Quality & Technology Initiatives

We hold and continuously maintain ISO9001-2008 quality management system certificate and ISO14001-2004 environmental management certificate from International Organization for Standardization


As a step to improve our technical capability, each production worker has to conduct his or her own investigation, conduct experiments and generate a corrective action report whenever a technical issue, no matter big or small, occurs.

Labor saving (cutting process) by mechanization

Before the improvement After the improvement
Content detail Putting the unprocessed items in and taking the processed items out were carried out by workers manually. Automatic loader system is adopted, automating process work input work of products.
Problems and Improvements The labor is ineffective.
There’s a safety problem for the workers.		 It’s been made possible for one person to operate two outer diameter detectors. The safety improves the discarding of manual labor.
Effect.
Effects It needs one worker per piece of equipment. Two pieces of equipment can be handled by one person, the labor effectiveness is twice (half the amount of labor)

Labor saving (Press fit) by mechanization

Before the improvement After the improvement
Content detail It used to take more of a workload before because of the manual labor as they had to reset pipes and pins each item in operation. The assembly line system became possible and the number of seconds for pressing shortened.
Problems and Improvements It used to take more of a workload before because of the manual labor as they had to reset pipes and pins each item in operation. The assembly line system became possible and the number of seconds for pressing shortened.
Effects One worker needs to be working per press fitting machine. No worker has to stay and work at the press fitting machine anymore.A reduction in labor and a shortened number of seconds per process.

Labor saving (parker process) by mechanization

Before the improvement After the improvement
Content detail Processing length of time each tank, moving between tank to tank was done manually by workers. The immersion time is controlled by an alarm system. Moving to each tank was made automated by using a hoist.
Problems and Improvements There are some failure occurrences because of silly mistakes such as the inappropriate processing time (exceeded). By setting controlling the processing time, operational efficiency became possible through automation moving with hoist.
Effects Effective quality is varied Stable quality where the defective level doesn’t come down and the reduction of the defective level.

Improvement of surface roughness accuracy (Ry3.0→Ry1.0)

Before the improvement After the improvement
Content detail The remittance of the process by the existing equipment. Installation of processing equipment specialized for surface roughness.
Problems and Improvements It is difficult to process high accuracy surface roughness. Improvement of surface roughness accuracy.
Effects Regular aluminum product’s surface roughness.
Non-specular Ra1.6 or less.
Mirror surface Ra0.4 / Ry1.6		 Ra0.2 / Ry1.0 or less can be processed.

Reduction of center less polishing times.

Before the improvement After the improvement
Content detail Roughness polishing process that used to be conducted with the conventional number of polishing times. The number of polishing times reduced by reviewing the polishing amount and conditions of ｒoughness polishing process.
Problems and Improvements The number of polishing times are a lot = more cost.When the polishing amount per time increased, the processing load to the products will be more. Each level of polishing amount and speed were tested and achieved a reduction in the number of polishing times.
Effects Without reducing the number of roughness polishing times, the cost of processing will not be reduced. Also, when the number of products increase, the processing facility will not be enough. The reduction of processing cost and an increase in processing equipment capacity were realized by shortening the time for roughness polishing.
