How do plastic mold factories deal with white edges on products? Generally, people who don’t understand this industry first consider refueling. Why do you say that? Because this is a method that many people who don’t understand plastic injection processing know, but this The method has a shortcoming, which is waste. Is there no other solution besides refueling plastic mold factory? So how is the white edge formed? 　　
White edge is a unique injection defect of modified polyethylene and plexiglass. Most Appears on the edge of the part near the parting surface. The white border is a collection of countless stretch-oriented molecules perpendicular to the direction of material flow and the fine distance between them. There is still a polymer connecting phase in the white edge direction, so the white edge is not a crack. Under proper heating, it is possible to restore the stretch-oriented molecules to the natural curl state and make the white edge fade.　　
Solution: 　　 During the production process, pay attention to keeping the parting surface of the template tightly matched, especially the area around the cavity, must be under truly sufficient clamping force to avoid vertical and horizontal expansion.　　Reduce injection pressure, time and material volume, reduce molecular orientation.　　

Apply oil-based release agent to the white edge of the mold surface. On the one hand, this position is Chinese quality Injection mould not easy to transfer heat, and the high temperature time is longer. On the other hand, the white edge may be suppressed to reduce the appearance of the white edge.　　The plastic mold factory will improve the mold design. If the mold is made of a material with a small amount of elastic deformation, the mechanical bearing capacity of the side wall and the bottom of the cavity is strengthened, so that it can withstand the high pressure impact during injection and the sharp rise in temperature during the working process, and the white edge prone area is given higher The temperature compensation can change the direction of the material flow to make the flow distribution in the cavity reasonable.
