Plastic Injection Moulding Spare Parts

Manufacturer abs plastic injection molding spare parts plastic products pp pe injection molding processing

Reasons for defects in plastic injection molding spare parts:
1. Chromatic aberration: a problem that often occurs in the casing and appearance parts.
① Raw material factors:
Including toner replacement, plastic material grade change, and fixative replacement.
② Different types of raw materials:
For example, PP material and ABS material or PC material require the same color, but there is a slight color difference due to different material types, but a limited range is allowed.
③ Equipment process reasons:
A. Temperature;
B. Pressure;
C. Melting time;
D. Influenced by process factors such as different batches of mixing materials and different machine beer.
④Environmental factors: the barrel is not cleaned, the drying hopper is dusty, the mold is oily, etc.
⑤ Factors of the toner itself: Some toners are not subject to temperature, and the products are easily changed by temperature changes.
 

2. Injection dissatisfaction (lack of glue): The general parts are: deep, thin, long, thin, far away from the gate, easy to trap air, and lack of glue in places with sundries in the mold.
① Mold aspect:
A. The design of the gating system is unreasonable. The gating system is the channel for the melt to enter the mold cavity, which has a great relationship with the molding quality of plastic parts. The gates are not parallel, and the position of the gate is not at the wall thickness part;
B. The mold exhaust structure is poor;
C. Impurities or cold materials in the melt block the flow channel;
D. The mold temperature does not meet the requirements.

② Raw materials:
A. The moisture content of raw materials is too large;
B. The volatile matter in the raw material exceeds the standard;
C. There are too many impurities or recycled materials in the raw materials.
