Why does Jiangmen engineering plastics warp and deform
2020-09-14 2240
Warpage is one of the common defects in injection molding of thin shell plastic parts. Due to the conjecture of warpage deformation, the warpage rules of injection molded parts with different materials and shapes are quite different. When the warpage exceeds the allowable error, it becomes a forming defect, and then affects the product assembly. It is a useful condition for controlling warpage defects to guess the warpage deformation of a large number of thin-walled parts (wall thickness less th

What are the applications of Jiangmen engineering plastics
2020-09-14 2244
Engineering plastics are thermoplastic plastics that can be used as structural materials. Engineering plastics have inductive functions, such as high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation, which can be used in harsh chemical and physical environment for a long time. Advantages of engineering plastics engineering plastics have the advantages of low density, light weight, high specific strength, good insulation, scale stability and cor

What is the melting temperature of Jiangmen engineering plastics
2020-09-14 2342
Although the differentiation temperature of modified ABS plastics is as high as 270 ℃, due to the influence of other process conditions, the resin often starts to change color at about 250 ℃. If the temperature is below 20 ℃ but light color and high gloss products are made, if it is necessary to shut down for 15 minutes or more, the barrel temperature should be reduced to 120 ℃. In order to prevent the differentiation of flame retardant during the start-up or shutdown process of modified fire-re
