Insert moulding

Why choose insert moulding?

Insert moulding is a manufacturing process in which metal components are placed into a die before molten metal is injected around them to form a finished part. Our proprietary Injected Metal Assembly (IMA) process is a specific type of insert moulding that begins with a custom tool featuring cavities for multiple components. These components are placed into the tool, and molten zinc is injected. The zinc alloy fills the cavities, hardening to create a permanent bond between the components.

Benefits of insert moulding and Injected Metal Assembly:

Strengthened structure:
Reduced assembly requirements
Complex geometries
Design flexibility
Enhanced aesthetics
Common applications of insert moulding:
Electronic connectors
Medical devices
Telecommunications satellites
Automotive parts
Consumer products

Overmoulding

Key features of overmoulding

The overmoulding process creates a finished product by moulding a softer or more flexible material over rigid metal.

Benefits:
Reduced assembly requirements
Enhanced functionality
Ergonomic design
Enhanced aesthetics
Cost savings
Common applications:
Tool handles
Electronic device grips
Medical devices
Automotive interior components

In die casting, insert moulding allows a metal component to be placed in a die, with additional molten metal injected around the metal insert to create a finished part. This eliminates the need for secondary operations such as welding, tapping and machining.

This proprietary manufacturing process joins multiple components by injecting molten zinc into a die holding the parts, creating a single, permanently bonded unit.

Overmoulding involves moulding one material (often a softer or more flexible material) over another material (usually a rigid substrate) to create a finished product. This is typically used for cosmetic, texture or durability purposes.
