Tri-Tunnel® is a dust-free environment designed to improve quality and reduce costs and is a leading choice of America's automotive paint shop industry. Scion, in partnership with Concord Industrial Corporation, will develop a custom Tri-Tunnel® Plastic Enclosure System to your specifications. In the late 1980’s, competitive pressures in the automobile industry called for higher quality finishes with reduced manufacturing costs. OEM’s and their suppliers needed an enclosure product that would keep cars and components free from dust and contamination between paint processes. Highly effective yet economical, the Scion Tri-Tunnel® Plastic Enclosure System was developed and patented (Patent No. 5181354) in response to this need.
