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.

Hui Ting Machinery Ltd. supplys 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.
