  • What are the points to be aware of when processing plastic casings?

    (1) The plastic temperature and mold temperature are high, resulting in long cooling time.
    (2) The glue is long. The back pressure should be reduced, the secondary material should be reduced to prevent overhead, and the feed section should be cooled sufficiently.
    (3) The movement of the machine is slow. It can be adjusted from the oil circuit and circuit to make it appropriate.
    (4) The design of the mold should be easy to demould, and designed to be fully automatic.
    (5) The wall thickness is too large, resulting in too long cooling time.
    (6) The nozzle is flowing, which hinders normal production. A self-locking nozzle should be used or the nozzle temperature should be lowered.
    (7) The barrel is not heated enough. It should be replaced with a machine with a large plasticizing capacity or to enhance the preheating of the material.

  • Is it good to do injection molds or sheet metal molds?

    In fact, these two kinds of molds have their own characteristics, which can't be said to be good or bad, and the simple structure of the mold is good. Complexity requires a certain skill to win. Also don't underestimate the gold mold, the complicated jumping pattern, and it is also a test of people's technical ability.

  • What should be paid attention to the acceptance of sheet metal molds, is there any standard?

    1. Subject content and scope of application
    1, 1 This specification stipulates the acceptance methods of cold blanking die and bending die used in sheet metal production.
    1, 2 This specification is applicable to the acceptance of outsourcing, outsourcing, self-cooling punching die and bending die.

  • What is the wall thickness of common plastic parts?

    Common wall thicknesses for different materials of plastic parts:

    ABS: Generally preferred material, the wall thickness is usually 1, 1.2, 1.5, 2, 2.5, 3mm, depending on the size and function of the product.
    PP: Because it is softer and based on shrinkage, it can't be too thick, generally 1, 1.2, 1.5mm.
    PVC: Because the multi-purpose is because the figure is mostly solid, so the restriction is not big.
    POM: Generally 1, 1.2, 1.5, 2, 2.5, 3mm depending on the size of the product.
    Nylon: Because the shrinkage rate is relatively high, the average material thickness and the proportion of bones and bones can be relatively small.
    Kraton: Because most of them are used as mats or not exposed, there is little restriction.
    The thickness of the wall depends on the external force the product needs to bear, whether it is supported by other parts, the number of columns to be supported, the number of extensions, and the plastic material chosen. The wall thickness design of general thermoplastics should be limited to 4mm. From an economic point of view, excessive product design not only increases material costs, extends production cycles (cooling time), and increases production costs. From a product design point of view, an excessively thick product increases the likelihood of creating voids (pores), greatly reducing the rigidity and strength of the product.

  • What kind of material is used for the mold core of plastic mold?

    The first NAK80, you have to know how to describe it in Chinese, you don't have to ask other, "pre-hardened high hardness mirror mold steel", NAK80 hardness and polishing is excellent, but when it comes to corrosion resistance, it is still not as good as S136 If you do not consider the corrosion resistance factor, I am the first to push NAK80, the market price is about 60 yuan / kg.
