Upper die：Made of high-quality spring steel, it is not easy to deform and has sufficient toughness.
Lower die: 40Cr is an excellent alloy structural steel. Its heat treatment process is determined by performance. The following are the heat treatment methods:
1 Quenching: Heating temperature: about 850℃ (oil cooling), to ensure that austenite is fully homogenized.
2 Tempering: 200~300℃ low temperature tempering: Features: high hardness


Please note ！！！ that the material thickness needs to meet the design limitations and should not be too high or too low.
1. The max thickness of iron plate: 1/10" to 2/5" (3-10 mm)
2. the max thickness of copper: 1/10" to 1/2" (3-12.7 mm)
3. the max thickness of aluminum bar: 1/10" to 1/2" (3-12.7 mm)
4. the max thickness of stainless steel: 1/10" to 3/10" (3-8 mm)

warring！！！Materials thinner than 3mm are not suitable for use with this die.
