Custom Compression Limiters Manufacturer for Plastic Assembly Applications
Compression limiters are metal sleeves designed to carry the compressive load generated when a bolt is tightened through a plastic component. The limiter establishes a defined load path between the bolt and mating component, limiting direct compression of the surrounding plastic and helping maintain the designed clamp load. Its inner diameter, outer diameter, wall thickness and length must be matched to the fastener, plastic section and required clamping condition.
As a compression limiters manufacturer and factory in China, we produce molded-in compression limiters and press-in compression limiters for molded plastic assemblies. Molded-in types are positioned on the mold core before plastic injection, while press-in types are installed into a molded hole after the plastic component is formed. Custom production can be specified by ID, OD, length, wall thickness, retention profile, material and surface finish, based on the assembly drawing and installation requirements.

Frequently Asked Questions
Common questions from engineers, OEM buyers, and product development teams regarding compression limiter selection and manufacturing.
What is a compression limiter?
A compression limiter is a precision metal insert that controls clamp loads in plastic assemblies and helps prevent plastic deformation during fastening.
How does a compression limiter work?
The limiter transfers fastening loads through its metal body rather than the surrounding plastic structure.
Why are compression limiters used in plastic assemblies?
They help prevent creep, maintain clamp force, and improve long-term assembly reliability.
What materials are available?
Common options include carbon steel, stainless steel and project-specific materials.
Can compression limiters be customized?
Yes. Custom lengths, diameters, knurling patterns, coatings, and installation styles are available.
Do you support OEM manufacturing?
OEM production is available based on engineering drawings, samples, and project specifications.
