OEM Brass Sand-Casting Bronze Foundry

Brief Introduction to the Product

Qingdao Chifine Machinery Co., Ltd. focuses on OEM brass sand casting and bronze foundry services for machinery parts, delivering tailored solutions to global clients. Our product range centers on brass, bronze, and copper cast components—such as water pump impellers—with strict adherence to international standards including DIN, ASTM, BS, and JIS. We streamline the entire production cycle, covering casting, deburring, machining, surface treatment, and packaging, to fully align with customer drawings, samples, or specific design demands.

Key Features of the Product

Extensive Material Options: We operate an independent copper, brass, and bronze melting factory, allowing customers to select from a wide range of alloys to match diverse machinery performance requirements.

High-Efficiency Production: Equipped with CNC machining equipment, we boost productivity while maintaining precision, supporting both small-batch prototypes and large-scale mass production.

Proven International Experience: With 20 years of cooperation history with foreign partners, we have in-depth insights into global market needs and strict quality benchmarks.

Rigorous Quality Assurance: Our dedicated QC team implements a three-step inspection process—workshop preliminary checks (to resolve issues promptly), professional standard-based testing, and pre-packaging rechecks—to eliminate any potential defects.

Customizable Surface Treatment: Options include sand blasting, anodizing, powder coating, electrophoresis paints, and dearomet treatment, tailored to enhance corrosion resistance, aesthetics, or functional performance.

OEM Brass Sand Casting Bronze Foundry for Machinery Part – Scenario-Specific Applications

Automotive Sector Application

We supply high-precision brass/bronze water pump impellers and valve parts, designed to maintain stable fluid flow and wear resistance under the high-temperature conditions of automotive engines. The corrosion-resistant properties of bronze ensure long-term reliability even in engine compartments with frequent temperature fluctuations.

Railway & Marine Industries Application

For railway braking components and marine propeller accessories, we use corrosion-resistant bronze alloys paired with shot blasting surface treatment. This combination withstands harsh outdoor or saltwater environments, reducing maintenance frequency and extending the service life of parts in railway and marine machinery.

Medical & Architectural Fields Application

Medical equipment parts require ultra-high precision and hygiene; we leverage CNC machining (with 0.01mm tolerance where applicable) and polishing to meet strict medical standards. For architectural and furniture parts, we offer customizable powder coating colors to match design aesthetics, ensuring parts blend seamlessly with indoor or outdoor spaces.

OEM Brass Sand Casting Bronze Foundry for Machinery Part – Technical Backup

Design Collaboration Support

We accept 2D/3D customer drawings and samples, using software like AutoCAD and Solidworks to optimize designs. Our engineering team analyzes casting feasibility, adjusts structural details to reduce material waste, and provides design suggestions to lower production costs while ensuring part performance.

Advanced Production Equipment

Our production line includes sand mixing machines for consistent sand quality in casting, shot blast chambers for surface finishing, and CNC lathes for precision machining. This equipment combination ensures stable casting quality, smooth part surfaces, and accurate dimensional control for every machinery part.

Flexible Quality Inspection

In-house or third-party inspection is available based on customer requirements. We use tools such as hardness testers to verify material hardness, dimension gauges to check part precision, and chemical analyzers to confirm alloy composition, ensuring all products meet pre-agreed quality standards.
