PP plastic molding and use


Drying process conditions for injection molding: no drying is required if stored properly.
Melting temperature: 220~275°C, please be careful not to exceed 275°C.
Mold temperature: 40~80 °C, 50 °C is recommended. The degree of crystallization is mainly determined by the mold temperature.
Injection pressure: up to 1800 bar.
Injection speed: Generally, high-speed injection molding can be used to minimize internal pressure. If there is a defect on the surface of the product,
Then use low speed injection molding at higher temperatures.
Runners and gates:
For cold runners, typical runner diameters range from 4 to 7 mm. It is recommended to use a round inlet and flow path. All types of gates can be used. Typical gate diameters range from 1 to 1.5 mm, but gates as small as 0.7 mm can also be used.
For edge gates, the minimum gate depth should be half the wall thickness; the minimum gate width should be at least twice the wall thickness.
The hot runner system is fully available for PP materials.
Typical use in the automotive industry (mainly using PP with metal additives: fenders, ventilation pipes, fans, etc.), instruments (dishwasher door liners, dryer vents, washing machine frames and covers, refrigerator door liners, etc.) , consumer goods (turf and garden equipment such as lawn mowers and sprinklers, etc.).
