• Description: Under normal circumstances, the gloss of the surface of the Household Product Mould(FURNITUREMOULD) https://www.furnituremould.com/product/daily-necessities-mould/ depends mainly on the type of plastic, the finish of the colorant and the surface of the household product mould. However, for some other reason, the surface color and gloss defects of the product and the darkness of the surface are often caused. The reasons and solutions are as follows: (1) The surface finish of the household product mould is poor, the surface of the cavity is rusted, and the mold is poorly exhausted. (2) The casting system of the household product mould is defective. The cold well should be enlarged, the flow path should be enlarged, the main flow path should be polished, and the sprue and gate should be polished. (3) The material temperature and the mold temperature are low, and if necessary, a local heating method of the gate can be used. (4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and darkening of the surface. (5) The plastic should be completely plasticized, but the material should be prevented from degrading, the heat should be stable, and the cooling should be sufficient, especially thick walls. (6) Prevent cold material from entering the part and, if necessary, use a self-locking spring or lower the nozzle temperature. (7) Excessive recycled materials are used, plastic or colorant is of poor quality, mixed with water vapor or other impurities, and the quality of the lubricant used is poor. (8) The clamping force should be sufficient. Click Daily Necessities Mould https://www.furnituremould.com/product/daily-necessities-mould/ to learn about more information.
