Process introduction
1. The raw material has high purity, less impurity content, and the physical properties of the board are more stable.
2. Using spray drying technology, the material is protected by high-purity nitrogen under fully sealed conditions, which effectively reduces the possibility of oxygenation during the preparation of the mixture, and the purity is better, and the material is not easy to be dirty.
3. Uniform density: 300Mpa isostatic press is used to effectively avoid the occurrence of pressing defects, and the density of the blank is more uniform.
4. The compactness of the gripper inserts is excellent, and the strength and hardness indicators are good: the Sinter-HIP low-pressure sintering technology is used to effectively reduce the pores inside the board and the quality is more stable.
Our carbide gripper pads was done by HIP sintering, it provide extra 30% on bending strength compare to normal quality, which means our tips will be strong enough when meet heavy impact. Also, it will have longer tool life (better wear resistance) for you to use our tips.
*Sinter-HIP is a method of thermal consolidation for cemented carbide wherein the simultaneous application of heat and pressure fully consolidates the carbide during the sintering process.
Main Grade list
It is very important to select the right grade to match the using purpose, need to find the perfect balance between hardness and bending strength, so we have to consider the physical properties of the processing object, as well as the working condition for tools.
