Ceramic Manufacturing - Injection Molding

Ceramic Injection Molding (CIM) is a manufacturing process that utilizes injection molding technology to produce complex engineering ceramic parts.

GORGEOUS CERAMICS (GGS) has been deeply involved in the CIM manufacturing field for many years, focusing on the research and development and production of complex structures and high-precision ceramic parts, and is committed to providing customers with stable and reliable mass production solutions.

Injection molding first involves uniformly mixing ceramic powder with an organic binder to prepare a material suitable for injection molding. After molding in an injection molding machine, the material undergoes debinding and high-temperature sintering to achieve mass production of high-density, highly consistent ceramic parts.

Compared to traditional ceramic processes, CIM (Ceramic Injection Molding) can efficiently achieve the integrated molding of complex structures and ceramic parts that are difficult to produce using traditional methods. Therefore, CIM is one of the most important solutions among many molding processes.

Model Flow Analysis

In CIM (Chemical Injection Molding) processes, flow and filling analysis is crucial for ensuring product quality. GORGEOUS CERAMICS (GGS) utilizes precise numerical simulation technology to accurately predict material flow behavior in the mold before actual production, effectively identifying potential defects in ceramic products, including microcracks, trapped air, and bubbles.

Furthermore, based on the analysis results, we optimize the design of key structural areas of the product, such as gate location and runner design, mitigating molding defects from the design stage.

Ceramic Injection Molding Process Flow

Key steps explained:

Granulation- The ceramic powder and organic binder are precisely mixed and granulated in a controlled ratio to prepare granular raw materials suitable for injection molding.
Injection- The raw materials are heated and melted using an injection molding machine, and then injected into a mold to form a ceramic green body of the desired shape. We support thin-walled, microporous, and other fine ceramic structures, as well as one-piece molding.
Debinding- Precisely control the temperature and rate to remove organic binders from the ceramic body, transforming it into brown part with a certain strength.
Sintering- The green body undergoes high-temperature densification treatment, which is then sintered under high-temperature conditions. The temperature curve is precisely controlled to ensure the performance of the ceramic product.
Inspection- Sintered products undergo rigorous quality system testing (including dimensions, appearance, performance, etc.). Data is traceable, and quality is guaranteed.
