Environmental Report 2013
Reducing Usage of MaterialsIn an effort to use materials more efficiently, measures that reduce the amount (percentage) that becomes waste after being introduced into the manufacturing stage are being promoted. An introduction to efforts at each site to use the main materials more effectively is provided below.
●Efforts at JAE and YAE sites
Measures are underway for reducing the amount of materials used and waste generated by downsizing molds and revising the width of metal materials used in presses. In addition, material input is being reduced by reusing recycled molding materials, and this has resulted in a major reduction of CO2 emissions.
●Efforts at HAE site
HAE is focusing on reduction of the amount of materials used by reducing the width of metal materials used in presses and pin protection materials. The reduction of molding materials is being achieved by reducing unnecessary spoolers/runners that are discharged when extracting molded products; improving the number gates, mold shape, and positioning when designing molds; and switching from cold runners to hot runners. This reduces the amount of molding material used, while using recycled materials reduces the amount of newly purchased material inputs.
●Efforts at FAE site
Efforts to improve the reuse rate for copper alloy electrode material used in the manufacturing process for metal parts (discharge machining) are contributing to a dramatic reduction in the quantity of material used and the metal waste generated. Material usage was reduced by 261.0kg, exceeding the target of 200 kg.
●Efforts at SAE site
Efforts continue to reduce the size of machining (cutting) material for large machined components. Although the amount of base materials used has increased in conjunction with a rise in the amount of components produced, optimizing machining methods for each one and keeping base material size as small as possible has reduced the amount of waste metal and dramatically contributed to curbing CO2 emissions during material production.
