Custom Ceramic Injection Molded Parts with High Precision

End-to-End Net-Shape Ceramic Manufacturing

Ceramic Injection Molding (CIM) integrates the geometric versatility of thermoplastic injection molding with the extreme hardness, chemical inertness, and thermal stability of technical ceramics. It allows engineers to specify complex 3D structures with thin walls, internal channels, and micro-features that traditional CNC diamond machining cannot perform economically.

  • Micron Tolerances: Achieves ±0.001mm (1µm) after precision secondary grinding.
  • Mirror Polish: Surface roughness down to Ra 0.01µm directly or post-polished.
  • Zero MOQ Constraints: Seamless scaling from single-unit prototypes to high-volume manufacturing.

Ceramic Injection Molding FAQs

Direct engineering answers to common procurement and design questions.

1. What is Ceramic Injection Molding (CIM) and when should I select it over CNC machining?
CIM combines sub-micron ceramic powders with organic binder systems to form feedstock, which is molded under high pressure into complex geometry parts before debinding and high-temperature sintering. You should choose CIM over CNC machining when part quantities exceed 500 units and the design includes complex 3D shapes, thin walls (<1mm), or internal channels that would require prohibitive diamond-tooling costs on traditional CNC machines.
2. What dimensional tolerances and surface finishes can XY Global guarantee?
Directly from sintering, CIM components maintain standard tolerances of ±0.3% to ±0.5% of nominal dimensions. By implementing secondary CNC diamond grinding and lapping, we routinely guarantee dimensional tolerances as tight as ±0.001mm (1µm) and surface roughness values down to Ra 0.01µm mirror polish.
3. Which ceramic material is best suited for my application?
Selection depends on operational parameters:
Alumina (Al₂O₃) is ideal for electrical insulation and cost-effective wear resistance.
Zirconia (ZrO₂) offers maximum mechanical strength, impact toughness, and medical biocompatibility.
Silicon Nitride (Si₃N₄) excels in high-stress, dynamic mechanical environments with severe thermal shock.
Aluminum Nitride (AlN) & SiC are optimized for high-power thermal management and semiconductor wafer processing.
4. What are your typical lead times for prototypes and mass production?
We provide rapid prototyping without mold tooling in as fast as 3 business days using soft-tooling or direct ceramic machining techniques. Production mold fabrication requires 7 to 14 days, followed by immediate sample validation and seamless ramp-up to mass production.
5. How does XY Global ensure quality consistency across large order volumes?
Our facility operates under strict ISO 9001:2016 and ISO 13485:2015 Quality Management Systems. We utilize 3D Coordinate Measuring Machines (CMM), optical projectors, laser surface profilers, and density testers. Every batch undergoes 100% critical feature inspection before shipment.
