Specify your application
Workpiece & process
Provide the material grade, billet and finished-part dimensions, forging sequence and production target.
Equipment & interfaces
Identify the required force and energy, die envelope, handling arrangement, power supply and installation country.
Technical review
What is included in the proposed supply?
The technical proposal will define the machine, tooling interfaces, controls, documentation and agreed options.
Can automation be included?
Share the process layout and target cycle. Handling, heating, lubrication and safety interfaces must be reviewed as a system.
Which documents should I request?
Request a model-specific datasheet, general arrangement, foundation and utility requirements, acceptance-test plan and applicable conformity documents.
