Production / Working Process
Step 1: Cap Shell Loading – Pre-drawn cap shell fed into machine
Step 2: Cap Positioning – Precision nest aligns cap for forming
Step 3: Forming Tool Approach – Forming die advances toward cap
Step 4: Profile Forming – Tool shapes cap top and side features
Step 5: Force Dwell – Brief holding at forming position
Step 6: Tool Retraction – Forming tool withdraws from cap
Step 7: Cap Discharge – Formed cap ejected from nest
Step 8: Quality Check – Optional inline inspection station
Step 9: Next Cycle – Continuous automatic operation
Application Scenarios
• Bottle cap final profile forming
• ROPP cap shoulder and neck forming
• Tamper-evident cap band pre-forming
• Edge beading and flanging operations
• Special shape cap contour forming
Case Study
■ Customer Background
A cosmetic packaging manufacturer producing premium aluminum caps for skincare products. They needed a forming machine to create a distinctive stepped shoulder profile on their cap design for brand recognition.
■ Project Challenge
• Required complex stepped shoulder profile on 28mm diameter caps
• Sharp definition at step transition with no rounding
• Must maintain 0.03mm concentricity tolerance
• High volume production at 180 pieces per minute
■ Our Solution
• Delivered KP-FM-200 cap forming machine with servo drive
• Designed custom profile forming tooling with stepped geometry
• Configured precision nest for accurate cap centering
• Set up multi-stage forming sequence for sharp definition
■ Result & Benefits
• Step profile achieved with sharp 0.15mm transition edge
• Concentricity maintained within 0.025mm tolerance
• Stable production at 190 pieces/min
• Tooling life exceeded 4 million pieces before regrind
Frequently Asked Questions (FAQ)
Q: Can this machine handle different cap sizes?
A: Yes, by changing the forming nest and tooling, the machine can handle various cap diameters. Size changeover takes about 30–60 minutes.
Q: What types of forming operations can it perform?
A: It can perform beading, flanging, necking-in, top profiling, step forming and other contour shaping operations.
Q: Is this machine suitable for high volume production?
A: Yes, with automatic feeding and discharge, the machine runs continuously at 120–200 pieces per minute.
Q: Can it be integrated into our existing cap line?
A: Yes, the machine can be integrated between drawing and threading stations. We provide custom infeed/outfeed conveyors.
Q: What is the tolerance on formed dimensions?
A: Under normal operating conditions, formed dimension tolerance is ±0.03mm for critical features.
Q: Do you offer custom tooling development?
A: Yes, we design and manufacture custom forming tooling based on your cap drawings.
