SAM chooses Vetaphone for surface treatment
Korea’s Sung An Machinery (SAM), a manufacturer of extrusion, coating and laminating technology, has invested in Vetaphone corona treatment technology for its recently opened test lab.

Founded in Seoul in 1960, the company began by manufacturing rotogravure printing presses before moving into extrusion coating in the 1980s. Now managed by the sons of founder M C Shin, D H Shin as chairman and D S Shin as CEO, in 2000 the company was accredited with ISO 9001 and moved premises to its current site in Mado and set up a new R&D centre. With UL registration obtained, SAM began selling into the US market in 2008, and two years later established SAM North America LLC in Fulton, New York. Today, the company has four locations, two regional offices, agents in 26 countries and sales representation in 32 more.
As demand for the company’s technology grew, a test lab facility for coating and printed electronics was opened at the Mado complex in Korea in 2016. It was here that SAM first took an active interest in Vetaphone technology, which is now used for surface treatment technology across a variety of substrates, from PET to BOPP, aluminum foil and metalized film.
Joon Shin, grandson of M C Shi, said: ‘We were first made aware of Vetaphone by a customer, but it was only when we began to investigate the best technology for our test lab that we came to understand the depth of knowledge that Vetaphone offers because it is the company that invented the corona treatment process.’
The Solution Coating Lab into which the Vetaphone unit, a single-sided 16KW model with 25W output and fitted with a conductive ceramic coated backing roller, has been commissioned is designed for customer product development trials and coating research, and offers solvent- and water-based, as well as UV and 100 percent solids, coatings opportunities in a clean room environment.
Joon added that one of the key factors in his company’s decision to choose Vetaphone was the advice and support it provides on a global basis. ‘We are an international provider of sophisticated technology, with over 600 machines installed in more than 30 countries, so it is vital that we work with suppliers that can match this global coverage with a commitment to after sales support.’
