Heat Treatment Baskets Dedicated to Auto Parts

Optimized Design for Batch Processing of Gears and Bearings

Auto parts such as gears and bearings are core components of vehicle transmission systems, requiring high-precision heat treatment to ensure wear resistance, fatigue strength and dimensional stability. Traditional heat treatment fixtures have drawbacks like low batch loading efficiency, uneven heating and easy workpiece collision, which restrict the production capacity and quality consistency of auto parts manufacturers.
FH’s heat treatment baskets dedicated to auto parts are independently developed for the characteristics of gear and bearing batch processing, with targeted structural optimization to meet the high-efficiency, high-quality heat treatment needs of auto parts production lines.

Core Optimization Design for Gears & Bearings
1. Grid Partition Structure: Prevent Collision and Ensure Uniform Heating

• The basket interior adopts a customized grid partition design based on the outer diameter and thickness of gears/bearings. Each grid is precisely matched to the size of a single workpiece, effectively avoiding collision, extrusion and deformation of workpieces during loading, heating and cooling.
• The grid partition is made of high-strength heat-resistant steel alloy, with a hollowed-out design at the bottom and side walls to maximize heat radiation penetration, ensuring uniform heating of the inner and outer surfaces of gears and bearings, and reducing the risk of quenching deformation.

2. High-Load Stackable Design: Improve Batch Processing Efficiency

• A reinforced edge and stacking positioning groove structure is added to the basket body, which can realize stable stacking of multiple layers of baskets in the furnace. The stacking height can be customized according to the effective space of the vacuum furnace, increasing the single-furnace loading capacity by 30%–50% compared with traditional fixtures.
• The overall load-bearing capacity is optimized by adding reinforcing ribs at key stress points. The basket can bear the weight of batch gears/bearings without deformation at high temperatures (≤1200℃), adapting to the continuous batch production rhythm of auto parts manufacturers.

3. Material Customization: Adapt to Different Heat Treatment Processes

• For carbon-neutral heat treatment processes (such as gear carburizing and quenching): Adopt low-carbon heat-resistant steel alloy, strictly control the carbon content of the material to avoid carbon pollution to workpieces, and ensure the accuracy of gear carburizing layer depth.
• For high-temperature tempering processes: Select heat-resistant steel with excellent creep resistance, which can maintain structural stability for a long time under high-temperature holding conditions, and avoid basket deformation affecting workpiece positioning accuracy.
• For vacuum quenching processes: Optimize the surface roughness of the basket to enhance thermal radiation performance, and match the thermal expansion coefficient of gears/bearings to reduce thermal stress between the basket and workpieces during rapid cooling.

4. Easy to Clean and Maintain: Reduce Production Auxiliary Time

• The basket surface is treated with high-temperature anti-oxidation coating, which can effectively prevent oxide scale adhesion during long-term use. After each furnace run, it can be quickly cleaned with a high-pressure air gun or wire brush, reducing cleaning time by more than 20%.
• The detachable grid partition design is adopted for large-size gear baskets, which is convenient for local replacement of damaged partitions, reducing maintenance costs and extending the overall service life of the basket.
