The manufacturing process of graphite crucible can be divided into three types: hand-molding, spin-molding and compression-molding. The quality of graphite crucible has an important relationship with the process forming method. The forming method determines the structure, density, porosity, and mechanical strength of the blank body.

Extruded graphite is produced in an extrusion process. In contrast to isostatic graphite, extruded graphite has a coarser grain size and a lower strength but higher thermal and electrical conductivity. Vibration molded graphite is characterized by a homogeneous structure and typically a medium grain size. The material shows a planar isotropic ...

On average, it takes between 2 seconds and 2 minutes, depending on the size of the mold. In general, there are four major steps that take place in the injection molding process. They include the following. Clamping: The first part of the entire process is securing the mold intended for use through a process called clamping.

Graphite is a naturally occurring modification of carbon (chemical formula: C). Its atoms arrange themselves in the hexagonal pattern, which is typical for carbon, and thus form a hexagonal layered lattice. Graphite gets its typical grey color from its opaque grey to black crystals. While diamond, another carbon modification, is the hardest ...
