In each production process, fierce competition exists between those who designed industrial robots, often relatively unsophisticated, for particular production processes and the universal robot makers who
offer playback and intelligent robots. In most

In plastic molding (the automatic unloading of injection molded products) the small manufacturers dominate. Ichikoh Engineering Co. and Kyoshin Electric offer a complete line of fixed sequence machines. Star Seiki offers both fixed and variable sequence robots. Sailor Pen, likewise, offers relatively unsophisticated machines. For unloading workplaces from a die casting machine, Ichikoh offers its fixed sequence machine while Shoku and Daido offer variable sequence robots.
For putting workplaces into a furnace Shinko Electric has a relatively sophisticated variable sequence robot. Nachi Fujikoshi offers a specially designed robot to tolerate hot temperature which has bee n used to transfer workplaces from a furnace to a press.
In the forging area, a great number of
robot makers offer Komatsu and Nachi
