What is Graphite boat?
The graphite boat is a kind of graphite mold, using as a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering. The graphite mold is made of artificial graphite blocks by mechanical processing. Graphite boats are also called graphite boxes, graphite saggers, and graphite molds.
Performance characteristics of graphite boat / graphite box
1. Good conductivity (second only to copper and aluminum)
Good thermal conductivity (approximately 1/3 of copper, 1/2 of aluminum, and 2 times of steel at room temperature)
2. The coefficient of thermal expansion is particularly low
The strength increases at high temperatures and approximately doubles at 2500°C. (Compressive strength ≈ 2 times the compressive strength).
Instructions for use of graphite boat / graphite box
Our company produces and processes graphite boxes according to customer drawings, and uses wooden box packaging to ensure the safety of the goods. The timeliness and transportation safety of the cooperative logistics company are guaranteed, so that customers have no worries about after-sales.
Our company produces all kinds of fine-grained high-purity artificial graphite blocks suitable for processing graphite boxes throughout the year, and specializes in processing various specifications of graphite boxes and graphite trays. Using fine-grained high-density graphite as the raw material, the processed graphite box has the characteristics of high temperature resistance, oxidation resistance, high body density, etc., which can be used in a variety of harsh high temperature environments. It is the first product for customers in the high-end graphite industry at home and abroad.
Why choose Jiangxi Ningheda graphite box?
1. Flatten channels and reduce procurement costs. Our company is responsible for the entire link of raw material production-graphite box processing-graphite box sales, which can reduce customer procurement costs.
2. Appropriate graphite raw material size, less waste and low material cost. Our company's fine-grained high-density graphite is currently the most suitable material for graphite cartridge production, with high quality, low price and high cost performance.
3. The processing cycle is short, which can meet the timeliness requirements of customers. Our company is a professional manufacturer of graphite cartridges, with a monthly production capacity of 10,000, which is better than the customer's processing accuracy requirements, and the delivery is timely. It is widely praised by customers at home and abroad.
