Injection molds are almost always formed in batches during the injection molding process. At this time, the injection mold processing method and process are particularly important. If the injection mold is not processed according to the specified requirements, it is very likely to damage the injection mold. To this end, the plastic industry provides an analysis of the injection mold processing method: generally, no boring raw materials are required. In some cases, they are baked at 80°C for 2 hours; the molding temperature range is large, the heating, melting, curing speed is fast, and the molding cycle is generally short; temperature parameters: the barrel temperature is around 200°C, and the material temperature is too high. If it is too high, it is easy to show silver threads, and the material temperature is too low, resulting in poor transparency.
Injection mold temperature control: The mold temperature is generally 50-80 ° C; GPPS has excellent fluidity, and does not need to apply high pressure in the beer plastic (general injection pressure is about 10Mpa), avoid excessive and increase the internal stress of rubber parts- May cause cracking (especially after paint decoration); moderately increasing the injection speed can weaken the watermark, but because injection pressure can greatly affect the injection speed, too high speed may cause problems such as ejection or demolding. Problems such as sticking to the mold and white cracks during ejection.
