This is a customized electronic equipment parts, brass die-casting production, tolerance 0.02mm, uniform density, not easy to deformation fracture, corrosion-resistant products.

Features

1. High productivity.

The production process is easy to realize mechanization and automation. General cold pressure room die casting machine every eight hours can die casting 600~700 times, hot pressure room die casting machine every eight hours can die casting 3000~7000 times. And a die-casting mold in the cavity is often more than one, so that the number of production of die-castings also increased exponentially.

2. Castings of high dimensional accuracy.

Its size is stable, good consistency, less machining allowance and have good assembly. The precision of die castings can reach IT11~IT13 level, sometimes up to IT9 level. Surface roughness value is generally Ra08~32, the lowest up to Ra0.4. General die casting only need a few size parts for mechanical processing, some parts even do not need mechanical processing can be directly assembled and used. This material utilization rate is high, up to 60% ~ 80%, blank utilization rate of 90%.

3. Casting organization dense, with high strength and hardness.

Because of the die-casting metal liquid is solidified under pressure, and because of the high-speed filling, cooling speed is extremely fast, so that the casting surface to generate a layer of cold hard layer (about 03 ~ 08mm). The layer of metal grain is fine, dense organization. So the die casting strength and hardness is high, solid wear-resistant. When the die casting wall thickness is appropriate and uniform, its strength is higher.

4. Can die casting complex shape, outline clear thin wall deep cavity castings.

Because the metal liquid under high pressure can maintain high fluidity. Die casting minimum wall thickness of zinc alloy can reach 0.3mm. minimum casting hole diameter is 0.7mm, can cast the minimum pitch of the thread is 0.75mm.

5. Inlay casting method can eliminate the assembly process, simplify the manufacturing process.

In the specific parts of the die casting can be directly embedded in the required other materials of the parts, such as magnets, copper sets, insulating materials and other inserts to meet the special requirements, both eliminating the assembly process, but also simplify the manufacturing process.
