A tray sealing machine can replace pneumatic sealing with electric drive for controlled mold movement without compressed air. The DQ250T uses electric drive, automatic film feeding, photoelectric and disc sensors, a Teflon-coated sealing plate, and a sliding mold. Its listed speed is 7–8 cycles/min, with a maximum tray size of 200 × 140 × 120 mm.
How Electric Drive Changes Sealing Control
A pneumatic system relies on compressed air and cylinder movement. Electric drive transfers motor torque through a mechanical transmission, while a servo motor can add closed-loop position and speed control through encoder feedback.
From Drive Force to Seal Quality
- Motor: Produces controlled torque.
- Transmission: Transfers motion to the sealing mechanism.
- Mold: Moves toward the tray flange.
- Sealing: Maintains the required position and dwell time.
For equipment without a dedicated servo motor or servo control program, an electric drive can still provide stable mold movement through its motor and transmission system.
Why Servo Control Can Improve Repeatability
A tray seal machine must coordinate pressure, temperature, dwell time, and film position. Servo control allows programmable motion and position feedback.
- Adjustable acceleration and deceleration
- Controlled mold positioning
- Encoder feedback
- Programmable motion profiles
| Control Factor | Electric Drive | Servo Drive |
|---|---|---|
| Motion control | Motor and transmission | Closed-loop control |
| Position feedback | Sensor-dependent | Encoder feedback |
| Speed adjustment | Basic | Programmable |
| Motion profile | Fixed or limited | Adjustable |
| System complexity | Lower | Higher |
Sensors and Film Feeding
The DQ250T uses photoelectric and disc sensors for automatic film feeding. A plastic container sealer machine also requires accurate tray positioning, film tracking, temperature control, and mold movement.
Film feeding: Controls film advancement.
Detection: Monitors film position.
Temperature: Maintains sealing conditions.
Motor: Synchronizes mold movement.
DQ250T Design and Capacity
The DQ250T lists a maximum film width of 245 mm, maximum film diameter of 180 mm, weight of 29 kg, and dimensions of 490 × 360 × 630 mm. The tabletop machine uses a stainless steel structure and anodized 6061 aluminum mold.
The Teflon-coated sealing plate reduces film adhesion during operation.
Choosing the Right Sealing Mechanism
A food container sealer machine should match tray material, film type, sealing temperature, and mold geometry.
- Tray: PP, PET, aluminum foil, and degradable pulp are listed for the DQ250T.
- Film: Width and sealing temperature must match the mold.
- Dwell time: Sufficient heat and contact time are required.
- Flange: Tray geometry must match the sealing surface.
A food tray sealer machine can produce weak or distorted seals when temperature, pressure, or dwell time is incorrectly set.
Electric Sealing for Food Packaging
The DQ250T is designed for ready-to-eat and quick-frozen food packaging. Its sequence includes manual tray feeding, sealing, film cutting, and automatic tray discharge.
A food container sealer machine suits applications where tray sealing and compact operation are the main requirements.
Practical Design Checks
A tray seal machine should be evaluated from the complete sealing cycle:
- Confirm tray dimensions and flange geometry.
- Match film width and material.
- Set the correct sealing temperature.
- Check motor torque and mold movement.
- Verify sensor alignment.
- Confirm dwell time and cutting position.
For a servo-based configuration, encoder feedback, motion control, temperature, and sensor signals should be coordinated through the control system for repeatable sealing movement.
DQ250T electric tray sealing machine we manufactured, is suitable for factory packaging of ready-to-use foods in stores and supermarkets or all kinds of quick-frozen foods. This table top machine is compact, need less space, while trays are not filled with fresh-keeping gas after sealed. The electric sealing machine is easy to operate, trays fed by hand, then trays sealed, cut, sliding out automatically. The main structure of the product is made of stainless steel, and the mold is anodized with 6061, which is safe and sanitary.
