Preform
PRE-CAGE ASSEMBLERS
The PREFORM C and PREFORM C8 plants offers a complete and versatile solution for precast production, guaranteeing high levels of quality, productivity and flexibility.
Functionality:
Universal pre-cage assemblers for automatic welding stirrups with two or three longitudinal wires ("supporting") at programmed distances ("steps").
Production of pre-cages of various shapes and sizes with short assembly times and high quality.
Versions for 4 to 8 mm bars and 4 to 16 mm stirrups.
Benefits:
Fast and precise production process with one operator.
Compact and modular configuration to optimise space.
Production of fully automatic pre-cages with stirrups and rings of different shapes and sizes.
Controlled current welding that preserves the characteristics of steel and reduces energy consumption.
Independent programming of welding heads for diameters and clamp positioning.
Welding sequence adaptable to available energy.
Lateral insertion of the stirrups for easy and safe loading.
Superior productivity to machines on the market.

Preform Advanced
AUTOMATIC PRE-CAGE FORMING. COMPACT. INTELLIGENT. READY FOR ASSEMBLY.
PREFORM ADVANCED is an automated system designed to transform individual stirrups (Squared-Trianglular-Circular) into pre-assembled cages by sequential welding with longitudinal wires. The machine enables the efficient production of pre-cages, significantly reducing downstream assembly time and simplifying handling, transport and site operations. Derived from the proven PREFORM technology, the new generation introduces advanced automation, improved welding control and enhanced production flexibility.
