1.塑胶呈波浪。济南注塑加工厂解读，因浇口或其它部分狭窄，熔态塑料推动固化塑件前移时，表面产生波纹。Plastic wave. Ji'nan injection molding plant interpretation, due to the gate or other parts of the narrow, molten plastic to promote the curing of plastic parts forward, the surface ripple.

2.塑件呈银纹形。因塑料含水份，混料不均匀，注塑时夹气，添加剂或脱模剂过多。Plastic parts are silver shape. Because of the moisture content of the plastic, the mixture is not uniform, the injection of gas, additives or mold release agent too much.

3.塑胶接口不良。山东注塑加工厂认为，或因气体排泄不足导致两股以上分流混合而产生发状细线或气泡。Poor plastic interface. Injection molding plant in Shandong that, or due to insufficient gas emissions caused by two or more mixed diversion and produce thin hair or bubble.

4.塑件呈现空洞。因塑料在熔料固化期间表面接触低温模壁，收缩集中于厚壁段而造成空洞，或因夹气做成空洞。Plastic parts appear empty. Because the plastic in the melt during solidification of die wall surface contact temperature shrinkage, concentrated on thick walled section caused by cavitation, or because of the air hole is made.

5.塑件欠注或缺料。济南注塑加工厂认为因机械注塑及塑化性能不足，料流不良，浇口截面太细，模壁太薄或泄气不良。Plastic parts under injection or lack of material. Ji'nan injection molding factory because of the lack of mechanical injection molding and plasticizing properties, material flow is not good, the gate section is too thin, too thin or poor mold wall.

6.合模边挤出塑料。因料温及注压过高，或锁模力不足。Extrusion die. Because of the high temperature and pressure, or lack of clamping force.

7.塑件表面呈凹痕。山东注塑加工厂认为因塑件表面误时冷却，因其表面凹痕。Plastic parts surface dents. Shandong injection molding plant because of plastic parts surface cooling, because of its surface dent.

8.塑件呈扭曲变形。因注塑残余应力松弛导致塑件变形扭曲。Distortion of plastic parts. Distortion of plastic parts due to residual stress relaxation.
