INTRODUCTION

Rayshape’s Food Container Making Machine, a flagship product in our Plastic Thermoforming Machine lineup, is engineered to address the unique challenges of food packaging production. Combining high automation, precision forming, and hygienic design, this system delivers consistent, high-quality Plastic Food Containers while reducing operational costs. It is the ideal choice for manufacturers looking to scale production, improve product uniformity, and comply with global food safety standards.
The Plastic Thermoforming Machine is offered in three-station and four-station configurations, with the four-station model featuring an integrated punching station for seamless finishing. This design is particularly effective for high-volume production of disposable items such as cup lids, hinged food containers, and clear vegetable packaging. The machine’s advanced forming technology ensures that each container meets strict dimensional tolerances, with smooth surfaces and secure seals to prevent leakage—critical for food storage and transportation.
Material flexibility is a standout feature of our Food Container Making Machine. It processes food-grade PP, PET, and PS sheets with ease, accommodating different product requirements. PET sheets, prized for their clarity and barrier properties, are processed at speeds up to 45 molds per minute, making them ideal for retail packaging. PP sheets, known for their heat resistance and durability, are suitable for microwavable and hot-fill containers, with the machine operating at up to 30 molds per minute. The machine’s adaptive control system adjusts processing parameters based on material type and container design, ensuring optimal results every time.
Intelligent operation is at the heart of this Plastic Thermoforming Machine. The user-friendly control panel allows operators to access stored mold parameters, monitor production metrics, and adjust settings with minimal training. The parameter save function ensures that once a mold is optimized, production can be restarted quickly and accurately, reducing setup time and material waste. With its robust build, energy-saving features, and low maintenance requirements, Rayshape’s Food Container Making Machine is a reliable investment for food packaging businesses.

PRODUCTS RANGE

FEATURES AND ADVANTAGES

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

2. It integrates mechanical, pneumatic and electrical integration, and is controlled by microcomputer and programmable controller (PLC).

3. Easy-to-operate human-machine interface, and has the function of remote connection.

4. Electric lifting, double-station large-diameter unwinding, allowing a single person to load coils weighing up to 600KG.

5. Servo feeding, stepless adjustment of sheet length, high speed, accuracy and stability.

6. The upper and lower electric heating furnaces are used for four-stage heating and protection to reduce the impact of air convection on temperature, so that the product molding is stable, from 0-400 degrees in just 3 minutes, improving production efficiency. The electric heating furnace can automatically remove the device.

7. A new real-time distributed digital dynamic hot forming temperature control system is used to control the temperature of the tile at a single point, and it has automatic compensation control, with an accuracy of ±1℃. Energy saving of about 15% and extended furnace plate service life.

8. The quick mold change system can conveniently, quickly, accurately and safely change molds, reduce machine downtime, reduce labor waste, and improve production efficiency.

9. The mold opening and closing of the forming, punching and cutting stations are controlled by servo motors, with high precision, low wear, fast speed and low noise. Each station is supported by four columns, combined with a five-point structural connecting rod, which has good stability.

10. The unique vertical stacking concept ensures continuous stacking of products.

11. Automatic counting of finished product output, with production data memory function, can store 90 sets of operating data.

12. Combined with the edge material winding device, the entire production process is clean, without burrs and waste.

13. The design of the electrical cabinet is simple and refreshing, simplifying the machine assembly and wiring installation process.

PARTNER BARANDS

ESSENTIAL COMPONENT

Loading sheet part

Load automatically, lower human resource cost.

Proximity switch clever control, getting the rid of falling down of the sheet by conveying too fast.

Double stations, big diameter, reduce the frequency of changing sheet coil, improve the the production efficiency.

Max undertake roll of sheet

Weight:600kg, Diameter 800mm.

Feeding sheet part

Automatic feeding reduces human resource costs.

Actively transport the sheet and reduce the load on the conveying servo motor.

Cleverly control the proximity switch to prevent the sheet from falling too quickly during transportation.

Human-machine interface

Controlled by microcomputer and programmable controller (PLC), all action programs can be operated through the human-machine interface, simple and convenient, 15-inch touch screen.

Heater

1. Vacuum insulation cotton is installed in the heater, which has a fast reaction speed, short processing time and energy saving.

2. The furnace body is divided into two layers, the layout of the heating tiles is optimized, so that the plate is heated evenly.

Molding station

1. Mold changing auxiliary mechanism, using sliding guide rails and support rods to achieve fast mold change, saving time and effort.

2. Adopting high-power servo motor drive, high precision, high efficiency and low noise.

Molding mold

The working principle is a combination of positive and negative pressure, and some nylon plugs are used to assist stretching in the mold to make it have stronger molding ability.

There is cooling water in the mold cavity to speed up the cooling speed and make demolding easier.

Guide head structure

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

The integrated mold table (QT-600 steel) is made by a high-precision CNC milling machine. Therefore, it is wear-resistant, stable, and accurate, which prolongs the service life of the equipment.

A five-point-connecting-rod structure

This structure design provides more stable operation and faster speed.

Mold change structure

The punching hole station has the same mold changing structure as the cutting station.Greatly reduce mold change time and labor costs, improve production efficiency and safety factor, and provide convenience for your diversified product chain.

Servo motor

The station mold closing, forming auxiliary stretching, and pull-tab parts are all driven by servo motors, which have fast speed, low noise, high precision, and high efficiency.

Servo-controlled conveyor belt
