  • Plastic Injection Molds - China

    price: contact company for price

    The plates on most of the plastic injection molds have been ground now,

    and virtually all 21 of my dies have been split open and checked. Only

    things left to do is to coat the interlocks and replace the crap Chinese

    tips with DME' s or Mastip tips.

    So far the operator side ( wether being the twin cavity molds or a smaller single cavity mould) fills last / least. I' ve lost a lot of hair over this, if only I could afford, then I would have no doubt it would be the plastic injection molding machine.

    If the exterior walls cool too fast the shrinkage will draw from the center to the perimeter walls. This will cause a void. A small increase in mold steel temp may help. The location of the bubble is at end of fill. This may indicate a venting or a flow entrapment problem. As mentioned PP is not hydroscopic, but surface moisture can still be a problem. This is more evident when the material is stored in silos. Just preheating just not remove moisture. You need a dryer if this is the problem.

    • Business Description: Sometime we are facing the problem is small part but bigger tonnage, I

      am not sure how the product look like, maybe the plastic part is

      necessary need the high clamping force by projection are, normally we

      try to avoid that and adjust on the plastic injection mold design. What can I suggestion is, you can try to use high speed plastic injection molding machine with special small Nozzle Dia. screw and try to run as fast as possible, and normally special product need to custom make or design the manifold, unless the plastic injection mold is using standard manifold, shot weight not consider when injection mold make.

      If everyone would take a second and read the initial question again. Bruno would like to know what the record is for a 1000 ton change time and if it could be done in 10 min or less. There is a big difference between injection mold change and last part to first good part. It is nice to see all the sales folks jumping on the blog and trying to get a sale. I would think it a no brainer that the larger the plastic injection molding machine and the faster the change time to more costly the system and the longer time to pay for the investment in the automation.
