TSP diamond insert for drill bits
Description: It is achieved in an environment of high temperature and superhigh pressure and thermally stable up to 1,200°C for its insert binder (mainly Si). Its SiC has a similar coefficient of thermal expansion to that of diamond & enjoys very good wear-resistance. Application: Different TSP products with different performances of wear-resistance, toughness, self-sharpening & high-temperature resistance can be used in gem-processing, wire drawing dies, coated cutters, etc. It can be applied on the drill bits for oilfields. Quality Control:1. Strict raw material selection to guarantee impurity below 20ppm; the binder's purity over 99.5%. 2. Advanced blending techniques to ensure thorough & even blending of diamond with binder. 3. Scientific formula & synthesis procedures. We can also adjust formula & procedures as per customers' requirements for the most suitable products. 4. Strict control of other auxiliary materials to guarantee precise dimensions & best quality. Comparison with other producers| Union | Others | Effects to Synthesis Results | |
| Press | Chamber dia over 500mm, Only one in China to use cubic press to get belt press results. | Chamber dia all below 460mm. | Union’s 55,000 ~60,000 bar VS others’ 50,000 bar |
| Raw Material | Well controlled. Fine diamond & Si powders are selected. | 20 minutes crushing diamond & silicoferrite as raw material. Loose size control. | Union’s enjoy good purity & thermal stability. Different sizes available. |
| Processing | Indirect heating method & special chamber structure guarantees even pressure & temperature. | Direct heating & uneaven temperature & pressure. | Union’s products are consistent with narrow tolerance. |
| Management | Experienced operators & experts. Long term cooperation with research centers. | Operators lack of experience of big presses. | Union can ensure products with better & consistent quality. |
| Quality | Wear ratio 80,000 – 100,000. Good heat-resistance. | Wear ratio 30,000 – 60,000. | It can well protect drill bits. |
