About Us

In-Process Inspections

Supertec Machinery Inc. was founded by Mr. Randy Chu in 1997. In order to learn the US culture and observe the manufacturing market thoroughly, Mr. Randy Chu was educated and obtained a university degree in the United States.

Since Mr. Randy Chu’s family operated a precision machinery manufacturing company in Taiwan, he returned to Taiwan after completing his education and helped to expand the family business into the European and American markets. Within several years, Mr. Randy Chu had successfully promoted his products to well-known grinding machine manufacturers under OEM brand names. Through the experience of cooperating with the top level manufacturers, Supertec Machinery has gained lots of useful techniques and skills.

By 1997, the Chu family’s business had grown firmly worldwide; at that time Mr. Randy Chu decided to establish Supertec Machinery Inc. in Los Angeles, with the goal to enhance the service and technical support between US manufacturing and the machine tool supply chain in Taiwan.

In 2010, in order to address the demand for precision grinding operations and productivity optimization in the US market, Mr. Randy Chu set up the technical & application headquarters in Taichung, Taiwan. Now with Supertec Machinery having decades of experience, the customers can easily order “customized” or “turn-key” grinders that can be installed on their production line without unnecessary time delays.

For over 20 years Supertec Machinery Inc. has accumulated trust and support from customers all over the globe. We are grateful for having opportunities to serve our customers. In 2022 Supertec Machinery will continue our investment in sustainable manufacturing operations, in order to keep providing the best quality of products and service to our customers!
