What is the Working Principle of High Speed Injection Molding Machine?

High-speed injection molding machines revolutionize the manufacturing process by significantly reducing production times and enhancing precision in part creation.

High-speed injection molding machines rapidly inject molten plastic into molds, enhancing production rates, cycle times, and part quality, making them perfect for high-volume manufacturing in the automotive and consumer electronics industries.

Addition of Plastic Pellets

First, you put plastic pellets into the machine. These pellets are usually treated before they go in, like drying and mixing, to make sure they’re all the same and good quality.

Calentamiento y fusión

When the plastic pellets go into the feed opening of the injection molding machine, they go into a heated cylinder. Here, the plastic pellets get hot from the heating band and screw in the barrel and slowly melt into a flowable molten plastic.

Moldeo por inyección

Once the plastic pellets are melted into molten plastic, they are pushed by the screw into the injection chamber. The injection chamber is a specially designed chamber with an internal shape that matches the shape of the desired plastic product.

Cooling and Curing

In the injection chamber, the molten plastic will fill the cavity in the mold and cool down fast. As the plastic cools, it will gradually cure into the shape you want. Depending on the product, you might need extra cooling equipment to cool it down faster.

Expulsión

Once the plastic is fully cured and hard enough, an ejection device will push the molded part out of the mold.
