118. What is plastic extrusion?
Now many people are interested in the plastic extrusion. So we introduce some things about it. And if you want to know, you can read about below.
Plastics extrusion is a high volume production tooling process in which raw plastic material is melted and formed into a continuous profile. Extrusion produces items such as pipe, weather stripping, plastic sheeting, adhesive tape, wire insulation. Thermoplastic materials are fed from a hopper into the heated barrel of an extruder. A rotating helical screw inside the barrel pushes the plastic through the barrel toward the die located at the end of the machine. Molten plastic is then forced through the die opening. Thus, the process of forming a continuous piece of plastic by forcing it through a shaping orifice with or without the presence of heat is called plastic extrusion molding.
Extrusion molded plastics can be given many shapes. Due to the flexibility it offers, extrusion molded plastic can be used to produce various custom molds. When looking to design a plastic extrusion, you can consider the following design tips.
Plate with the shape of the part cut through the die with no transition guiding the material. This is a low cost design for low volume production tooling.
In fact, there are many other things about it. If you are interested it, you can search some information online.
