  • What to pay attention to in injection mold

    The shrinkage coefficient of each material is different, and the plastic mold must have a reasonable shrinkage rate. The plastic mold must have sufficient rigidity, otherwise it will deform during clamping and holding pressure, causing "flash". If the product is ejected while opening the mold, the ejector page of the injection molding machine can be set (but some injection molding machines do not have this function).

  • Whether the mold is good or not, mold processing is very important!

    High processing accuracy requirements: a mold is generally composed of a female mold, a convex mold and a mold base, and some may also be a multi-piece split module. Therefore, the combination of upper and lower molds, the combination of inserts and cavities, and the assembly of modules require high machining accuracy. The dimensional accuracy of precision molds often reaches the μm level
