High Pressure Grinding Roll (HPGR) is mostly used to produce aggregate in the construction industry or refine varied minerals like iron ore, gold, and copper in the mining industry. HPGR processes materials by crushing and compressing the feed with two parallel rollers. Compared to other comminution technologies, the HPGR is a proven mature crushing technology to reduce costs and improve productivity. Among all the components of an HPGR, carbide wear studs and edge plates play a vital role in determining the lifetime of HPGR.

Oston Carbide manufactures premium and consistent quality tungsten carbide studs and edge plates for HPGR. The well-selected powder and rigorous manufacturing process ensure the high quality of our HPGR studs and edge plates. Full isostatic supressing and HIP sintering furnaces guarantee the average density to consistently manufacture wear components with outperformed quality and reliability.

1. Material Milling and Desiccation
Dust-Free Workshop: All staff must wear specified uniforms before entering the workshop.

2. TPA suppressing and HIP sintering 
Machinery Automation:Automatic manipulators are installed for all of our TPA suppressing facilites,which is more accurate on weight controlling and reduces production cost.
Strict rules of operation: All operation need be conducted strictly as process rules.

3. Quality checking of trial production.
New testing piece: Testing piece must be produced before a new batch of material is used for mass production to ensure the stable quality.

4.Grinding and Machining
We own all facilitess for the whole carbide machining system to ensure the delivery in time,including surface grinding lathe,external grinding lathe,centerless grinding lathe,wire cutting machine,EDM sparkling machine.

5.quality checking of finished products and package.
Double Quality Checking: Inspection for semi-finished and finished products are both essential,products with defects will never be shipped.
Safe package and delivery: Kraft paper for the first layer,bubble plastic for the second layer,gaps are filled with sponge,We focus on every package detail to ensure that clients receive our goods with good looks and good quality.
