Production and test of tungsten carbide cross big bit tips for drilling stainless steel hard material
1, After the order is confirmed,TC carbide cross tips will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of the samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production
3, Bulk production ,press the raw materials to shape blanks,and all
TC carbide cross tips must be passed by semi finished inspection.
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have 10 sets of vacuum sintering furnace and 2 sets
of HIP in the factory ensure the best quality and production
capacity.
Packing and delivery of Good impacting carbide cross big bit tips for drilling concrete and steel
step 1, wrapped TC carbide cross tips in paper to avoid TC carbide
cross tips to broke
step 2, put the TC carbide cross tips in inner small carton box
step 3, put the inner box into outter carton and fill the carton
with foamed plastic
step 4, wrap the carton with packaging tape
step 5, you can choose any delivery way such as DHL,TNT,UPS ect.
