The Production Process

At first glance, one might not fully appreciate the significance of CAPT's products.  By mastering the art of melting, casting and machining aluminum, CAPT's manufacturing processes result in the highest quality aluminum products.  These products become part of legendary Honda automobile engines - engines known for efficient operation, reduced friction, higher output and enhanced gas mileage.

Key components of CAPT's production process

  • Prior to mass production, computer-generated testing is done to determine the strength, durability and mineral composition of the aluminum alloy that will become a CAPT product.
  • Aluminum ingot bars are melted in furnaces at a temperature of 1400°F.
  • CAPT has 4 different types of casting under one roof - gravity, low pressure, high pressure and tilt.
    • Depending upon the specific application requirements, aluminum castings are heat-treated to achieve the desired finished part material properties. CAPT has T-6 and T-7 heat treatment processes which are tailored to specific aluminum alloys.
    • After heat treatment, parts are machined to exact tolerances, using precision CNC turning and milling equipment. CAPT's machining processes are highly automated using specialized material handling devices as well as flexible robots.

Some key technologies used at CAPT

  • High efficiency melting furnaces which maintain aluminum alloy purity.
  • Sophisticated die designs which run on specialized casting incorporating computerized die cooling technology.
  • Advanced Piston surface treatments which reduce engine friction to improve fuel economy.
  • X-ray inspection of critical components to verify the material integrity.
  • Product testing equipment for suspension components simulates severe loads in automobiles in an accelerated fashion.
  • Material testing equipment allows in house analysis of material properties.
  • CAPT in house developed traceability is used throughout the manufacturing process and is the most advanced in our industry. This allows manufacturing conditions to be traced to unique parts.
  • CAPT associates perform a series of quality checks to assure high quality to the customer.
