Product Description

The stretching process requires multiple shallow stretching to form. The precision match between each shallow stretching determines the error after forming. And the height ratio of each shallow stretching and the control of the pull mark are very challenging for the engineer's design experience. Stretched parts are different from other processing and cannot be simulated by software.

Technological Innovation

The shell of mobile phone connectors is usually made of stainless steel because it is conductive, thermally conductive, corrosion-resistant, and has a bright appearance. The shell of mobile phone connectors has precision positioning holes, which are locked with other parts. If the precision error is large, it may cause assembly to be unsmooth or impossible to assemble, and the flatness requirements will be relatively high, requiring a close fit with the mating parts. Prevent water vapor or other debris from entering the finished product during use.

Product Display


  • Shell material: stainless steel, aluminum alloy, etc.
  • Application industries: acoustic components, sensors, micro motors, automotive electronics, mobile phones, etc.
  • Shell features: small diameter tolerance after stretching, smooth stretching surface, neat cutting surface.


All the company's processing equipment and testing instruments are Taiwanese and Japanese brands. The technical processing capability is comparable to that of Taiwan. The equipment is adjusted every year according to the product direction of the customer to ensure the product competitiveness of Heju in the customer supply system.

Quality Control

  • Material testing

Each batch of incoming materials can provide a spectrum analyzer test report, which shows whether it is branded material or miscellaneous smelting material. Ensure the authenticity of the shrapnel materials.

  • Precision testing

Forming tolerance and bending ∠R tolerance are measured using imported brand instruments. For example: 2D: ±0.001mm, 3D

  • Performance testing

Using a Japanese stiffness testing machine, the shrapnel can be tested for fatigue resistance, yield testing, and stiffness testing.

  • Surface process test

Use a film thickness gauge to measure whether the thickness of the coating on the surface of the shrapnel meets the standard. Use a salt spray tester to test the corrosion resistance of the electroplated shrapnel.

Application Cases

Our company was established in 2008, specializing in the processing of micro-drawn parts, which are used in mobile phones, micro-motors, sensors and other electronic components. With many years of design and OEM experience, and strong supply chain integration capabilities, we have obvious advantages in the field of precision electronic drawn parts, and are the first-tier supplier of many leading companies in the field of mobile phone micro-motors and optoelectronic module components (such as Jinlong Electromechanical and Bern Optics).
