Extrusion process 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. Multiple mechanisms affect the size and shape changes in the extruded product and these can be controlled by die design. It contains a description of the extrusion manufacturing process compatible materials and principles of design.

In a plastic matrix they have excellent melt strength and exhibit low die swell. Basically the die is a block of metal containing an internal flow channel that can be divided into three parts. The extrusion of complex profiles can be achieved therefore with minimal calibration of sizing equipment while die design is straightforward. Kostic and others published design of extrusion dies find read and cite all the research you need on researchgate.

We would like to show you a description here but the site won t allow us. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part. The plastic extrusion design guide is intended to help you optimize your plastic profile design and drive cost out of your part. Die design for extrusion can be rather complicated since the size and shape of the extruded product varies from that of the die flow channel.

Plastic extrusion is a high volume manufacturing process in which raw plastic is melted and formed with a die and sizer into a continuous profile.
