Hard Chrome Screw Barrel

The chrome treatment is mainly for anti-corrosion, and it is necessary to consider whether chrome-plated anti-corrosion is required according to the production of different materials. 

Screw chrome plating advantages: 

  1. Good surface finish 

  2. Will not rust.

  3. Small deformation of original parts during plating

  4.  If the part size is not in place, you can achieve the size by adding a few chrome.



Chrome Plating screw

Hard Chrome Screw Application:

1. The chrome-plated screw is not easy to produce glass fiber products because chrome plating is not wearable.

2. If PS with a low flow index (used for food grade products) is used, a chrome-plated screw is required because the new nitriding screw is easy to stick and yellow from the product.

3. General PVC screws require chrome plating.

4. Transparent products must be chrome-plated. If nitriding is used, the quality of the products cannot be guaranteed, such as black spots and yellowing.

5. Flame retardant grades must also be chrome plated. If nitriding is used, screw life cannot be guaranteed.
