Pressing
CNC automatic pressing machines form the powder into insert blanks with consistent density and dimensional accuracy.
Sintering
Vacuum sintering at 1400-1500°C followed by HIP (Hot Isostatic Pressing) for maximum density and strength.
Grinding
Precision grinding on CNC machines to achieve tight dimensional tolerances and superior surface finish.
Edge Sharpening
Precision edge sharpening to create the cutting geometry required for optimal machining performance.
Passivation
Edge passivation treatment to improve tool life and prevent chipping during high-speed cutting operations.
Coating
PVD/CVD coating application in various colors (bronze, gold, black, nano blue, etc.) for enhanced wear resistance.

What is the weight of DNMG150616-PR?
How much does a carton of DNMG150616-PR weigh for shipping?
How to calculate shipping weight for DNMG150616-PR bulk orders?
Example for 5,000 pieces:
- Net weight: (14g + 1g) × 5,000 = 75kg
- Cartons: 3 cartons (2,000 + 2,000 + 1,000)
- Carton box weight: 3 × 1kg = 3kg
- Total shipping weight: 78kg
Adjust the formula by replacing 5,000 with your desired quantity. We recommend using this formula to estimate logistics costs before placing an order.
