Manufacturing Process
At Invent Cast, we produce precision investment-cast vacuum pump impellers engineered for high efficiency, leak-proof operation, and long-term durability in demanding industrial applications.
Pattern & Mold Preparation: Precision patterns and investment molds for accurate impeller cavities.
Metal Melting & Pouring: Controlled pouring of molten alloy to ensure defect-free castings.
Cooling & Heat Treatment: Solidification followed by stress relieving or tempering for strength and durability.
Machining & Finishing: CNC machining for tight tolerances, smooth blade surfaces, and proper balance.
Inspection & Testing: Dimensional checks, NDT, mechanical and chemical tests, and final performance verification.

Testing & Compliance
We ensure every breather valve casting meets global quality and safety standards through rigorous testing and compliance checks:
Dimensional Accuracy: CMM, gauges, and precision measuring tools to verify exact impeller geometry, blade angles, and hub alignment.
Non-Destructive Testing (NDT): Dye Penetrant, X-ray, and Ultrasonic inspections to detect internal and surface defects.
Mechanical Testing: Hardness, tensile strength, yield strength, elongation, and impact resistance to ensure durability under vacuum operating conditions.
Chemical Analysis: Spectro analysis to confirm alloy composition, material integrity, and compliance with required standards.
Balance & Performance Testing: Dynamic and static balancing checks, rotational performance, and leak-proof operation under vacuum conditions.
Surface & Finish Verification: Blade smoothness, surface roughness, coating adhesion, and corrosion resistance validation for long-term reliability.
