VALUE PROPOSITION

As an engineering driven group, we have exceptional engineering capability and are domain experts at maximizing product lifecycles. PPG is the leading gear and machining manufacturer in its industries because we have the uncommon ability to manufacture gears and machined products that range in size from ½” to 7.4 meters (nearly touching the ceiling of our manufacturing facilities). We are recognized as the go to source for long life, high durability machined components in a wide range of size envelopes and materials, and we provide all of the data and services to verify that our products are the best.

Because of our unique technical abilities to service and meet the demanding tolerances of the Aerospace industry, we are able to apply the same rigid quality assurance protocols to all our products in all the industries served. Regardless of the size or quantity of customer orders, our environmentally controlled facilities give us the competitive advantage to quickly adjust our cells to meet tight time constraints and provide the shortest lead times possible.

Our many degreed engineers with decades of experience work together in a team matrix producing hundreds of custom gearing and machining solutions annually.

Our motto is “the tougher the part...the more we excel to solve the challenge and meet our customer’s needs.”

We thrive on manufacturing challenges and make the parts our competitors no-quote. PPG has its own in-house heat treat facility, including the largest die quenching unit* in North America with the unique capability of quenching gears up to 82 inches in diameter. As an ISO 9001 & AS 9100 compliant organization, we are able to manufacture and inspect gears up to American Gear Manufacturers Association ("AGMA") Class 15 specifications (the highest classification). We maintain excellent satisfaction ratings from our customers in many cases achieving “gold” status. A team-oriented organization, PPG employs only the best machining and gearing people in the world to service our customers.

* Die quenching provides controlled hardening in restraining dies of close tolerance internal and external gearing to ensure dimensional control as well as uniform hardening providing our customers with durable products that withstand any field application.

About

At PPG, we realize that our customers have to make choices about who to trust with their business. Our mission is to make our customers’ choices easier by continuing to improve in our ability to design, build, assemble, and test those products (and more!) and to deliver them on time with superior quality at a fair price. We work hard to earn both your trust and your business.
