SPP Industry | Cunqing

Factory in Cunqing

As a leading manufacturer of high-end, precision and difficult-to-machine parts, SPP Industry specialises in brittle and hard components and our range of diamond grinding wheels can handle the cutting of diamond-hard materials.

Location

The Congqing plant, which covers an area of ​​15,500 m², is a production site for the development, production and precision machining of new materials, where we carry out cemented carbide sintering, technical ceramics sintering and artificial gemstone growing technology, as well as precision machining of new materials.

Examples of new materials include hard metals, technical ceramics, quartz, ruby, sapphire, nickel-based alloy, brittle and hard materials such as nickel-based alloys and titanium, and rare metals such as gold and silver.

From blank forming to precision machining, all steps are carried out in one plant, greatly improving work efficiency. We adhere to the strictest ISO 9001 standards at every stage of the work, ensuring that the quality of our precision parts is controlled and monitored at every stage of the process.
