Shenzhen Haorui Industrial Technology Co., Ltd. 

Founded in June 2006, the company is a professional enterprise specialising in the research, development, manufacture and sales of non-standard industrial ceramics, cemented carbide (tungsten steel), and all kinds of metallic and non-metallic precision mechanical parts.

After more than 15 years of development, we have accumulated rich experience in the industry and cultivated a group of professional technicians. We have a perfect production process and quality management system, as well

as a set of precision machining equipment and testing equipment. At present, we have more than 3,000 customers at home and abroad, and have cooperated with more than 30 colleges and research institutes, and have a highreputation and good word of mouth in the same industry, the company's overall strength is in the leading position in the industry.

Porous ceramic suction cups


Porous ceramics are ceramic materials with fine pore structure. They are widely used in various fields due to their high porosity, high air permeability, high thermal stability and high mechanical strength. Among them, vacuum suction cups are an important application direction of porous ceramics.

Porous ceramic materials include alumina and silicon carbide, which have excellent physical and chemical properties and can maintain stable performance in harsh environments such as high temperature, high pressure, and corrosion.

Porous ceramic materials have the following performance characteristics:

1. High specific surface area: porous ceramic materials have a high specific surface area, which is beneficial to adsorbing gas molecules and improving the adsorption performance of the vacuum suction cup.
2. High temperature resistance: porous ceramic materials have a high melting point and can maintain stable performance in high temperature environments.
3. Corrosion resistance: porous ceramic materials have good chemical stability and can resist erosion by various corrosive media.
4. Wear resistance: porous ceramic materials have higher hardness and better wear resistance.

We can customize components in ways that perfectly match with the shape and material of the wafer, with your equipment and conditions.We will respond to your various dimensional and material needs to match your exact specification.Even if you require only a single piece for evaluation, do not hesitate to contact us. We are eager to customize chucks for multiple workpieces or for your testing purposes.
