Achtech

The main component of cemented carbide rods is tungsten. We have our own mines and begin the process right from mining to ensure the quality and steady supply of raw materials. By controlling the production from the tungsten carbide rods powder source, we ensure consistent and high product quality.

Tungsten ore is processed into tungsten carbide through smelting to produce high-quality RTP powder. With 30 years of experience, we’ve developed advanced smelting technology. Our grades cover nearly all machining needs, including nano-grade with 0.2 μm grain size. These are used to manufacture premium cemented carbide rods and tungsten carbide rods.

RTP powder is compacted into green parts through a precise pressing process. We use traditional cold pressing, cold isostatic pressing, and extrusion methods. Additionally, we offer soft shaping capabilities to achieve near net-shape products. These processes ensure high-quality production of cemented carbide rods.

After sintering of high temperature, the green cemented carbide with high hardness. Achteck has the most advanced sinterhg «lupments and match the unique sintering to ensure the compactness and uniformity of the microstructure after sintering.

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 contrd the grinding accuracy with more tight tderance.

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 of product performance.
