Technical regulations and tolerances according to EN 604-2 standard
This regulatory document defines strict tolerances for geometric parameters and the shape of cast billets intended for subsequent forging, made of aluminum and its alloys for general industrial use. Compliance with established standards is critical for ensuring the stability of the mechanical properties of final products during further thermal and deformation processing.
Compliance with metallurgical production standards
During the production of semi-finished products at EV Group China facilities, we strictly adhere to the regulations set forth in the current version of the standard. The chemical composition of the aluminum alloys used fully complies with EN 573-3 specifications, which guarantees the homogeneity of the metal structure. Requirements for delivery conditions, quality control methods, and product acceptance are regulated by the EN 604-1 standard, ensuring that products meet international engineering standards.
EV Group China engineers carry out multi-stage control of billet geometry at the casting stage, minimizing machining allowances and ensuring high dimensional accuracy, which allows for the optimization of our clients’ production costs.
