Main frame configuration
  • Modular frame design, built in steel, welded and painted with protective paint. Machine frame is provided with doors of clear policarbonate that allows to see the inner parts of the machine.
  • Material index system by means of two spike chains of 1/2 inch, pre-streched and paired. Index system is driven by a 1.5 kW motor controlled by a frequency inverter and one encoder. Chain punches the material from the top so dust cannot fall into the film.
  • Manual adjustment of the spreading of the chain rails according to the width of forming material.

 
Individual station description
 
Heating station

Upper heater with infrared resistances and a regulation system of shutters built in stainless steel which allows adjusting the heating area according to the forming index. The lenght of the heater is two times the maximum index of this machine and there are several heating clusters, each one capable of its own temperature adjustment.

Resistances are ceramic and wiring goes through stainless steel wireways to ensure ther are maintenance free.

Total installed power in the heater is 8 kW.

Forming station

Thermoforming action is done by vacuum assisted with air pressure (up to 2 bars). Forming is always below the material line, being maximum forming depth 60 mm. Forming platens have a closing force og 18.5 kN.  Lower platen is motioned by a vertical pneumatic cylinder in combination by a mechanical toggle system. Upper platen is motioned by a direct cylinder. Both platens run independently.  Clamping frames are motioned by their own pneumatic cylinders.

This design allows processing of thick forming materials (up to 0,8 mm).

Thermoforming process forces heated material against a mould to produce desired shape. The forming cycle begins by sealing the clamped preheated film to the mould and applying a moderate vacuum action. Then, while the sheet is still within the proper forming temperature range, strong vacuum action combined with air pressure is applied to form the sheet onto or into the mould. Once formed, vacuum action is reverted and air is blown to separate the material from the mould.

This forming process is usually used in combination with plug-assist forming. This technique distributes the material more evenly over the mold thus achieving deeper draws.

Sealing station

Sealing of the lidding material is acomplished by applying pressure and temperature in the sealing press. The lower platen is driven by a membrane pneumatic cylinder to move the platen in the vertical direction with a maximum closing force of 29 kN.

The upper platen remains static and tilts over itself to replace the tooling.

The sealing press is provided with a pressure switch that reads the pressure applied and triggers an alarm in case sealing pressure differs from the preset value.

The sealing tool placed in the upper platen is heated and it is provided with a temperature controller. There is a probe built into the sealing plate which reads the actual sealing temperature and makes sure it remains constant through each cycle,.

Steel rule die-cutting station

Sealed packages are trimmed from the web with steel rule die. This method of cutting is simply a sharpened metal cutting edge or knife mounted on a  die board. Die is mounted on a press that has enough force to close smoothly and cut completely through the sheet. As the cut progresses, the press consistenly brings the die to the same line on the backing plate.

The lower platen is driven by a pneumatic cylinder assisted with a mechanical toggle system which multiplies the closing force. The upper platen remains static and the position is manually adjusted by a system of spindles.

To increase efficiency of cutting the cutting edge is heated by a contact heating plate.

The closure force of the die-cutting is 117,6 kN.

Discharge blister station 

Formed packages are discharged by a tooling provided of suction cups which holds each package from the top and bring them down onto a 90 degress placed conveyor belt.
