Production / Working Process
Step 1: Material Feeding – Coil or strip material fed by feeder
Step 2: Material Positioning – Precision guide aligns material under die
Step 3: Ram Descent – Punch ram descends with die assembly
Step 4: Blanking / Forming – Die performs cutting or forming operation
Step 5: Pressure Holding – Brief dwell at bottom of stroke
Step 6: Ram Return – Punch ram returns to top position
Step 7: Part Ejection – Formed part ejected from die
Step 8: Material Advance – Feeder indexes material for next cycle
Step 9: Repeat Cycle – Continuous automatic operation
Application Scenarios
• Bottle cap blanking and preliminary forming
• Metal lid and end stamping operations
• Progressive die multi-station forming
• Deep drawing pre-blanking operations
• Secondary operations: piercing, embossing, trimming
Case Study
■ Customer Background
A cap manufacturing plant in Southeast Asia expanding production capacity. They needed additional stamping presses to feed their growing cap production lines, replacing older manual presses with higher precision automated machines.
■ Project Challenge
• Needed 63-ton presses compatible with existing progressive dies
• Required higher stroke rate to increase output
• Had to integrate with existing coil feeding systems
• Limited skilled maintenance staff available
■ Our Solution
• Supplied 3 units of KP-PM-63 C-frame stamping machines
• Configured 200 SPM high-speed operation mode
• Designed adapter plates to fit existing die sets
• Equipped automatic lubrication and fault diagnosis system
■ Result & Benefits
• Stroke rate increased by 40% compared to old presses
• Existing dies installed and running within 2 days
• Maintenance frequency reduced by 60%
• Operator training completed in one day per machine
Frequently Asked Questions (FAQ)
Q: How do I select the right tonnage stamping machine?
A: Required tonnage depends on material thickness, shear strength and cutting perimeter. Our engineers can help calculate exact requirement based on your product specifications.
Q: What is the difference between C-frame and H-frame press?
A: C-frame has open front design for easy die access. H-frame (straight side) provides better rigidity and alignment precision for high precision and large tonnage applications.
Q: Can your stamping machine use our existing dies?
A: Yes, as long as die dimensions fit within bed size and shut height range. We can also adapt the press with custom bolster plate if needed.
Q: What safety features are included?
A: Standard safety features include light curtain guards, interlocked safety doors, emergency stop buttons, overload protection and dual-hand control.
Q: What is the expected service life of the machine?
A: With proper maintenance and operation within rated parameters, service life exceeds 15–20 years. Key components are designed for decades of continuous operation.
Q: Do you provide installation and training?
A: Yes, we provide professional installation, commissioning and operator training at your facility.
