EspañolSimply put, Plastic Injection Mold injection molding is a manufacturing process used to make parts and products as quickly and efficiently as possible without sacrificing quality. A molding machine injects liquid plastic or metal into a mold to make a product. Manufacturers can use this technique to create multiple parts simultaneously in rapid succession.
What is injection molding used for?
Injection molding is most often used when a manufacturer needs to manufacture large quantities of plastic products (often over 100 pieces). This method offers many advantages, most importantly low unit cost. Injection molding creates a surprising number of everyday objects. In fact, there's a good chance you're nearby right now. From computer mice to car parts, injection molding is an integral part of our lives.
Injection molding process steps
melt plastic
Inject molten plastic into the mold
Let molten plastic cool to a solid-state
Removal of hardened product from mold
Injection molding process control
When it comes to the quality of molded products, many specific processes must be considered and controlled.
As the key to the entire injection molding process, the temperature has a huge impact on the performance of the mold. Every plastic material has a specific melting point, so different projects require careful adjustment.
Another factor that needs to be monitored and controlled is pressure, which applies to injection molding and mold cavities. Too much pressure can cause the material to squeeze out of the die. Too little will result in an incomplete product.
