Special Types of Plastic Fabrication Methods

Fabrication Methods

Plastic fabrication is an integral and important aspect of the plastics industry and has been around for several years. It covers many different production methods, which will be discussed in this blog.

Plastic fabrication is the design, manufacture and assembly of plastic products through a number of different processes. Custom plastic production includes tasks such as testing new plastic types, designing new plastic products, and acquiring advanced machinery for better and faster plastic production.


Compounding is a commercial plastic fabrication process in which two or more plastics are first melted and formed into a mixture/mixture. Once formed, they become a new shape. In the case of mixing, the mixed plastics must be mixed to the right specifications and quantities to ensure the final product is produced as required. As with metal alloys, blending can be used to increase the productivity/performance of the final product. Some of the most common plastic compounds are:

  • Basin Resin
  • Blowing agents
  • Purge compounds
  • Flame-retardants

The Molding

Molding is one of the oldest fabrication processes still being used effectively by many custom plastic manufacturers. Injection molding, rotational molding, and blow molding are all types of molding processes that produce plastic.

  • Compressed molding

The name of this model is mostly explained. The heated plastic is placed in a heated mold and then compressed with a powerful clamping device. The curing process is carried out to ensure the product maintains its integrity and does not deform. Compressed molds are ideal for high strength compounds such as thermoset resins.

  • Blow Molding

Blowing plastic is similar to a glass mold. Paris expands with air first. This air is then pressed into a plastic mold of the desired size. After the mold cools, the plastic is discarded. The blow molding is quite simple and linear, and can quickly produce large volume hollow objects in one piece. Plastic cylinders, fuel tanks and other cavity-based plastic components are mainly manufactured by blow molding.

  • Injection molding

Injection molding is the most versatile molding technique. The injection mold includes different press sizes depending on the pressure and tonnage of the product. Injection molding can produce large parts such as plastic parts for automobiles as well as small plastic parts for surgical applications. Injection molding is a slightly more expensive technique for molding plastics and is used only for producing plastics that require a high melting index.

Plastic Extrusion

Plastic extrusions are used to produce plastic sheets, tubes and hoses. In this process, the plastic is first melted and processed into pellets. After being formed into small pellets, they are fed through the die. Many manufacturers prefer this method because of its speed, power and reproducibility. Plastics made this way can also withstand loads better than other types of plastics made because the extruded plastic has no seams.


Thermoforming is a fabrication process in which thermoplastics are softened by heat and then shaped into the desired product. Thermoforming is carried out in various techniques such as: B. bending the plastic sheet on the heating belt and shaping it into the required parts by vacuum forming. In thermoforming, tooling costs are relatively low compared to other manufacturing processes. Because the deep-drawn parts do not have to be processed at high temperatures and pressures.
