pp renewable materials, plastic-Xin (certified), Dalingshan recycled materials

 ABS renewable materials of some description, you know? Dongguan City-Xin plastic pumping plant material ABS renewable materials tell you the color of relatively pure, relatively homogeneous material sources close to the original raw material of pmma renewable materials, become a material; the source of the complex, messy colors (black material), the source of all the clutter brands, various viscosities, various parts broken material mixes, commonly referred to as two material bopp renewable materials, there is no absolute standard! 475 renewable materials such as primary material is also ABS renewable materials, stable performance, low impurities. Secondary materials ABS renewable materials, flow, mechanical properties, the color is not stable gpps renewable materials, use only low-level 475 renewable materials. Segmented injection rate of fire and pressure relationships: a segmented injection molding process, regardless of the filling process with a couple of changes in its only a pressure injection pressure that once pressed, and packing stage regardless of its speed paragraphs dwell only keep one can be. 2, sub-injection instance: ⑴ same finished product can be molded using a smaller clamping force, which can be extended machine tool life; ⑵ deceleration segment master the correct packing switching point can effectively ensure the quality and stability; ⑶ molded plastic flow too good, in order to prevent low-speed burr take plastic injection, but not the principle of the raw material is cooled and solidified, the molten resin through the flesh to be further increased at the rate of fire quickly filled cavity, flow marks (is gradually melted butter to the gate of the center presented striped pattern) is the initial junction resin flow into the mold cavity and between the resin followed by rapid cooling flows formed due. ⑷ into the plastic mouth (ie, gate) thick molded parts, the rate of fire too quickly can cause turbulence, cold material is easy to form the residual channel flow marks, it should be slowly pushed a cold low pressure into the plastic material first, so that the back plastic smooth entry. ⑸ nozzle injection molding engineering department because contact with the mold mold mold cooling water temperature lower than the nozzle, part of the heat is taken away mold renewable materials, prone to cold material nozzle head, these cold material first injection mold in water the mouth caused by a blockage or silver streaking rhyolite, paracentesis segmented injection can improve this bad. ⑹ precision small parts, gate size fine, and very easy on the most difficult of the gate cavity balanced production, will open the gate of the same size and then use multi-stage injection technology can overcome. pp renewable materials, plastic-Xin (certified), Dalingshan renewable materials provided by Dongguan Chang-Xin plastic materials.
