machining castings

Product Name: Stainless Steel Casting & Machined Assembly / Precision Casting Assembly

Overview
Our stainless steel casting and machined assemblies combine two precision components manufactured through investment casting, followed by CNC machining and final assembly. Engineered for applications demanding high dimensional accuracy and pressure integrity, these assemblies are rated to withstand 1 MPa without leakage. With extensive experience in pressure-containing components, we utilize ProCAST casting simulation to validate process design before production, ensuring optimal material distribution, directional solidification, and defect-free castings. Each assembly undergoes 100% air pressure testing to guarantee reliable performance in the field.

Key Features

· Material: High-quality stainless steel (304, 316L, or customer-specified) with full material traceability
· Process 1 – Investment Casting: Precision lost-wax casting delivers complex geometries, smooth surface finish, and tight dimensional tolerances — ideal for intricate component features
· Process Validation: ProCAST casting simulation platform used to optimize gating/riser design, predict solidification behavior, and minimize porosity risks before tooling fabrication
· Process 2 – CNC Machining: Post-casting precision machining ensures critical mating surfaces, threads, and sealing interfaces meet exact specifications
· Assembly: Two components precisely assembled with controlled fit and alignment; fastening methods customized per design (threaded, welded, or mechanical lock)
· Pressure Rating: Designed and validated for 1 MPa (approximately 145 psi) operating pressure — suitable for fluid, gas, and hydraulic applications
· Pressure Testing: 100% air pressure testing performed on assembled units to verify leak integrity and structural reliability
· Quality Assurance: Comprehensive inspection including dimensional verification, material certification, and test records maintained for traceability

Applications

· Fluid control components (valve bodies, manifolds, connectors)
· Instrumentation and process control assemblies
· Hydraulic and pneumatic system components
· Chemical processing equipment
· Medical and pharmaceutical devices requiring sterile assemblies
· Industrial automation and sensing devices
