Carbide die core blank (Heading die core, forging die core or other die core) is the raw material for carbide die factories to make finished heading die or forging die, ground carbide die core will be assembled into tool steel covers, to get a finished die.
Because of the very high hardness and toughness, the stable chemical and physical characters under low temperature and high temperature, the very good anti-corrosion character, tungsten carbide is widely applied as the die blank material in automotive, aerospace, energy, firearms, medical, construction, agriculture and heavy industrial.
Carbide die blank is the carbide blank which as sintered or surface coarse ground, die factories do further precise machining as per their drawings, then assemble with some other parts or dies to get the final finished dies.
Carbide die core blank ( also mentioned as carbide die nib, including heading die core blank, forging die core blank, powder metallurgy die core blank or other die core blank) is the raw material for carbide die factories to make finished heading die, forging die, powder metallurgy die or other dies, precise ground carbide die core will be assembled into tool steel covers, to get a finished die.

1. Best raw material: Origin new tungsten carbide powder from the best powder factory of China Gesac are applied to production.
2. Production capability: Betalent carbide has production facilities of 20tons per month heading die production capability. Can meet the quantity requirement of most middle scale factory requirements of carbide heading die core blank.
3. Technology capability: Can produce carbide die cores of which outer diameter within 300mm, and hole diameter bigger than 1mm, length within 200mm, for some complicated limit size combination please check case by case.
4. R&D capability: Betalent carbide has many popular carbide grades for customer’s options of heading die material, and some special grades are available for some special applications, to some application customer need and beyond Betalent’s grades list, Betalent has the capability to set a new project to develop one new grade for the customer. A fixed professional technical team in mold design and manufacturing can work with customers to solve the problems during mold production and offer materials solutions.
5. Strict quality inspection: Carbon sulfur analyzer, Hardness tester, TRS tester, Coercive force tester, microstructure checking microscope, cobalt magnetic tester, Rockwell hardness tester, and Vickers hardness tester are applied to detect the material flaw if any and make sure the heading die blank material is qualified. The last material checking item is scanning the whole carbide die blank by ultrasonic instrument, which can find out the material flaw special the sand hole easily.
6. Size control: Accurate size control enables a low size tolerance, which reduces machining allowance.
7. Grinding service: Outer diameter surface, inner hole, and the end surface of carbide die blank can be skimmed ground or fine ground according to drawing.
8. Delivery time: Simple items(Outer diameter less than 30mm, height less than 100 and hole diameter bigger than 2mm) can be delivered in three days, if simple grinding is needed, the delivery time is one week. For the delivery time of special or complicated items please consult a professional salesperson.
