Investment casting, a method steeped in tradition yet advanced by modern technology, stands out in the field of metalworking. Stainless steel investment casting stands out as an art form that embodies precision, versatility, and utmost significance in crafting top-notch commercial products, particularly within the door hardware industry. With its ability to meet complex design requirements, investment casting is an indispensable tool for manufacturers seeking excellence.
What is Investment Casting?
Investment casting, also known as lost wax casting, is a meticulous process that involves creating a detailed wax model of the desired part, which is then encased in a ceramic shell. Once the shell hardens, the wax is melted away, leaving a cavity into which molten stainless steel is poured. After solidification, the shell is broken away, revealing a high-precision metal part. This method is renowned for its ability to produce components with intricate geometries and excellent surface finishes.
The State-of-art in Investment Casting
Stainless steel investment casting’s design and manufacturing facilities have mastered the art of investment casting, particularly in crafting innovative commercial door hardware. By integrating all critical operations, these investment casting hinges efficiently meet the specific needs of customers, delivering prompt and effective solutions. As an ISO9001-certified manufacturer, the casting door hinges are subjected to rigorous in-house and UL-certified testing, based on SGS evaluation criteria, ensuring consistent quality and reliability.
Maintaining High-Quality Standards
The stainless steel products are designed to perform exceptionally well in harsh coastal commercial environments, surpassing standard salt tests. The quality of stainless steel is rigorously verified through extensive salt spray testing in compliance with ASTM B117, consistently exceeding the A156.7 standard and enduring over 200 hours in a 5% salt concentration. This meticulous approach ensures that every product maintains a consistent and stable ratio of high-quality 304 and 316 stainless steel.
