Welcome to Henan San Kuang Machinery Technology Co., Ltd., a leading foundry factory established in 2014. We specialize in providing professional OEM metal casting services to a global clientele. With a sprawling 10,000-30,000 square meter facility and a dedicated team of 51-100 skilled professionals, we are committed to transforming your designs into high-quality, durable metal components. Our core value lies in delivering precision, reliability, and comprehensive solutions from prototype to mass production, backed by a robust quality management system.
Our ISO certified metal casting service is engineered to meet the stringent demands of various industries. We understand that every component is critical to your final assembly, which is why we employ advanced processes and rigorous quality control at every stage. Whether you need complex geometries, tight tolerances, or specific material properties, our foundry is equipped to handle your project with expertise. Partnering with us means gaining a reliable manufacturing extension that prioritizes your specifications, timeline, and budget.
Key Features and Technical Advantages:
- Versatile Casting Processes: We offer multiple casting methods to suit different applications, material requirements, and volume needs. This flexibility ensures optimal cost-effectiveness and part performance.
- Wide Material Selection: Cast components in various ferrous and non-ferrous metals, including carbon steel, stainless steel, ductile iron, gray iron, aluminum alloys, brass, and bronze.
- Integrated Manufacturing: Our services extend beyond casting. We provide in-house machining, heat treatment, surface finishing (painting, plating, powder coating), and assembly, offering a true one-stop solution.
- Precision and Consistency: Utilizing modern pattern-making, mold-making technologies, and process controls, we ensure dimensional accuracy and repeatability for every batch of parts.
- Engineering Support: Our technical team offers Design for Manufacturability (DFM) feedback to optimize your part design for the casting process, potentially reducing costs and improving quality.
- Stringent Quality Assurance: Every project undergoes multiple inspections, including material certification, dimensional checks, visual inspection, and Non-Destructive Testing (NDT) like X-ray or ultrasonic testing as required.
The table below outlines some of our common casting capabilities and specifications. Please note that all parameters are customizable based on your specific project requirements and technical drawings.
| Aspect | Capability / Specification |
|---|---|
| Primary Casting Methods | Sand Casting, Investment Casting (Lost Wax), Die Casting (for non-ferrous) |
| Typical Part Weight Range | From 0.1 kg to 500 kg (or higher for sand casting) |
| Standard Dimensional Tolerance | CT7 to CT9 per ISO 8062 (varies with process and size) |
| Surface Roughness (Ra) | 3.2 μm to 25 μm, improvable with machining |
| Common Wall Thickness | 3 mm to 50 mm (process and material dependent) |
| Prototype Service | Available using rapid prototyping or short-run tooling |
Benefits for Your Business:
- Cost Reduction: Casting is often more economical than machining from solid for complex parts, especially in medium to high volumes. Our efficient processes help control your unit cost.
- Design Freedom: Create intricate shapes, internal cavities, and undercuts that are difficult or impossible with other manufacturing methods.
- Material Properties: Achieve desired mechanical properties like strength, wear resistance, or corrosion resistance by selecting the appropriate alloy and heat treatment.
- Supply Chain Simplification: By consolidating casting, machining, and finishing with a single supplier, you reduce logistics complexity, communication overhead, and total lead time.
- Scalability: We support projects from single prototypes to large-scale production runs, providing consistent quality as your demand grows.
With an annual export value ranging between US$2.5 Million and US$5 Million, Henan San Kuang has established a strong reputation across major markets including North America, Europe, Southeast Asia, and beyond.

Frequently Asked Questions (FAQ)
-
Q: What information do you need to provide a quotation for a casting project?
A: To provide an accurate quote, we typically require your 2D drawings (with tolerances) or 3D CAD model (STEP, IGS format), material specification, required quantity, and any special surface finish or post-processing requirements. -
Q: Can you work with my existing patterns or tooling?
A: Yes, we can evaluate and use your existing tooling if it is in good condition and suitable for our equipment. We can also repair or modify tooling as needed. -
Q: What is your typical lead time for prototype and production orders?
A: Lead time varies based on part complexity, process, and order volume. Prototype samples can often be delivered in 2-4 weeks. Production lead times are determined after finalizing all project details. We strive to provide realistic timelines and keep you updated. -
Q: How do you ensure the quality of the cast parts?
A: Quality is integrated into our process. We perform incoming material checks, process parameter monitoring, first-article inspection, and final random or 100% inspection based on your requirements. Certifications like ISO 9001 guide our systematic quality management. -
Q: Do you offer secondary machining and assembly services?
A: Absolutely. We provide comprehensive post-casting services including CNC machining, drilling, tapping, heat treatment, and various surface treatments. We can also perform sub-assembly work, delivering ready-to-install components. -
Q: What file formats are preferred for submitting part designs?
A: We prefer 3D files in neutral formats like STEP (.stp) or IGES (.igs) along with 2D PDF or DWG drawings that clearly indicate critical dimensions, tolerances, and surface finish requirements. -
Q: What is your Minimum Order Quantity (MOQ)?
A: Our MOQ is flexible. We welcome prototype and low-volume orders for testing and development. For mass production, we discuss economical batch sizes based on tooling and setup costs. -
Q: Which industries do you primarily serve with your casting services?
A: Our components are widely used in automotive, agricultural machinery, construction equipment, mining, valve and pump manufacturing, and general industrial machinery sectors.
