Checking dies
All beams of circular cross section through output control:
- visual – magnifier at a magnification of 4–12× is checked quality of processing cores, which must be shiny, smooth, without grooves and holes,
- dimensional – girders inside diameters are measured and control pins such that at the lower tolerance control mandrel must pass a measured die and at the upper tolerance of the nominal diameter must not pass.
If you require a certificate (Declaration of Conformity), you have to apply for it.
Technical specification of the order
On Order must be marked:
- Subscriber
- type dies or diameter of the sleeve and the core
- nominal diameter d1(mm) and tolerance
- amount
- die geometry (towing cone size 2 alfa, the calibration length l3 or how to use a metal removal rates wires)
If parameters are required other than those listed above dies must be properly marked on the order form.
Packaging
Standard packaging is performed in cardboard boxes, or to normal Euro pallet.
