Circular Slitter Cardboard Machine Carton Round Knives For Corrugated Paper Cutting Slitter Blade
 
Production Process
◆1. Blanking---choose materials according to customer requirements.
◆2. Forging--Forging is mainly to increase the density of the material.
◆3. Annealing-to lower the temperature for processing.
◆4. Finishing-mainly processing the material into shape.
◆5. Inspection---inspect whether the product is consistent with the drawing sample.
◆6. Quenching-improve the corresponding hardness of the molded product and material.
◆7. Annealing--In order to increase the wear resistance of the product, it must be annealed for a long time.
◆8. Quenching and tempering-mainly the parallelism of quenched and tempered products to facilitate processing.
◆9. Coarse grinding-rough grinding of each surface of the product.
◆10. Precision grinding-super precision grinding, mirror grinding, improve the accuracy and parallelism of the product.
◆11. Inspection-Let unqualified products refuse to flow into the market.
◆12. Packing--different packing according to different products.
 
 

 

How Do We Make a Knife for You?

 

Raw Material — Acceptance

According to Shen Gong’s specification, we check FSSS and impurities content of raw materials for each lot.

 

Green Part — Pressing

Pressing condition is made by pressing engineer. Green density, size and appearance are strictly controlled.

 

Blank — Sintering

After 1400°C-1600°C sintering, green part turns to strong and solid alloy which is cemented carbide blank.

 

 

Blanks— Physical Properties Inspection

 

 

Finished Products— Geometry Inspection

 

 

Finished Products— Simulation Working Test
