Formech 686 (3 phase) Features
Pre-stretch
Pre-stretch enables the user to pump air into the heated sheet, creating a bubble to avoid thinning of material with deeper tools.
Vacuum gauge
A visual indication of consistent vacuum pressure being applied (pressure in Hg / bar).
Quartz heaters with variable standby
Quartz heaters have the benefit of a rapid response and high efficiency resulting in time and energy savings.
Vacuum & release
After the formed part has cooled, air is forced between the mould and the sheet to help it release.
20 program memory
20 nameable memory presets enable convenient recall of settings for each application.
PLC Control with 5" colour touch screen
6 independently controllable heating zones
Provide rapid heat response with a greater range of control to form challenging shapes and materials.
Dry rotary vane pump 16m3/h
Auto-level
Avoids material sag during the heating cycle and maintains an even distance between heater and sheet whilst providing the user with an audible indication the material is ready to form.
Vacuum flow regulator
Precisely regulates vacuum flow rate when a greater level of control is required with demanding applications.
Pneumatic table
Lifts tool table quickly and precisely making effortless operation, even with heavy tools. Twin controls avoid accidental activation.
