Victrex PEEK 450GL30 plate Manufacturers

PEEK sheet, the Chinese name is polyether ether ketone sheet, is a new type of engineering plastic sheet extruded from PEEK raw materials. PEEK board has good toughness and rigidity, it has excellent fatigue resistance, and maintains good toughness and material stability at high temperatures. With these excellent comprehensive properties, the parts processed by PEEK plates are widely used in automobile connectors, heat exchange parts, valve bushings, deep-sea oilfield parts, and in machinery, petroleum, chemical, nuclear power, rail transit, electronics and medicine, etc. There are a wide range of applications in the field.

Compared with ordinary nylon, MC nylon has much higher physical and mechanical properties than ordinary nylon.

General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.

The burrs, also known as flying edge, overflow, overflow, etc., mostly occurs in the parting position of the mold, such as: the parting surface of the mold, the sliding part of the slider, the cracks of the insert, the pores of the ejector rod, etc. If the overflow is not solved in time, it will be further expanded, so as to form part of the embossed mold collapse, causing consistent obstruction. Cracks in inserts and top bar pores also cause the product to get stuck on the mold, affecting the release.

Anti-static PEEK board performance characteristics: under the conditions of high strength and rigidity, electrostatic conductivity, excellent dimensional stability, continuous working temperature up to 250 °C, non-flammable (UL 94 V0), filled with carbon fiber, graphite and PTFE, low Friction coefficient, wear resistance and self-lubrication, anti-static grade, resistivity 10^6-10^9 Ωcm, better prevent static charge accumulation.
