Sand-Cast Gray Iron Agricultural Machinery Parts | Durable & Precision for Farming Equipment
With over 10 years of experience as an integrated manufacturing and foreign trade enterprise, we specialize in producing high-quality sand-cast gray iron agricultural machinery parts. As core components for farming equipment, our sand-cast gray iron parts are engineered to deliver exceptional durability, dust resistance, and load-bearing capacity—tailored for the harsh outdoor conditions of plowing, sowing, harvesting, and irrigation. Serving global B2B clients including agricultural machinery manufacturers, farming equipment distributors, and regional agricultural cooperatives, we provide consistent quality backed by international certifications, professional technical support, and seamless global logistics solutions that meet Western market standards.
Why Sand-Cast Gray Iron for Agricultural Machinery Parts?
Sand casting combined with gray iron material forms an optimal solution for agricultural machinery parts, perfectly matching the industry's demand for cost-effectiveness and reliability:
• Superior castability of gray iron: Sand casting efficiently shapes complex structures (e.g., gear boxes, bearing housings) required for agricultural machinery, reducing production costs for large-batch orders.
• Excellent wear resistance: Gray iron’s graphite flake structure provides natural lubricity, extending service life of parts subject to frequent friction (e.g., transmission shafts, conveyor components).
• Strong environmental adaptability: Withstands soil moisture, dust, and temperature fluctuations in outdoor farming scenarios, avoiding rust and functional failures.
• Cost-effectiveness: Sand casting enables mass production with lower tooling costs, while gray iron is economically efficient, supporting competitive pricing for agricultural equipment manufacturers.
We exclusively adopt high-quality sand-cast gray iron grades (HT200, HT250) that meet ISO 185 standard, with full Material Test Certificates (MTC) provided for each batch to ensure traceability and material reliability.
Core Production Process: Sand Casting & Supplementary Technologies
Our production process centers on precision sand casting, supplemented by advanced machining and surface treatment technologies to ensure part quality and performance. The visualized workflow is as follows:
1. Certified Gray Iron Sourcing & Pre-Inspection: Raw gray iron is sourced from ISO-certified suppliers. We conduct strict chemical composition analysis and Brinell hardness testing to eliminate impurities and ensure material uniformity.
2. Precision Sand Casting: Adopt resin sand casting technology—high-purity resin sand ensures mold stability, reducing casting defects (e.g., sand holes, shrinkage). Mold design is optimized based on part structure to ensure uniform wall thickness and accurate dimensioning.
3. Deburring & Cleaning: Remove casting burrs and sand residues via mechanical grinding and shot blasting, ensuring surface smoothness and avoiding assembly interference.
4. Heat Treatment: Normalization process to reduce internal stress, improve material toughness (HB 170-220), and prevent deformation during field operation.
5. Precision CNC Machining: Equipped with 20+ sets of CNC lathes and milling machines to process key surfaces (mating surfaces, thread holes, shaft journals) with high precision, ensuring seamless assembly with other components.
6. Targeted Surface Treatment: Custom processes including anti-rust epoxy painting, phosphating, and black oxide treatment to enhance outdoor corrosion resistance. All treatments comply with RoHS standards.
7. Multi-Stage Quality Testing: 100% dimensional inspection via Coordinate Measuring Machine (CMM); magnetic particle flaw detection for internal defects; and assembly compatibility testing with mainstream agricultural machinery models. Only qualified products are shipped.
8. Secure Packaging & Global Shipping: Anti-collision foam + wooden crate packaging to protect parts during long-distance transportation. Partner with DHL, FedEx, and Maersk to provide delivery to 150+ countries, with complete customs clearance documents (commercial invoice, certificate of origin, MTC).
Supplementary processes such as welding (for component assembly), dynamic balance testing (for rotating parts), and custom drilling are available to meet specific requirements of agricultural machinery manufacturers.
Common Sand-Cast Gray Iron Processing Challenges & Solutions
Based on years of experience in sand-cast gray iron agricultural parts production, we have targeted solutions for industry-specific processing pain points:
Common Challenges | Targeted Solutions | Effectiveness |
Sand holes in sand-cast parts affecting sealing performance (e.g., pump bodies) | Optimize resin sand particle size and compaction density; add filter screens in the pouring system; conduct 100% X-ray flaw detection for sealed components | Sealed component defect rate reduced to ≤0.35% |
Rough surface of sand-cast parts increasing wear | Upgrade shot blasting process (high-pressure steel shot); add fine grinding for key friction surfaces; optimize sand mold surface treatment | Surface roughness of key surfaces reduced to Ra≤1.6μm |
