Machine Features

		1. Unwinding Unit The machine uses a double mechanical shaft unwinding system combined with a chain-type automatic lifting device, making manual loading and roll changing easier and more efficient.

2. Web Guiding Station Three sets of guide rollers with buckle positioning keep the material aligned, correcting deviation and ensuring stable material feeding throughout production.

		3. Silicone Oil Coating Unit Silicone oil is sprayed onto the material during operation to improve release performance and facilitate smooth demolding after forming.

4. Material Feeding & Chain Clamping Unit The material is clamped by positioning chains and rollers to prevent shrinkage during heating and forming. The guide rail width is electrically adjustable, and the system supports synchronous or independent front–rear movement for flexible operation.

		5. Heating Oven Electric heating with multi-zone temperature control heats the material quickly and evenly, reaching up to 300°C within about 10 minutes.

6. Upper Mold Press Plate The upper mold press plate is cylinder-driven and works together with the lower mold to form a sealed cavity for efficient thermoforming.

		7. Lower Mold System A universal base plate design allows quick mold replacement, enabling fast switching between different product types.

8. Sealing Assistance Device A movable pressure plate presses down during forming to enhance sealing and prevent air leakage, ensuring stable forming quality.

		9. Cooling & Forming Station Dual cooling methods ensure rapid shaping: Air cooling: Four fans on each side provide strong airflow cooling. Water cooling: Ten cold-water spray guns apply adjustable mist cooling to accelerate product setting.

10. Product Collection Rack Finished products fall onto the lower receiving platform for stacking and collection, improving production efficiency.
