Ningbo Nord Machinery Co., Ltd. produces custom alloy steel castings using the water glass precision casting process, which enables high dimensional accuracy and fine surface finish. The material is typically AISI 4140 or equivalent low-alloy steel, with carbon content between 0.38% and 0.45%, and chromium, molybdenum, and manganese for enhanced strength and hardenability. Castings are produced to client drawings with tolerances as tight as ±0.1 mm for critical dimensions.
The water glass process uses a silica-based slurry to form the mold, allowing for complex geometries and thin walls down to 3 mm thickness. Surface roughness typically ranges from Ra 3.2 to 6.3 μm, reducing the need for secondary machining. Post-casting heat treatment includes normalizing and tempering to achieve hardness levels of 22 to 28 HRC, depending on application. This method is preferred over sand casting for parts requiring tight tolerances and minimal machining allowance.
These castings are used in valve bodies, pump housings, hydraulic components, and industrial machinery parts for OEM manufacturers in automotive, oil and gas, and heavy equipment sectors. Buyers typically order in batches of 50 to 500 units per design, with lead times of 30 to 45 days from drawing approval. Packaging includes rust-inhibiting oil coating and individual plastic wrapping inside wooden crates. Shipping is offered under FOB Ningbo or CIF terms, with payment via L/C or T/T.

Verify the exact steel grade, chemical composition, and heat treatment parameters before ordering. Request a material test report (MTR) and hardness test results for each batch. Do not accept generic claims like 'high-strength steel' - demand certified data matching ASTM A29 or ISO 683-1 standards. Confirm that the supplier can produce to your drawing revision level.
Lead time is typically 30 to 45 days from approved drawings. Confirm Incoterms - FOB Ningbo is standard, but CIF requires insurance documentation. Payment is usually 40% advance and 60% against BL copy via L/C. Avoid full prepayment. Ensure the contract includes penalties for dimensional deviations exceeding agreed tolerances.
Conduct a pre-shipment inspection for surface finish, dimensional accuracy, and internal integrity. Request ultrasonic or radiographic test reports for pressure-rated components. Check for surface porosity, cold shuts, or misruns. Ensure packaging includes rust inhibitor and moisture barriers. Retain inspection photos and certificates for customs and warranty claims.
