1. Stamping Workshop
The blade part will be stamping by punching machine according to the specification detailed.
2. Heat Treatment Workshop
Straighten blade then put them into a heat treatment furnace by heating at a high temperature for a long time to sufficiently diffuse internal chemical components. for vacuum nitriding heat treatment of 1050℃-1100℃, followed by low temperature nitriding treatment and performing 200℃-300℃. Because tempering treatment allows the molecules to be aligned and enhance the toughness of the blade.
3. Molding Workshop
Polishing the knife handle on the accurate position after general grinding, then pulling the blade back and chamfer. Handle body is general polishing with NO.180 sand belt wheel, then using NO.240 belt wheel to be carefully polishing. The handle process is basically completed after re-polishing by using NO.240 sand belt wheel.
4. Welding Workshop
The handle first is fixed on both sides on the welding machine ,after the position is confirmed and then performed by argon arc to be automatically welded, and welding blade with the knife handle so the initial handle model of knife comes out.
5. Blade Wet burnishing Workshop
Carry out the CNC single/double-side oblique grinding of the blade according to the angle of a blade and the data detail and exchange into rubber wheel to burnish the surface. During the process the blade was covered by a film to prevent the blade from being scratched.
6. Polishing Workshop
Manually polish the handle after finishing fixing & strengthening the shape of the casting mold of the wood or plastic through using steel nails.To begin with, polishing the welding part then to the bolster part then polishing the knife handle on the accurate position after general grinding. Pulling the blade back and chamfer. Handle body is general polishing with NO.180 sand belt wheel, then using NO.240 belt wheel to be carefully polishing. The handle process is basically completed after re-polishing by using NO.240 sand belt wheel.
7. Sharpening Blade Edge Workshop
The next step is to carry out the wet opening blade treatment of the water grinding disc, then use the wool wheel to pull the sharp edge, remove the surface rags.
8. Cleaning Workshop
After finishing all these processes, the knives will be carried to print customized LOGO. Next, we will put the knife into the ultrasonic automatic cleaning machine to ultrasonic cleaning and drying them.
9. Packing Workshop
Put the products on the plastic bag, paper sleeve, color box, outer box, that all the stainless steel knives are finished.
