Quality control is maintained at every step, from material selection and mixing to forming, sintering, and shipping, following ISO 9001 standards. Cemented carbides are crafted at Sanalloy using state-of-the-art machining tools and sintering furnaces featuring pressurization treatment, facilitating the production of components for a wide array of industries. The increased production capacity allows for the provision of high-quality products with short lead times.

Reliability and safety are ensured through a rigorous quality inspection system, utilizing the latest analysis equipment for product inspections.

1. 1Blending

   Determine raw materials (WC powder, Co powder and other powders) by composition ratio of each grade and the weight.

   

2. 2Mixing

   Homogeneously mix and disperse various raw powders by using dispersing and mixing apparatus. Achieve activation of particle surface.

   

3. 3Pressing

   Press the mixed and dispersed powder by molds and make compacted items as cylindrical and block shapes.

   

4. 4Pre-Sintering

   Conduct heat treatment at 550~900℃ in order to obtain a strength capable of forming compacted items.

   

5. 5Forming

   Formed items will have 20% shrinkage in sintering process. Therefore, we form into the shapes according to customers’ request in anticipation of this shrinkage.

   
6. 6Sintering

   Put formed items into sintering furnace. Conduct liquid phase sintering at 1300~1500℃.

   

7. 7HIP

   Conduct heat treatment by using Argon gas as pressure-transmitting medium. Remove prove remaining inside of carbides.

   

8. 8Production Inspection

   Conduct products appearance and shape inspection, quantity confirmation.

   

9. 9Packing and Shipping

   Deliver the acceptable products to customers after packing with eco-friendly packaging materials.
