Ultra-high precision core pins using advanced technology.
Our ferrules for optical communication connectors and capillaries for semiconductor bonding are produced using ceramic injection molding. To enhance dimensional accuracy, we have developed and manufactured high-precision core pins in-house for use in the injection molding process. With this technology, we manufacture and supply core pins and stepped pins tailored to our customers' needs. We use several types of diamond wheels with different grits on ultra-fine particle cemented carbide and finish them with high precision using in-feed plunge machining.
