Plastic Injection Molding

Injection Molding

Injection molding is a common manufacturing process for creating parts by injecting molten material into a mold, commonly used in various industries.

 

 Ensures high precision and repeatability.
 Offers a vast selection of resins.
 Suits for complex part geometries

Overmolding

Overmolding

"Overmolding" is a kind of secondary injection molding, where products typically combine a (hard plastic) main body with a (soft plastic) outer cover.

 Improves strength and lifespan.

 Combines different materials seamlessly.

 Offers color and texture options.

Insert Molding

Insert molding

Insert molding is a process where an insert （threads or electrodes） is securely placed in the injection mold before plastic is injected.

 Reduces assembly steps.
 Enhances component durability.
 Lowers production expenses.
