Alumina Rectangular Trays
My factory looking for distributors.

Advantages of alumina rectangular trays
Alumina trays can maintain stable physical and chemical properties in high temperature environments (up to 1800 ℃), and their high temperature stability is due to the high melting point characteristics of alumina ceramics. Alumina ceramics have strong resistance to corrosive media such as acid, alkali, and salt. Alumina materials are non-toxic and do not breed bacteria, meeting the hygiene standards of the food and medical industries.
Applications of alumina rectangular trays
1.Alumina trays used in furnaces and kilns for heat treatment processes in industries such as metallurgy, ceramics, and glass manufacturing.
2.Alumina trays used in employed in handling corrosive chemicals, acids, and alkalis in chemical laboratories and industrial plants.
3.Alumina trays used as substrates for electronic components due to their electrical insulation properties and thermal stability.
4.Alumina trays utilized in laboratory settings for handling and processing of chemicals, samples, and medical devices.

How to clean up
1. Wear caring gloves and refuge glasses.
2. Use a soft cloth to remove any dust and dirt from the alumina tray.
3. Fill the alumina tray with warm up water and a mild detergent.
4. Scrub up the alumina tray with a soft brush to remove whatever residue.
5. Wash the alumina tray with clean water and allow them to dry out completely earlier use.
Our factory
Established in May 2000, Jinzhou Yunxing Industrial Ceramics Co., Ltd. originated as Jinzhou Yunxing Technology Development Co., Ltd. Initially located within the enterprise incubator factory on Yulu Street, High-Tech District, our company relocated in April 2002 to a leased industrial site owned by the Agricultural, Industrial, and Commercial Corporation in Taihe District. By the end of 2006, to accommodate expansion, we moved to No. 9 Weimin Road, Fantun Village, Yingpan Town, Taihe District, and subsequently adopted our current name. In December 2023, we transitioned to our new premises at No. 5 Xinggong Road,Taihe District ( Da Xu Industrial Park, Yingpan Town, ).
The company's main products are: alumina ceramic tubes, alumina ceramic crucibles, alumina ceramic rods, alumina ceramic boats, alumina ceramic plates, alumina ceramic parts, etc.
Our workforce comprises over 70 dedicated employees, including 1 senior engineer and 5 engineers and technicians. We specialize in the production of industrial ceramics with a 99.3% alumina content, catering primarily to industries such as instrumentation temperature measurement, industrial furnaces, university laboratories and testing of inorganic non-metallic materials. In 2023, we achieved a sales revenue of 15.78 million yuan and contributed 1.88 million yuan in taxes, amounting to a cumulative tax contribution of 20.13 million yuan over the years.
Our products are widely used in Semiconductor, Medical, Aerospace, Scientific Research, Fluid Controlling, Food Processing, Automotive, Defense, Thermal Processing, Electronic and Electrical, Mineral Processing,Textile, Pulp and Paper, Glass Processing, Mechanical Engineering, etc.
