Optical Core Pins

• Product Accuracy:
• Tolerance of ID and OD to reach 0.002mm
• Concentricity / Roundness / Cylindricity: 0.002mm
• Parallelism / Verticality: 0.002mm

Similar to the core, core-pins are used to create the insides of through or blind holes and are often seperate pins that can be removed for replacement or resizing.

YAO Enterprise Co., Ltd. can provide the opportunity to reduce the cost of producing injection molded parts .

YAO Enterprise Co., Ltd. produces Custom Core Pins from a special high conductivity Tungsten Carbide material.

Tungsten Carbide Core Pins provide thermal conductivity equal to Beryllium Copper (Cu+Be) alloys. The heat in the part can be removed rapidly from injection molded parts with internal cavities.

The rigid Tungsten Carbide Core Pins provide extremely low deflection during the injection process. Internal cavities in the injection molded part, that require long narrow core pins , will experience very low deflection... and tight tolerances can be maintained without sacrificing cycle time.

Tungsten Carbide Core Pin tolerances can be hold to +/-.0001" at Crafts Technology.

Tungsten Carbide core pins also provide a substantial increase in wear life.
