Necessary post-treatment for highly stressed wire bending parts and Wire formed parts

To optimize the performance and service life of bent wire parts and wire formed parts, special treatments and post-processing are necessary:

Heat treatment
One of the most important post-processings is heat treatment:
- Stress relieving to reduce internal stresses that arise during the bending process
- Hardening and tempering to improve mechanical properties such as strength and wear resistance
- Normalizing to refine the structure and homogenize the properties

Surface treatment
Various surface treatments can further improve the properties of the parts:
- Galvanizing (e.g. Galvanizing, chrome plating) for corrosion protection
- Phosphating as a basis for further coatings
- Powder coating for decorative and protective purposes
- Anodizing of aluminum parts for improved hardness and corrosion resistance

Mechanical post-processing
In some cases, mechanical post-processing is required:
- Grinding to improve surface quality
- Polishing for high-gloss surfaces
- Deburring to remove sharp edges

Cleaning
A thorough cleaning is often necessary:
- Removal of oils and greases from the manufacturing process
- Removal of oxide layers or other contaminants

Special treatments
Depending on the application, other special Treatments such as surface treatment may be required:
- Shot blasting to increase surface hardness and improve fatigue strength
- Coating with Teflon or other plastics for special sliding or non-stick properties

The choice of suitable post-treatment depends on various factors, such as the material used, the specific loads in use and the desired properties of the end product.
Careful selection and implementation of post-treatments is crucial to ensure the quality and reliability of highly stressed wire bending parts and wire formed parts.
