Service&Custom: Plastic Injection Molding Service,OEM plastic products, Fabricate plastic products
Plastic injection is a method to custom plastic products.It utilize pressure to inject the molten plastic into the mold, and then cools it and finally forms into the desired variety of plastic parts. There are specially used for the injection molding machine. The advantages of injection molding method is the production speed, high efficiency, operation can be automated, color varieties, shapes can be from simple to complex, size can be big to small, and high product size precision, easy replacement product, it can manufacture a complex shape parts.Injection molding is suitable for mass production and field forming complex shapes products. The most commonly used plastic are PE ,PP, PS, ABS, PC, PA, POM, PBT, PMMA.
The material to be customed: PE ,PP, PS, ABS, PC, PA, POM, PBT, PMMA.
Place of origin: China , Service to worldwide.

Analyze and solve to the problem of plastic products
Common problems are mainly injection shrinkage, shrinking, do not eat mold, burrs, weld lines, silver, spray marks, charred, warping, cracking / rupture, size tolerance and other common injection problems:
● around the lack of plastic injection molded parts, because unsaturated mode analysis and Solutions
● batch front (burr) Causes and Solutions
● injection surface shrink, shrinkage (vacuum bubble) Causes and Solutions
● crazing (material flowers, spray), burning, gas lines Cause Analysis Solutions
● injection of surface water ripples, rhyolite (flow mark) Causes and Solutions
● injection surface folder waterlines (weld lines), spray pattern (serpentine) Causes and Solutions
● injection surface cracks (crack), the top White (top explosion) Causes and Solutions
● injection surface color, luster bad, because blending, black stripes, black spots Analysis and Solutions
● injection warpage, stress cracking Causes and Solutions
● Cause injection size deviation analysis and Solutions
● injection molding stick, drag flowers (strain), drag the white Causes and Solutions
● injection of transparency, insufficient strength (brittle fracture) Causes and Solutions
● injection material surface cold spots from the skin (stratified) Causes and Solutions
● Cause Adverse injection molding metal inserts Analysis and Solutions
● nozzle salivation (runny nose), drooling, drawing outlet nozzle clogging, mold problems Cause Analysis and improvement measures
● use CAE mold flow analysis techniques to quickly issue an effective solution to the injection site
Performance evaluation of the pros and cons of plastic products mainly in three aspects:
First, the appearance of quality, including integrity, color, luster;
Second, the accuracy of the dimensions and relative positions between, i.e., dimensional accuracy and position accuracy;
Third, the use of appropriate mechanical properties, chemical properties, electrical properties, namely functional
Thus, if due to any of these three aspects in one aspect of the problem, it will result in defective products and extended.
Injection molding products common defect classification
Appearance defects: crazing discoloration, weld lines
Process issues: flash, shrink, lack of plastic
Performance issues: warping, embrittlement
