MIM: High-Density Alumina Ceramic Trays for Powder Metallurgy Sintering

1. Advantages of High-Density Alumina Sintering Trays:

Our multi-porous high alumina sintering trays, designed for optimal heat storage and exceptional high-temperature resistance, ensure a seamless sintering process and precise dimensional accuracy of components. With features like thermal shock resistance and chemical reaction resistance, these trays are a testament to our dedication to quality and innovation.

• Enhanced Porosity: Facilitates smooth degassing and degreasing of parts.
• Optimal Heat Storage: Ensures even heat distribution, preventing uneven cooling and ensuring consistent thermal expansion and contraction.
• Superior Flatness: Guarantees that parts undergo thermal processes on a consistent plane.

2. Applications of High-Density Alumina Trays:

• Perfect for sintering large components, especially when consistency and density post-sintering are paramount.
• Designed for rapid cooling conditions, such as continuous furnace water cooling, ensuring excellent thermal shock resistance and minimal cracking risks.
• Compatible with advanced furnace atmospheres, thanks to technological advancements that reduce graphite atmosphere evaporation and ensure efficient impurity removal.

3. Challenges with Prolonged Use of High-Density Alumina Trays

• Shedding: Due to their granular nature and required porosity, these trays may shed over time. However, optimal material ratios and sintering temperatures can mitigate this.
• Deformation: Factors like tray thickness, load weight, and loading method can influence deformation. Increasing tray thickness can address warping issues at high temperatures.
• Discolouration: Various factors, including the type of stainless steel being sintered and furnace conditions, can cause discolouration. Regular maintenance can help address this.
• Fuzz: Over time, a white or black fuzz may develop on the tray surface.

4. Optimizing Performance of High-Density Alumina Ceramic Trays:

• Employ the right material ratios and sintering temperatures to minimize shedding.
• Adopt a thicker tray design to reduce high-temperature warping and deformation.
• Ensure regular furnace maintenance to prevent discolouration and maintain an optimal atmosphere.
• Conduct routine tray cleaning to prevent fuzz formation.
• Use dedicated trays for different stainless steel types to avoid cross-contamination.
