MAAC Machinery, established in the early 1950 s in Chicago, developed and named what is known today as the standard thermoforming sequence techniques. The company pioneered and wrote the design standards for motorized platens, gas and electric ovens, fully automatic sequencing, all aluminum clamp frame, pressure forming and twin sheet pressure forming. MAAC s approach to building a standard third generation Chicago style machine with a similar motorized platen design quickly made it the fastest growing United States manufacturer of sheet fed thermoforming machinery. MAAC operates under the same ownership and business practices that brought it to the forefront of the thermoforming industry. The company s increased size and major investment in new facilities and manufacturing systems has given it the lowest manufacturing costs and shortest delivery times in the industry. MAAC Machinery s corporate offices and manufacturing facility are located in Carol Stream, Ill.
