Steel Pallet with Tray-mesh Basket Heat Treatment Fixtures for Annealing & Tempering

Tray-mesh Basket Heat Treatment Fixture & Toolings

The tray-mesh basket heat treatment fixture is a highly standardized and modular integrated loading unit in the tray furnace system. Combining the load-bearing frame (tray) and the workpiece container (mesh basket) into a single entity, it serves as a key component for tray furnaces to achieve efficient, flexible, and automated production.

I. Core Concepts and Structural Composition
This type of fixture typically consists of two core components, forming a "base tray+ detachable container" assembly:
1. Standard Tray Base

• Function: Serves as the basic mobile platform and core structural strength component of the entire fixture. It is a robust metal frame (usually welded from heat-resistant steel such as RA330), with integrated traveling mechanisms (wheels or sliders) at the bottom, sealing and guiding structures on the edges, and standardized positioning and locking interfaces on the top.
• Features: Perfectly compatible with the tray furnace’s track, drive, and sealing systems, responsible for precise and stable cyclic movement in the production line.

2. Interchangeable Mesh Basket

• Function: Acts as the container for directly holding, separating, and fixing workpieces. It is a hollowed-out basket welded from heat-resistant steel wire or steel plate mesh, mostly square or circular in shape.
• Features:

01. High Air Permeability: The mesh structure ensures that the heat treatment atmosphere and quenching medium fully and evenly contact every workpiece.
02. Modularity: The mesh basket can be quickly and accurately connected to or separated from the tray base via positioning pins, quick-release buckles, or bolts.
03. Specialization: Customized mesh baskets with different internal compartments and separators can be designed according to the shape, size, and process requirements of different workpieces, enabling multi-purpose use of a single tray.

II. Key Design Considerations
1. Interface Standardization

• The Key to Success.The mechanical interfaces (positioning and locking) and hoisting interfaces between the tray base and all mesh baskets must be fully standardized to ensure compatibility across the entire system.

2. Mesh Basket Structural Optimization

• Balance Between Strength and Air Permeability:Maximize the opening ratio while ensuring load-bearing strength.
• Workpiece Fall Prevention: Design mesh sizes based on the dimensions of the smallest workpieces, or install fine-mesh liners.
• Easy Emptying: Incorporate openable side doors or bottom doors for convenient discharge of processed workpieces.

3. Material Selection

• Tray Base: RA330 alloy, ensuring structural strength and creep resistance at high temperatures.
• Mesh Basket: AISI 314, 310S, or RA330 wire/plate. Select materials based on temperature, atmosphere, and load requirements; the chosen material must exhibit excellent oxidation and deformation resistance.

III. Typical Application Scenarios
This type of fixture is particularly suitable for high-volume, small-to-medium-sized, regularly shaped or bulk-loadable components, such as:

• Automotive Industry: Fasteners (bolts, nuts), gaskets, pinions, valve seats.
• Bearing Industry: Rollers, cages, small-to-medium-sized bearing rings.
• General Machinery Industry: Standard parts, pivot pins, chain plates.
• Process Types: Full-process applications including carburizing, carbonitriding, quenching, tempering, and cleaning.

IV. Summary

The tray-mesh basket fixture is the essential extension of the tray furnace technical concept. It separates "logistics from process" — the base is responsible for precise logistics, while the mesh basket undertakes process-related loading. This design achieves the following:

• Ultimate compression of production cycle time
• Ultimate flexibility in product changeover
• Stable guarantee of heat treatment quality
• Significant reduction in the total cost of ownership (TCO) of fixtures

It is not merely a fixture, but the core carrier of a "flexible production material handling system built around tray furnaces". Adopting this fixture means that enterprises opt to operate their heat treatment production lines with a systematic and modular mindset, which is a crucial step towards efficient smart manufacturing.
