Aluminum Manufacturing Controls



Spectographic Analysis

  • Spectrography equipment is used to check the composition of the aluminum: Initial analysis of incoming materials to ensure suitability before they are used in the production line.
  • Monitoring of the aluminum composition inside the smelting furnaces, collecting the data needed for full traceability of the products manufactured and marketed by Industrial Gradhermetic.
  • Creation of an alloy label for all smelted and cast plates.

Property Analysis

During the rolling process, the data obtained from tests conducted in the metallographic laboratory are included in the production sheet for each coil:

  • Stress rupture
  • Elongation or drawing capacity
  • Hardness
  • Structure size

Only materials that comply with all required parameters are sent to the next manufacturing step.

In-Process Control of Coil Coating

Industrial Gradhermetic has been a member of the European Coil Coating Association (ECCA) since 1975. Its finish verification laboratory is responsible for ensuring that the coils produced at the company's facilities meet all necessary requirements for subsequent application:

  • Color
  • Strength
  • Durability
  • Aging
  • Elasticity

Product Production Controls

The Manufacturing Department continually adapts its in-process controls to ensure the design parameters of the Technical Department. These parameters are checked and recorded by the Quality Control Department, which also fills out a tracking sheet for each product.
