Thermal Bolts

Automatic Systems For Extrusion Dies

Thermal Bolts are die conversion kits that convert manual extrusion dies to automatic extrusion dies.

Thermal Bolts are systems for automatically controlling thickness profiles of films and sheets.
Thermal Bolts can be controlled with all modern thickness gauges.

Options of Thermal Bolts

Push only

Automatic die lip adjustment through push mechanism of thermal bolts. System of choice for film and sheet extrusion dies.

TB_PUSH_ZOOM

Push-Pull

Automatic die lip adjustment through push and pull mechanism of thermal bolts. Applications that demand faster response and even greater precision to die adjustments. e.g. Coating & Lamination extrusion dies.

Applications

Thermal Bolts are extrusion die conversion kits for Extrusion Die OEM’s and End Users with existing manual Dies.

Applications include:

Flat Extrusion Dies for Film and Sheet (PP, PE, PET, PVC, PS, HIPS, ABS etc..) Extrusion Coating & Lamination Dies BOPP and BOPET Dies Cast Film Dies.

Technical Specifications

Heated steel bolts expand depending on the controlled heating power and this moves the die lip according to the thickness control. The heated steel bolts are in a cooling air flow. The heating cartridges inside the bolts are regulated by a controller.

Technical Specifications Thermal Bolt
Total adjustment range 300 µm
Division (bolt spacing) 30, 28, 25.4 mm (1″)
Heating cartridge power 80 W
