H.D. plastics is an integrated engineering and plastic extrusion supplier on Extruded Plastic Profiles & Plastic Tubing since 2010.
Plastic Extrusion is a high volume manufacturing process in which raw material is melted and formed into a continuous profile shape. The plastic extrusion process is a well-known technique, widely used in the polymerization industry.
In the plastic extrusion, raw thermoplastic material, in the form of small beads is fed from a top-mounted hopper into the barrel of the extruder. Additives such as colorants and UV inhibitors are often used and can be mixed into the resin prior to arriving into the hopper. The material enters through the feed throat (an opening near the rear of the barrel) and comes in contact with the extruding screw tool.
Plastic Co-extrusion capability
The profile with complex cross-sections that are processed by an extrusion process using PVC resin as the base material, adding different auxiliaries and compounding additives. We can make many types of PVC section profiles. Some are also made by Co-extrusion process with different colors.
There are many different types of plastic extrusion profiles, which can be roughly divided into several types.
First, special-shaped plastic extrusion profiles and pipes by PC, PMMA, ABS, ASA for a wide range of industrial applications.
Second, hollow profile extrusion at both ends.
It is a profile with a single hole or a porous section on the cross-section. The cross-section is completely closed. There can be a transverse rib partition in the middle with different wall thicknesses.
Third, open extruded panel profiles.
There is no hollow room on its cross-section, and it is thin-walled profiled materials, such as plastic gutters, staircase anti-slip strips, skirting boards, drawing mirror lines, and other profiles.
Fourth, co-extruded profile
Co-extrusion with two or more plastics with different properties. For example, the baseboard of rigid PVC is compounded with soft PVC at the bottom, and the baseboard has a good seal with the ground. It can achieve a better function with less cost.
