Mentec World. Co., Ltd. is the company where maintenance engineers are gathered with a history in which we have supported the production line for over 40 years with the "maintenance-free spirit (reduction of maintenance cost)" as a primary corporate company of the major automakers in Hiroshima and Kyusyu. With a pioneer spirit and engineer spirit, we have developed the "overall efficiency" business in plant to deal with various kinds of situations such as cost, quality, safety and health based on "TPM (Total Productive Maintenance)" for 21 century. We have actively taken part in the "environmental business" by making use of the experiences obtained from the actual results of maintenance. One of the activities is to produce the "Dust buster" and "Mist net" which inhibit dust with "bubbles" or "mist" to improve the working environment of the stone pit, intermediate treatment facility, iron work, demolition yard, or other sites. Producing and selling them were started 12 years ago, and now approximately 200 units are working in the world to improve the poor working environment because of dust in various kinds of markets. Also, our "Spiral duct" featuring low cost, size free, light weight, and high rigidity by winding the sheet metal coil in continuous spiral and connecting with caulking has been used in the various kinds of fields such as air conditioning/ventilation equipment for 40 years since the production was started.
