From raw material to production run, our metal parts die casting manufacturer can provide you with precision machined die casting parts and products, please let us know your production needs, if you are unable to decide the type of your needs, please contact us , our professional team will provide solutions for your needs.
There is no doubt that die-casting parts are not only widely used, but also attract more and more attention. Hongjingyuan metal parts die casting manufacturer specializes in customizing, processing and producing various types of die casting parts. As shown in the picture, custom door handles and custom locks are to customer needs. These are high end hardware processed by our metal parts die casting manufacturer.
Die casting is the process of rapidly filling a mold cavity with molten metal under high pressure. The custom door locks and custom handles with complex shapes in the picture are all cast by die-casting. The first step is to design and manufacture the mold. The second step is to pour the molten metal into the fabricated mold cavity under high pressure. After waiting for solidification, the product is taken out. The following are the tolerance values of die castings.
| Basic size of casting | Tolerance classes | |||||||
|---|---|---|---|---|---|---|---|---|
| greater than | To | CT3 | CT4 | CT5 | CT6 | CT7 | CT8 | CT9 |

The custom handles and custom door locks are shaped and then surface treated to enhance the aesthetics of the custom handles and custom door locks. Several models in the picture are to polish the surface of the product first. Polishing can reduce the surface roughness, make the surface brighter, and obtain a sense of luster. After polishing, electroplating is performed. Electroplating can improve the wear resistance, corrosion resistance and electrical conductivity of the product. and enhance its beauty.
The surface treatment of custom door locks and handles is described in great detail above. If the customer has doubts about the quality of the product, such as whether it really meets the standard of corrosion-resistant lamps, our metal parts die casting manufacturer can provide salt spray test, which is Extensive and commonly used corrosion test methods can be used to check the corrosion resistance of protective coatings and decorative coatings. The test time can be 48 hours or even as high as 96 hours. Strict testing standards guarantee our products, whether it is custom handles, custom door locks and other high-end hardware products are of high quality and low price.
About the choice of materials
Zinc alloy and aluminum alloy are the most commonly used die-casting materials, and our custom door lock and handle can also use aluminum alloy and zinc alloy. These two materials are selected according to the needs of customers.
The following are the properties and characteristics of these two metal materials, if you cannot decide which material to use, please contact us.
| Physical properties of three commonly used alloys | ||||||
|---|---|---|---|---|---|---|
| Material | Density g/cm^3 | tensile strength Mpa | specific strength σb/p | Elastic modulus E 10^4MPa | Hardness BHN | melting point °C |
| Zinc alloy | 6.7 | 280~440 | 52 | 7.05 | 65~140 | 385 |
| Aluminum alloy | 2.7 | 110~270 | 57 | 7.15 | 75~120 | 660 |
Metal Material Features
| metal material | Characteristics | Application field |
|---|---|---|
| Aluminum alloy | Low density, light weight, high strength, good electrical and thermal conductivity, good corrosion resistance and easier processing. | Spare parts with larger volume and heavier quality, such as beauty equipment, communication equipment, automobile industry, aviation industry, etc. |
| Zinc alloy | Good casting performance, compared with the other three alloys, zinc alloy is easier to cast, can cast various complex shapes, has good mechanical properties at room temperature and wear resistance. | Home furnishing, 3C products, architectural hardware, toys, beauty equipment, etc. |
Today, this article introduces the products developed and developed by our Hongjingyuan metal parts die casting manufacturer, custom handles, custom door locks, in addition, all kinds of hardware products support customization, welcome all walks of life to come to consult.
