Open-Air Plasma Treater Is Cheaper, Faster

December 2001, St. Louis - A small, open-atmosphere plasma-treating system is designed to replace popular flame treating of small plastic parts before painting.

Model LT-2000 from Lectro Engineering, St. Louis, runs parts through a tunnel where it creates a cold plasma at atmospheric pressure. Compared to a standard plasma treater, the LT-2000 is said to be 66% smaller and about 50% faster, and it sells for $35,000 to $40,000 versus $100,000 to $150,000.

While plasma systems are more costly than flame treaters, they do not heat parts, so they do not warp and their cosmetic integrity is preserved. Also, the LT-2000 requires no adjustments when changing the product being treated.
