Plastics extrusion is a high volume manufacturing process that melts and forms raw plastic material into a continuous profile. Plastic extrusion is a process that creates two-dimensional shapes on length providing the third dimension tubing, edging, moldings fence, deck railing, window frames, weather stripping, adhesive tape and wire insulation and similar products in continuous lengths or short sections.
Extruded products can be utilized as it is, or may be transforming into more complex assemblies by punching, molding, forming and other techniques. The extruded products can provide a cost effective solution to your product fabrication and assembly needs.
The two different fundamental methods of extruding film are below extrusion and slit die extrusion. While the design and operation of the extruder during die is the similar in both methods.
In the form of small beads known for gravity, raw thermoplastic material fed from a top mounted hopper into the barrel of the extruder. Also in the extrusion of plastics additives such as colorants and UV inhibitors either in liquid or in pellet form are often used and can be mixed into the resin prior to arriving at the hopper.
Through the feed throat and rotating screw plastic beads are forced forward into the barrel where it is heated to the desired melt temperature of the molten plastic. This leads plastic beads to melt gradually as they are pushed through the barrel and lowers the risk of overheating which may cause degradation in the polymer.

Crafted Plastics Inc has new approaches to the plastics extrusion process of making the specialized extruded plastic product. The approaches include
● Co-Extrusion process is used when two materials and colors must be joined into one part.
● Dual Durometer provides the making of a plastic extrusion where the same family of plastics, but with different hardness, is combined in various combinations-flexible and rigid, flexible and flexible, rigid and rigid. The term also applies when two different opaques are used in combination to make a part.
● The Tri-Extrusion is a process that involves combining three materials or colors when needed in one plastic extrusion.
● Value Added Operations after a plastic profile is extruded, additional work can be done. This work includes drilling, punching, notching, creating round or oval holes, cutting mitres, and doing precise tolerance cutting.
In the process, profile extrusion can be completed followed by adding tape like, film, foam, or magnetic, printing, or close tolerance cutting. Every year many events, exhibitions and conferences take place on plastics extrusion.
An ongoing research and development has brought in improved applications and approaches to the plastics extrusion process. A lot of production lines via plastics extrusion machineries already lined up and this is the evidence of the demand for plastics extrusion technologies and the raw material.
