sandwich (dual) heater banks: pneumatic driven or electric driven using telescopic rail design
heater control using IR, quartz or halogen elements
preblow, sag, IR sheet temperature probes, proportional vacuum, and other such features.
Sheet Loading System
Manual Sheet Loading
The Vacuum forming process starts as the operator loads a thermoplastic sheet made from materials such as ABS, HIPS, PMMA, PP, HDPE, PC, PETG, LDPE etc. onto the machine.
Automatic Sheet Loading Option
The machine features electrically driven automatic sheet loading system. This variant loads a stack of cut sheets into an additional unit. At this stage, vacuum pad picks the sheet and transports the sheet inside the forming unit. Once the part is formed, the formed part is also automatically extracted out of the machine and dropped into the exit chute. The 2nd generation Automatic Sheet Loading Unit (ASL) has been redesigned in 2018. The design includes a servo driven chain mechanism which drives a vacuum-pad based end-effector to transfer the thermoplastic sheets into the main machine using the telescopic rail. The system can hold thermoplastic sheets in cut-sheet format ranging from 2 mm upto 12 mm. The autoloader has a pneumatic push-off that pushes the part off the machine into collection area.
Roll Feeder Option
The Roll Feeder add-on is a handy feature that is used for thin sheet materials that come in rolls. The sheet can be cut to a required length either before it is fed into the system, or after it is rolled out. The roll feeder unwinds the sheet into the main unit where it is cut and conveyed into the forming station automatically. Once the part is formed, the chain transport mechanism moves the formed part out of the machine and drops it into the exit chute.
Universal Motorized Bottom Frame System
The machine features servo driven motorised window plate adjustment - this allows the operator to adjust the frame in both axes by mentioning the widow size on the touch screen HMI. The window plate system consists of 4 individual plates that move against each other independently. The 2nd generation Universal Frame Adjustment System has been redesigned in 2018. The design includes four servo motors working in synchronization to change the sheet clamp sizes as per the product. The pneumatic cylinders at the bottom of the plates lift the plates and the plates roll on ball-roller bearings to infinitely adjust with each other while maintaining absolute seal in the area required for the vacuum forming process. This feature reduces the frame change-over time and eliminates the need to store different frames for every product size.
Motorized Top Frame System
he machine features servo driven motorised top frame adjustment - this allows the operator to adjust the frame in both axes by mentioning the frame size on the touch screen HMI. The motorised frame system consists of 2 individual driven servo motors that adjust the frame as per the size mentioned on the HMI. The 4th generation Automatic Frame Adjust has been redesigned in 2018. The Top Frame also consists of pneumatic mechanism that can hold the part and then release it over the automatic sheet loader upon completion. The system contains holders that can be adjusted as per the part size.
Mould Platen System - Table 1
Pneumatic Mould Platen System
In this option, four cylinders, synchronised by four rack and pinions, drive the movement of the mould units. The area at the bottom of the machine where the bottom tool to be used for vacuum forming of the component is kept has been called Table 1. The tool which can be made of MDF, Epoxy, Machined Aluminium or Cast Aluminium using material like ALWA is kept on Table 1.
Servo Driven Mould Platen System Option
This add on facilitates faster mould movement by reducing the distance between the tool and the sheet. Not only does this function bring down cycle time but also plays a vital role in improving the forming quality.
Quick Mould Change System
The option for Quick Mould Change technology is available on select models. Quick Mould Change technology reduces the mould load time to less than 5 minutes. This is well suited for industries that have quick mould changeovers. These machines come with an automatic frame clamping mechanism that automatically clamps the frame on the machine.
Plug Platen System - Table 2
All machines are equipped with Pneumatic Plug Platen Movement with Stroke Adjustment.
Plug Platen with Motorised Stroke Adjustment option
Plug Assist can be provided with a Motorised Stroke Adjustment Plate so that you can use the HMI to set the height of the plug with Motor.
Servo Driven Plug Platen System is also available as option.
The PF1 series features both, single and sandwich heating systems (with top-bottom heating) for varying requirements. This gives the operator the flexibility to choose different configurations for varying results.
Similarly, the heating system also features zone settings that enables even heat distribution and flexibility to handle multiple job orders on the same forming bed. All machines have zonal heater control with each zone of two elements.
The system features Infrared Ceramic Heating Elements by default. The machines also come with optional Quartz Heating Elements
Infrared Sheet Temperature Reader Option
Where exact sheet temperature is required to be measured optional infrared sheet temperature reader can be provided in the top heater.
The photo sensor senses the height of the pre-blow sheet and regulates the air in the chamber to provide pre-blow control. The Preblow is essential for an better distribution of sheet thickness and to prevent excessive sagging of sheet during heating.
During the heating of sheet the sagging of sheet is controlled by photocells mounted below the sheet. This allows to maintain proper sheet to heater distance during heating.
All Machines are equipped with high speed cooling blowers for efficient cooling of formed parts. The machines also come with optional water mist spray for faster cooling.
Where there is a requirement of ejecting the parts at specific temperature infrared sheet temperature reader is also provided for measuring the temperature of the formed part during cooling.
All machines come with a touchscreen Human Machine Interface with a friendly and simple to use interface. The screens are designed to suit a thermoforming operator’s mind and help him to easily use the machines, view important parameters assess machine performance. Machines also come with alarms and messages for preventive maintenance and diagnostics. All the parameters can be stored in recipes in the HMI.
PF1 machines are available in a variety forming area and stroke options. These machines can also be designed to achieve special forming areas and depths as required.
