Words from our CEO

Words from our CEO

Taking a new leap with new challenges Taking a new leap with new challenges

I would like to take this opportunity to show my gratitude to our customers’ continuous feedback and support.
We started our operation as a casting specialist manufacturer in 1966. With our main expertise in construction machinery, our business has developed by responding to the needs of various industries, such as small lot productions of many products in varied sizes.
We strive to always use all we have and take technology, ability and quality to even higher levels. All our staff are determined to ‘take a new leap with new challenges’, aiming to become a manufacturer who can actively offer our ideas for product development rather than settling for a conventional supply style of manufacturing to order.
