Machine Catalog: Individual Unit Breakdown
1. Metal Pressing & Cap Stamping Machine
Primary Function: Converts raw aluminum or tinplate sheets into preliminary cap blanks or shallow shells with maximum material utilization.
Engineering Advantage: Built with a stress-relieved high-rigidity frame and high-tonnage pneumatic clutch. Eliminates sheet slippage and delivers up to 300 strokes per minute with uniform clamping force.
2. Bottle Cap Deep Drawing Machine
Primary Function: Executes multi-pass deep drawing for long-skirt aluminum closures (e.g., 30x60mm wine capsules) without sidewall thinning or wrinkling.
Engineering Advantage: Features servo-controlled hydraulic cushion pressure management, ensuring mirror-smooth cylinder walls and zero micro-fractures in decorative lacquers.
3. Bottle Cap Forming Machine
Primary Function: Performs precision top rim shaping, flanging, and pre-skirt curling for various closure profiles.
Engineering Advantage: High-precision rotary indexing star-wheel ensures 100% concentricity during high-speed rotation, preventing cap ovality defects.
4. Bottle Cap Thread Rolling Machine
Primary Function: Rolls crisp, deep, and leak-proof internal or external threads onto metal cap skirts.
Engineering Advantage: Equipped with hardened alloy steel thread rollers driven by independent servo motors. Achieves thread profile tolerances within ±0.02 mm for zero-leakage bottle sealing.
5. Cap Knurling Machine
Primary Function: Imprints side-wall anti-slip vertical ribs/knurls for ergonomic finger grip during opening.
Engineering Advantage: Adjustable radial pressure dials allow instant depth tuning across different aluminum hardness grades without damaging outer print coatings.
6. Cap Embossing Machine
Primary Function: Stamps crisp 3D raised logos, brand names, or decorative patterns onto the top flat surface of the metal cap.
Engineering Advantage: Tooling dies are CNC-ground from ultra-hard alloy steel, ensuring sharp logo definition even after millions of high-impact impressions.
7. Bottle Cap Cutting Machine (Tamper-Evident Slitting)
Primary Function: Executes horizontal scoring and bridge perforation for tamper-evident security rings (ROPP style).
Engineering Advantage: Micro-adjustable blade depth controls maintain bridge thickness consistency within ±0.015 mm, guaranteeing clean breakage upon consumer opening.
8. Cap Liner Inserting Machine (Wadding Unit)
Primary Function: Cuts and inserts sealing discs (EPE foam, PE, Saranex, or tin-foil liners) into cap interiors at high speeds.
Engineering Advantage: Vacuum-assisted disk positioning coupled with mechanical insertion probes ensures flat placement with zero liner tilt or adhesive contamination.
