We provide plastic product assembly services including screwing, mechanical snap-in, ultrasonic welding, gluing, packaging, and logistics services. Depending on product complexity and customer requirements (such as volume, lead-time, efficiency, and quality), we will assemble the product either manually or automatically. Whichever assembly method is used, quality assurance is our top priority, as with all of our manufacturing services.

  • Injection Molded parts (ABS, PC, PP, POM, PS, PA, PVC, PMMA, and all additives, exotic polymer materials (LCP, PEEK etc) and polymer composites)

  • Transfer Molded parts (silicone rubber, natural and synthetic rubbers etc)

Metal Products Assembly

We have great experience in providing metal products assembly services including; screwing, welding, tubing, sheet forming, mechanical fitting, packaging, and logistics services.

Relative to plastic parts assembly, metal products require more experienced operators to use specialist fixtures, processes, tools, or equipment as metal component assembly requires greater precision in dimensions and greater care in handling. Lack of the appropriate experience in this type of work results in high reject rates and assembly difficulties, imposing more stringent and more regular inspections by QC, at higher frequency (15 minutes or shorter). Here is a summary of our metal working capabilities:

  • Screwing

  • Drilling

  • Welding

  • Forming

  • Stamping

  • Metal parts assembly

Electronic-Mechanical Product Assembly

For many products, our clients require full product assembly, integrating components or material they source from other regions or other manufacturers. This requires us to act as a project manager and product assembly provider, wherein we collect and goods-inwards inspect parts supplied to us by the client, before performing final product assembly in-house.

Here are our value-added services for full product assembly:
