Product Description
Tungsten carbide(also named as cemented carbide) a kind of material made from combination of tungsten and carbon(with formula WC) with cobalt binder,it could keep stable property under high temperature 800ºC with high compressive strength,high hardness and strong resistance to wear,which make tungsten carbide cutting tools a perfect choice for many industrial needs.
Tungsten carbide rod is the preferred material for metal cutting tool manufacturing, widely used in the industries which has high requirements for wear-resistance, corrosion-resistance and high-temperature resistance. It has a lot of outstanding performance.

1. Material Milling and Desiccation
Dust-Free Workshop: All staff must wear specified uniforms before entering the workshop.
2. Isostatic Suppressing for carbide rods
Machinery Automation:Automatic manipulators are installed for all of our TPA suppressing facilites,which is more accurate on weight controlling and reduces production cost.
3. HIP Sintering
Strict rules of operation: All operation need be conducted strictly as process rules.
4. 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.
5. 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.
6. quality checking of finished products.
Double Quality Checking: Inspection for semi-finished and finished products are both essential,products with defects will never be shipped.
7. Packing and delivery
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.
Cemented carbide rods are widely used for high-quality solid carbide tools such as milling cutters, end mills, burs,drills,micro drills or reamers.in addition,tungsten carbide rods are also used as punching rods in die and mold field,as process parts in automobiles and aircraft industry.
