Application: 

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, fruit trays, egg trays, dishes, bowls, lids, medical packaging such as ampoule trays and vial trays, etc.

Product Introduction: 

Basic units:

1. PLC control system with touch screen

2. Independently controllable heating zones

3. Automatic cooling system with industrial chiller and spray guns

4. Automatic vacuum forming system

5. Steel components coated with polyurethane

6. Far infrared ceramic heating bricks

Main feature:

1. This machine adopts the latest international plastic sheet molding technology and crafts, with the design of mechanical electrical integration, using PLC control, the whole system realizes the HMI (human machine interface).

2. It is suitable for male mold and female mold forming, which adopts the integration of positive and negative air pressure to ensure good molding quality and precise molding size.

3. There are four processing parts: forming, cutting, stacking & counting, which are simultaneously completed, greatly increased the production speed.

4. High speed, low noise, high reliability and convenient to maintenance.

5. Feeding, cutting & stacking adopt servo motor control, high speed, accurate and stable.

6. Forming, punching and cutting by the system of hydraulic drive, automatic oiling, eliminate unnecessary trouble and pollution of the product.

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

8. Two-stage vacuum, double times on mould, vacuum-delay.

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

10. The heating box temperature control system adopts full computerize intelligent automatic compensation controlling, heating brick adopts digital input, has a high precision fine-tuning, uniform temperature, fast temperature elevation (only 3 minutes from 0~400℃), stability (not influenced by external voltage, temperature fluctuation is less than 1℃). Low energy consumption (energy saving about 15%), heating box service life is long, etc.

11. Heating system: Far infrared ceramic heating bricks with independent control system, each ceramic heating brick is controlled via PLC integration control on touch screen to ensure the sheet is heated uniformly over its entire surface area and throughout its thickness. Adopts fully enclosed furnace to reduce heat loss.

12. Cooling system equipped with air-cooled industrial chiller, spray gun and circulating water cooling chassis, make the forming speed faster and guarantee the molding quality.

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

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

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

16. 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.

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

18. Special chain rail, no deviation and vibration, wearing well.
