Vacuum Impregnation
Titian Plating Vacuum Impregnation
Vacuum Impregnation Services
Vacuum impregnation seals porosity in metal castings by applying vacuum pressure to fill voids with durable sealants, preventing leakage and enhancing structural integrity. Titan Plating offers specialised vacuum impregnation services, delivering high-quality results with a focus on rapid turnaround to meet your project deadlines. Our advanced processes ensure reliable performance for components across various industries, complementing electroplating for optimal surface protection.
Vacuum Impregnation in Electroplating
Vacuum impregnation addresses porosity in castings caused by gas bubbles during solidification, which can lead to leaks under pressure. By sealing micro and macro voids with sealants, it prepares surfaces for electroplating, ensuring uniform coatings without defects. This process maintains the casting's appearance and structure, making it essential for high-pressure applications where electroplating provides additional corrosion protection.
Benefits of Vacuum Impregnation
Vacuum impregnation offers several advantages:
-
Leak Prevention: Seals voids to eliminate pressure leaks, enhancing reliability.
-
Cost Savings: Reduces scrap and waste by salvaging porous castings.
-
Extended Tool Life: Improves durability in high-stress environments.
-
No Structural Change: Maintains casting dimensions and appearance.
-
Complements Electroplating: Ensures smooth surfaces for even, adherent coatings.
Applications of Vacuum Impregnation
Vacuum impregnation is used in various applications:
-
Metal Castings: Seals porosity in engine blocks and valves for pressure integrity.
-
Powdered Metals: Fills voids in sintered parts for enhanced strength.
-
Over-Moulded Components: Prevents leakage in cables and electronics.
-
Graphite Parts: Improves pressure resistance in industrial tools.
-
Pre-Electroplating Preparation: Ensures defect-free surfaces for uniform plating.
Industries Using Vacuum Impregnation
Titan Plating provides vacuum impregnation for diverse industries:
-
Automotive: For sealing engine components and transmission parts.
-
Aerospace: In preparing castings for high-pressure systems.
-
Electronics: For leak-proof over-moulded cables and housings.
-
Manufacturing: In enhancing powdered metal tools and fixtures.
-
Marine: For corrosion-resistant components in harsh environments.
Vacuum Impregnation Process
Titan Plating employs precise vacuum impregnation methods tailored to casting types:
-
Impregnation: Parts are placed in a chamber where vacuum removes air, filling voids with sealant under pressure.
-
Recovery: Excess sealant is recovered for reuse, minimising waste.
-
Washing: Residual sealant is rinsed off to maintain cleanliness.
-
Curing: Sealant is polymerised to create a durable, leak-proof seal.
Sealants include anaerobic for powdered metals, thermosetting recoverable for castings, or recyclable types. Methods vary: dry vacuum and pressure, wet vacuum, internal impregnation, or wet vacuum and pressure. Our rapid-turnaround process delivers consistent, high-quality results.
