation, feasibility and rough process parameters can be evaluated. Parting line and venting channels can be worked out, as well as the optimal type and positioning of the injection drop point. Where are weld-lines acceptable? Where do they need to be avoided? Do inserts need pre-heating? Which level of vulcanization should be reached and how much time and what temperature are needed to achieve this level? Important factors regarding part quality are optimized in this way, through the algorithms in the software.
A mold, which will be used for producing the part, can now be developed. Decisions must be made at this point, which can incur substantial costs: How many cavities can be designed in the mold (clamping force and required pressure)? How should the runner system be designed to obtain balanced cavity filling and the same compound quality in every cavity? Is there need for a cold runner? What heat-output is needed and how must the heating system be configured? Are the heated clamping plates adequate? Where should control points for the tempering be positioned?
The simulation is able to answer all these questions and allows reaching the desired quality with minimal effort (time and energy). In this way, the process stability is guaranteed before the mold is even built. Costs can be reduced significantly during development and existing processes can continue to be improved. This is all accomplished while substantially reducing rejects and material waste, thereby getting to the first good part much faster.
The latest developments in the software’s thermal solver allows for the exact integration of all mold components. As a result, an accurate reproduction of the real temperature profile in the mold is possible, even over multiple injection molding cycles. The simulation definition is optimized for the requirements of process engineers, so that complex detail questions can be examined from a practical perspective without requiring extensive knowledge of simulation software. For example, it can be determined how heating cartridges influence mold temperature and part quality, simulating them with their respective electric power and control.

Continue readingThanks to a completely reengineered solver technology and a revolutionary meshing concept, with SIGMASOFT® Version 5.0, the simulation time required in elastomer applications can be reduced by up to 80%. With this dramatic speed-up, simulation can now be integrated in the elastomer processing on a daily-basis, both for part design and process troubleshooting.
Figure 1 –With the new solver technology and the use of “unstructured meshes,” SIGMASOFT® Version 5.0 reduces the calculation time by up to 80% in the simulation of elastomer injection applications.
Schaumburg, IL, July 25, 2012 – At the DKT conference in Nuremberg, Sigma Engineering GmbH, Aachen, presented SIGMASOFT® Version 5.0, the latest release of its process-oriented simulation software. With a completely reengineered solver technology and a new meshing concept, calculation times have been dramatically reduced, while keeping all the advantages of accuracy and user friendliness of a complete 3D-simulation approach.
“With SIGMASOFT® Version 5.0, we have achieved a major breakthrough in injection molding simulation,” explains Dr. Marco Thornagel, Executive Manager at Sigma. “Some years ago, users had to wait sometimes days to get the results of a simulation. It was not viable to use simulation to support every-day production activities, or to quickly optimize products. Now, however, simulation can be part of the daily production tools used in the mold shop or in the production floor, to deliver reliable and profitable answers both to design new products and to optimize existing molds.”
SIGMASOFT® is still the only option available in the market to seamlessly integrate all elements in the mold within the simulation. Thanks to the implementation of “Finite Volume” numerical methods, not only can the cavity be considered in the simulation, but also the complete real mold configuration, including tempering channels, heating elements and inserts. SIGMASOFT® is and has always been based exclusively in 3D technology, developed over a quarter century. The mesh required to conduct the simulation is generated effortlessly by the user in only minutes, without requiring any manual optimization.
The new meshing technique in the latest version of the software uses “unstructured meshes.” These are basically “intelligent meshes,” which can automatically mesh finer regions where complex thermal and flow phenomena take place, such as part boundaries, thin walls or complex runner systems. It also can save mesh elements in regions where fewer interactions take place, such as mold boundaries. The calculation effort is reduced and the productivity of the software increases.
Through parallelization, the new solver architecture makes it possible to exploit the complete potential of multi-core technology in state-of-the-technology computers. Beyond a significant reduction in computational time, the technology now allows users to simulate more complicated injection molding processes. This will be now the focus of further developments in the software, according to Sigma sources.

Getting started with live tools…
A flexible tool adapter system can be a big time and money saver, if properly utilized and properly designed for maximum power transmission and accuracy in alignment.
When any metalworking manufacturing facility, whether captive or job shop, makes the substantial investment in a new lathe, they are often looking for ways to streamline the manufacturing process. The smarter you are when choosing the live tools for your job, the more efficient the machine becomes. Finding a supplier of live tools who offers high-quality, high-performance products that will allow you more flexibility on the first big job and into the future in your operation is the key.
The first tool feature to consider is the output needed. Standard ER output or quick-change? Do you need coolant through the tool capabilities? Does the tool meet your requirements for precision and performance, including the necessary torque output to complement the machine? Are the tools designed according to the specifications of the lathe manufacturer?
When you look at an ER output, does it give you enough flexibility or do you need a more flexible machining system that will allow you to use the same tool for different applications. If more flexibility is required, then you may want to consider tooling with a system that features adapters for a variety of tools without the cost of new complete toolholder assemblies for each tool needed. However, when you look at such systems, be sure they feature a rigid polygon drive system design to prevent power transmission and alignment issues. Such systems seem appealing, because the live tool stays in place and only the adapter and collet get changed out with each new tool. However, less sophisticated though inexpensive systems will compromise the accuracy of your work. At that point, the few dollars saved will mean very little, compared to the scrap and downtime resulting.
If changeover time is critical, such as when working on a “family of parts,” the option of a true “quick- change system” might be more
A true quick-change system can be set offline and quickly installed, but it must be considered in light of today’s AND tomorrow’s workload.
beneficial. Adapters can be set offline and ready to go for minimal changeover time.
When coolant-thru tools are selected, it is imperative you first check the machine specifications to be sure your tool is capable of handling the coolant pressure of the machine. In general, your internal coolant live tools should be able to handle 1000 psi or more.
If your live tool is constructed with large, high accuracy bearings, the tool will have excellent rigidity and premium cutting performance, with minimal runout. (0.0002” or 0.006mm is a desirable goal.) The bearings, combined with ground, paired and high accuracy gears, make for tools that are consistent and long lasting. Bore tolerance is absolutely key in maintaining proper bearing load and this factor should never be compromised.
In addition, you should consider the many applications that can be accomplished with the proper live tool. You can purchase speed increasers for higher rpm, gear reducers for added torque, adjustable angle tools for compound angles, multiple-spindle tools for additional capacity, or gear hobbing tools for spline or gear cutting. Most of those items are standard catalog devices, but one more piece of advice: never shy away from the custom tool, when appropriate and justified by the job you have in-shop today, as well as the ones you might have tomorrow. A good tooling supplier will work with you to produce custom tools at reasonable prices, but the supplier must be very reliable, so look for one with grinding, finishing and perhaps even heat treating in-house or very closely monitored, to do such work. Additionally, be certain the supplier has local support and tools can be repaired or reworked quickly and correctly.
The workpiece materials are always a driver. Those of you doing medical machining know this well. Buying a less expensive or lower featured tool to work cobalt chromium and titanium is a really bad idea, to be blunt.
Custom tools, though usually dedicated to a particular application, can be the best solution, IF the design and construction of the tool is solid and the application engineering and after-sale support is available locally to service it.
On a practical level, always check the supplier for inventory and source of supply. Today, when your customers are demanding faster response times and more cost off-loading, you can expect the same from your tooling supplier. Likewise, application and engineering assistance should be available from local sources to support your tool choices.
The bottom line is the bottom line for most of us today. However, always consider the future jobs when purchasing tooling systems for your new and existing lathes. What might seem a bargain might not be, after the first big job is completed.
DIN and ABEC standards are the norm in industry and your supplier should be willing to supply all necessary documentation on request. Shortcuts on quality are never, repeat never, worth the short-term savings.
I hope this short primer on tooling will assist you in equipping your next machines.

HT Series quick-change tool adapter system from Heimatec requires only a single clamping bolt turn for changeover. Click the image to view the animation.
Heimatec, a world leader in live tools, angle heads and multi-spindle drill heads, announces immediate availability of its newest development, the HT Series quick-change tool adapter system. With the HT Series onboard, users do not need to change tooling, only the adapter and that action is accomplished with a single clamping bolt. In this way, collet assemblies can be preset outside the machine tool, then simply swapped out as needed.
Whether a one-off job shop or long run production department, downtime on any machine tool is costly and the HT Series reduces changeover from an average of 15-20 minutes down to about that many seconds. The tool head stays in the machine, so less probing is needed after the changeover, as well.
HT Series offers users a lower initial investment, minimized tooling time, reductions of tooling quantities and related costs, plus considerably lower inventories. Further savings are realized by the high degree of flexibility in the system, the shortest gauge line of any system on the market, meaning no additional tool length consumed, standard coolant-through design, exceptional repeatability to 0.0002” and easier handling of the components, resulting in lower setup costs.
This new quick-change system is available from Heimatec with all common outputs, including collet, extended collet, collet with tension and expansion for tapping, weld-on, weld-on extended, arbor, hydro-chuck, indexable insert holder, shrink fit and blank/plug design.

Heimatec axial tool with built-in U-tec system
To everything, there is a REASON…turn, turn, turn…
Here’s your best reason to stop by our booth:
At this year’s IMTS, Heimatec will display its live tooling in a unique way…a live demo on a rotating machine tool turret. Come and see the show!
Heimatec, a world leader in live tools, angle heads and multi-spindle drill heads, today announced immediate availability of its newest development, recently unveiled for IMTS.
U-tec is the company’s patented flexible tool adapter system that allows a standard ER output live tool to accept various adapters for different applications. This allows users the ability to have quick changeover of tools on almost any lathe, using a single live tool, without having to commit to a quick-change system on the initial purchase. A facemill adapter, for example, can be quickly positioned into the standard holder, without the need for a completely new base being installed. This significantly reduces inventory costs as well as changeover time, for the busy shop.
Heimatec radial tool with built-in U-tec system
The U-tec system, according to Heimatec Inc. President Preben Hansen, “…represents a real improvement in lathe and mill/turn tooling design. U-tec allows great user flexibility, while a polygonal drive system ensures extremely high power transmission stability and faster set-up with absolutely no loss in performance or accuracy, because the live tool base remains in position and only the adapter and collet get swapped.”
He went on to explain the unique collet nuts on the U-tec system have internal threading for rigid mounting and that this new tool adapter system enables the actual cutting tool to be brought into closer proximity to the bearing, thus further improving performance in use. This benefit results from the short and compact tool length design. Internal coolant up to 2000 psi(140 bar) is provided standard.
Side lock adapter
Every adapter in the U-tec system comes complete with any necessary clamping nuts and adapters are immediately available in face mill style, ER extensions, side lock, shrink fit, hydraulic and blank.
The U-tec system is available for all major turning machines on the market today. Heimatec currently manufactures over 10,000 live tool types.

Integrated Sawing and Machining Center Sets New Industry Standard
Rattunde Corporation introduces the ACS + CFMcurve integrated sawing and machining center, an exciting new technology, at the IMTS show, McCormick Place in Chicago, from September 10-15, in the North Hall Booth #6737. A fully operational system will be producing a variety of parts, demonstrating the fully automated flexibility of this manufacturing center.
The ACS Sawing Machine is the new industry standard for cold saws. It utilizes a proprietary sawing algorithm with servo motor controlled feed to continuously adjust critical sawing parameters during each cut. The results are the fastest sawing times, best surface finish and longest blade life available on the market.
The CFMcurve machining center is a patented Rattunde process that
simultaneously machines each workpiece end, using 12 independent servo-controlled axes. Machining options include: threading, boring, profile turning, grooving, radius edges and angled chamfering. Programming screens guide operators for quick setup on even the most complex part geometry. No special programming is required.
Precision parts are made in one continuous process with no operator intervention. Bundles of mill length stock, up to 16.5 meters (54’) long, are placed in an automatic loader, individually separated and fed to the sawing process. Cut parts are then transferred to the CFMcurve machine for precise finishing. Utilizing advanced CNC controls, linear ball screws and servo motors, all mechanical motion is seamlessly integrated into the machine design for full process control.
The technology incorporated on this manufacturing center delivers production rates and quality unmatched by the competition. For example, a tubular component of 70mm diameter, wall thickness of 5mm, material type ST52-3 BK, with a length of 150mm, machined with a 30 degree chamfer on the ID & OD with a faced end has a saw time of .96 seconds, a machined time of 1.86 seconds and the machine can produce 1,820 parts per hour, inspected for length and automatically packaged. Cut length tolerance of +/- 0.15mm at 1.67 CPK and a machined length tolerance of +/- 0.05mm at 1.67 CPK are maintained with consistency.
The operator interface saves part files for instant recall when changing parts. Servo motors move all cutting and machining tools to their exact positions and implement saved parameters. No tooling change is required in the ACS Saw within a diameter range of 10mm; there is a 5mm diameter range in the CFMcurve. Tooling change for the complete system takes less than 20 minutes, when necessary.
All critical sawing and machining parameters are monitored and controlled. Clamping forces and position, saw blade torque and vibration, plus machining insert torque are continuously displayed and monitored. Operating limits are set and machine functions stop when they are not met. Saw blade and tooling insert wear is predictable and consistent. Key data for each part produced are stored in memory for statistical evaluation. All guesswork is removed for the operator.
Rattunde sets a new industry standard for manufacturing with this machine, replacing slow and unreliable processes with a complete manufacturing center. Bar feeding lathe machines rely on a slow cutoff process, restrict the length of incoming stock and are not always capable of finishing both part ends simultaneously. Cutting in a conventional saw, dropping parts in a bin and eventually loading them
to a conventional machining center is time consuming, labor intensive and creates excess inventory with a loss of process control.
Additional processes, engineered and manufactured by Rattunde, are easily integrated with the ACS + CFMcurve, including: part inspection stations, washing and drying, automatic packaging and automatic container changing, all available to further automate customer manufacturing. The system being exhibited at IMTS will include part inspection and automatic packaging.
The ACS + CFMcurve is available in three models with diameter ranges from 10mm to 102mm, 10mm to 136mm and 10mm to 169mm, with finished part lengths from 10mm to 3500 mm. All material types can be processed.
