Cetakan plastik adalah singkatan dari cetakan gabungan yang digunakan untuk cetakan kompresi, ekstrusi, injeksi, cetakan tiup dan cetakan berbusa rendah. Serangkaian bagian plastik dengan berbagai bentuk dan ukuran dapat diproses dengan perubahan pukulan yang terkoordinasi, die and auxiliary forming system. In order to meet the needs of molded parts, we need to pay attention to some matters when selecting plastic molds, and put forward corresponding requirements. Now choose a more suitable plastic mold to meet the following six requirements.
1. High corrosion resistance many resins and additives have a corrosive effect on the surface of the cavity. This corrosion makes the metal on the surface of the cavity dissolve and peel off, the surface condition deteriorate and the quality of plastic parts deteriorate. Karena itu, it is best to use corrosion-resistant steel, or chromium plating and cymbal Nickel Treatment on the surface of the cavity.
2. Ketahanan aus yang baik. The gloss and accuracy of the surface of plastic parts are directly related to the wear resistance of the surface of the plastic mold cavity. Especially when some plastics are added with glass fiber, pengisi anorganik dan beberapa pigmen, they flow together with the plastic melt at a high speed in the flow channel and mold cavity, which has a great friction on the surface of the cavity. Jika bahannya tidak tahan aus, it will wear quickly and damage the quality of plastic parts.
3. Good dimensional stability in plastic molding, the temperature of the plastic mold cavity should reach more than 300 ℃. Untuk alasan ini, it is best to select tool steel (heat treated steel) with appropriate tempering treatment. Jika tidak, it will cause the change of material microstructure, resulting in the change of plastic mold size.
4. Easy to process mold parts are mostly made of metal materials, and some structural shapes are still very complex. Untuk memperpendek siklus produksi dan meningkatkan efisiensi, mold materials are required to be easy to process into the shape and accuracy required by the drawings.
5. Good polishing performance plastic parts usually require good gloss and surface state, jadi kekasaran permukaan rongga sangat kecil. Lewat sini, the cavity surface must be processed, seperti memoles, menggiling, dll. Karena itu, the selected steel should not contain rough impurities and pores.
6. The influence of heat treatment is small. In order to improve the hardness and wear resistance, the plastic mold is generally subject to heat treatment, but this treatment should make its size change very small. Karena itu, it is better to use pre hardened steel that can be machined.
