400 Ton Machine Aluminum Alloy Die Casting Anodizing Grey TV Holder With Rosh

Quick Detail

Description

     This is a aluminum alloy die casting TV holder

     die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity. The mould cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used. 

Note

Advantages of die casting

• Die-casting parts have high dimensional accuracy and high surface quality. The general tolerance grade of die castings is IT13~IT15 in GB/T 1800-2009, and the higher accuracy can reach IT10~W 1 1. The surface roughness is 3.2~1.6 bucket m, and the local roughness can reach 0.8 bucket m. Because of the high dimensional accuracy and high surface quality of the die-casting parts, the less demanding die-casting parts can be used directly, avoiding machining or using less machining, which improves the utilization rate of the alloy and saves a lot of machining costs.
• The mechanical properties of die castings are relatively high. The molten metal cools quickly in the die-casting mold and crystallizes under pressure. Therefore, the layer near the surface of the die-casting part has finer grains and dense structure. Both strength and hardness are high.
