injection moulds Manufacturers

The cooling time of the part usually refers to the period of time from when the plastic melt fills the cavity of the injection mold until the part can be opened and taken out. The time standard for taking out the part by opening the mold is often based on the part that has been fully cured, has a certain strength and rigidity, and will not be deformed and cracked when the mold is opened and ejected.

If the temperature is too high, the low molecular weight substances in the nucleating agent will be dissected and volatilized, which reduces the active ingredients in the nucleating agent, reduces the improvement effect of brightness, and the higher temperature will destroy some crystal nuclei of PP Huaxia, reduce the middle of heterogeneous nucleation, so that the modification effect is low; If the temperature is too low, the evacuation of the nucleating agent is not good, and the brightness effect is poor. Therefore, selecting a suitable molding temperature is particularly difficult to improve clarity.

UV plastic injection molded parts is a kind of surface treatment technology, the surface of the general plastic injection molded parts, after UV treatment can make the product surface effect more bright, and it is not easy to be scratched, main technological sprayed on the surface of a layer of transparent oil, need to dry after UV light, explain to everybody below the plastic injection molded parts

Several common surface treatment methods for sheet metal processing are: wire drawing, sandblasting, painting, powder spraying, electroplating, anodizing, and silk screen printing. Since the surface of some sheet metal materials does not have the ability to prevent rust and corrosion, effective surface treatment is very necessary.

Corresponding heat treatment process for machined parts will help to increase the hardness, wear resistance and strength of machined parts, and greatly enhance the precision and service life of machined parts.

PEEK material was first used in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts.
