Multi-Lab - Bespoke Ceramic Components
FromMulti Lab
Due to the ever increasing demand for Precision engineered ceramic components Multi-Ceramic Technology was formed in August 2009. The focus of this company was to aid our customers both current and new to design and attain various ceramic parts in various forms and materials for their ever increasing applications.

DESIGN GUIDELINES
PLATING SPECIFICATIONS
- Section Thickness
- Cross sections with uniform wall thickness are desirable.
- Process Characteristics
- Draft angles, parting lines, flow lines, and ceramic flashes can be minimized by Multi Lab engineers who will work with you on your design.
- Recommended Radii
- Sharp corners can be designed to a minimum of 0.010" radius where required. Internal cavity radii should be designed with a more generous fillet. Contact Multi Labs technical staff for assistance with specific design considerations.
- Undercuts
- External tapers and undercuts are possible, however as a general rule, undercuts should be avoided.
- Tolerances
- Without secondary operations, Multi Labs process is capable of tolerances of ± .5% to ± 1% NLT ± .0762 mm (.003") Surface flatness is typically .0762 mm (.003"/ inch) or better. The smallest part is typically 1.2 grams (.042 oz)and the largest part is typically 150 grams (5.29 oz). Larger and smaller custom parts are possible. Review your requirements with Multi Labs technical staff.
- Finishing Operations
- After sintering, the parts are inspected to high quality standards. Additional operations may be performed such as plating, brazing or machining as required.

INJECTION MOLDING PROCESS
- Applications
- Multi Labs technical team will help guide your design to meet the tooling requirements for maximized manufacturability.
- Materials Preparation
- High purity ceramic is mixed with a proprietary blend of organic materials called "binders," and processed into a fluid base with rheological properties for mold filling.
- Molding
- The material is injected into a mold with single or multiple cavities under pressure. The green part is then rapidly ejected from the mold.
- De-binding
- The binders are removed through thermal processing.
- Sintering
- The ceramic parts are fired at high temperatures in excess of 1600°C that allows the part to reach density.
- Finishing Operations
- After sintering, the parts are inspected to high quality standards. Additional operations may be performed such as plating, brazing or machining as required.
