模具工艺的发展必须不断满足人们对产品高质量生产(包括操作性能,外观美等)和低成本的追求.当人们可以有效的控制注塑过程,成型材料转换技术又能满足零件的设计要求,以及模具可重复利用且精度和表面质量保持稳定时,这种愿望便可实现了.因此模具需要保证较高的制造精度.人们希望模具尽管在注塑过程中承受巨大的压力仍然能够多次重复使用且质量稳定,长的工作寿命以换回高的投资.除了设计上的考虑和使用过程中的保养以外,模具的可靠性和使用寿命主要决定于模具材料,材料的热处理和模具的制作工艺.
模具装配一般由多个零件构的选取,成,各零件在模具中的功能各不相同,因而需选择适当的材质.组成模具的腔和型芯,决定了制品的外观和表面纹路.因此需要特别注意材料的选取和加工处理.
The molding technique has to meet the ever increasing demand for a high quality product (in terms of both consumption properties and geometry) that is still economically priced. This is feasible only if the molder can adequately control the molding process. If the configuration of the part is adapted to the characteristics of the molding material and the respective conversion technique, and a mold is available which satisfies the requirements for reproducible dimensional accuracy and surface quality. Therefore injection molds have to be made with the highest precision. They are expected to provide reliable and fully repeatable function in spite of being under extreme loads during the molding process, and a long service life to offset the high capital investment. Besides initial design and maintenance while in service, reliability and service life are primarily determined by the mold material used, its heat treatment and the machining operations during mold making.
