Diamond sprue bushings are ideal for injection molding of filler-reinforced plastics. They offer excellent wear resistance and help prevent “progressive wear at the nozzle contact point,” which is a common cause of resin leakage issues. These bushings are crafted from high-quality diamond, a material that—in addition to its high hardness—exhibits low wettability. Furthermore, their service life is more than 10 times longer than that of conventional iron-based metal bushings. This also helps reduce waste.

By using diamond for water jet nozzle, water stream width can be minimized and directness and ultrahigh pressure achieved, resulting in higher precision and longer life. Furthermore, by expanding the width of the water stream, the nozzle can also be used for cleaning and removal of burrs.

The accuracy of the wire guides determines the precision of wire electrical discharge machining(EDM), which is used for metal forming processes in various industries. Asahi Diamond has developed this highly functional diamond wire guide jointly with an electrical discharge machining equipment manufacturer.

・Ribbed Centers: By applying “Sanpax” to the tips of ribbed centers that support workpieces on lathes and grinding machines, we have achieved long-term, high-precision machining.
・Centerless Grinding Blades: By applying “Sanpax” to the wear-prone areas of centerless grinding machine blades, we have achieved high-precision, high-efficiency machining.
・Shoes and rests: The areas of a grinding machine that secure the workpiece require particularly high wear resistance. Using “Sanpax” in these areas makes it possible to maintain high machining accuracy.
・Probes: When measuring the dimensions of machined parts, using diamond or “Sanpax” on the tip of the probe provides high wear resistance and helps maintain measurement accuracy.
