Large-Scale Volute Castings for Industrial Compressors

A success use case from our trusted partner Sichuan Y&J Industries Co., Ltd.—the successful delivery of a 10-tonne+ volute casting for an industrial compressor application.

This project exemplifies the level of engineering rigour, process discipline, and quality control required to manufacture large, high-integrity pressure components for critical industrial service.

End-to-End Manufacturing Excellence

The volute casting was delivered through a fully integrated manufacturing process, including:

• Pattern design and large-scale casting

• Precision machining of critical interfaces

• Assembly and fit-up verification

• Pressure testing and dimensional validation

• Surface preparation and industrial coating

Each stage was executed under strict quality control procedures, incorporating chemical, mechanical, and non-destructive testing (NDT) to ensure full compliance with specification and service requirements.

The result was an on-time delivery of a complex, heavy-section component manufactured to a consistently high standard—meeting both performance and reliability expectations.
