1. Dongguan precision casting has high dimensional accuracy, the general linear tolerance is 1%, the angle tolerance is: ±1/2 degrees, and the surface finish can reach Ra 1.6-3.2, which can save material and machining costs.

2. Dongguan precision casting can produce parts with complex shapes, or cast multiple parts into one, eliminating the need for assembly or welding.

3. Exquisite text or LOGO patterns can be cast on the surface of the product to enhance the product image.

4. The casting material has a wide range of properties, heat resistance, wear resistance, corrosion resistance, and the material hardness can reach HRC15-60 to meet the needs of various working conditions.

5. Dongguan precision casting casting production batch. Flexible quantity, from small to large batch production, high efficiency and good repeatability; mold cost is low, and the initial investment of product development is small.

The biggest advantage of Dongguan precision castings is that due to the high dimensional accuracy and surface finish of investment castings, the machining work can be reduced. It is enough to leave a small machining allowance on the parts with higher requirements, even some castings only Leave a grinding and polishing allowance, and it can be used without mechanical processing. It can be seen that the use of Guangdong alloy steel casting method can greatly save machine tool equipment and processing man-hours, and greatly save metal raw materials.

Another advantage of the Guangdong alloy steel casting method is that it can cast complex castings of various alloys, especially high-temperature alloy castings. For example, the blade of a jet engine, its streamlined profile and cooling cavity, can hardly be formed by machining technology. The production of Guangdong alloy steel casting technology can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual knife marks after machining.

The main products of Dongguan Chengmao Hardware Co., Ltd. are: stainless steel; ordinary high, medium, and low-carbon steel; high, medium, and low-carbon alloy steel hardware castings, such as architectural hardware, household appliance hardware, and equipment parts Hardware, power tool hardware, tableware and kitchenware hardware and other castings and machined products.
