Pretreatment of the material
Generally speaking, it is not necessary for drying process, but if it is in damp circumstance, it need for drying treatment. Drying temperature: 80-100° C, drying time:2- 4 hours.
Injection parameters
In the process of processing, the processing temperature should be strictly controlled.
- Blow molding temperature: 160-190 ° C(under special condition, may control the temperature at 200° C)
- Injection pressure: 20-120Mpa
- Injection time: 2-4s
- cooling time: 8s-20s.
- mold temperature: less than 50 ℃, conducive to fast molding products.
- When in-mold crystallization, the mold temperature should be controlled at 100-120 ° C.
Treatment after processing
No need for after treatment, However, some of the more demanding products can be placed in water at 80 ° C -100 ° C or infrared heat treatment (out of mold crystallization), the time is about 3min, or can be heat treated in the mold at 100 ° C -120 ° C or in the oven 2-3 min, the heat distortion temperature of the treated product can reach above 100 °C, and other mechanical properties will be better.
