Causes Of Warpage Of Injection Molded Products The deformation, bending and twisting of injection molded products are mainly caused by the fact that the shrinkage rate of the flow direction during plastic molding is larger than that of the vertical direction, so that the shrinkage ratio of the parts is different and warped, and it…
Color Strip Color Flower Analysis Of Injection Molded Products The occurrence of such defects is mainly caused by the problems of plastic parts colored with masterbatch, although the color masterbatch is superior to dry powder coloring and dyeing in terms of color stability, color purity and color migration. Coloring, but the distribution, that is, the…
Thermal Spraying Of Surface Treatment Of Die Castings Thermal spraying is the use of special equipment to heat the solid material to a molten or semi-molten state and accelerate the spraying onto the surface of the substrate to form a special thin layer to improve the surface properties of the substrate. 1. Heat source Flame,…
Causes And Solutions For Die Casting Defects 1. Flow marks, stripes Characteristics: The surface of the casting exhibits a localized sag smooth texture that is consistent with the flow direction of the molten metal. This defect has no development tendency and can be removed by polishing. 2. Cold insulation, cold connection Features: A gap in…
Die Steel Quenching Cooling Technique There are four aspects to be aware of when mold steel is quenched and cooled. They are cooling medium problems, cooling equipment problems, clear mold surface covering problems, and manual operation technical problems. 1. Die steel spray quenching method Large-scale complex, especially thick and thin workpieces and die steels, in…
