Development Status

As industrial products, hardware and electromechanical products are closely related to the country's industrial and economic conditions. China's rapid development in recent decades has led to the continuous expansion of the domestic manufacturing industry, and the hardware and electromechanical industry has also become hot, ranging from wrenches and screwdrivers to large Construction machinery has achieved great development and is widely used, but since 2008, with the emergence of the world financial crisis, the domestic economic growth has begun to slow down, especially since 2012, the hardware and electromechanical industry has not been as good as before. Moreover, many high-end high-tech industry products have not mastered the core technology in China and need to be imported.

Industry Prospects

Hardware and electromechanical products need to constantly adapt to the changes in the development of the market. At present, many products are highly competitive. Taking molds as an example, the domestic market share of low-end molds exceeds 99%. However, the market price competition is serious, and the profit margin is extremely low. High-end molds Profits are high but 80% depend on imports. However, many companies have realized this point and began to continuously carry out technological update and product innovation research and development. In the future, the hardware and electromechanical industry will gradually move towards the era of technological competition rather than price competition.

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%.

2. Samples and trial run will be 100% inspected during production and before shipment, sample inspection for mass production according to ISDO standards or customer requirements

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.
