Available materials for die casting:

In the past, the raw materials of zinc alloy die-casting mainly included alloys No. 2, 3, 4, 5, and 7. Now, zinc alloy No. 3 is mostly used in zinc alloy die-casting. Later, there were high aluminum-based alloys ZA-8, ZA-12, ZA-27, wrought zinc alloys Zn-1Cu-0.1T and Zn-22AI alloys. Zinc alloy mainly contains aluminum, copper, magnesium, cadmium, lead, titanium and other elements, of which effective alloying elements: aluminum, copper, magnesium; harmful impurity elements: lead, cadmium, tin, iron. (Zinc alloys are also called zinc-based alloys, and are generally divided into _ element alloys, ternary alloys and multi-element alloys. Binary zinc-base alloys generally refer to zinc-aluminum alloys; ternary zinc-base alloys generally refer to zinc-aluminum-copper alloys; multi-element zinc-base alloys generally refer to zinc-aluminum-copper alloys. Alloy - generally refers to zinc aluminum copper and other trace metals).

Technology and Process

In the past ten years, China's economy has been growing rapidly. The new energy vehicle industry, electronic communication industry, and equipment manufacturing industry have become the country's pillar industries. The development of these industries depends on the manufacturing technology of basic components. As an advanced non-ferrous alloy precision forming technology in the manufacturing industry, aluminum alloy die-casting is being used more and more widely in the development trend of products towards precision, light weight, energy saving and greening. The demand for die castings has also continued to grow.

In the past ten years, the die-casting industry has experienced several major developments. With the further transfer of the world's processing and manufacturing industries to the mainland of China, the die-casting industry has rapidly expanded to the Guangdong region with strong economic and technological foundations, developed industries and excellent infrastructure, and soon formed a die-casting industry. In the industrial-intensive area, with faster speed, higher technical standards and higher industrial goals, there are many outstanding ones. As a professional die-casting enterprise, the performance and quality of its die-casting products are in the automotive industry. The connector industry has made great progress, as well as the affirmation of users. The development of automobile and new energy automobile industry in the Chinese market, connectors, auto parts, help the industry to develop various aluminum alloys, magnesium alloys, and zinc alloy die castings.

Analysis of various types of die casting technology:

1. Vacuum die casting technology

The vacuum device is integrated with the host, the molten metal is sucked from the bottom of the die casting chamber, and the operation of the machine contains the vacuum system.

2. Thixoforming die casting technology

The molten metal is stirred to obtain a semi-solid metal with semi-solid characteristics, and then prefabricated into a billet of the required size and shape, heated, placed in a die-casting machine, and then die-casted.

3. Flow forming die casting technology

Using conventional casting metal, a semi-solid metal slurry with a spherical structure is made, and the die-casting is carried out directly.

4. Injection molding die casting technology

The semi-granular solid metal is added into the die-casting machine, and directly heated and stirred by the spiral body to form a metal with a semi-solid structure, which is then injected and die-casted, and was first used in magnesium alloy die-casting.

5. Pressure die casting technology

The molten or semi-molten alloy is poured into the pressure chamber of the die-casting machine. Under the action of high pressure, it is filled in the cavity of the die-casting mold at a very high speed, and the molten alloy is cooled and solidified under high pressure. High efficiency , High-efficiency precision die-casting.

6. Aluminum alloy die-casting production process

Zinc alloy die casting is a high-efficiency, non-cutting metal forming precision casting method that has developed rapidly in modern metal processing technology. Compared with other casting methods, due to the short process flow, concentrated process, excellent quality, high precision and good surface finish of die casting production, a large number of machining processes can be omitted. Among the die-casting alloy materials, aluminum alloy die-casting, zinc alloy die-casting and magnesium alloy die-casting occupy a larger market share, and are widely used in precision parts of automobiles and new energy vehicles.

7. The characteristics of die casting production are:

1) The dimensional accuracy and surface roughness of die castings are required to be high.

2) The strength and surface hardness of die castings are high.

3) Die casting is the most suitable for parts with complex shapes that are difficult to machine and manufacture.

4) With the mechanization of the production process and the popularization of automation, the productivity of die casting is higher.

5) The assembly operation can be omitted and the production process can be simplified, so as to improve the working performance of the die-casting parts and save energy and consumption.

Post Casting Process

1. Heat treatment: annealing, carbonization, tempering, quenching, normalizing, surface tempering

2. Processing equipment: CNC, WEDM, lathe, milling machine, drilling machine, grinder, etc.;

3. Surface treatment: powder spraying, chrome plating, painting, sandblasting, nickel plating, galvanizing, blackening, polishing, bluing, etc.

Moulds and Inspection Fixtures

1. Mold service life: usually semi-permanent. (except for lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.

Quality Control

1. Quality control: the defective rate is less than 0.1%.

3. Testing equipment: flaw detection, spectrum analyzer, golden image analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine;

4. Provide after-sales service.

5. The quality can be traced back.
