These points must be paid attention to when mold processing
2024-06-27
When the mold is produced and processed, it is generally formed in batches, so we attach great importance to the mold injection molding technician method and process, if the processing is not according to the specified requirements, the injection mold will be damaged.
1. Raw materials generally do not need to be dried, and in some cases, they are baked at 80 °C for 2 hours;
2. The molding temperature range is large, and the heating melting and curing speed is fast, so the molding cycle is generally short; Temperature parameters: The temperature of the barrel is about 200°C, the material temperature is too high, and the silver wire is easy to appear, and the material temperature is too low to make the transparency poor;
3. Mold temperature control: the mold temperature is generally 50-80°C;
4. GPPS has good fluidity, and there is no need for high pressure in beer plastic, so as not to increase the internal stress of the rubber parts due to excessive exertion, which may lead to cracking;
5. The injection speed should be high to weaken the water lines, but because the injection speed is greatly affected by the injection pressure, too high speed may lead to problems such as sticking to the mold during the front or out of the mold and white top cracking during ejection;
