Latest Patents

Among Sugaya's most notable recent inventions is a brake drum and method for producing the same. This innovative brake drum is designed with a ring-shaped drum body made from a lightweight aluminum alloy, coupled with a friction member secured to the inner circumferential surface of the drum body. By utilizing an aluminum-base composite material for the friction member, this design significantly reduces the overall weight of the brake drum. Importantly, the friction member features projection portions on its outer periphery that are cast enveloped by molten aluminum, ensuring a strong bond with the drum body. This design effectively prevents undesirable detachment even under high braking forces.

Another significant patent is for a method and apparatus for casting aluminum using a casting mold. In this process, the cavity is first filled with an inert gas, followed by the introduction of magnesium to create a magnesium layer on the cavity wall. Subsequently, nitrogen gas is introduced to form magnesium nitride on the surface of the magnesium layer once the cavity wall reaches a specific temperature. This method allows for the efficient formation of magnesium nitride in a short time frame while reducing the necessary quantity of nitrogen gas, enhancing the overall efficiency of aluminum casting.
