Plastic Part Assembly Technologies

We master several assembly technologies for injection-molded plastic parts, selected based on:

• the type of plastic material
• part geometry
• mechanical constraints
• functional requirements of your application

Vibration welding
A process used to assemble technical plastic parts through frictional motion that generates localized melting of the material.

Spin welding
A technique particularly suited for cylindrical plastic parts requiring fast and robust assembly.

Hot plate welding
A fusion process using a heated plate, ensuring high mechanical strength and perfect sealing—essential in industries such as automotive and medical.

Ultrasonic staking
An ideal solution for fast assembly of injection-molded plastic parts, especially for high-volume production.

These processes eliminate the need for adhesives or additives in assembled parts, thus improving their recyclability.

A Comprehensive Approach to Assembly

From design to mass production, we support our clients at every stage of the project:

• feasibility study
• selection of the assembly process
• part design optimization
• industrial development and validation
• mass production

This comprehensive approach ensures reliable, repeatable plastic assemblies that meet your specifications.

Our teams also perform rigorous quality control to guarantee the performance and durability of the manufactured subassemblies.
