♦  The casting dimension accuracy is high, generally can reachIT11 ~ IT13Level, sometimes even up to IT9 level. ♦  Good surface finish, surface roughness Ra 0.8 ~ 3.2 And sometimes can reach Ra 0.4 ; Die casting compact structure, high strength and hardness: because the liquid metal is cooling and solidification under pressure,Combined with the fill time very short,Fast cooling speed,So in the Die castingIn the near a metal layer on the surface of the grain size is fine,Organization to The secret,This not only make the casting surface has good abrasion resistance and corrosion resistance,Also improve the hardness of the entire casting--Die castingResistance to Given strength than the sand mould in generalcasting To improve 25 ~ 30%, but the elongation decreased ♦  Size stability, good product compatibility. ♦  Die casting can produce complex shape, clear outline, thin-walled deep cavity metal parts: because of the molten metal under high pressure high speed Maintain a high liquidity,Therefore can obtain other process method is difficult to machining metal parts. ♦  For example,The current Zinc alloy die casting a The minimum wall thickness can reach 0.3mm; Aluminum alloy castings can be up to 0.5 mm; Minimum cast out of the aperture 0.7 mm; The minimum pitch of The 0.75 mm. A: We are factory. A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity. A: Yes, we could offer the sample for free charge but do not pay the cost of freight. A: Payment 30%TT in advance. 70% T/T before shippment Chrome Plating Production Line

Chromium is a kind of silver-white metal with a bluish tint. Metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals.
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
