ceramic injection molding
Ceramic injection molding is ideal for high-volume production of complex, tight-tolerance components, ceramic injection molding offers significant advantages over conventional forming methods:
• Cost-effective technique for complex designs
• Ability to produce net or near-net shape parts
• Very tight tolerance control
• Low-cost, high-volume manufacturing runs
Complex ceramic parts can be manufactured easily and reliably
high-quality ceramic injection molding opening up new possibilities for making complex components with economic and technical benefits:
• High degree of automation
• Wide range of shapes
• Near-net-shape manufacturing
• Good mechanical properties
we have a wide range of Ceramics Materials to offer. Each one with its own unique characteristics designed to meet the requirements of many diverse applications. Some of the more widely used materials are described below.

Industrial Ceramic Intriduction
Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
