Mastering Complexity: Ceramic Injection Molding (CIM) for Micron-Precision Advanced Ceramic Parts | CRAC Solution

Introduction: When Standard Manufacturing Fails Precision

In sectors demanding high wear resistance, thermal stability, and biocompatibility—from smart wearables to medical devices—components are shrinking while complexity increases. Traditional ceramic manufacturing methods often struggle with low yields, high tooling costs, and limited geometric capabilities when attempting to mass-produce small parts featuring threads, internal features, or extremely fine tolerances.
Chuangrui Advanced Ceramics (CRAC)​ leverages the Ceramic Injection Molding (CIM)​ process to deliver solutions where conventional methods fall short. CIM, recognized as the fastest-developing and most widely applied near-net-shape ceramic plastic forming technology, is an essential interdisciplinary application, integrating plastic injection molding and ceramic sintering. CRAC utilizes CIM to facilitate the mass production of small-sized, precise, and complex advanced ceramic products.

CIM: The Technological Bridge to Unconstrained Design

Ceramic Injection Molding liberates product design from the constraints of conventional processes. By blending ceramic powders with polymer binders and injecting the mixture into molds, CIM allows for the creation of intricate parts in a manner similar to plastic molding.

Why CIM is the Apex of Ceramic Forming:

  1. High Degree of Design Flexibility:​ CIM allows for the design of special-shaped structures​ both internally and externally. This includes the efficient creation of features such as internal threads, undercuts, and small apertures.
  2. Micron-Level Precision:​ CRAC specializes in molding ceramics for small, complex, and precise parts. While a general tolerance accuracy of ±0.5%​ can be obtained, even higher dimensional accuracy​ can be achieved when combined with other post-processing methods.
  3. Robust Material Performance:​ CIM utilizes high-performance advanced ceramics—inorganic nonmetallic materials distinguished by their capacity to integrate mechanical, thermal, and optical properties in an extremely complex manner. These parts boast superior characteristics, including high density, high strength, high fracture toughness, and high hardness.

Performance Data: The Material Foundation for CIM Success

CRAC processes a variety of high-performance materials through CIM, strictly following design specifications. The selection of the material dictates the final mechanical strength and wear resistance of the injected part.
