The Surface Gloss Of Plastic Parts With Good Wear Resistance Is Strong

- Jun 11, 2018-

All of the injection molding product, the biggest characteristic is to wear good gloss on the surface of the plastic parts and precision and abrasion resistance on the surface of the mold cavity has a direct relationship, especially some plastic to add the glass fiber, inorganic filler and some paint, they and plastic melt in the runner and cavity with high speed flow, friction of cavity surface is very large.

Good polishing performance parts usually require good gloss and surface state, so the cavity surface roughness is very small, high corrosion resistance many resins and additives have corrosion on the cavity surface effect, good dimensional stability during injection molding, injection mold cavity temperature to reach above 300 ℃. For this reason, it is best to choose tool steel (heat treated steel) which has been properly tempered.

Injection molding processing of injection mould is also very important, give you a brief introduction of its maintenance: first of all should be for each pair of mould record card, detailed records, statistics of its use, care, lubrication, cleaning, rust and damage; In injection molding machine, mold under normal operation, all kinds of mold test performance, and finally forming parts size measured, through these information can determine the existing state of mould, find out the cavity, core, cooling system and parting surface damage. Key tracking and testing of several important parts of mould; Pay attention to mold surface maintenance.
