Black Photo Frame Extruded Plastic Profiles material introduction

The main ingredient is polyvinyl chloride, which is bright in color, corrosion resistant, firm and durable. Because some toxic auxiliary materials such as plasticizer and anti-aging agent are added in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., its products generally do not store food and drugs. It is a kind of synthetic material which is very popular and widely used in the world today. Its global usage is the second highest among various synthetic materials.

Extruded plastic profiles production theory

1. According to the principle of plastic extrusion die, the word “extrude” is composed of Latin “ex” (leave) and “trudere” (push), which vividly describes the extrusion process of “applying pressure to drive materials to form through the die”. During processing, Zoje extrusion dies usually add powder or granular polymer to the extruder barrel. Under the action of screw or plunger, the polymer moves forward along the screw groove or cylinder and gradually melts into viscous fluid.

2. Through the die set at the end of the cylinder, a continuum similar to the shape of the die mouth is formed. Finally, after cooling and molding, products with required shapes can be formed, such as various plastic pipe rods, sheets, plastic steel doors and windows, films, decorative skirting lines, etc.

The key point of extrusion die design is the core of extrusion production. The technical state of extrusion die is directly related to the stability of extrusion production, the quality of extrusion products, the efficiency of extrusion production and the service life of the die itself. Therefore, when designing the hot spot, the difference between the head and the compressor cavity should be minimized.

3. Due to the performance, pressure, density, shrinkage and other factors of plastic, the correct section shape is different from the real section shape of the product. This factor should be taken into account in the design to make the die with a reasonable section shape.

4. Compact rhythm, convenient for disassembly and assembly. Under the condition of meeting the mechanical performance, the machine head with rhythmic access, tight connection, uniform heat transfer, convenient disassembly and no leakage shall be designed.

5. Select reasonable materials, and select steel with corrosion resistance, friction resistance, good tensile strength and high hardness. Some people must be chrome plated according to the situation
