1. Product Introduction:
The Conical Serials Cemented Tungsten Carbide Buttons are widely used in manufacture of low air pressure DTH bits, High air pressure DTH bits, eccentric overburden drill tools, threaded connection bits, button bits, external thread button bits, pipe bits, DTH drill tools, hydraulic threaded button bits etc.
Our Carbide Buttons are produced with 100% Virgin WC and Co Powders, making the quality consistent in each batch of production. And the HIP sintering furnaces keep the finished product in high productivity and continuity.
The Chemical and Physical Properties of this kind of buttons are listed below:
| Grade | Density(g/cm3) | Hardness(HRA) | TRS(N/mm2) | Grain Size(um) |
| JK10.2 | 14.86 | 89.5 | 2800 | 2.0 |
| JK10.2T | 14.86 | 90.5 | 3000 | 2.0 |
The buttons made of these two carbide grades have strong impact resistance, good abrasive and wear resistance and penetration rate in drilling and digging.
They are mainly applied as the consumption part of the drilling tools, and crowned with 42CrM carbon steel under brazing soldering process or cold mounting process.
2. Product Demonstration:
There are many designs of bullet / parabolic buttons, the types are various depends on the requirement of the clients. So we supply OEM/OEM service to supply tailor-made carbide products to our customers. Below are some iconic products purchased by our customer home and abroad:
3. Process of Control:
To make high quality products, the QA and QC are important processes we pay many attentions. From the raw material purchase to the finished product to be delivered. Each procedure has been strictly traced and monitored. We cooperate to the main stream suppliers, purchasing raw materials with batch bulk quantities to keep the consistent quality from the sources.
We have inspections and laboratory test in each process, milling, spraying, pilot pressing, pressing, stacking, sintering, packing, etc. All these make our products traceable, and control the quality in a stable level. The pics below are the processes for reference:
The whole process in each workshop:
Workshop: Hydraulic Press
Workshop: Sintering furnace
4. Inspection & Testing:
We have individual Laboratory for quality test and sampling and
inspection. Each batch of product has to be tested and inspected
with different gauges to confirm that reaching the
performance requirement.
5. Capacity of Stock and Delivery:
We have stable stock capacity, providing our customers with a quick delivery in cooperation with our partner carrier and freight forwarders. There are ordinary goods and finished products on shelves for customers to quickly place an order and supplement the need of their business.
