Quality-Related Initiatives

Our commitment to product quality

One of Yamabiko Corporation's strengths is an integrated production system that covers everything from raw materials to casting, metal working and machining to assembly for the two-cycle engines mounted on our chainsaws, trimmers and brushcutters.
We produce over 2.0 million two-cycle engines every year, and we have unique production technology for the mass production of compact, high-performance engines.

One of them is “iron plating,” a kind of plating technology. Compared to chrome plating, it has the advantage of being kinder on people’s bodies and the environment as well as costing less. We use this technology to plate engine cylinders. Although we faced the challenge of hardness and the precision of plating thickness, after much repeated research starting with the materials themselves, we resolved these issues and arrived at one of our most excellent technologies.

Electrical discharge machining (EDM) is another important technology that sustains our high quality. EDM is generally thought to be unsuitable for mass production because of its long processing times. However other methods did not work well when machining engine cylinders with complex shapes, so we honed the quality using our unique machining process and succeeded in mass production. We use our proprietary technology for parts which cannot be shaped through casting. These production technologies coupled with our product development technology allow us to produce high-quality engines that also comply with the strict gas emission regulations of various countries.

We have these other initiatives as well.
