701E31 Workshop Equipment

Plaster drying oven

Efficient plaster drying combined with high quality

The new Ottobock plaster drying oven is like no other in the world. It can dry plaster models faster and more energy-efficiently using the principle of condensation. As a result, orthopaedic workshops can substantially reduce the costs incurred during the fabrication of orthopaedic components such as prosthetic sockets. At the same time it features high-quality workmanship, functional design and more convenience.

Success through a shorter drying time

The drying time is reduced by almost half! A comparative test has shown that the new plaster drying oven takes only 13 hours to dry test plaster models. By contrast, the infrared convection oven requires a drying time of 24 hours for the same quantity and the same material.*

Positive feedback from practitioners

"The new oven dries much faster," says Gerben Dokter, workshop manager of the orthopaedic company Gardeslen. "We can have our plaster models dried in just one night – every night. Our weekly planning is now considerably more flexible and we save time."

*The comparative test was carried out on six plaster models made of alabaster modelling plaster with a weight of 4 kg each and a plaster-to-water mixing ratio of 1:1.5.

A conversation with Workshop Manager Gerben Dokter

Gardeslen, an orthopaedic technology company in the Netherlands, had its entire workshop re-equipped by Ottobock Planning & Equipping in 2016. It has now acquired Ottobock’s 701E31 plaster drying oven in addition to the existing convection sheet heating cabinet, which was previously used for heating synthetic materials as well as for drying plaster models.

Gardeslen’s Workshop Manager Gerben Dokter speaks with Christoph Neugebauer, the head Product Manager at Planning & Equipping, about the changeover to the new equipment and the key benefits of the new plaster drying oven.

Is drying faster in the new plaster drying oven?

The new oven does exactly what we hoped for: it dries much more quickly! We can have our plaster models dried in just one night – every night. Depending on the size of the plaster model, many models are already dry the next morning and ready for further processing. With the new plaster drying oven, we are now able to process plaster models during the week as well, which makes our entire schedule for the week more flexible.

What was so complicated about the old sheet heating cabinet?

With the old sheet heating cabinet, we could only dry plaster models over the weekend because drying took so long for starters, and secondly because the heating cabinet was already used to capacity from Monday through Thursday for heating thermoplas-tics. This meant we had to plan plaster drying every Friday for an entire week in advance.

What are the benefits of the new oven’s design?

The new plaster drying oven has three levels we can use for drying plaster models. This saves us space, and we have more room for our plaster models than ever before. Finding room for all the models in the sheet heating cabinet was really tricky.

Is the new plaster drying oven more convenient to use?

Yes, definitely. It’s very easy to control with the touchscreen, and we can save energy by using the eco mode. I find the timer on the device very efficient, for instance. It lets me set up to 20 individual drying times with alarms – so every plaster model gets the right amount of time.
