We will give full play to our own advantages, continue to improve and provide quality products, excellent services to serve users and the society. We have always been committed to continuous innovation in technology and management, embarked on a virtuous circle of large-scale operations, and have a professional technology research and development team.

In the production process of quartz crucibles, it is most common to use the arc generated by the graphite electrode discharge to heat and melt the quartz crucible. Traditionally, three graphite electrodes are generally used as a group. Since the quartz crucible is an important accessory for solar and semiconductor single crystal silicon production, its purity requirements are relatively high, so the graphite electrode for quartz crucible must also be of high purity. We can supply graphite electrode and mold with purity less than 50ppm.

Materials suitable for graphite mold

Product Description

For the quartz crucible used in the crystal drawing of monocrystalline silicon, graphite is used as a mold and graphite electrode in the manufacturing process. It makes full use of the characteristics of graphite, such as high temperature resistance, non wetting, conductivity and so on.

Product Features

Conventionally, we use high-purity graphite materials to produce graphite electrode for quartz crucible. High quality graphite electrode is very helpful to improve the product qualification rate of quartz crucible and reduce the quality defects on the inner surface of quartz crucible.

Our company uses extruded graphite rod with high strength and low ash content to process graphite electrode for quartz crucible. This graphite electrode has high purity and excellent conductivity, and has been widely recognized by customers at home and abroad.

Graphite machining process

SHJ has a variety of mechanical processing production lines, customized processing according to drawings, while meeting customers' different precision requirements, select the most cost-effective processing technology with the shortest processing time.

Packaging and shipping

Customized packaging according to customer needs and product characteristics, we can provide customers with laser marking, clean and sealed packaging of purified products, cartons, wooden boxes and other different packaging options.

According to the cargo weight and delivery requirements, choose the most cost-effective transportation method, express, sea, airway, railway, multimodal transportation are available.

Our eternal pursuits are the attitude of 'regard the market, regard the custom, regard the science' as well as the theory of 'quality the basic, have confidence in the very first and management the advanced' for Molded Pressed Graphite. We will continue to consolidate our capabilities, realize professional operation and management with a more open and tolerant attitude, and wholeheartedly provide customers at home and abroad with excellent products and services. Customers' satisfaction is our best advertising.
