Spinner hanger blast machine produces eight times faster processing times

Improved quality and lower costs through automated shot blasting operation

- Doris Schulz

The lack of flexibility and unsatisfactory powder coating qualities at external job shops induced a Dutch manufacturer of industrial furniture to bring its coating operation in-house. Unlike its competitors, the company decided to also do the paint preparation by shot blasting in-house with an automatic shot blasting machine from Rösler (rosler.com). Compared to manual processes, the shot blasting cycle times are not only eight times faster, but the automatic solution also produces better qualities at lower costs. This resulted in a significant competitive advantage.

ML Constructie produces small tools and industrial furniture. In addition, the company serves other manufacturers with a laser cutting service for sheet metal, tubes and semi-finished products. In the past industrial furniture was generally sold without any protective coating. However, in recent years customers increasingly demanded the furniture to be painted. Due to the rapidly growing demand for color coated products, the company initially had the shot blasting and powder coating of the furniture done by external job shops. Ben Luizink, co-owner of ML Constructie, reports: "We were not satisfied with the handling of our work by the external job shops. Due to long lead times we could not deliver our products as quickly as we wanted. Moreover, most of the time the coating quality did not meet our specifications. For example, we found residual sand from the sand blasting operation on our products. And the coating thickness was generally insufficient. To better control the blasting and coating operations we created our own in-house coating department." That's how a few years ago ML Coating was started. Since then it has grown into a coating company that shot blasts and powder coats its own products and provides blasting and coating services to other companies.
