Application:

The material such as PP, PE, PS, PLA, PVC, PET, PETG, EPS, HIPS, HDPE, PMMA in soft film could be processed by this machine, it is an ideal full auto vacuum forming machine for blisters, clamshell, plastic containers, fruit trays, egg trays, dishes, bowls, lids, medical packaging such as ampoule trays and vial trays, etc.

1. Outline:

The equipment consist of heating system, forming system, vacuum system, pneumatic system, cooling system and control system with reasonable structure. It is designed in line with the principle of energy saving and its production speed is 60% faster and 50% energy saving than single station thick sheet vacuum forming machine. It is easy to operate with HMI. The machine has acquired a number of national patents, it can be customized according to customers' requirement.

1.1 Basic units:

1). PLC control system with touch screen/HMI

2). Independently controllable heating zones, heated by heated by Elstein ceramic heaters

3). Vacuum integrated high Pressure Forming system

4). Accurate and stable punching, cutting & stacking system

5). Pneumatic system & vacuum system

1.2 Main features:

1). It is suitable for male mold and female mold forming, which adopts the integration of vacuum and high pressure forming to ensure good molding quality and precise molding size.

2). Processing flow: Auto Feeding → Heating → Forming → Cooling → Punching →Cutting → Stacking /Counting→ Waste Material Winding, greatly increased the production speed.

3). This machine consists of Heating system, Vacuum integrated high Pressure Forming system, Pneumatic system and PLC Control system.

4). Feeding, punching, cutting & stacking adopts servo motor control, high speed and accurate.

5). Forming, punching and cutting station is driven by eccentric crank linkage structure, controlled by Delta/Mitsubishi servo motor. Guiding pillars made of superior quality bearing steel Gr15 and hard chromium plating, designs for good rigidity, accurate performance and excellent abrasion resistance, which contributes to the working life of equipment.

6). The bushing of crank linkage mechanism is made of superior quality quenched and tempered steel 40Cr, which is imported from Japan, designed for high rigidity, good resistance of abrasion and pressure, which ensures more than 40000 hours working life.

7). Tool change system of optimized ergonomic design which shortens the time for tool change.

8). Apply air pressure to release the molding from the mold, damage of the molding in the releasing process is avoided.

9). Machine cycle status is clearly visible at a glance and all parameters can be adjusted in real time without interrupting the current cycle.

10). The PLC program offers saved memory for project to project recognition.

11). Imported electrical and pneumatic components from international well-know manufacturer make the machine features reliable quality and wearing well.

12). Special chain rail, no deviation and vibration, wearing well. Guide rail adopts toothed roller chain, cooling pipelines inside the aluminum alloy beam, high cooling efficiency and save water.

4. Installation environment:

Avoid direct sunlight, moisture or dusty places; machine should be placed on a solid and flat floor. Check whether the floor loading capacity meets the requirements if install the machine on the second floor or above, place the machine on the beam of the floor so that the gravity is evenly distributed. There is a heating device in the machine, the material will volatilize harmful gases during the heating process, therefore, the machine should be placed in a ventilated place, and above 1500mm away from the wall for easy maintenance.

5. Electronic control method and requirements:

5.1 Power supply: Three-phase five-wire system, i.e., three-phase power supply, one-phase ground wire, and one-phase neutral wire.

5.2 Control requirements: The control system should be away from flammable, explosive, high temperature, high humidity and high corrosion area. The control cabinet should have good heat dissipation conditions. All wiring must be higher than the ground and cannot be directly attached to the ground. The control system is placed at the place where the operator can easily operate and observe. The equipment installed a necessary emergency stop switch. Machine has overload protection and short circuit protection function. When the circuit of the machine hits the shell, the control system cuts off the power supply within 0.1 second.

6. Installation requirements:

Main power: 3P 380V AC 50/60Hz or customized, in total 110KW.

Water supply: water inlet pipe (inner diameter Φ15mm)

Air supply: air inlet (inner diameter Φ32mm)

Air compressor: At least 15KW

Exhausting: at least 1.8m3/min

Air pressure: 0.6-0.8Mpa
