A used three-station positive/negative pressure thermoforming machine with 910×710 mm forming area, suitable for food containers, fruit boxes, egg trays, plates, biscuit boxes and seedling trays.
A used three-station positive/negative pressure thermoforming machine is not only a single machine purchase. For buyers producing disposable food containers, fruit boxes, egg trays, plates, biscuit boxes or seedling trays, the real project is a complete thermoforming production line: sheet material, heating, forming, punching or cutting, stacking, auxiliary equipment and final product checking.
This used machine has a 910×710 mm forming area and is designed for PP, PS, PET, PLA and PVC sheet. The provided material shows the main machine, technical parameters, production process, suitable finished products and auxiliary equipment required for a complete thermoforming workflow.
Confirmed Machine Parameters
Based on the provided parameter image, this used three-station positive/negative pressure thermoforming machine includes the following confirmed details:
- Machine type: used three-station positive/negative pressure thermoforming machine
- Forming area: 910×710 mm
- Suitable materials: PP, PS, PET, PLA, PVC
- Sheet thickness: 0.2-2.0 mm
- Control system: Delta PLC and Delta control screen
- Upper mold: 4.5 kW
- Lower mold: 4.5 kW
- Upper punching: 5.5 kW
- Lower punching: 5.5 kW
- Sheet pulling: 4.5 kW
- Stacker lowering servo: 2 kW
- Power supply: 380V / 50Hz, three-phase
- Working efficiency: 5-15 molds/min, depending on material thickness
- Year: 2021
- Servo brand: Delta
These parameters should be checked together with the buyer's product size, material, sheet width, forming depth, mold layout and output target before quotation.
Complete Thermoforming Process
The process image shows a practical production route:
- Granular raw material
- Sheet extruder
- Sheet roller
- Thermoforming machine
- Heating
- Forming
- Punching or cutting
- Stacking
- Finished product
This is why a used thermoforming project should not be evaluated only by the forming machine price. The buyer must confirm whether the sheet extrusion line, mold, chiller, vacuum pump, air compressor, refrigerated dryer and other supporting equipment are also required.
Suitable Finished Products
According to the product application image, this machine direction can be used for many disposable packaging products, including:
- Disposable lunch boxes
- Fruit boxes
- Egg trays
- Food packaging
- Product packaging
- Food plates
- Biscuit boxes
- Seedling trays
The final product depends on mold design, material selection, sheet thickness, forming depth and cutting method. For a deep round plastic cup, a plastic cup making machine is usually more suitable. For flat or shallow packaging products, trays, lids and food boxes, a three-station thermoforming machine is normally the better direction.
Auxiliary Equipment for a Complete Line
A complete three-station thermoforming line usually needs more than the main forming machine. The provided auxiliary equipment image shows support equipment such as:
- Chiller
- Vacuum pump
- Air compressor
- Gas storage tank
- High precision refrigerated dryer
- Air filtration system
- Sheet material supply
- Forming, cutting and stacking mold
For overseas buyers, confirming these auxiliary systems before shipment is important because missing support equipment can delay installation after the machine arrives.
What Buyers Should Check Before Buying
Before purchasing a used three-station positive/negative pressure thermoforming machine, buyers should check:
- Actual machine photos
- Parameter plate or parameter image
- Forming area and sheet width
- Material and thickness range
- PLC and control screen condition
- Servo system and motor condition
- Heating, forming, punching and stacking movement
- Mold matching requirement
- Auxiliary equipment list
- Whether the project also needs a sheet extrusion line
A used machine should be matched with the buyer's target product, not selected only by model name.
How This Fits the WEIXIN Turnkey Direction
For customers who want a full production line, WEIXIN Machinery can help evaluate both the thermoforming machine and the upstream sheet extrusion requirement. The correct direction may be:
- Thermoforming machine only, if the buyer already has stable sheet supply
- Thermoforming machine + molds, if the buyer needs a product-specific solution
- Thermoforming machine + sheet extrusion line, if the buyer wants to produce sheet in-house
- Full line with auxiliary equipment, if the buyer wants complete installation preparation
This supports the main site positioning: not only selling one machine, but helping buyers build a workable plastic packaging production line.
FAQ
What products can this used three-station thermoforming machine make?
It can be used for disposable lunch boxes, fruit boxes, egg trays, food packaging, product packaging, food plates, biscuit boxes and seedling trays, depending on mold design and material selection.
What is the forming area?
The forming area shown in the provided parameter image is 910×710 mm.
What materials can it process?
The provided parameter image lists PP, PS, PET, PLA and PVC materials, with sheet thickness range of 0.2-2.0 mm.
Does a thermoforming machine need a sheet extrusion line?
If the buyer already has stable sheet supply, the thermoforming machine can be used with purchased sheet. If the buyer wants to control sheet quality, thickness, width and long-term material cost, a sheet extrusion line should be considered.
Need a Used Three-Station Thermoforming Machine?
If you are planning to produce food containers, trays, lids, fruit boxes, egg trays or other plastic packaging products, send your product photo, size, material, sheet thickness and target output. WEIXIN Machinery can help check whether this used 910×710 three-station positive/negative pressure thermoforming machine fits your project and whether you also need molds, auxiliary equipment or a sheet extrusion line.
