Application:

The material such as ABS, PP, PE, PS, PC, PVC, EPS, HIPS, HDPE, PMMA, PET, PETG in thick sheet could be processed by this machine, it is an ideal vacuum forming machine for luggage, automobile parts like car foot mat, car trunk mat, car bumper, light box, plastic board, plastic containers, plastic pallet, plastic helmet, plastic covers, fruit tray, apparatus shell, instrument panel, refrigerator inner liners, etc.

1. Overview:

This machine consists of Heating system, Forming system, Vacuum system, Pneumatic system, Cooling system and Control system with reasonable structure. To achieve cost-effective, the design of this machine is optimized, its production speed is fast and 50% energy saving. 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

2). Independently controllable heating zones

3). Pneumatically powered clamp frame

4). Automatic cooling system with cooling fans and spray guns

5). Automatic vacuum forming system

6). Steel components coated with polyurethane

1.2 Main features:

Main feature:

1). Processing flow: Manual Feeding → Heating → Pre-stretching → Forming → Cooling → Air Blowing & Releasing from mold → Clamping Frame Rise → Manual Pickup Product.

2). This machine consist of Heating system, Forming system, Vacuum system, Pneumatic system, Cooling system and Control system.

3). Heating & temperature control system: Adopts fully enclosed furnace to reduce heat loss. Adopts far infrared ceramic heating bricks with independent temperature control module to ensure the sheet is heated uniformly over its entire surface area and throughout its thickness. The temperature control module for the heating brick is SCR voltage regulator which operating by setting voltage up and down. Each heating brick is controlled by single SCR voltage regulator, means "one to one" control mode, different voltage acquires different temperature. (Integrated circuit voltage regulator is optional, in this way, the voltage is PLC controlled and voltage setting is operated on touch screen).

4). Sheet level (Auto-level): A photoelectric beam (photoelectric eye) is activated under the sheet during the heating cycle. If the sheet sags down and breaks the beam, then a small amount of air is injected into the bottom chamber under the sheet, thus lifting the sheet to stop it from sagging until the sheet clears the beam.

5). Plug assist is optional: Plug assisted vacuum forming is used when straight vacuum forming is unable to distribute the thermoplastic sheet evenly to all areas of the mold. Where a deep draw is required, a device know as top plug is used to push the sheet into the mold before the vacuum is applied to help spread the sheet out more evenly.

6). Cooling system equipped with low noise centrifugal fan. Spraying mist is available whereby nozzles are attached to the fans and a fine mist of water is directed onto the sheet.

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

8). Two-stage vacuum sucking to ensure the thick sheet is easy to form and to improve the molding quality.

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, that means when processing the same project in next time, there is no need to set the operating parameters again, just touch the project name or project code.

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

3. Working flow:

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 63KW.

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
