At Big Ceramics, we utilize a variety of advanced ceramic molding capabilities to create cost-effective advanced ceramic products for our customers. We will consult with our customers to determine the best solution to meet their needs based on factors such as product raw materials, size and accuracy, and order quantities.

Advanced ceramic molding methods can be divided into dry molding and wet molding. Dry molding including dry pressure, isostatic pressure, ultra-high pressure molding, powder electromagnetic molding. Wet molding can be broadly divided into two categories: plastic molding and colloidal casting. Plastic molding refers to the plastic material pressed into a hard mold molding methods, including extrusion molding, injection molding and so on.

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

Ceramic injection molding (CIM) has the advantage of mass production of ceramic products with high dimensional accuracy and complex shapes. It has been widely used in aerospace, automotive, machinery, energy, optical communications, life medicine and other fields. It has significant advantages over traditional molding methods:

• Cost-effective technology; and;
• Suitable for mass production.;
• Realization of very high dimensional requirements (≤ 1% dimensions).;
• Reduced manufacturing costs.

Currently, materials suitable for ceramic injection molding are:aluminum oxide,zirconium oxide,aluminum nitrideetc.

Big Ceramics offers ceramic tubes or rods made from extrusion molds in custom sizes and complex shapes. Typically, such products consist of alumina ceramics or mullite, which provide functions such as high-temperature protection or electrical insulation. The process is widely used for the preparation of ceramic furnace tubes, electromagnetic insulators, catalyst carriers, heat exchanger tubes, honeycomb ceramic carriers for exhaust filtration, and so on.

Ceramic hot die casting can form a complex shape of ceramic products, high dimensional accuracy, almost no need for subsequent processing, so it is the main process of making shaped ceramic products. In addition, due to the low price of production equipment, easy to make, high production efficiency, production cost is relatively low.

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 ceramic products.

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

• Pressure is transmitted from all directions, the density of raw briquettes is uniformly distributed, and the strength of raw briquettes is high.;
• High billet density, uneven defects, lower firing shrinkage than normal dry pressing;
• Complex shapes such as concave and elongated parts can be pressed.;
• Low friction loss and low molding pressure.;
• Low mold cost.

• Preparation of high-performance alumina ceramic raw materials, such as ceramic tubes, ceramic rods, ceramic plates, etc.;
• Preparation of high-performance alumina ceramic part blanks in various shapes.;
• Alumina ceramic vacuum switch interrupter “shell” series products, alumina and zirconia ceramic plungers, 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 compression molding is a good fluidity, particle gradation of the appropriate granular powder into the metal mold cavity, through the indenter to apply pressure. The block particles are rearranged and deformed and compacted to form a ceramic blank with a certain strength and shape.

• Simple process, convenient operation, short cycle time, high efficiency, easy to realize automatic production.;
• Raw blanks have high density, accurate dimensions, low shrinkage, high mechanical strength and good electrical properties.

It is especially suitable for the preparation of various ceramic products with small cross-section thickness, such as ceramic seals, ceramic spools for valves, ceramic linings, ceramic liners and so on.
