Plastic Extrusion Die Design Pdf

Multiple mechanisms affect the size and shape changes in the extruded product and these can be controlled by die design.

Plastic extrusion die design pdf.

The extrusion of complex profiles can be achieved therefore with minimal calibration of sizing equipment while die design is straightforward. Basically the die is a block of metal containing an internal flow channel that can be divided into three parts. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part. 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.

The plastic extrusion design guide is intended to help you optimize your plastic profile design and drive cost out of your part. Pdf on jan 1 2006 milivoje m. 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. The adapter section that connects with the output channel of the extruder 2.

It contains a description of the extrusion manufacturing process compatible materials and principles of design. Die design criteria the die is the assembly located at the end of an extruder which contains an orifice used to shape a plastics melt figure 1. We would like to show you a description here but the site won t allow us. In a plastic matrix they have excellent melt strength and exhibit low die swell.
