As one of Australia’s leading engineering firms, Leussink has worked with a range of defence contractors, Government contractors and blue chip manufacturing companies across Australia.

Based in the heart of the Illawarra, Leussink provides a range of manufacturing and engineering services at our state-of-the-art facility. From bespoke engineering, design and project management, through to prototyping, CNC machining, metrology solutions and welding & fixturing solutions, Leussink services not only defence industry, but also the manufacturing & heavy industrial sector, the mining sector, and science based industries.

From humble beginnings in 1977, Leussink has grown to become a world-leading manufacturer of engineering solutions for clients across the world. Our reach has extended into international markets including Europe, Asia, UAE and New Zealand.

Leussink collaborates with a wide range of businesses based in various industries to improve efficiency, quality, productivity and by extension, profitability. Leussink is able to deliver on these requirements through the support of our key partners and our own ability in providing in-house bespoke engineering services, such as creating one-off parts.

Leussink partners with, Demmeler Corporation (Germany) to provide high-quality, tailored modular fixturing solutions, Tomelleri Engineering (Italy) to provide world-leading portable metrology solutions, and US based firm ALM Positioners to provide a range of engineered positioners that allow for 360° welding of oversized components safely and ergonomically.

Leussink’s ‘think solve engineer’ motto is part of our core values and helms our partnership with customers. For example, a large steel manufacturer based on the east coast of Australia, approached Leussink to problem solve why their cast-iron impellers, designed to circulate saltwater through their plant to cool equipment, were consistently experiencing reduced Mean Time Between Failure. Lacking any existing designs or moulds for the impeller, coupled with the complexity and tight timeframe for delivery, the challenges for Leussink were numerous.

In order to troubleshoot and understand the problem, Leussink employed its Tomelleri Portable Metrology solution, which resulted in the part being reverse engineered through 3D modelling to replicate its working environment. This led Leussink to discovering several design issues, one of which was that only one of the impeller’s five blades were operating efficiently. Leussink then recommended a solution to craft an impeller from a single piece of stainless steel providing an alternative part that was built stronger, lasted longer and was far more efficient than the OEM design.

Leussink also has extensive experience in providing high-quality, tailored manufacturing solutions for businesses and industries where accuracy and precision are top priorities. A Western Australian shipbuilder, defence prime contractor and maritime technology business identified inadequacies and inefficiencies in their pipe spool production processes and operations.

Working in collaboration with the customer, the team at Leussink designed and created a Demmeler modular fixturing solution that would meet Austal’s objectives. With the modular set up of the Demmeler table system, the customer no longer needed to break the pipes down into small sections. The versatile layout of the table system allowed the customer to work on larger sections of pipe at a time, which greatly increased accuracy and turnaround time.

Leussink believes in the importance of knowing and understanding a customer’s business, as well as their objectives and requirements. By doing this Leusssink are able to design and create the best solutions in order to exceed expectations.
