Our Precision Die Casting Services
If you have needs of custom metal parts, cncjsd is a die casting service manufacturer that can help. Since 2009, we’ve hold our engineering team and equipment to a high standard to continually deliver strong and durable parts and prototypes. To ensure legendary quality, we operate strict die casting process that ensures that your custom requirements are being met. These are two types of die casting capabilities we provide.
Hot Chamber Die Casting
Hot chamber die casting, also known as gooseneck casting, is a considerably quick process with a typical casting cycle only 15 to 20 minutes. It allows for high volume manufacturing of comparatively complex parts.
The process is ideal for zinc alloy, lean alloys, copper and other alloys with low melting point.
Cold Chamber Die Casting
Cold chamber die casting process is an very important procedure which helps reduce the amount of heat and solve the corrosion problem in machine’s plunder and related components.
The process is primarily used for alloys with high melting points, like aluminum, magnesium, some copper, and ferrous alloys.

Die Casting Surface Finishes
Post-processing and finishing is the final step of precision die casting. Finishing can be applied to remove the surface defects of cast parts, enhance mechanical or chemical properties, and improve products’ cosmetic appearance. There are six types of die casting surface finish options.
| Name | Description | Materials | Color | Texture | Link |
| As Cast | Regular casting finish obtained without the use of high-end tools or machinery. Like Zinc and Aluminum-Zinc parts can be as cast but still keep high corrosion resistance. | All materials | n/a | n/a | - |
 | Powder Coating | Powder coating can be used to spray a free-flowing, dry powder to the zinc alloy and aluminum alloy die casting. Under strong electrostatic and high temperature, the powder will be uniformly adsorbed on the surface of the casting, forming a powder layer that can mask defects very well. | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Gloss or semi-gloss | - |
 | Bead Blasting | Bead Blasting is a process that sprays fine glass beads at high speed onto the surface of die casting parts using compressed air as the powder. The appearance or shape is changed, and the part obtains excellent cleaning and surface preparation for secondary finishing operations. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Matte | - |
 | Anodizing | Mainly for aluminum alloy die casting. Anodizing utilizes electrochemical principles to generate a layer of Al2O3 (aluminum oxide) film on the surface of the parts. This decorative layer of oxide film provides high insulation and wear resistance. | Aluminum | Clear, black, grey, red, blue, gold | Smooth, matte finish | - |
| Electro Phoresis | Used for aluminum alloy, zinc alloy die casting, etc. Electrophoresis applies metallic luster and an unlimited range of colors on the casting parts. It also can enhance the surface properties and corrosion resistance of metal alloy parts. | Aluminum, Zinc, Stainless Steel | Any | Metallic luster | - |
 | Electroplating | Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common. | Aluminum, Steel, Stainless Steel | n/a | Smooth, glossy finish | - |
 | Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Satin | - |

Alloys Used to Make Die Casting Parts
Aluminum Alloys
Aluminum die casting alloy is lightweight structural metal mainly containing silicon, copper, magnesium, iron, manganese, and zinc.
It exhibits high thermal conductivity, electrical conductivity, cutting performance, and small linear shrinkage, making it has excellent casting performance and filling ability.
Moreover, aluminum alloys can maintain good mechanical properties under high or low temperatures because of their small density and high strength.
Commonly used Aluminum alloys:
A380, A360, A390. A413, ADC-12, ADC-1
Zinc Alloys
The main elements added to zinc die casting alloy are aluminum, copper and magnesium.
It provides a good surface finish without the need for secondary processing. Importantly, zinc alloy is more cost-effective and stronger than other comparable alloys.
Also, it has better fluidity and corrosion resistance so they are mainly used for die-casting meters, automotive parts housings, and other complex metal parts.
Commonly used Zinc alloys:
Zamak-2, Zamak-3, Zamak-5, Zamak-7, ZA-8, ZA-12, ZA-27
Magnesium Alloys
The main alloying elements of Magnesium die casting alloy are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium.
It has the advantages of high strength, low viscosity, good fluidity, great corrosion resistance and easy filling of complex cavities.
Magnesium alloy can be used for die casting of mold and thin-wall parts without thermal cracks.
Commonly used Magnesium alloys:
AZ91D, AM60B, AS41B
