About us
More than 30 years of experience in materials processing
HWI Machining is a family business with over 30 years of experience. We have been machining materials at a high level since 1991: turning, milling, boring and sawing. We also design, assemble and test products, with custom work where necessary. Always accurate and certified. Curious about what we can do for you? We would be happy to tell you.
Our vision
At HWI Machining, we have a clear vision of machining and manufacturing materials. These need to be manufactured accurately, as smartly and cost-effectively as possible. Because we can carry out the entire production process - from design to quality control - in-house, we can serve a broad target group. We look at applications and solutions with an open mind and, where necessary, think along with you about the right techniques. Where possible, we also make the production process more sustainable and efficient. Together with our customers, we take the manufacture of complex and high-quality products to a higher level.
