Custom High-Strength Spring Shield for Auto Reset Shank

1. Product Overview

Our heavy-duty Spring Shield for Auto Reset Shank is engineered to provide critical protection for the auto-reset mechanisms of cultivator shanks in harsh soil environments. Precision-cast from premium 52CrMnMoV alloy steel using investment casting, this component combines exceptional wear resistance with superior structural integrity. The robust cylindrical design guarantees that your tillage equipment operates reliably, significantly reducing maintenance costs and downtime when facing hard, rocky soils or high-frequency impact vibrations.

3. Key Features

• Unbreakable Structural Integrity: The contoured design features 8mm reinforcement ribs, which, combined with the 52CrMnMoV alloy steel, allows the shield to withstand instantaneous impact forces up to 6,500 lbs.
• Optimized Debris Deflection: Engineered with a precision 30° deflection angle, it effectively redirects soil, rocks, and crop residue to prevent jamming while maintaining complete structural stability.
• Seamless High-Precision Installation: CNC-machined to ensure mounting hole tolerances are kept strictly within ±0.05mm. Verified by CMM (Coordinate Measuring Machine) to guarantee a 100% perfect fit for your equipment.
• Military-Grade Corrosion Resistance: Surface treatments include MIL-SPEC shot blasting (SAE J444) for optimal paint adhesion. An optional Dacromet® coating is available, providing 1,500+ hours of salt spray resistance in highly corrosive environments.

4. Rigorous Manufacturing & Heat Treatment

To achieve ultimate physical performance, each spring shield undergoes an industry-leading heat treatment regimen:

1. Normalizing: Conducted at 900-920°C to ensure a uniform grain structure.
2. Annealing: Applied for internal stress relief from the casting process.
3. Oil Quenching: Quenched at 850°C to significantly increase material hardness.
4. Tempering: Processed at 540-600°C to achieve the perfect balance of toughness and hardness (HRC 32-36), preventing brittle fractures.

5. Applications & Compatibility

• This component is critical for heavy-duty cultivators, subsoilers, and chisel plows.
• Broad Compatibility: Directly replaces and seamlessly fits leading market models, including the John Deere 2210 series and Case IH 3300 series.
• Extreme Environment Ready: Maintains stable mechanical performance whether operating in freezing permafrost (-40°C) or high-load, continuous-use heat (+120°C).

6. Buyer’s Guide & Sourcing Notes

• Surface Treatment Selection: Our standard finish is an anti-rust black baking varnish. If your target market is in high-humidity or coastal saline-alkali areas, we highly recommend selecting the Dacromet® coating version.
• OEM & Customization: We support secondary development and non-standard customization based on client drawings, including custom engraved corporate logos.
• Packaging & Logistics: As a heavy-duty metal casting, the products are packed in marine-grade reinforced pallets with anti-rust wrapping to ensure safe cross-border transit.

7. Industry & Buyer FAQ

Q1: Why choose 52CrMnMoV alloy steel over standard carbon steel?
A: 52CrMnMoV is a high-performance spring alloy steel. Because subsoiler shanks frequently strike hidden rocks underground, standard carbon steel is highly susceptible to plastic deformation or snapping. 52CrMnMoV provides an unmatched toughness-to-hardness balance, allowing it to absorb high-frequency vibrations and spring back to its original shape after severe impacts.

Q2: What is your quality control process?
A: Our production facilities are certified under the IATF 16949 automotive quality management system. Every batch of spring shields is subjected to:

• 180% overload testing.
• Magnetic Particle Inspection (MPI) to eliminate any micro-cracks.
• Precision CMM verification to ensure mounting hole alignment within a ±0.1mm margin.

Q3: What is the Minimum Order Quantity (MOQ) and lead time?
A: Our standard casting MOQ is typically 500-1000 pieces. The lead time for regular orders is approximately 15-30 days. For standard compatible models currently in stock, we can offer much faster dispatch times.
