Regarding mould building
  • Q

    1. Q: What is automatically LSR injection molding?

    A:

        The products can be got off from the molds by air blowing system, no need workers to operate.

  • Q

    2. Q: What is difference for cold runner and hot runner?

    A:

    Cold runner mold price higher than hot runner mold, but hot runner mold material wastage during production more than cold runner mold. So, if quantity is small, can consider to use hot runner mold, and if quantity is large, to use cold runner mold would be better.

  • Q

    3. Q:Why need to confirm split line and material gate before mold building?

    A:

         Split line and material gate effect the mould structure, and mould structure decide mould cost.

    4. Q:What is the difference of mould structure for using liquid silicone rubber injection technics......

    4. Q

    What is the difference of mould structure for using liquid silicone rubber injection technics and solid silicone rubber in hot compress technics?

     

        A

    Liquid silicone rubber injection mold are much more precise than solid silicone rubber in hot compress technics, so, for more complex structure products which can not use solid silicone rubber in hot compress technics, liquid silicone rubber injection technics can solve the problem

  • Q

    5.Q: Why for over-molding molds can not build too many cavities or too large?

    A

    ---For over-molding molds, the precise request are very high, if build too large or too many cavities, it would be very hard to adjust balance when doing mass production.

     

    ---For over-molding together parts, there would be tolerance for each part during mass production. And the lsr mould itself also with tolerance each cavity, the cavities are more or mould are more large, the tolerance would be more large also. So, smaller are better for control to save reject rate.

  • Q

    6.Q: Can liquid silicone rubber injection mould make small holes for products?

    A:

    Can, as can make slider for liquid silicone rubber injection molds, so, the niddles will not so easy to be broken.
