Can this holding tray be used in autoclave sterilization?

Yes, the 304 stainless steel construction is suitable for autoclave sterilization at temperatures up to 134°C (273°F) and pressures up to 2.1 bar. The material resists corrosion from steam and common sterilization chemicals. However, ensure the tray is properly cleaned before sterilization to remove any residues that could affect the process. After autoclaving, allow the tray to cool gradually to prevent thermal stress. Regular inspection for signs of pitting or discoloration is recommended, though the polished surface minimizes such risks.

What is the maximum load capacity and how was it determined?

The maximum load capacity is 15kg, determined through static load testing with a safety factor of 2.0. The tray's 1.2mm thick stainless steel sheet and reinforced corners distribute weight evenly, preventing deformation under the rated load. For dynamic applications (e.g., moving the tray), reduce the load to 10kg to account for acceleration forces. Exceeding the capacity may cause permanent bending, which could affect dimensional accuracy and fit in automated systems.

How does the 50mm depth compare to other trays in the series?

The 50mm depth is 20mm deeper than the standard 30mm trays in the same series, providing 67% more containment volume. This makes it better suited for holding small parts like screws, electronic components, or surgical instruments that could otherwise spill over shallow edges. The increased depth does not compromise stackability; the trays can still be nested with a 10mm gap for ventilation. For applications requiring even higher containment, a 70mm deep model is available.

Is the tray compatible with chemical cleaning agents?

The 304 stainless steel offers good resistance to most common cleaning agents, including mild acids, alkalis, and detergents. However, avoid prolonged exposure to chlorides (e.g., bleach) as they can cause pitting corrosion. For disinfection, use quaternary ammonium compounds or 70% isopropyl alcohol. After cleaning with any agent, rinse thoroughly with water and dry to prevent residue buildup. The polished surface facilitates easy cleaning and reduces the risk of chemical attack.

How Does the 400x300x50mm Holding Tray Improve Workflow Efficiency?

The Holding Tray is constructed from 304 stainless steel, a material chosen for its excellent corrosion resistance and mechanical strength. Measuring 400mm in length, 300mm in width, and 50mm in depth, this tray offers a generous surface area of 0.12 square meters while maintaining a compact footprint suitable for benchtop use. The 15kg load capacity allows it to hold multiple electronic assemblies, medical instruments, or heavy tools without deformation. The surface is polished to a roughness of Ra ≤ 0.8μm, which not only enhances cleanability but also reduces the risk of particle adhesion—critical in cleanroom and sterile environments. Each tray undergoes rigorous quality control, including edge deburring and dimensional verification, ensuring consistent performance across batches.

This holding tray excels in applications where organization and hygiene are paramount. In electronics manufacturing, it serves as a reliable carrier for printed circuit boards during assembly and inspection, with the 50mm depth containing small components like screws and connectors. In medical facilities, the 304 stainless steel construction withstands repeated autoclave cycles at 134°C, making it ideal for sterilizing surgical instruments. Workshops and maintenance departments use the tray to sort fasteners and tools, leveraging the polished surface to easily spot small parts. The 15kg capacity supports heavy diagnostic equipment or dense metal components, reducing the need for multiple trips and minimizing downtime.

Compared to smaller or lighter-duty trays in the same series, this 400x300x50mm model offers a balanced combination of size and strength. Its 50mm depth is deeper than standard 30mm trays, providing better containment for loose items, while the 15kg load rating exceeds that of entry-level models by 50%. The 304 stainless steel grade offers superior corrosion resistance to 201 stainless steel, especially in humid or chemical-exposed environments. For applications requiring frequent sterilization or exposure to cleaning agents, this tray eliminates the risk of rust and degradation seen with coated steel or plastic alternatives. The deburred edges and smooth finish also reduce the chance of snagging gloves or scratching delicate components, enhancing both safety and product longevity.

Core Technical Features and Quantified Advantages

STEP 1

304 Stainless Steel Construction

The tray is made from 304 stainless steel, containing 18% chromium and 8% nickel, which provides excellent resistance to oxidation and corrosion. This material is suitable for repeated exposure to moisture, chemicals, and temperatures up to 800°C, ensuring long-term durability in harsh environments. The polished surface (Ra ≤ 0.8μm) further enhances corrosion resistance by minimizing surface defects where contaminants could accumulate.

STEP 2

15kg Load Capacity with 50mm Depth

With a load capacity of 15kg, the tray can support heavy components such as metal fixtures, dense electronic assemblies, or multiple medical instruments without bending. The 50mm depth is specifically designed to contain small parts like screws, nuts, and connectors, preventing them from rolling off during transport or assembly. This combination of strength and containment reduces the risk of lost components and improves workflow efficiency.

STEP 3

Polished Surface (Ra ≤ 0.8μm) for Cleanability

The surface roughness of Ra ≤ 0.8μm is achieved through mechanical polishing, which removes microscopic peaks and valleys that can harbor bacteria or particles. This finish meets cleanroom standards for particle shedding and allows for easy wiping with disinfectants. In medical and electronics applications, this level of smoothness reduces the risk of contamination and simplifies cleaning procedures, extending the tray's service life.

STEP 4

Deburred Edges and Dimensional Accuracy

All edges are deburred and rounded to eliminate sharp corners that could cause injury or snag gloves. The tray's dimensions are controlled within ±1mm tolerance, ensuring compatibility with standard shelving and automation equipment. This precision manufacturing guarantees that the tray fits consistently into existing workflows, reducing setup time and improving operational safety.
