How to protect the surface of the spring? Spring surface is generally treated as black (blue), phosphate, electroplating, spray and so on.

In recent years, there was zinc chromate film DACROMET and it has protective layer with excellent corrosion resistance, corrosion resistance coatings 7-10 times, not the presence of hydrogen embrittlement plating process.

Dacromet surface of the product is silver white. Finish the main characteristics and uses corrosion-resistant properties of oxidized black, blue; commonly used to protect the general spring in the air for 3 months, plating protection for demanding general air medium protection three months to 2 years.

Vinston spring machinery Ltd supply spring machine, CNC spring making machine, spring coiler, spring coiling machine and so on.

Phosphate processing capacity is higher than anti-embroidered oxidation treatment, the ability of high temperature 400 ℃ is to protect critical applications such as artillery guns parts, or as a pre-treatment of other non-metallic protective layer, paint, spray, electrophoresis paint and other anti-corrosion ability, wide applicability corrosion ability, especially in electrophoretic lacquer, currently used for automobile surface pre-treatment used special protective anti-rust oil in the refrigerator compressor springs no hydrogen embrittlement, simple process, environmental pollution production.
