Design & Development

A Day in the Life… Design & Development

Liniar’s Design & Development department is, in many ways, what makes us the innovative, ground-breaking company that we are. Taking ideas from concept to creation is only part of the work that they do however – keeping manuals up-to-date, testing, quality assistance, management of the WER database and dealing with customer enquiries are just a few of the duties they undertake.

Liniar Design and Development Department

Each day is different, but a typical day might include the following…

Product Design

Product design is at the very heart of what we do, whether it’s taking an existing industry product range and improving it in every way we can, or a brand new innovation that often starts off life as a ‘fag packet sketch’.
Designs are brought to life using AutoCAD for 2D work, Solidworks for 3D modelling and rendering and our 3D printer for bringing prototypes to life.

Product Development

There are many ways we develop the range of products that Liniar has to offer. Updating fabrication manuals with new products, assisting manufacturing departments with quality control and focusing on how we can make the products we supply to our customers some of the best in the industry. We have several members of our team who are trained to work with Mark II, our articulated robot, and together they put many of our products through their paces, helping us to develop products even before launch with accelerated life cycle testing.

Customer Support & Technical

The design and development department have a very strong link with our technical department, working closely to gain feedback from customers and independent testing to ensure all this experience is focused back into the development of our products. We are always free to call when there are queries on anything from product manufacture to energy ratings.

Window Energy Ratings (WERs)

A daily task within our department is managing our WER database that feeds the Liniar website and updating it with new simulations upon customer requests and changes in glass and spacer bar construction.

Members of our team attend quarterly meetings in London to keep their simulation training up to date and ensure we can provide our customers with the greatest possible service when it comes to energy ratings.

The colourful A, B, C rainbow scheme we are all familiar with is simple to the end customer, but it’s a complex set of procedures behind closed doors.

Designing and developing new products is only half the story and it’s just as important communicating with our customer base and the fenestration industry about any new product releases or updates.

With this in mind members of our team spend painstaking hours generating renders and illustrations to accompany technical bullet points that feature within the marketing departments wonderful creations. It’s pointless having a great idea if nobody knows about it!

Exhibitions are also an exciting time where the combination of the engineers within the design department and the creativity of the marketing department get to showcase ideas to our public, with amazing results.
