RM-3 Three-station Thermoforming Machine

Short Description:

The three-station positive and negative pressure thermoforming machine is an efficient and automatic production machine to produce disposable trays, lids, lunch boxes, folding boxes and other products. This thermoforming machine has three stations, which are forming, cutting and palletizing. When forming, the plastic sheet is first heated to a temperature that makes it soft and malleable. Then, through the shape of the mold and the action of positive and negative pressure, the plastic material is formed into the desired product shape. Then the cutting station can accurately cut the formed plastic products according to the shape of the mold and the size of the product. The cutting process is automated to ensure cutting accuracy and consistency. Finally, there is the stacking and palletizing process. The cut plastic products need to be stacked and palletized according to certain rules and patterns. The three-station positive and negative pressure thermoforming machine can improve production efficiency and product quality through precise control of heating parameters and pressure, as well as equipped with cutting and automatic palletizing systems, to meet the market’s demand for disposable plastic products, and also bring convenience and benefits.

Application Area

The 3-station thermoforming machine is suitable for food packaging, catering industry and other fields, providing convenience and comfort for people's life.



Equipment Preparation:
Ensure the 3-station thermoforming machine is securely connected and powered on, with all safety measures in place to avoid any mishaps during operation.
Conduct a thorough inspection of the heating system, cooling system, pressure system, and other functions to verify that they are functioning normally and ready for production.
Carefully install the required molds, double-checking to ensure that they are securely fastened in place, minimizing the risk of misalignment or accidents during the molding process.

Raw Material Preparation:
Begin the process by preparing a suitable plastic sheet for molding, ensuring it meets the necessary size and thickness specifications required by the molds.
Select high-quality plastic materials that will provide optimal results during the thermoforming process, enhancing the efficiency and overall quality of the final products.

Heat Settings:
Access the control panel of the thermoforming machine and set the heating temperature and time appropriately, taking into consideration the specific plastic material being used and the mold requirements.
Allow the thermoforming machine sufficient time to reach the designated temperature, guaranteeing that the plastic sheet becomes pliable and ready for molding.

Forming - Cutting - Stacking and Palletizing:
Gently place the preheated plastic sheet onto the mold surface, ensuring it is perfectly aligned and free from any wrinkles or distortions that could compromise the forming process.
Initiate the molding process, carefully applying pressure and heat within the specified time frame to shape the plastic sheet precisely into the desired form.
Once the forming is complete, the newly shaped plastic product is left to solidify and cool within the mold, before proceeding to cut, and orderly stacking for convenient palletizing.

Take Out the Finished Product:
Inspect each finished product meticulously to ensure it conforms to the required shape and adheres to the established quality standards, making any necessary adjustments or rejections as needed.

Cleaning and Maintenance:
Upon completion of the manufacturing process, power down the thermoforming machine and disconnect it from the power source to conserve energy and maintain safety.
Thoroughly clean the molds and equipment to eliminate any residual plastic or debris, preserving the molds' longevity and preventing potential defects in future products.
Implement a regular maintenance schedule to inspect and service various equipment components, guaranteeing that the thermoforming machine remains in optimal working condition, promoting efficiency and longevity for continuous production.
