GPT is the preferred choice when it comes to High Quality Gold Plating Services for Engineering and Industrial Applications. Gold plating is an excellent choice for plating contacts and connectors utilized on instruments and components for virtually every industry. Because of its inert properties, gold does not oxidize or chemically react under normal & some extreme conditions. This is due to the high corrosion resistance of the gold deposit, maintaining its high conductive integrity.

Our gold process is not only applied to contacts and connectors, but also on components for it’s high Infra Red reflectivity on for plastic welding instruments and for optic mirrors.

Our capabilities include plating on Aluminum, Brass, Copper, Steel, Stainless Steel, and on most Non-Magtetic Alloys (Chrome & Nickel Alloys).

We are conveniently located in Houston, Texas and provide service throughout the US.

Industrial Service Offered

  • 2 – 3 Days Turn-around on most orders
  • Expedited Services Available, including same day turn-around.
  • “24 Karat” Hard or soft Acid Gold
  • Highly corrosion resistance, providing excellent conductivity, long lasting solderability
  • Nickel hardened to provide excellent wear resistance and high hardness, Tarnish resistance, even at high temperature applications
  • The process method is determined by the size, shape and volume of the item requested for plating. At times, a small batch is recommended for plating to determine the best possible method prior to plating an entire batch.
  • Gold plating on Aluminum, copper alloys, beryllium copper, brass, nickel alloys, stainless steel alloys, and steel alloys.
  • Rack Plating – For intricate shapes, including molded contacts, connectors, rotatable connectors, ground springs, and selective plating.
  • Barrel Plating – for high volume of contact pins, small contact rings, and various small size parts.
  • Vibratory Plating – For highest quality on contact pins, contact rings, and various small size parts. This method includes best distribution and coverage, including difficult to plate inside wall of small bores.
  • With our process line, we are able to process over 1 million parts per month. In house X-Ray machine for precise thickness testing

Quality Control

We specialize in providing our customers with thickness specific coatings. We hinge in understanding the engineering behind the coating call out, therefore we ensure our coating deposit is verified and certified to the customer’s requirement. Our inspection process includes an XRF coating thickness analysis (nondestructive), as well as adhesion tests, both compliant to world known specifications, including ASTM, Military, AMS, and ISO.
