Inspection of the Process Correctness
The plating quality inspection shall be carried out with measuring tests using three pieces from each barrel or rack. The measurement is carried out using a non-destructive method with the X-RAY device. Moreover, our operators check the plating visually (in particular, they focus on the integrity and color of parts).
The correctness of plating (in particular, the integrity and color) is also visually checked by our operators.
Certificates, Certificates of Conformity
The certificate of conformity is issued on the basis of measured values which are stored in the internal system. The certificate guaranteeing conformity shall be drawn up upon the customer’s request for each article of goods and delivery separately. The certificates are available for downloading in the
client zone.
De-embrittlement
The hydrogen bake out cycle of parts consists in heat treatment at around 200 °C for 2 to 24 hours, depending on material hardness. The hydrogen bake out cycle must begin immediately after galvanizing. Through the hydrogen bake out cycle, the parts made of harder materials (over 1,000 Rm) are protected against the risk of hydrogen charging and hydrogen embrittlement of the matrix, of which they are made.
Corrosion-Resistance Testing
The tests of the prescribed corrosion resistance for galvanized parts and parts with zinc-nickel treatment are carried out internally in our laboratory, using salt spray tests. The salt spray tests conform to “automotive” standards, and their output is always a report indicating the result.
The internal tests of corrosion resistance also help us check the correct process settings. The corrosion-resistance tests are also offered as a separate service.
Common standards, based on which the neutral salt spray (NSS) tests are performed: DIN 9227, ASTM B117,...
