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.
