Carbide Cutting Tools, Raw Materials, SC (Solid Carbide) Rods, and more

The main component of cemented carbide comes from tungsten ore. We have our own mines. We start from mining to ensure the quality and supply of raw materials. We control and ensure the product quality from the powder source.

Tungsten ore evolved into tungsten carbide through smelting, and RTP powder was prepared. Over the past 30 years, the company has developed smelting technology, offering comprehensive grades for various machining applications, including nano grade.

RTP powder is made into green part by pressing process. We have three ways of pressing blanks, traditional cold pressing, cold isostatic pressing and extrusion. As well, we possess the ability of soft shaping to reach net-shape products.

Any minor defect may seriously affect the performance of carbide products. The advantages of possessing a complete industrial chain enable us to strictly control the quality of all the production process, which to maintain the stability and consistency of product performance.

According to different applications and customer requirements, cemented carbide products need to go through finishing processes such as grinding to meet the required size and accuracy. We always control the grinding accuracy with more tight tolerance.

After sintering of high temperature, the green body becomes cemented carbide with high hardness. Achteck has the most advanced sintering equipments and match the unique sintering process to ensure the compactness and uniformity of the microstructure after sintering.
