Contact Heating Thermoforming Machine

Sunwell Global’s Contact Heating Thermoforming Machine is specifically designed for the production of thin-gauge, shallow-draw BOPS packaging products. By utilizing direct contact heating technology instead of a conventional heating oven, this system delivers excellent forming accuracy, reduced energy consumption, and enhanced production safety.

Direct Contact Heating Technology

The SF1100 model heats the plastic sheet directly through a contact heating platen, eliminating the need for a traditional heating oven. This design significantly reduces energy consumption and floor space, while preventing sheet sagging during heating and minimizing fire risks.

Wide Material Compatibility
Capable of processing BOPS, HIPS, and PET, the machine produces a wide range of thin-gauge food containers with consistent forming quality and excellent surface finish.

Servo-Driven Precision Forming System
The top moving platen is servo motor driven and connected to a mechanical toggle system, providing precise motion control, accurate positioning, and stable forming pressure for repeatable, high-quality results.

Multi-Layer Heating and Forming Platen Design
The fixed bottom platen features a four-layer structure:

• Surface plate with thousands of micro air holes for uniform pressure forming
• Airflow channel plate for controlled forming air distribution
• Integrated aluminum cast-in heaters with multi-zone temperature control
• Thermal insulation plate to improve energy efficiency

This structure ensures uniform heating, precise air control, and stable forming performance.

Enhanced Safety and Process Control
Multiple heating and forming zones are matched to different mold sizes. The forming area is fully protected by safety guards and light curtains, while individual air on/off control valves allow fine-tuned forming precision.

Flexible Sheet Transfer and Cutting Options
The formed sheet is indexed by a reciprocating timing belt system for accurate length control. The system can be configured with:

• A cross flying cutter and stacker for off-line secondary cutting
• Edge marking punchers for easy quantity identification
• In-line vertical trim press for high-speed, mass production
