Precision is key in egg tray manufacturing, and the Multi Station Thermoforming Machine from Wenzhou Rayshape Machinery Co., Ltd. delivers it perfectly. As a subsidiary of Elemotion Group, we are located in the coastal Binhai New Area of Wenzhou. Our Multi Station Thermoforming Machine is engineered for high-volume, low-consumption production, ensuring a reliable and stable output.

This equipment is essential for producing egg trays, meal boxes, and fruit containers using materials like PET, PS, PVC, and eco-friendly PLA. We offer versatile plate sizes like 730 * 800 to maximize production capacity by increasing the number of mold cavities. The machine can reach speeds of 45 molds per minute for PET sheets, providing the high-speed performance required for industrial orders. A defining feature of the Rayshape Plastic Thermoforming Machine is our future-oriented control system. It incorporates a parameter save function that allows engineers to save optimized settings permanently.

This simplifies operation and reduces labor costs, as subsequent runs are ready with a single click. Rayshape carries forward the Elemotion spirit of diligence and continuous improvement. We provide a seasoned R&D team and strong operational support from our headquarters at No. 19 East Section of Pinghai Avenue. We are dedicated to self-surpassing excellence and becoming a leading enterprise in the global plastic packaging industry. Trust Rayshape for precision and efficiency in your egg tray production line.

Advantages Of Plastic Thermoforming Machines

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

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 thermoformers feature a winding unit with torque motor to efficiently collect the offcuts and wind them into a roll with one side retractable, which can be conveniently removed at the end of production.

This advanced waste management system improves operating efficiency and cleanliness, making multi-station thermoformers ideal for high-quality and sustainable production.
