About

25 years of experience

who we are

Sumipro was founded in 1995, starting with the manufacturing of special contact lenses with Single point diamond turning. In the early 2000s, technical optics began to have considerable impact on our services. Over the years, technology has revolutionized our world. With our knowledge, experience and cooperation with our suppliers we try to create solutions for our customers which have an extra added value through innovation and application of state of the art design and production facilities.

In 2005 Sumipro moved to our current location in Almelo. In 2012 we added optical coatings to our services. These facilities have been completely modernized in 2019 and is fully automated. During the years we have created a proven track record of helping our customers with fast delivery and a flexible attitude.

Programming

Preparation of production files

Sumipro is prepared to work with many different filetypes or drawings. We always look for a way to achieve the best results for your products. If you’re unfamiliar with CNC (Computer Numerical Control), it enables our diamand turning machines to transform computer-based designs into G-Code. G-Code is a programming language made up of letters and digits and tells our CNC machines where and how to move. Using what are called Cartesian coordinate locations, the machine is fed instructions including direction, speed and depth, enabling it to create products from a computer image.
If your files are not delivered according to our specifications, we have to convert them to usable files but there are additional programming costs involved.

Files for quotations

For quotations we only accept technical drawings to make sure all features of a product/component, including surface roughness, dimensions and quantity are known. This is the only way to calculate a realistic price for the required product.
