Our Critical Controling Points

  • Spring Clip
    commission test
  • Raw Material
    hardness test, elongation test, tensile strength test, yield strength test
  • After Plating
    salt spray test, coating thickness test, high temperature aging test

Our Examples

  • Metals stamped contact’s complex forming structure
  • To ensure the parts the same as drawing and meet the function of elastic, Heju using a dozen of operations to forming step by step (see drawing 1), and doing some special treatment for bending mold part.
  • Using axiliary bridge structure layout design to ensure the parts’ dimension stable.

Frequently Asked Questions

Got questions? We have got answers

How to ensure the life time of contacts?

Heju stamping contact life time can reach 10-100 thousand times.To ensure the contact life time, Heju stamping will make material or contacts heat treat.In that way,hardness can keep in 36-52 HRC.

How to solve the problem of large size and small size?

The abrasion of punching cutter,material deformation can lead to the punching hole to large or too small.In practice, Heju stamping will find a solution to the problem according to the specific circumstances.such as: Material testing,regular maintenance of mold parts etc.

How to choose the material to ensure the performance of clips?

To ensure the performance,we usually choose the ECuSn-C with high hardness, toughness and good corrosion resistance. The ECuSn-C contact can ensure 500,000 times life at least.Except the material, the thickness, technology process and others can influence the performance and life time.

How to avoid the elastic part of the spring to produce greater stress (rebound)?

While forming,most of contacts need bending process.If curvature radius is too small, the bending parts will produce large rebound.So the curvature radius must be 5 times larger than the thickness of the material at least.
