In a battery of induction and retaining owens the A-356 Alloy (aluminum and silica) is prepared. From here, metal is sending to foundry area where is processed into the VP moulding machines.

The VP process technology is also knowed as counter-pressure and allows a reliable wheel moulded. 

This technology guarantee one piece wheels without internal defects when operate under  well controlled parameters and know how.  

 
Once the foundry and moulding process ends, wheels get into thermical treatment to release internal efforts and give surface temper. This stage gives the wheels good conditions for machining stage.
 
Thermical treatment line is continuous type, and robot controlled. Alloy properties are keeping and increase the process reliability.

Each CTA wheel is made to be perfect coupling with many vehicles and give a clean installation.
 
 

When a wheel is ready and verified, it pass through the paint cabin and final furnished to obtain a perfect item.

CTA uses a electrostatic re-treatment to polymerize the wheel surface to eliminate corrosion risks or thermal burning. This treatment gives also an elegant appearance to the product.
