Automatic Plastic Lid Cover Forming Machine: Fast, Precise Mass Production for Packaging

In food, daily chemical, and pharmaceutical packaging, plastic lids (beverage caps, sauce jar lids, reagent stoppers) are in huge demand. Traditional machines struggle with slow speed, poor precision, and heavy manual work—issues solved by the Automatic Plastic Lid Cover Forming Machine. It works with PP, PE, PET, and turns raw materials into finished lids fully automatically, cutting costs and boosting efficiency.

Core Advantages: Fast, Accurate, Stable

1. Full Automation – 3X Higher Output

Integrates "feeding → heating → forming → cooling → demolding → sorting → waste recycling"—no manual intervention:

Speed: 6,000–12,000 pcs/h (100–200 pcs/min) for 38mm beverage caps (3X faster than semi-automatic models), meeting 100,000+ daily orders.

24/7 Operation: 98% stability rate with servo-PLC control; only 1 person needed to monitor, slashing labor costs.

2. High Precision – Perfect Lid Quality

Accurate Forming: Custom molds (15–100mm diameters: threaded, flip, anti-theft lids) with ≤±0.05mm positioning error. Uniform thickness (≤0.1mm deviation) and no burrs.

Reliable Sealing: Optimized cooling (0.5–2s adjustable) ensures clear threads and tight gasket fit. 99.9% pass rate in airtightness tests (no leakage).

Material Compatibility: Adjusts heat (180–250℃) and pressure (0.8–1.5MPa) for PP/PE/PET, ensuring lid toughness/heat resistance.

3. Smart & Low-Cost

Easy Operation: 10-inch touchscreen with 20+ preset templates; beginners master it in 1 hour. Real-time alerts for faults (e.g., mold blockage) cut downtime to ≤20 mins.

Energy & Material Saving: Waste rate ≤3% (recyclable scraps); 20% lower energy use vs. traditional machines, saving $15–30 daily on electricity.

4. Safe Design

Meets GB 5226.1 standards: enclosed chamber (no molten plastic splashes, ≤75dB noise), emergency stop, infrared safety curtains, and heat shields (surface ≤50℃ to avoid burns).

Applications

Widely used for:

Food/drinks: Mineral water caps, cola caps.

Daily chemicals: Shampoo flip lids, detergent caps.

Pharmaceuticals: Reagent stoppers (optional sterile chamber for GMP compliance).
