Uniformly high quality – always
Our internal quality assurance ensures that the series production meets the set quality standards. We ensure the quality and precision of the parts with visual inspection and by using a video measuring system. We also mark the production batch number on the packaging for ex-post monitoring.
We perform water cleaning with an ultrasonic method on all sheet metal parts before shipment. The cleaning is performed in accordance with your needs; on the production line or separately.
Production series tool manufacturing, maintenance and testing
Our tools department designs and manufactures all special tools needed for sheet metal production by using the latest production methods and high-quality materials.
Maintaining and testing the tools is also an important part of our business. We produce the agreed amount of customer products by using product-specific materials, from prototype parts to production series.
We build the production lines with the help of a Finnish supplier specialised in automation equipment.
