The material such as PP, PE, PS, PVC, PET, PETG, EPS, HIPS, HDPE, PMMA in soft film could be processed by this machine, it is an ideal vacuum forming machine for blisters, clamshell, plastic containers, disposable lunch box, fruit trays, egg trays, dishes, bowls, lids, medical packaging such as ampoule trays and vial trays, etc.
1. PLC control system with touch screen
2. Independently controllable heating zones, heated by far infrared ceramic heating bricks
3. Pneumatically powered clamp frame
4. Automatic cooling system with industrial chiller and spray guns
5. Automatic vacuum forming system
6. Steel components coated with polyurethane
1. Feeding system: Auto feeding with inverter motor or servo motor driven, high speed, accurate and stable, digital length adjustment. Adopts special chain rail to ensure no deviation and vibration, wearing well.
2. Auto temperature control system using intelligent compensation control, heating up fast, stable, low energy consumption and with long life heating bricks.
3. Two-stage vacuum, vacuum-delay.
4. Electric adjust the position of the upper liftgate.
5. Processing flow: Auto Feeding → Heating → Forming → Cooling → Air Blowing & Releasing from mold → Cutting.
6. This machine consists of Heating system, Forming system, Vacuum system, Pneumatic system, Cooling system and Control system.
7. 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 one 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).
8. Cooling system is composed of air-cooled industrial chiller, spray gun and circulating water cooling chassis, make the forming speed faster and guarantee the molding quality.
9. Apply air pressure to release the molding from the mold, damage of the molding in the releasing process is avoided.
10. Two-stage vacuum sucking to ensure the thick sheet is easy to form and to improve the molding quality.
11. 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.
12. Machine cycle status is clearly visible at a glance and all parameters can be adjusted in real time without interrupting the current cycle.
13. 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 number.
14. Imported electrical and pneumatic components from International well-know manufacturer make the machine features reliable quality and wearing well.
