The production process of tungsten carbide generally includes the following main steps:

1. Raw Material Preparation

High-purity tungsten powder, tungsten carbide powder, and a binder (such as cobalt powder) are selected as raw materials. The quality of these materials directly impacts the performance of the final product, so strict screening and testing of raw materials are essential.

2. Mixing and Grinding

Tungsten powder and tungsten carbide powder are mixed with a binder in specific proportions and then thoroughly ground, typically through wet ball milling or another efficient grinding process, to form a uniform mixture. This step ensures material uniformity and affects the final hardness and toughness.

3. Drying and Granulation

The milled mixture is dried and granulated to prepare it f...

Our quality control process is a multi-step system designed to ensure our products meet industry standards and fulfill customer requirements. The process includes:

Raw Material Inspection: We perform chemical composition and physical property checks on all incoming raw materials, such as tungsten powder and cobalt powder, to ensure their purity and consistency.

Production Process Control: Each production stage—mixing, forming, sintering, and grinding—is subjected to strict quality checks to ensure products meet specifications at each step.

Hardness and Strength Testing: Using precision hardness and strength testing equipment, we measure key properties like hardness, bending strength, and impact resistance. For example, our XT6 screw mold model has a hardness of 86.2 and a bendi...
