Features

Plastic thermoforming machinery is an efficient production equipment that can be used to produce disposable plastic fruit boxes, lunch boxes, and perforated dome covers. The device is equipped with a quick mold changing system and has the advantage of customized heating box design. Using positive and negative pressure thermoforming technology, plastic sheets are molded into the desired shape. This equipment has four workstations for forming, punching, cutting, and stacking, which can meet the needs of different industries and ensure product quality and consistency.

 

For high production demands or the manufacture of larger products, consider equipment with a molding area of 780 × 650 MM. A larger molding layout accommodates more cavities in the mold, significantly boosting production efficiency. To enhance stability during operation, equipment with larger forming layouts is designed with four pillars supporting each workstation, ensuring robust operational performance.

 

The Automatic plastic thermoforming machinery's operating speed can be adjusted according to customer requirements, with a maximum capability of 45 cycles per minute. However, we recommend customers operate at 20 molds per minute for PP sheets and 30 molds per minute for PET sheets to minimize the risk of machine damage caused by prolonged high-speed operation. To maintain optimal performance and extend the machine's lifespan, customers should adhere to the manufacturer's maintenance guidelines. This includes regularly replacing lubricating oil and cleaning critical components. When operating the heating box, ensure the sheet does not come into contact with the heating element during the heating process, as this can damage the element. Regular maintenance is essential to prevent damage to key machine components. Neglecting maintenance over time can result in costly repairs and reduced operational efficiency.

Recommended Products
SP-780
The Plastic Thermoforming Equipment, also known as a multi-station thermoforming machine, is designed for producing a variety of products like food containers, fruit trays, and seedling boxes. Typically, these machines come in three or four stations. Four-station thermoforming machines differ from three-station models by adding an additional punching station, ideal for items that require punching, such as fruit trays. These machines are highly versatile; for products that don’t require punching, molds can be equipped for just three stations: forming, cutting, and stacking. This flexibility makes them suitable for a range of applications, including disposable thermoforming machine needs.
SP-780E
The Less Energy Consumption Thermoforming Machine is suitable for processing different materials such as PP, PS, PET and producing various plastic products: trays, lids, vegetable boxes, flower pots, plates.
SPE-760B
The SPE-760B plastic cup machine is designed specifically for producing disposable plastic cups, bowls, plates, and other products. Its 760 × 320mm molding layout makes it suitable for manufacturing cups of various sizes. The machine is equipped with three servo motors, which are positioned to control the feeding, stretching, and lower mold movement.
