Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer specializing in custom machining for automotive engine parts. Since our establishment in 2022, we have rapidly grown into a trusted partner for global clients, with a factory spanning 10,000–30,000 square meters and an annual export value exceeding US$2.5 million. Our expertise lies in precision machining of 45# steel components with a hardness of HRC 50, ensuring exceptional durability and performance in demanding automotive environments. Leveraging advanced CNC equipment, strict quality control, and a team of 51–100 skilled employees, we deliver parts that meet the most stringent specifications.
This product line is designed for automotive engine systems where reliability, heat resistance, and wear life are critical. 45# steel (medium carbon steel) is chosen for its excellent balance of strength and machinability, while the HRC 50 hardness level provides superior resistance to deformation under high stress. Whether you need crankshafts, connecting rods, camshafts, or custom engine blocks, our capabilities allow us to produce high-precision custom parts with tight tolerances and complex geometries. Below we detail the key features, technical specifications, and benefits of our service.
Key Features & Technical Specifications
- Material Excellence: 45# steel (equivalent to AISI 1045) offers high tensile strength (≥600 MPa) and good hardenability. After heat treatment, hardness reaches HRC 50, ensuring a long service life under cyclic loading.
- Precision Machining: Our CNC lathes, milling machines, and grinding centers achieve tolerances as tight as ±0.005mm, with surface roughness down to Ra 0.8 μm. This ensures perfect fit and function in engine assemblies.
- Customization Flexibility: We accept designs from customer drawings (2D/3D) or samples. Part size range from 10mm to 800mm diameter, weight up to 200 kg. Complex features like internal oil passages, threaded holes, and keyways are standard.
- Heat Treatment & Hardness Control: Quenching and tempering processes are precisely controlled to achieve uniform HRC 50 hardness across the part. We provide a hardness test report with each batch.
- Quality Assurance: Every part undergoes 100% inspection using CMM, optical comparators, and hardness testers. We are certified under ISO9001, ISO14001, OHSAS18001 and follow strict quality management systems.
- Surface Finish Options: As required, we offer black oxide, phosphating, nickel plating, or oil coating to improve corrosion resistance and aesthetic appearance.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for custom machining of engine parts?
A: Our MOQ is 1 piece for prototypes and 100 pieces for production, but we can be flexible based on the complexity and size. Please contact us for a specific quote. -
Q: Can you machine parts with hardness higher than HRC 50?
A: Yes, we can handle materials up to HRC 60 using specialized carbide tools and grinding processes. However, 45# steel at HRC 50 offers an excellent balance of strength and machinability for most engine applications. -
Q: Do you provide heat treatment services?
A: Yes, we offer in-house heat treatment (quenching and tempering) to achieve the required hardness. We also provide third-party hardness testing reports if needed. -
Q: What file formats do you accept for drawings?
A: We accept STEP, IGES, STL, DXF, DWG, and PDF. For complex parts, 3D models are preferred. We can also reverse engineer from physical samples. -
Q: How do you ensure the quality of each batch?
A: We follow a strict quality plan: incoming material inspection, in-process inspection (first article, SPC), and final inspection with CMM, hardness tester, and surface roughness gauge. A certificate of compliance is issued with each shipment. -
Q: What is the typical lead time for a custom engine part?
A: For prototypes, 10–15 working days. For mass production (100–1000 pieces), 20–30 working days. Rush orders can be expedited for an additional fee. -
Q: Can you provide surface treatment like blackening or phosphating?
A: Yes, we offer black oxide, phosphating, nickel plating, and oil coating. Please specify your requirements, and we will recommend the best option for protection and appearance. -
Q: Do you ship internationally? What ports do you use?
A: Absolutely. We ship worldwide via sea, air, or express. Our main ports are Shanghai, Qingdao, Tianjin, and Lianyungang. We have experience with customs clearance in many countries.
