Precision Insert Collars Engineered for Reliability and Performance

At Advanex UK, we are a leading manufacturer of insert collars—critical components used to reinforce plastic mouldings and ensure secure, high-strength assemblies in a wide range of industries, including automotive, medical, consumer electronics, and industrial products.

Manufactured to exacting standards, our insert collars are designed to optimise joint performance, improve product durability, and support advanced design solutions where space, weight, and reliability are key.

What Are Insert Collars?

Insert collars are precision-engineered metal rings or sleeves that are moulded into plastic components during the insert moulding process. Their primary function is to:

• Provide mechanical strength to mating areas

• Improve load distribution in plastic parts

• Prevent wear, cracking, or thread damage over time

• Support repeated assembly and disassembly

Common applications include fastening points, pivot joints, rotating assemblies, and structural reinforcements in products where plastic alone cannot provide the required performance.
