Sand Casting Parts Series 1
Engineered for broad industrial use, our general machinable sand casting parts (Series 1) deliver a cost-effective, high-reliability solution for moderate-wear, general-purpose applications, serving agricultural machinery manufacturers, general industrial business clients, and pump & valve system suppliers. Cast from versatile ASTM A536 Grade 65-45-12 ductile iron and ASTM A27 Grade 60-30-03 carbon steel, these components feature a perfectly balanced hardness-toughness profile, combining consistent performance, exceptional machinability, and competitive pricing to meet the diverse needs of small to large-scale industrial operations. We support full OEM customization, tailoring every casting to your exact design and performance requirements.
The core advantage of our machinable ductile iron castings is their optimized balance of mechanical strength, ductility, and machinability, eliminating the need for expensive premium alloys for moderate-load applications. The ASTM A536 Grade 65-45-12 ductile iron grade delivers a tensile strength of 65ksi (448MPa), 12% elongation, and a hardness of HB 190-220, providing reliable wear resistance and impact absorption for general machinery components. The ASTM A27 Grade 60-30-03 carbon steel grade offers a yield strength of 30ksi (207MPa), 30J impact resistance, and a 60% machinability rating (compared to AISI 1018 steel), enabling cost-effective, high-speed post-casting machining for your production line.
We utilize both green sand and resin sand casting processes to support flexible production volumes, from small-batch custom orders to large-scale mass production, with a maximum part weight capacity of 500kg. Our casting process delivers a dimensional tolerance of CT12-13 (ISO 8062) for non-critical features, with an as-cast surface roughness of Ra ≤12.5μm. Optional shot blasting treatment improves surface finish to Ra ≤6.3μm, enhancing paint adhesion for corrosion protection coatings, ideal for cost-effective sand casting parts for agriculture machinery used in outdoor field conditions.
Our engineering team optimizes every casting design to minimize material waste, with optimized wall thickness ranging from 5mm to 50mm and minimal draft angles (3° to 5°), reducing material usage by 20% compared to precision casting methods. We maintain stocked inventory of common geometries including flanges, brackets, and pulleys for quick delivery, with custom modifications such as drilling and tapping available at competitive rates. These castings operate reliably across a -20°C to 300°C temperature range, suitable for both indoor and outdoor applications, with optional corrosion protection treatments for extended service life in harsh atmospheric conditions.
