plastic extrusion die design austria

Plastic profile extrusion is a molding method in which plastic resin is continuously melted, pushed through a die with the desired cross-section (a “profile”), and then pulled through a water bath until fully cooled. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part.

In die design, problems often occur because the product designer has little or no appreciation for the impact of product design details on the ease or difficulty of extrusion. In many cases, small design changes can drastically improve or degrade the extrudability of the product.

Plastic Flow, LLC Plastic Flow's extrusion die design software, polyXtrue, is based upon a unique and proprietary theory that simulates flow of polymers taking into account not only the shear viscosity, but also the elongational viscosity of the polymer.

Plastic Extrusion is a high-volume manufacturing process in which Seven Trust plastic is melted and formed with a die and sizer into a continuous profile. For more i...

Extrusion line for plastic laces Die forming typically occurs immediately after polymer melt has exited an extruder. The most basic process involves guiding the stream of molten polymer under pressure through a die, which three distinct regions: manifold, approach, and lip.

Extrusion Dies Inc. (Chippewa Falls, WI) recently developed a method that allows the opening or closing of the die lip with a single screw located at the end of the die. This device is called Fast-Gap and it allows the die gap to be changed ±2.5 mm while the line is running.

Result suggests that plastic film is the most generated product of the extrusion process. The most commonly manufactured products on the market are those with continous demand but simpler die design. The hardest task of this thesis was to collect prices of extruders and extrusion lines. Order has to be made first in order to inquire prices.

Die Assembly is available in a 2”, 4”, or a 6” width. Horizontal or vertical design for extrusion sheet applications. The universal design has a gap adjustment from 2-40mils. Die is designed to provide a uniform film extrudate thickness of the cross sectional area, eliminating torn edges and uneven sheet film or ribbon film samples.

The latest version of polyXtrue software for the design of polymer extrusion dies has several new features, announced Plastic Flow. PolyXtrue software provides engineers insight into the performance of extrusion dies in the early design stage. It captures accurate quantitative information on the flow inside the die as well as in the extrudate ...

EDI® Strand Dies EDI strand dies for plastic pelletizing are designed to provide uniform pellets of resin following its extrusion through a strand die face. Whether virgin or reclaimed material, once the resin is extruded and cooled, the strands are cut at a very high speed yielding pellets of a prescribed size for optimal processing in ...

For long runs, a fully streamlined die is your best bet. Daniel Cykana has dedicated his 40+ year career to profile extrusion. He worked in the Advanced Technology Group of Bemis Mfg. Co., Sheboygan Falls, Wisconsin, for 32 years, specializing in die and product design and processing.

Die Development Developing an extrusion process is a complex and expensive engineering task. It incorporates numerous interacting phenomenon that are hard to predict with accuracy. Polymer flow physics is often sensitive to changes in temperature, pressure, speed, pull force, friction and unique properties of each type of material. Therefore, design of custom extrusion tooling heavily…
