Manufacturing & Technical Capabilities
From raw powder blending to high-precision finishing, CTI maintains end-to-end control over the manufacturing process to ensure consistent metallurgical integrity.
Core Manufacturing: Press & Sinter
Our facility is equipped for the complete production of powdered metal contacts.
• In-House Blending: Custom mixing of silver, copper, and refractory powders to meet precise customer specifications.
• Pressing & Sintering: Utilizing advanced powder metallurgy to create high-density components with superior mechanical and electrical properties.
CNC Machining
Highly capable multi-axis machines that turn raw sintered products into finished parts.
Surface Preparation & Finishing
We provide specialized surface treatments to ensure our contacts are ready for seamless integration into your assemblies.
- Silver Enrichment: For graphite-based contacts, we strategically remove surface graphite to leave a high-conductivity silver layer, ensuring a superior bond during soldering.
- Chemical Etching: Creates a high-conductivity surface optimized for soldering and brazing requirements.
- Solder Application: We offer flexible delivery—contacts can be shipped pre-soldered or prepared for your own in-house soldering process.
- Tumbling: Deburring and surface conditioning to ensure part uniformity and eliminate mechanical interference.
Advanced Brazing Solutions
CTI offers multiple brazing methods to match the thermal and mechanical requirements of your sub-assemblies.
- Resistance Brazing: Provides localized heat, which is essential for maintaining the hardness and temper of the surrounding components.
- Induction Brazing: High-precision, localized heating for consistent, high-volume production.
- Furnace Brazing: Ideal for fully annealed parts requiring a uniform thermal profile.
- Specialty Methods: Ultrasonic and Friction brazing available upon request.
