Current manufacturing industry plastic parts inside the country. Has developed rapidly, especially the manufacturing industry.Automotive parts electronic and electrical equipment, etc. Forming process of plastic products, which are commonly used today.The process of injection molding (Injection Molding)Because of the high production rate and can be produced.Sophisticated workpieces accurately. However, the acquisition of products that are of good quality or defective products. Once throughThe injection process. Generally, depending on the design of the injection mold (Mold design)In addition, the quality of the products that remain subject.The properties of the material (Material properties).And, most importantly, to adjust the setting of the injection molding machine.For example, the temperatures used in injection molding(Injection temperature) the casting speed.(Speed Injection) constant pressure and hold (Holding pressure) and temperature, injection mold (Mold temperature).The challenge is not full injection piece (Short shots).The first most common defects in the injection molding process is a piece of work which is not full injection found in first stage of injection molding. To adjust the volume or length of injection the injection (Shot size) where appropriate. However, if such a problem still occurs. All that has been done to set the volume to the appropriate injection.My solution is: 1. two types of approach to optimize the injection molding machine. 2. guidelines for adjusting the injection moldsGuidelines for tuning the injection molding machine1. increase the temperature of the molten plastic injection.(Injection temperature)2. raise the temperature of injection molds(Mold temperature)3. increase the pressure in the injection(Injection pressure)4. increase injection speed(Injection speed)5. increase the pressure resistance of rotating backwards back.Screw (Back pressure).6. check the wear of the ring.The same time reverse flow (Non-return valve).Guidelines for adjusting the injection molds1. increase the size and/or reduce the length of the.Channel run (Runner)2. Add the position and size of the inlet.(Gate)3. If possible, adjust the size, thickness,Work piece (Wall thickness), with a thickness of.More and more4. check the size and position of the channel.Breathable (Venting) is that enough?
