within the first week after receiving the customer’s order. After dewaxing and burnout of the PMMA pattern, casting proceeds
using standard investment
casting practices. This rapid response workflow enables BIMAC to deliver high- quality, mission-critical pump repair castings with minimal turnaround time, without sacrificing the metallurgical or dimensional integrity required in high- performance applications. BIMAC uses Solid Cast casting simulation software to ensure optimal casting outcomes, casting the part right the first time, every time.
Infinite Alloy Combinations in Stock Another critical factor enabling BIMAC
to accelerate turnaround for expedited orders is our extensive in-house inventory of master alloys and alloying agents. This allows us to formulate virtually any alloy composition required by the customer without delay. By maintaining stock of a broad range of base metals and alloying elements, we eliminate lead times typically associated with sourcing raw materials. Within the second week of receiving
the customer’s order, BIMAC is typically able to melt the specified alloy and pour the casting. We accommodate a wide range of specifications, including standard and specialty grades such as bronze alloys, stainless steels, and high-performance superalloys to meet
the demands of various industrial applications. BIMAC operates as a high-mix, low- to-medium volume foundry, capable of producing complex castings across a broad material spectrum. Commonly cast alloys for pump components include: • CA6NM, a low-carbon martensitic stainless steel with excellent mechanical properties, fracture toughness, cavitation resistance, and weldability. Ideal for high- stress, corrosive environments.
• WCB, a medium-carbon cast steel frequently used in pressure containing applications such as
