Full Spectrum of OEM Precision Cast Parts
We manufacture OEM precision cast parts fully customized to your 2D/3D drawings, covering the complete product lines shown in our product catalog:
1. Precision Hardware & Structural Cast Parts
Our small-format OEM precision cast parts (as shown in our first product image) include custom brackets, connectors, fasteners, and special-shaped structural components for industrial equipment and consumer hardware. Manufactured via precision investment casting, these parts feature complex geometries, smooth surface finishes, and consistent tight tolerances, eliminating the need for excessive secondary machining and reducing your overall production costs.
2. Sand Cast Pump & Fluid Handling Parts
The ductile iron and gray iron pump body castings are our core OEM precision cast parts for fluid handling industries. As shown in our product photo, the single-piece cast pump volute is engineered with optimized internal flow channels, delivering superior hydraulic efficiency and zero leakage performance for industrial water pumps, chemical transfer pumps, and fire safety systems. All pump cast parts undergo 100% hydraulic pressure testing to ensure long-term reliable operation in harsh working environments.
3. Die Cast Aluminum Thermal & Functional Parts
Our aluminum die cast OEM precision cast parts include heat sinks, turbine housings, and mounting brackets shown in our product catalog. Manufactured via high-pressure die casting, these parts feature thin-wall capabilities (minimum 0.8mm), excellent thermal conductivity, and high dimensional consistency, making them ideal for electronics thermal management, small engine systems, and automotive lightweight components.
4. Engine & Transmission Housing Cast Parts
The automotive powertrain housing castings are our high-demand OEM precision cast parts for passenger vehicles, motorcycles, and off-road equipment. The die cast engine and transmission housing shown in our product image is designed with integrated mounting points, oil channels, and reinforcement structures, delivering exceptional structural rigidity and vibration resistance. All automotive cast parts are produced in full compliance with IATF 16949 automotive industry standards.
Casting Processes Tailored to Your Parts
We offer 3 core casting processes optimized for the design, volume, and performance requirements of your OEM precision cast parts:
- Investment Casting (Lost Wax Casting): Perfect for small, complex OEM precision cast parts with tight tolerances and smooth surface finishes (Ra1.6-Ra3.2), ideal for stainless steel hardware and special-shaped structural components with no draft angle requirements.
- Sand Casting: Cost-effective solution for medium-to-large size OEM precision cast parts, such as pump bodies, valve housings, and heavy structural components, supporting single-piece castings up to 1000kg with fast tooling turnaround.
- High-Pressure Die Casting: High-efficiency process for mass production of aluminum and zinc alloy OEM precision cast parts, with cycle times as low as 45 seconds per piece, suitable for heat sinks, automotive housings, and high-volume hardware components.
Material & Surface Finish Options
We support full material and finish customization for your OEM precision cast parts, with full material certification for every production batch:
- Ferrous Materials: Ductile iron (QT400-18, QT500-7), gray iron (HT200, HT250), carbon steel (WCB, A105), stainless steel (CF8, CF8M, 304, 316)
- Non-Ferrous Materials: Aluminum alloy (A380, ADC10, A356), zinc alloy, copper alloy, and heat-resistant superalloys for high-temperature applications
- Surface Finishes: Shot blasting, powder coating, anodizing, passivation, zinc plating, precision polishing, and Teflon coating, fully customizable to match your corrosion resistance and aesthetic requirements.
Defect-Free Quality Control System
Our 4-tier quality management system ensures every batch of OEM precision cast parts meets your exact specifications, with zero defects leaving our factory:
- Pre-Production Defect Prevention: Mold flow simulation and material composition testing before production, to eliminate porosity, shrinkage, and dimensional deviation risks for your cast parts.
- In-Process Real-Time Monitoring: 100% first article inspection via CMM, with periodic sampling and non-destructive testing (NDT) during production to maintain consistent tolerance control.
- Targeted Performance Testing: Hydraulic pressure testing for pump parts, hardness testing for structural components, and leak testing for sealed housings, tailored to the functional requirements of your OEM precision cast parts.
- Final Pre-Shipment Validation: Full dimensional, visual, and packaging inspection before shipment, with a detailed quality report included with every order for full traceability.
Flexible OEM Support for All Order Sizes
We provide end-to-end OEM support for your precision cast parts, no matter the project scale:
- DFM Optimization: Our engineering team provides design for manufacturability feedback to reduce production costs, shorten lead times, and improve component performance, without compromising your design intent.
- Rapid Prototyping: 2-4 day prototype turnaround via 3D printed wax patterns and rapid tooling, allowing you to validate fit, form, and function before investing in mass production tooling.
- Flexible Production: We support production runs from 10-piece prototype batches to 1,000,000+ piece mass production orders, with dedicated production lines for high-volume OEM projects.
- In-House Secondary Operations: 5-axis CNC machining, thread tapping, assembly, and custom packaging, providing a one-stop solution to eliminate the need for multiple suppliers.
