Plastic Injection molding is used to produce many things such as wire spools, packaging and bowl,bottle caps, automotive parts, toys, optics, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today. Injection molding is the most common modern method of manufacturing parts; It is ideal for producing high volumes of the same object.
Injection molding uses a ram or screw-type plunger to force molten plastic material into a mold cavity; This solidifies into a shape that has confirmed to the contour of the mold.

1. Causes and solutions for product burrs(flash) formed when the injection machine first starts, as well as an incomplete filling after a while of production:
When the machine first starts, the melting in the injection machine barrel flows smoothly with a lower stickiness thanks to a longer period of heating, so product burrs tend to occur. After a while of production, since the melting continuously takes the heat away, the product will not be fully injected due to great stickiness and poor liquidity. This problem can be solved by gradually increasing the temperature of the barrel after some time into the production.
2. In the production process, the product cannot be fully injected, even increasing injection pressure and velocity won’t work sometimes. Why and how to solve it:
In the production process, the melting continuously takes the heat away, so the product will not be fully injected due to great stickiness and poor liquidity. This problem can be solved by increasing the temperature of the injection machine barrel.
3. Causes and solutions for product becoming oval:
A product becomes oval is because the melting is not evenly fed, causing uneven pressure on the circumference of the product thus making it oval. The 3-point injection approach can be adapted to allow for even feeding.
