Raw material
We have specialist knowledge and experience of different materials and their characteristics. This knowledge is put to use both in product development together with our customers and in our production. Today, we produce parts in materials including titanium, zirconium, hafnium, stainless steel (e.g. 316L, super duplex) and inconel. We have well established procedures for storage, handling, quality assurance and full traceability from raw materials to finished product.
Metal cutting
Ever since the beginning in 1956, Willo has been distinguished by its specialist expertise in metal cutting. This forms the basis for what we now call Willoprecision – small, difficult critical parts. We maintain these skills by being at the leading edge of knowledge about new manufacturing methods and modern machinery.
Grinding
In our grinding department we handle parts with dimensions down to +/- 0.001 mm and/or Ra values of 0.02. It is important for us to also be able to take responsibility for this part of the production process.
In our grinding department we handle:
Surface grinding
Cylindrical grinding
Centreless grinding
Internal grinding
Plunge-cut and through-feed grinding
Superfinish
Honing
Lapping
Measurement
Verifying the tough requirements for the parts we manufacture is an important component of our work. In our temperature-controlled measurement room we have advanced programs which give detailed information about the product and a complete measurement history.
The measurement results are filed in accordance with our own and our customers’ stipulations.
Cleaning
All finished parts are cleaned carefully at one or more stages in the process.
There is a secondary alkaline washing process primarily for nuclear power parts, and a separate wash for medical technical products so that they can achieve the approved level of cleanliness for class 8 clean rooms.
Packing
Packaging is done both in customer-owned wrapping and in specially produced wrapping which gives the product optimal protection during delivery. We also carry out final packaging of parts which go directly to
the end customer, which requires knowledge of labelling with the right design to follow the customer’s directives.
Logistics
We work with many different kinds of logistical solutions, depending on our customers’ needs. Optimal customer agreements, high delivery precision and quality, correct documentation, short lead times and flexibility are important watchwords for us at Willo.
