AOXU Mold is a good reputation plastic injection molding company in China. Our injection molding shop equipped 12 sets of plastic injection molding machines, range from 40ton to 800 ton, we provide 24 hours a day, 7 days a week automatically production services. The plastic resin we selected covers a wide range, includes ABS, PC, PP, PA, PMMA, POM, PE etc.

We build the molds for plastic injection molding, at the beginning of the mold design, we take the injection molding into consideration, it allow us to be able to achieve the shortest molding cycle time, minimum maintenance cost. Every second of cycle time and every piece of plastic raw materials we selected would eventually benefit our customers. Low volume production order are welcome as well, it always happened when customer feel the cost is unbearable especially the mold making cost. Aco Mold is able to provide a full range of solutions to lower down your budget for low volume project with good quality. Our experts work with you together to find the best solution for your companies.

Understanding the Basics of Plastic Injection Molding Process 


Plastic injection molding process begins with the gravity feeding of polyolefin pellets from a hopper into the plasticating /injection unit of the molding machine. Heat and pressure are applied to the polyolefin resin, causing it to melt and flow. The melt is injected under high pressure into the mold. Pressure is maintained on the material in the cavity until it cools and solidifies. When the plastic part temperature lower than the material's distortion temperature, the mold opens and the plastic part is ejected.

The complete injection process is called a molding cycle. The period between the start of the injection of the melt into the mold cavity and the opening of the mold is called the clamp close time. The total injection cycle time consists of the clamp close time plus the time required to open the mold, eject the plastic part, and close the mold again, the injection molding machine transfer the resin into molded parts through a melt down, injection, pack, and cool down cycle.
