We have completed a project involving the design and delivery of an adjustable, horizontal double mould intended for the production of precast stair flights. The investment was carried out in response to the client’s need for a flexible and precise stair forming system capable of producing elements with varying parameters.
Mould Functionality
The developed solution allows for full customization of the geometry of the manufactured stair flights, including:
- Forming up to 34 stair steps – either a single flight with 34 steps or two flights whose total number of steps is 34,
- Forming both landings (upper and lower),
- Simultaneous production of two flights in a single cycle,
- Full adjustment of step height and width, including:
- Step width adjustable between 200–320 mm (with plywood shuttering),
- Step height adjustable between 150–200 mm,
- Overall flight width adjustable up to 1600 mm, achieved via a dedicated magnetic system.
Project Characteristics
The mould was designed using durable and proven adjustment mechanisms, ensuring high repeatability of elements and stability of parameters throughout the production cycle. The construction is based on solutions that allow for quick mould reconfiguration, reducing setup time for the production of different stair variants.
Outcome
The delivered mould meets the requirements for flexibility, ergonomics, and precise geometry reproduction. The system provides a tool for producing varied stair flights while maintaining high quality and repeatability of the precast elements
