Injection molding is a complicated process, and it is necessary to comprehensively consider the characteristics of injection molding materials, mold structure, injection molding processing technology, etc., in order to be able to form qualified injection molded parts. However, some small problems will inevitably appear in this process, such as black spots, burrs, lack of materials and other defects. Special attention should be paid to the customization of precision maternal and infant feeding products such as milk warmers. Then, what are the precautions for injection molding of milk warmers?
1. Material temperature control. Different raw materials have different temperature requirements. Shanghai Mulan Mold Factory said that the fluidity of cleavage raw materials is poor. It is necessary to increase the fluidity of raw materials by increasing the temperature to ensure that they are within a reasonable range of flow values;
2. Mold temperature control. The mold temperature greatly affects the cooling time of the injection molded part, so when the mold temperature changes, the shrinkage rate will also vary greatly. Different injection molded products have different requirements on the mold temperature. Even for the same milk warmer, the injection molding materials are not used, the use environment is different, the quality requirements are different, and the mold temperature requirements are also different. During the injection molding process, try to keep the mold at an allowable low temperature, which can shorten the molding cycle and improve production efficiency;
3. Control of the pressure and exhaust system. When debugging the mold, the clamping force and injection pressure must be determined to ensure that the air and gas in the mold cavity and core can be discharged from the mold through the exhaust groove;
4. For the size of the milk warmer, supplementary plastic control, after demoulding, the milk warmer will be deformed and warped to varying degrees with temperature changes, which need to be adjusted with the help of fixtures and timely remedies.
Injection molding of milk warmer is complicated to say, but it is actually very simple. As long as you can find a mold factory with strong technical strength and good comprehensive ability, Shanghai Mulan Injection Molding Processing Factory can provide finished product manufacturing solutions and solve problems in the manufacturing process in a timely manner. problem, you can save a lot of worry.
