Latest Case Study

 

Injection Molded Components for an Adjustable Clamp Assembly

This project involved a set of related custom injection molding parts designed to fit together around a split central body. The practical work focused on assembly fit, curved contact profiles, reliable mold release, and repeatability from initial sampling through production. While this adjustable clamp assembly used custom injection molding, the same attention to part integration, dimensional control, and manufacturability can also support suitable metal injection molding applications.

  • Part type: Multi-part adjustable clamp assembly
  • Scope: Mold tooling, sampling and injection molding production
  • Key focus: Mating features, assembly fit and visible surface quality

Featured Case

 

PC Electronics Enclosure with Integrated Hinge

A two-piece PC enclosure made for an electronic product, with approximately 100,000 pieces planned for production. The important work was keeping the housing fit, hinge strength and key dimensions consistent through repeat production.

  • Material: Polycarbonate (PC)
  • Production volume: Approx. 100,000 pcs
  • Project focus: Assembly accuracy, hinge performance, strength and delivery timing
  • Confidentiality: Project files are handled confidentially. NDA available on request.

Project Workflow

 

From RFQ to Approved Parts

Clear steps reduce uncertainty for engineering and purchasing teams.

01

RFQ Review

We check drawings, material, quantity, application and critical requirements.

02

DFM and Tooling Plan

Draft, wall thickness, ribs, gates, tolerances and tooling risks are reviewed before manufacture.

03

Trial and Approval

Samples are checked for dimensions, appearance and fit before production moves forward.

04

Production and Packing

Approved process settings, inspection and export packing support repeatable delivery.

RFQ Questions

 

Before You Send a Drawing

What files are useful for a quotation?

STEP, STP, IGES, X_T and SLDPRT files are preferred. 2D drawings, PDFs, product photos, material, quantity and target lead time also help.

Can you review a part before mold manufacturing?

Yes. We can discuss DFM topics such as wall thickness, draft, ribs, gates, undercuts, cosmetic surfaces and assembly risks.

How quickly will you reply?

Our engineering team replies within 12 working hours after receiving enough project information to begin review.

Can you support US, German and UK buyers?

Yes. We support overseas projects with export molds or molded parts, project communication, inspection and export packing.
