  • General design rules for vacuum forming dies.

    The design of vacuum forming molds includes batch size, molding equipment, precision conditions, geometric design, dimensional stability and surface quality. 1. The size of the batch is used for experiments. When the mold output is small, it can be made of wood or resin. However, if the experimental... read more

    Geometric shape design, design, often have to consider the dimensional stability and surface quality. For example, product design and dimensional stability require the use of a female mold (female mold), but the surface requires a higher gloss product, but requires the use of a male mold (protrusion... read more

    3、The size is stable, in the molding process, the surface of the plastic part in contact with the mold is better than the dimensional stability of the part leaving the mold. If the material thickness is required to change in the future due to the material stiffness, it may result in the conversion o... read more

    The surface of the plastic part, in terms of the range in which the molding material can be wrapped, the surface structure of the visible surface of the plastic part should be formed at the contact with the mold. If possible, the clean side of the plastic part should not come into contact with the m... read more

    Modification If a mechanical horizontal saw is used to saw off the clamping edge of the plastic part, there must be at least 6-8 mm of allowance in the height direction. Other finishing work, such as grinding, laser cutting or jetting, must also leave a margin. The gap between the cutting lines of t... read more

    6.Shrinkage and deformation, plastic shrinkage (such as PE), some plastic parts are easy to deform, no matter how to prevent, plastic parts will be deformed during the cooling phase. Under this condition, the shape of the forming mold is changed to accommodate the geometrical deviation of the plasti... read more
