Good quality carbide products rely on 100% virgin raw materials and advanced wet-milling, pressing machines and sintering furnaces. We put emphasize on every production process of our carbide blanks. To keep good quality of carbide blanks is the base of furtherly machined high precision finished carbide parts.
In order to ensure the quality of all our tungsten carbide finished products, a very strict QC management system we called “Quality Control Center” has been introduced. With our advanced inspection equipment and our professional inspectors, we are able to do raw materials inspection, on-site inspection and after finishing inspection to ensure 100% good quality of your carbide products.
We own a series of high-precision grind machines, including flat grinding machines, OD and ID machines, Centerless grinding machines and customized grinders. Also we have CNC machines, EDM, Wire-cutting machines and drilling machines etc. With our skilled workers, we can control very high precision of each carbide part.
Special-designed packing boxes and tubes will be used properly for the standard and customized carbide products to ensure the safety of the goods during the transportation process. A wide range of shipping ways can be available for your shipments, for example we can ship goods by Sea, by air and by Express companies like DHL/FedEx/UPS/TNT etc.
Carbide rods are suitable for the processing of general steel, cast iron, stainless steel, heat resistant steel, nickel base, and titanium alloy. They are widely recommended for twist drills, end mills, taps, and gun drills.
The tungsten solid carbide rods are press molded through molding or extrusion, and then sintered utilizing a low-pressure sintering integrated furnace to ensure high overall performance.
Ground long rods and cut-to-length rods generally feature diameter tolerances of h5 or h6, or can be processed according to specific customer requirements such as -0.005. End chamfers are also available.
APEX operates a strict QC management system known as the "Quality Control Center", conducting raw materials inspection, on-site inspection, and post-finishing inspection with advanced testing equipment.
Goods are securely protected in special-designed packing boxes and tubes. Shipping options include Sea freight, Air freight, and express courier services such as DHL, FedEx, UPS, and TNT.
