600G/M2 Woven Fiberglass Silicone-Graphite PTFE Finish Filter Bag
We produce and supply processed graphite products for application of semiconductor industry.
Description
We are committed to the development of domestic products, provide high-quality Graphite Crucible for Aluminum, artificial graphite block, Graphite for float glass for domestic and international markets, and have formed large-scale production. We hope to lead and promote the industry from scratch, from small to large, from weak to strong development process. We believe that all staffs earnestly study and establish a good corporate culture is the basis of enterprise development.
We produce and supply processed graphite products for application of semiconductor industry. We have several CNC machining centers with high revolutions to ensure mechanical tolerance, and we have three coordinate measuring instruments, which can check the tolerance of processed work pieces to ensure the measurable quality. At the same, we have the state of the art purification furnaces, which can purify the processed products to ash content less than 2PPM.

Product Description
Components used in semiconductor environment have high requirements for particle size. It not only needs to apply the good physical properties of graphite, such as high temperature resistance, corrosion resistance and plasma resistance, but also has high requirements for the purity and machining accuracy of graphite.
We use imported purification equipment of international well-known brands, which can extract the purity of graphite processed parts to 5-50PPM, and the ash content of specially ordered products can be less than 2PPM.
The main applications include graphite thermal field in semi-con single crystal furnace, including heating element, crucible, insulation cylinder, packaging fixture, etc.
