ZONESUN ZS-LK61 Automatic Thermoforming Machine for Cups, Trays & Plates
The ZONESUN ZS-LK61 is an automatic thermoforming machine for producing plates, trays, and containers from roll-fed plastic sheets. It integrates feeding, heating, vacuum forming with plug assist, cooling, trimming, and stacking in a fully automated line. Compatible with PVC, PET, PP, PS, PE, ABS, HIPS, and Acrylic, it features PLC touchscreen control for precise adjustment of temperature, vacuum, and cycle time. With a capacity of 200–300 molds/h, it is widely used for food packaging (fruit cups, salad trays, egg boxes, takeaway containers), electronics trays, pharmaceutical blister packs, and other industrial packaging applications.
Key Features
- Forming & Cutting Section – Integrates automatic heating, vacuum forming, demolding, and cutting processes to produce formed trays efficiently with reduced manual operation.
- Vacuum Forming & Plug Assist – Combines powerful vacuum suction with pneumatic plug assist to create deep-drawn products with precise contours and consistent quality.
- Vacuum Pump – Provides stable and powerful vacuum suction with a storage tank for reliable forming performance and easy maintenance.
- Ceramic Infrared Heating System – Equipped with 25 ceramic infrared heaters with individual temperature control for uniform heating and precise forming.
- Dual Water Spray Cooling System – Uses dual water spray cooling to accelerate heat dissipation, improve efficiency, and ensure stable forming of thick materials.
- Automatic Feeding & Unwinding – Automatically unwinds large-capacity plastic rolls with precise feeding control for continuous and stable material supply.
