FAQ for tungsten carbide preforms:<\/strong><\/h5>\n
Q1: What is a tungsten carbide preform? What is near-net-shape?<\/strong><\/h6>\n

A: Tungsten carbide preform is semi-finished carbide blank pre-machined with complex profiles (steps, tapers, coolant holes, special contours) at pressed compact stage before sintering. Near-net-shape means the sintered part is extremely close to final dimension, drastically reducing post-sinter grinding & wire EDM cost.<\/p>\n

 <\/p>\n

Q2: What grades of tungsten carbide preforms do you offer?<\/strong><\/h6>\n

A: We supply full series cemented carbide grades: BU06, BU09, YG10X, BT15, BT20, BT25UF, YG6, YG8, YG10, YG13, YG15, YG20, YN5, YN6, YN8, YN10, YN14,YN15,YN20, ultrafine\/submicron grain carbide, as well as equivalent ISO grades WC-Co, WC-Ni alloy for corrosion resistance. Grades can be customized based on customer\u2019s working conditions (cutting, stamping, mining, wear parts).<\/p>\n

 <\/p>\n

Q3: Can you make non-cobalt tungsten carbide preforms?<\/strong><\/h6>\n

A: Yes. We produce WC-Ni, WC-Ni-Cr preforms for corrosive working environment where cobalt leaching is forbidden.<\/p>\n

 <\/p>\n

Q4: Can you make preforms with internal coolant holes?<\/strong><\/h6>\n

A: Yes. We pre-drill straight \/spiral coolant holes on green preforms, holes keep intact after sintering without secondary drilling, greatly save processing cost for drill & end mill manufacturers.<\/p>\n

 <\/p>\n

Q5: Can you make preforms with internal coolant holes?<\/strong><\/h6>\n

A: Yes. We pre-drill straight \/spiral coolant holes on green preforms, holes keep intact after sintering without secondary drilling, greatly save processing cost for drill & end mill manufacturers.<\/p>\n

 <\/p>\n

Q6: What complex shapes can your carbide preforms support?<\/strong><\/h6>\n

A: Step shafts, T-shape blanks, special nozzles, gear preforms, micro drill blanks, eccentric parts, grooved preforms, custom irregular profiles according to customer’s drawings.<\/p>\n

 <\/p>\n

Q7: What is the standard dimensional tolerance of sintered carbide preforms?<\/strong><\/h6>\n

A: Standard tolerance: \u00b10.1mm for general preforms. Tighter tolerance \u00b10.03~\u00b10.05mm is available for precision series with extra HIP treatment. All preforms allow small finish grinding to reach final drawing tolerance.<\/p>\n

 <\/p>\n

Q8: What is your lead time?<\/strong><\/h6>\n

A: In-stock items can be shipped within 2\u20133 days. New non-standard customized orders take 7\u201315 working days, subject to processing complexity.<\/p>\n

 <\/p>\n

<\/div>\n
Q9: What is your MOQ for custom carbide preforms?<\/strong><\/h6>\n

A: Small trial order MOQ: 1 piece for new development.<\/p>\n
