Our Story
PP Shim Co’s roots go back to 1981, when Gerhard Blaschka, a qualified Toolmaker with a passion for precision engineering, founded Promet Products. Operating from his Sydney workshop, Gerhard manufactured dies for high-quality Welch plugs and associated components. His reputation for quality craftsmanship quickly attracted major clients, and the business grew rapidly.
But the real turning point came in 1995. Recognising an opportunity to specialise, Gerhard sold the Welch plug division and acquired Wildash Shim Co, one of Australia’s established shim suppliers. It was a bold move, trading a successful general manufacturing business for a focused niche, but it proved to be the right one. PP Shim Co was born, and with it came a singular mission: to become Australia’s most comprehensive and reliable shim supplier.
That mission has guided everything since. In 2000, founding directors Gerhard Blaschka, Bill Code, and Ingrid Code retired. Gerhard’s son, Robert, and nephew, Peter Code, stepped into leadership, bringing fresh energy and a clear vision for growth. Under their stewardship, PP Shim Co has expanded its product range, invested in custom-cutting capabilities and quality control infrastructure, and established itself as Australia’s go-to shim supplier across multiple industries.
