The stage plan:
Basis of the design
Stage plans from Walter Schneider enable economical production. Our decades of experience mean that we take the different framework conditions into account to achieve an efficient, practically rework-free production result using optimized forming steps.The stage plan is configured so that
- the component is given the optimum desired geometry
- the material reaches all ends of the engraving as close to simultaneously as possible
- material flow is enabled at room temperature
- the lowest possible pressing forces are necessary
The stage plan forms the basis for:
- Tools
Our tools are designed to ensure optimum manufacturing of the pressed part using the planned facilities in line with the stage plan using the planned facilities - The forming machine
The forming press is defined in parallel with configuration of the stage plan. Data such as the compressive force, ejector force, working capacity, die mounting area and the force-displacement characteristic are key parameters governing the manufacture of components - Inspection of quality criteria
Surface, dimensional, position and shape tolerances are decisive for tool and die precision and the selection and number of required pressing operations - Economic considerations
To ensure the most economical solution for our customers, we define the most cost-effective sequence or combination of processes, and also check whether different production options would provide a higher quality or more economical solution than cold forging. Consequently, it is possible that the feasibility analysis favours the manufacture of blanks rather than cold forged parts on some occasions.
We produce all the designs for our press step sequences in-house. The design drawings form the basis for tool production in our own toolmaking department.
