Surface Spray Coating
Features
With the aim of enhancing the anti-corrosion resistance strength of out bimetallic screw, our Co. had, in the year 1997, imported from Japan a spray coating equipment and after repeated testing, had discovered that this kind of coating treatment can produce a 0.15-0.2 mm coating single thickness of Wc/Co, CrC/NiCr anti-abrasion acd anti-corrosion resistance surface.
- Coation Density : 98-99.8%
- Hardness Degree : Hv1100-1400 and above
- Adhesive Strength : 10000psi and above.
- Alloy Powder : Wc, NiCr
- Adjustment in powder composition can be made to suit different kind of material substrate
Spray Coating Application
- For screws used in plastic injection moulding machines.
- For surface hardness treatment of parts and accessoried used in the aero-space industries.
- For srews and roller used in plastic extrusion moulding machine, cement manufaturing machine, printing press, paper-making machines.
- For surface hardness treatment of moulds and any metal parts at the casting and ship-building industries.
Coation Features
- Hingh degree of alloy density and hardness with low rate of porosity.
- Even heation of alloy powder with low rate of residual stress.
- Attaining effective spray coating.
- High anti-abrasion and achieving even dis-tribution of hardness.
- High anti-abrasion and anti-corrosion strength.
- High adhesive strength with adjustable coation thickness.
Nitriding Furnaces Special Features
In order to provide high quality surface hardness, an improved method of nitriding whereby a more equitable gas distribution can be achieved is introduced into our nitriding treatment process, so that an even layer of hardness is pbtained on the articles treated.
- Processing Dimensions : Maximum Diameter 1,000mm, Maximum Length 6,000mm.
- Items : Barrels, Screws, Assembly Parts and Oil Cyinder.
