Plastics are everywhere because of their versatility, longevity, and simpler manufacturing requirements. Plastic extrusion, along with injection molding, is one of the most common processes for high-volume production. Generally, extrusion is common for continuous profiles that use pipes, tubes, door profiles, and other bulky items.
Industrial applications of plastic extrusion started over a century ago and continued to advance with time. Even today, it is the go-to method for many plastic manufacturing projects because its simple, efficient, and delivers accurate results.
What is plastic extrusion
Plastic extrusion is a process used to create a variety of products made from plastic. It involves melting raw plastic material, such as pellets, and forcing it through a die to create a continuous profile. The profile is then cooled and cut into various lengths. Common products made by extrusion include pipes, tubing, weatherstripping, and window frames. The process can also be used to create complex shapes like rods, wire, and sheet. Plastic extrusion is ideal for large-scale production with minimal waste and is a cost-effective way to make products quickly. It's an efficient way to create a variety of shapes and sizes for a wide range of applications.
Pipes and Tubes
Pipes and tubes are among the most common plastic extrusion products. The die requirements are also the simplest as the only thing you need is a simple cylindrical profile. PVC pipes are also extremely common in the industry but you can find other alternatives as well. Whatever material you use, there are high chances that pipes and tubes went through plastic extrusion.
Forming principle Extruders:
The extrusion method of a plastic extruder generally refers to melting the plastic at a high temperature of about 200 degrees, and the molten plastic forms the required shape when it passes through the mold. Extrusion molding requires a deep understanding of plastic properties and rich experience in mold design, and is a molding method with high technical requirements.
The extrusion method is mainly used for the molding of thermoplastics, and can also be used for some thermosetting plastics. Extruded products profiles are continuous plastic profiles, such as extrusion plastic tubes, rods, wires, extrusion plastic plates, plastic extrusion films, wire and cable coatings, etc. In addition, it can also be used for mixing, plasticizing, granulating, coloring and blending of plastics.
Features of Extrusion
Extrusion can realize continuous and automatic production. The production operation is simple, the process control is easy, the efficiency is high, and the product quality is stable. The cross-sectional shape of the product can be changed according to the different requirements of the extruded profile. Its products are extrusion pipes, extruded films, extruded cables, monofilaments, rods, plates, extrusion foamed sheets, hollow products and profiled materials. It has a wide range of applications, such as processing most thermoplastics and some thermosetting plastics, blending modification, plasticization, granulation, dehydration and coloring by extrusion. Extrusion equipment has low cost, less investment, quick effect, small production area and clean production environment.
