What is injection molding

Injection molding is the most cost-effective way to make a plastic part at scale and offers consistent quality for low-to-high volume manufacturing.

Molding also has the highest variety of materials, colors, and configurations when compared to CNC machining or even 3D Printing. Beyond materials, injection molded parts can have custom cosmetics, polishes, or surface textures.

At IN3DTEC China factory, your parts will be molded in the most advanced automatic machines and get your parts as fast as days.

how does plastic injection molding works?

The plastic injection molding process at IN3DTEC is resin pellets are loaded into a barrel where they will eventually be melted, compressed, and injected into the mold’s runner system.

Hot resin is shot into the mold cavity through the gates and the part is molded. Ejector pins facilitate removal of the part from the mold where it falls into a loading bin.

When the run is complete, parts (or the initial sample run) are boxed and shipped shortly thereafter.

Types of Injection Molding

Rapid tooling

Rapid Tooling is a fast and cost-effective process to create aluminum or steel injection molds for quick-turn injection molding. It decreases the time and cost of the product.

Over-molding

Overmolding is a unique injection molding process that combines two or more components together.

Insert Molding

Insert molding involves placing an insert or substrate into the mold cavity before injecting it with molten plastic. The insert can be made of metal or any other material that can withstand the temperature and pressure.

Silicone Rubber Injection Molding

Silicone rubber injection molding is a fast way to make elastic, soft, durable parts within two weeks. Ideal for food, medical, seal ring, functional prototypes, and low-volume production.
