Aluminum Alloy Die Casting Enclosure With Painting Silver Surface Treatment

Quick Detail

Description

This is a aluminum alloy die casting enclosure

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
1. The production efficiency is high, and the production process is easy to realize mechanization and automation. Generally, the cold chamber die casting machine averages 50 to 90 times per hour, while the hot chamber die casting machine averages 400 to 900 times per hour, so the production efficiency is high.

2. 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.

3. 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.

4. It can die-cast complex thin-walled parts. 3mm. Die-casting parts can have complex part shapes, while the wall thickness of the parts can be smaller, the minimum wall thickness of aluminum alloy die-casting parts is 0.5mm, and the minimum wall thickness of zinc alloy die-casting parts can reach 0.3mm.

5. Parts of other materials can be embedded in the die casting. In this way, valuable materials and processing costs can be saved, and parts with complex shapes can be obtained, and the performance of the parts can be improved, and the assembly workload can be reduced.
