Guill Provides Helpful Terms for Extrusion

Guill’s Chief Engineer, Denis Finn,  provides this helpful glossary of useful terms, used in the extrusion business worldwide. He would appreciate any feedback. 

  • Extrusion Die assembly- also known as crosshead, inline tubing die, head, die.  Connected to extruder by feed pipe/flange.  Forms extrudate into desired shape.
  • Tooling- comprised of two components—the tip and the die.  
  • Tip- defines ID of product for a tubing application or locates the substrate in a jacketing application.  Tips are also known as pins, mandrels,
  • Die- defines OD of product.  AKA bushing.  
  • Land length- straight section at end of the tool set. 
  • Gum space- distance between end of tip and back of die land. 
  • Draw down ratio- relationship between ID and OD of tooling vs. the ID and OD of the finished product.  
  • Linear draw- the ratio of the ID of the die and OD of the product.  And the ratio between the OD of the tip vs the ID of the product.  
  • Area draw- ratio between the cross sectional area of the output of the tooling and the cross sectional area of the finished product. 
  • Draw balance- ratio of the outer surface of the draw down cone to the inner surface of the draw down cone.
  • Concentricity- how well centered the OD of the product is to the ID of the product or the jacketed substrate.  
  • Ovality- how round the OD your product is
  • Dead spot- section of the flow where material is allowed to stagnate.  Usually causes burning and degradation issues over time. 
  • Balanced flow- uniform exit velocity over the cross section of the product.  A well balanced flow produces a higher quality product. 
  • Fish eye, gel, unmelt, comet- common terms for unmelted or non-homogenous melt
  • Melt fracture-surface defect in product caused by shear degradation (usually manifests as a grainy/frosted appearance on surface of extruded part.) 
  • Die drool- particle buildup on outside surface of tooling.  Buildup can break off and cause defects on finished product.  
  • Bulk residence time- amount of time polymer spends in the extrusion die assembly 
  • Shear- term to describe a force that the melt experiences as it is forced through the extrusion die assembly. 
  • Viscous dissipation aka shear heat- frictional heat generated as a result of shear. 
  • Viscosity- resistance to flow
  • Cold spot- section of extrusion die assembly that is not adequately heated resulting in imbalanced flow or a thermoplastic freeze off
  • Rheology- science of characterizing a fluid’s behavior
  • Draw down cone- section of molten polymer as it draws down to its final product dimension.
  • Calibrator- device to precisely establish and control the desired product dimensions
  • Stripe-feature to identify or establish orientation of finished product. 
  • Encapsulated-  stripe between outside and inside surfaces of product
  • Embedded- surface stripe with established depth. Typically a percentage of the wall.
  • Surface- stripe only on surface of product.  
  • Window- strip that goes through wall from OD to ID. 
  • Surging- inconsistent melt output that results in product dimension variation..  
  • Coextrusion- any extrusion that uses two or more extruders.  
  • Wire line/pass line- distance between face of extruder to the center line of the crosshead.  
  • Direction of travel- a way to establish production line orientation.  
  • Recommended moisture content- a qualifier of how dry your polymer should be before you process it.
  • Substrate- the material that is being coated in a jacketing process.  Can be wire, bundle of strands, fibers, etc. 
  • Jacketing- covering a substrate with melt.
  • Multi-lumen- a tube with multiple internal cavities.
  • Melt probe- a device to directly measure  pressure and/or  temperature of the melt.
  • Thermocouple- a device to measure temperature of the extrusion die assembly.  Typically used to control heater output. 
  • Heater bands- provide heat to the extrusion die assembly. 
  • Flow distributor- shapes the melt to achieve balanced flow.

The Guill team at Interwire 2019

Guill Shines at Interwire

Guill Booth at Interwire 2019

Interwire, the largest and longest-running wire and cable show, took place between May 13 and May 16, at the World Congress Center in Atlanta, Georgia.  Guill Tooling & Engineering  had quite a turnout at their booth.  Company personnel were able share their knowledge and interact with many potential customers.

At booth #1511, Guill was showcasing some of its latest technology. Featured were the in-line 5 layer extrusion crosshead of Series 800, single-point concentricity extrusion crosshead and Bullet II extrusion head.

Guill’s 800 Series is designed to produce the highest quality, highest material-efficient OD tubing for automotive, medical, appliance and industrial applications. This series produces smooth extrusion and layer definition of fluropolymer and other materials for all multi-layer, multi-lumen medical tubing, as well as fuel line constructions, multi-layer PEX pipe and drip irrigation applications.

The single-point concentricity crosshead uses micro-fine adjustment screws for precise concentricity. This adjustment is a unique feature of the company for the extrusion of thin-walled jacketing and precision ID/OD tubing.  It not only accepts both vaccum and micro-air accessories, but is also ideal for pressure and sleeving applications.

Introduced in 2015, the Bullet was a new extrusion head with fixed center design, multi-port spiral flow design and gum space adjustment. There was no need for fastening hardware, so cleaning and restart were easier. The Bullet II allows quick tooling changes, as the tips remove from the back and the die removes from the front. Guill’s CAM LOCK® deflector removes and installs the deflector and tip with just half a turn. Hassle free air and vacuum connections are available, in addition to reduced downtime and lowered operating costs.  High-volume and low-volume applications are suitable for this crosshead.

Guill Booth at Chinaplast

Guill Tool & Engineering Exhibits at ChinaPlas

Guill Tool Booth at ChinaplasGuill Tool & Engineering, Rhode Island, a global manufacturer of extrusion tooling, recently exhibited at Chinaplas. Chinaplas is the world’s leading plastics and rubber tradeshow with over 160,000 visitors from around the globe. The show was held on May 21-24 in Guangzhou, China.

Guill is committed to expanding their business in Asia, and, according to Matt Christofaro, Sales Executive, this effort is one of the main reasons they attended the show. Guill has been seeking additional sales representatives in Asia for the last couple of years and met with a number of promising candidates while at the show. Christofaro discussed the effort to expand in Asia, stating that, “there is definitely huge potential here. Even a fraction of the market share could be huge.” He added that if Guill is serious about doing business in China, they must attend this show every year.

Tom Baldock, Sales Representative Manager, was pleased to have met with some potential Chinese customers that have Guill heads and would like to work directly with Guill as opposed to working through the OEM’s. Baldock said that “there are Chinese companies that want American technology, which is still perceived by many as the best technology available.”

Guill had an interpreter at the booth which enabled them to meet with a number of customers, large and small, in person at the show. This, according to Christofaro, “was great for both parties.” Christofaro also noted that “there are a lot of companies (many Chinese) with very impressive extrusion lines that were making product right there at the show.”

Guill products featured at Chinaplas were mainly medical tubing dies. Also shown was a customer sample of a transitional wound drain tubing. Attendees were impressed by the fact that it can be created using a continuous process. Guill had inquiries about their 5 and 6 layer automotive tubing. Booth panels showed that Guill also makes dies for products in other industries, such as wire & cable, hoses, corrugated tube, pipe, etc.

Guill Introduces Reciprocating Head

Automated extrusion process drastically changes the extruded profile

Guill Reciprocating HeadGuill Tool, a global manufacturer of extrusion tooling, has released its new reciprocating head. The traditional tip and die assembly is replaced with a linear reciprocating assembly that changes the tube’s profile within a given length. This process is repeated throughout a single extrusion run without interruptions. Cutting capability, in association with the extrusion speed, cuts the finished product to length.

While cost and value stream activities are reduced, quality is improved. Only one extrusion run is needed to produce a finished product, as opposed to multiple extrusion runs with tooling changes along with a manual assembly operation to connect different tubing shapes.  Guill’s new reciprocating head eliminates an assembly operation. It also eliminates in-process inventory. Thus, there is no need for storage of various tubing shapes and connectors needed for assembly, fulfillment of orders and replenishment of finished goods.

Furthermore, the reciprocating head eliminates a connecting piece, allows JIT production and products made-to-order. Lastly, it reduces total run time from receiving the order to shipping.
