INTRODUCTION

RS-750-800-3 Positive and Negative Pressure Multi-Station Plastic Thermoforming Machine adopts internationally advanced plastic sheet forming technology. It is a plastic sheet forming machine with an integrated mechanical, pneumatic and electrical design. It can automatically complete a full range of processes including loading, feeding, heating, forming, punching, cutting, stacking, finished product conveying and edge material winding.

It is suitable for processing various materials such as A-PET, R-PET, C-PET, BOPS, HIPS, PP, PLA, PVC and barrier materials. It can produce high-transparency, high-stretch, shallow-stretch, round, square, vertical two-way stretch and flanged products, such as trays, lids, fruit and vegetable boxes, flower pots, shells, seedling trays and plates.

It can manufacture products that cannot be produced by single-station thermoforming machines, such as PLA products, perforated plastic lids or containers, and integrated packaging containers with connected body and lid (e.g. fruit boxes, egg trays).

FEATURES AND ADVANTAGES

1.High degree of standardization, complete functions, safe, efficient, energy-saving and hygienic.

2.It features mechanical, pneumatic and electrical integration, controlled by a microcomputer and programmable logic controller (PLC).

3.Easy-to-operate human-machine interface with remote connection function.

4.Electric lifting and double-station large-diameter unwinding allow a single operator to load coils up to 600KG.

5.Servo-driven feeding with stepless adjustment of sheet length, ensuring high speed, precision and stability.

6.Upper and lower electric heating furnaces adopt four-stage heating and protection to minimize the impact of air convection on temperature, ensuring stable product molding. It heats from 0 to 400°C in only 3 minutes, greatly improving production efficiency. The electric heating furnaces are equipped with an automatic removal device.

7.A new real-time distributed digital dynamic thermoforming temperature control system is adopted for single-point heating plate temperature control, with automatic compensation control and an accuracy of ±1℃. It saves about 15% energy and extends the service life of the heating plates.

8.The quick mold change system enables convenient, fast, accurate and safe mold changing, reduces machine downtime and labor costs, and improves production efficiency.

9.Mold opening and closing for the forming, punching and cutting stations are driven by servo motors, featuring high precision, low wear, high speed and low noise. Each station is supported by four columns and a five-point structural connecting rod for excellent stability.

10.The unique vertical stacking design ensures continuous and stable product stacking.

11.Automatic finished product counting with production data memory function, capable of storing 90 sets of operating data.

12.Equipped with an edge material winding device, the whole production process is clean, free of burrs and waste.

13.The electrical cabinet features a simple and neat design, simplifying machine assembly and wiring installation.

PARTNER BARANDS

ESSENTIAL COMPONENT

Loading sheet part

Automatic loading, lower labor cost.

Smart control via proximity switch, prevents sheet from falling due to excessive conveying speed.

Double stations, large diameter, reduce coil changing frequency and improve production efficiency.

Max sheet coil capacity

Weight: 600 kg, Diameter: 800 mm

Feeding sheet part

Automatic feeding reduces labor costs.

Active sheet transportation reduces the load on the conveying servo motor.

Smart control via proximity switch prevents sheet from falling due to excessive conveying speed.

Human-machine interface

Controlled by a microcomputer and programmable logic controller (PLC), all operating programs can be controlled via the human-machine interface (HMI). Simple and convenient operation with a 15-inch touch screen.

Heater

1.The heater is equipped with vacuum insulation cotton, featuring fast response, short processing time and energy efficiency.

2.The furnace body adopts a double-layer structure with optimized heating tile layout, ensuring uniform heating of the plate.

Molding station

1.Equipped with mold changing auxiliary mechanism, sliding guide rails and support rods enable fast mold change, saving time and labor.

2.Driven by high-power servo motor, featuring high precision, high efficiency and low noise.

Molding mold

Working principle: adopts a combination of positive and negative pressure, with nylon plugs assisting stretching inside the mold to enhance forming capability.

The mold cavity is equipped with cooling water to accelerate cooling and facilitate demolding.

Guide head structure

The workstation is supported by four columns (45# steel, hard chrome-plated).

The integrated mold table (QT600 ductile iron) is manufactured using high-precision CNC milling, making it wear-resistant, stable and accurate, thus extending the service life of the equipment.

A five-point-connecting-rod structure

This structural design ensures more stable operation and higher speed.

Mold change structure

The punching station adopts the same mold changing structure as the cutting station.

This greatly reduces mold change time and labor costs, improves production efficiency and safety factor, and facilitates your diversified product chain.

Servo motor

Servo motors are adopted to drive mold closing, auxiliary forming stretching and pull-tab operations, featuring high speed, low noise, high precision and high efficiency.

Servo-controlled conveyor belt

Set conveyor belt parameters directly on the operation screen.

Freely adjust and control conveying length and speed.

Rewinding waste of edge sheet

Our multi-station thermoforming machines are equipped with a torque motor-driven winding unit, which effectively collects leftover materials into rolls. The unit features a retractable shaft for easy removal upon completion of production.

This advanced waste handling system enhances operational efficiency and cleanliness, making the multi-station thermoforming machines ideal for high-quality, sustainable production.
