Maximising Investment Casting Potential with Secondary Operations

Secondary operations play a pivotal role in enhancing the capabilities and versatility of investment casting processes. While investment casting itself excels in creating intricate and complex geometries, the integration of secondary operations introduces several additional benefits. 

Comprehensive machining and casting solutions

Not every machine shop possesses the expertise to effectively machine a casting, just as not every investment caster is proficient in machining. Signicast recognises this challenge and has established a dedicated in-house machining team alongside our investment casting engineering team, collaborating closely during product launches and the qualification process to ensure the development of the most durable and consistent end products. This collaboration enhances casting features for improved machine performance and advances our casting capabilities to minimise machining allowance, reducing time and costs.  

Functional modifications

Secondary operations allow for drilling, tapping and other processes to create functional features such as holes, threads and slots that may not be feasible during the initial casting process. These operations include straightening and coining, offering a cost-effective alternative to traditional CNC machining and providing a more economical option for controlling the position and flatness of specific features.

Improved surface finish

Secondary operations such as tumble polishing, media blasting and more can remove surface imperfections such as parting lines, flash and minor casting defects. These processes address these issues while also improving the surface finish grade, reducing the need for costly manual polishing operations. By using more automated processes, they streamline production and ensure that components efficiently meet their functional requirements.

Enhanced dimensional accuracy

While investment casting offers tight tolerances, secondary machining can achieve even greater dimensional accuracy for critical features. This is especially beneficial for parts requiring precise fits or interfaces with other components.

Secondary operations serve as indispensable complements to investment casting processes, amplifying their capabilities and refining end products. From comprehensive machining solutions to functional modifications, these operations enhance dimensional accuracy, optimise surface finish and improve functional features. The integration of investment casting and secondary operations opens the door to endless possibilities, advancing industries with unparalleled quality and performance.

Signicast helps to scale up production, exceed diverse project requirements and maintain consistent quality standards. The company excels in seamlessly managing sudden increases in demand, giving it a competitive edge in the casting industry.
