At Great Ceramic, we utilize a variety of advanced ceramic forming capabilities to create cost-effective advanced ceramic products for our customers. We will negotiate with customers based on factors such as product raw materials, size and precision, and order quantity to determine the best solution that meets customer needs.

Advanced ceramic forming methods can be divided into dry forming and wet forming. Dry forming includes dry pressing, isostatic pressing, ultra-high pressure forming, powder electromagnetic forming, etc. Wet forming can be roughly divided into two categories: plastic forming and colloidal casting. Plastic molding refers to a molding method in which plastic materials are pressed into rigid molds, including extrusion molding, injection molding, etc.

Our services include: dry pressing, hot pressing, cold isostatic pressing, extrusion, injection moulding (CIM), etc.

Great Ceramic offers ceramic tubes or rods made from extrusion dies, and can be customized to size and complex shapes according to customer needs. Typically, such products are composed of alumina ceramics or mullite for functions such as high temperature protection or electrical insulation. This process is widely used in the preparation of ceramic furnace tubes, electromagnetic insulators, catalyst carriers, heat exchange tubes, honeycomb ceramic carriers for exhaust filtration, and the like.

Ceramic hot die casting can form complex-shaped ceramic products, with high dimensional accuracy and almost no subsequent processing, so it is the main process for making special-shaped ceramic products. In addition, the production cost is relatively low because the production equipment is inexpensive, easy to operate, and high in production efficiency.

However, due to the low molding pressure of ceramic hot die casting, it is easy to lead to low product density, high porosity, and many internal defects. This process is not suitable for the preparation of large-scale ceramic products.

The so-called isostatic pressing generally refers to cold isostatic pressing (CIP), which is a method of obtaining ceramic products by using the incompressibility of the liquid medium to uniformly transmit pressure and pressurizing from all directions. . According to the different molding process, it can be divided into two forms: wet bag type and dry bag type.

• The pressure is transmitted from all directions, the density distribution of the green compact is uniform, and the green compact strength is high;
• The green body has high density, less uniform defects, and the firing shrinkage is lower than the general dry pressing;
• It can press parts with concave, slender and other complex shapes;
• Small friction loss and low molding pressure;
• The mold cost is low.

• Preparation of high-performance alumina ceramic raw materials, such as ceramic tubes, ceramic rods, ceramic plates, etc.;
• Preparation of high-performance alumina ceramic parts blanks of various shapes;
• Alumina ceramic vacuum switch arc interrupter “tube shell” series products, alumina and zirconia ceramic plungers, and large-size zirconia ceramic cylinder liners for oil drilling, etc.

Dry pressing, also known as molding, is one of the most commonly used molding methods. Dry press molding is to put the granulated powder with good fluidity and suitable particle gradation into the metal mold cavity, and apply pressure through the indenter. The bulk particles are rearranged and deformed and compacted to form a ceramic green body with certain strength and shape.

• The process is simple, the operation is convenient, the cycle is short, the efficiency is high, and it is easy to implement automatic production;
• The green body has high density, accurate size, small shrinkage, high mechanical strength and good electrical properties.

It is especially suitable for the preparation of various ceramic products with small cross-sectional thickness, such as ceramic sealing rings, ceramic valve cores for valves, ceramic linings, ceramic linings, etc.
