By combining casting, forging, CNC machining, and related surface electrophoretic coating where applicable, SITC supports customized component production with improved consistency, traceability, and production management.
CNC machining for castings is commonly used when a cast component needs accurate functional areas after the foundry process. SITC supports machining for ductile iron castings, gray iron castings, and steel castings. Final suitability depends on part design, material requirements, and application conditions.
Typical features may include mounting faces, threaded holes, through holes, slots, grooves, locating surfaces, sealing surfaces, bearing seats, and assembly interfaces. Feasibility, tolerances, and surface requirements are confirmed based on the customer’s drawing and technical specification.
Forged components often provide strength and performance advantages. CNC machining is usually required to create final connection geometry and functional surfaces. SITC supports precision machining for steel forgings and aluminum forgings after forming. This helps buyers obtain components that are ready for assembly or further finishing.
Machined forgings may require controlled dimensions for holes, edges, faces, slots, profiles, and connection points. The suitable process depends on the forging material, product structure, batch quantity, and performance requirements.
