Stiff polyurethane, an excellent alternative to steel sheet

Stiff polyurethane appears to be an excellent alternative to steel sheet when designing outdoor and indoor multimedia totems.
RGS has been operating in the sector for years, placing its 20 years of knowledge of the raw material and its experience in design and planning at the service of its customers.

The two examples given below refer to two info points that differ in terms of materials used and design for the purpose of meeting customers’ specific requirements.

OUTDOOR INFO POINT
For this outdoor project, we have chosen to use polyurethane only for the central panel of the totem. This gives the user a functional and ergonomic interface with the device, while the use of steel sheet guarantees the required sturdiness with a reasonable investment. For this item, we have used Baydur 110 with ribbing on the backside to make it highly resistant to mechanical stress and shocks, including acts of vandalism. The design of the mould with 3 removable dies evidences the flexibility of stiff polyurethane technology. This allows implementing diverse solutions for those customers who require enhanced user interfaces. Special attention is paid to the seat of the gaskets between polyurethane and steel sheet, designed to guarantee a tight seal and therefore protect the totem as much as possible from the elements. Inside the enclosure there are numerous threaded inserts that allow installing electronic components directly in the polyurethane panel.

INDOOR INFO POINT
A nice example of technology conversion from steel sheet to polyurethane. Polyurethane has solved the main problems of the previous steel sheet production both in terms of delivery times (keeping pace with demand) and assembly, which is much simpler and therefore offers substantial economic advantages.

info-point-kit-artuBesides the economic aspect, the design and ergonomics of the totem have been the object of great care. The peculiarities and formulations of stiff polyurethane 110 and 60, both in the certified self-extinguishing version, have been fully exploited.
Baydur 110, as previously remarked, was used to stand shocks and mechanical stresses, and Baydur 60 for thicker aesthetic details to favour ergonomics and design (complying with design features that require higher thicknesses). The use of aluminium moulds with removable dies has made it possible for us to obtain different shapes, in particular for the door for which, instead of 4 different moulds, we have conceived a single mould with 4 removable dies to create 4 different shapes and thus meet specific requirements with substantial cost savings.
Last but not least in terms of visual impact, the aesthetic finish on a stiff polyurethane item: beautiful, strong and pleasant to the touch.
