What is Plastic Extrusion
Plastic extrusion is the continuous process of shaping a fixed, cross-sectional profile by forcing raw materials in the form of plastic granules though a die. The granules are fed from a top mounted hopper into the barrel of the extruder and then heated and mixed. The melted granules are pushed into the die, which shapes the molten plastic into the desired shape. The compound is then pushed through the extrusion tool, passed through a series of forming gates and is cooled with chilled water.
Plastic profiles are extruded in continuous lengths which is achieved by pulling the finished product out of a die. This is pulled through an automated cutting system and then cut to a pre-determined length.
Plastic Exstrusion Material
We use different materials for custom extrusions
Polypropylene (PP) ：The is a thermoplastic “addition polymer” made from the combination of propylene monomers
Polyvinyl chloride（pvc）： The is the world’s third-most widely produced synthetic polymer of plastic
Acrylonitrile butadiene styrene（ABS）：The is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene
Acrylonitrile styrene acrylate (ASA)：also called acrylic styrene acrylonitrile, is an amorphous thermoplastic developed
Polycarbonates (PC) ： The are a group of thermoplastic polymers containing carbonate groups in their chemical structures

Generally, all thermoplastics: rigid, flexible, semi-rigid, and reinforced profiles including biodegradables such as PC,ABS,PP,PE,PVC,PVC…
Extrusion is a continuous process and therefore it is possible to cut profiles as per customers’ specifications. At the same time, some profiles and gaskets or sealing profiles made in flexible or semi-rigid materials can be supplied in rolls.
It varies according to the type of profile, for non-stock products, it depends on the profile types, and varies between 1000 and 5000 meters.
Yes, we can supply a range of transparent materials whether rigid or flexible, in various grades of opaque according to customer’s specifications.
A drawing or sketch, a photo or a sample,quantity requested,raw material type (if known) and application features. Our engineers will subsequently contact you for additional information for an exact quote for your project.
Yes, we can make co-extruded profiles, these profiles include two or more different materials that are coupled together. It is possible to join rigid and flexible materials, different colors, as well as materials with different mechanical properties.
