Rigid Polyurethane as an engineering material
Whereas today's designers have a wide choice of engineering plastics at their disposal, compact rigid polyurethane offers unique, often hidden benefits.
A smooth recess for the switch, a precision cutout for the removable specimen plate, and a shallow indentation for the logo are all accommodated without sacrificing style.
Rigid polyurethane will accept a smooth paint finish or as in this case a textured random dapple effect to add a little elegance.
For Alphamatic's spectacle lens cutter, rigid polyurethane is used for the base platform, front moulding and main top cover, each part having close tolerance interfaces and demanding shapes.

The application in a working environment demands a tough casing.
A minimal footprint with smooth lines was a key consideration in the design of the enclosure for CellMap, Bio-Rad's laser scanning Confocal Imaging System.
It consists of a subtle combination of polyurethane shapes and sand cast aluminium components.
The artistic concept is realised by complex shapes in rigid polyurethane, whilst the aluminium meets the heat dissipation requirements.
Eight components in polyurethane and two sand cast in aluminium were needed and production techniques at Norse Precision Castings, ensured tight tolerances at the interfaces.
Bio-Rad logos, contoured into the polyurethane, blend in well with the two-tone paint finish to complete the classic design.
The finish on Drake's Refresh range of voice communication modules uses different colours on the smooth finish for product variants.
As a leader in its field, quality is paramount, style a refinement, Norse Precision Castings of Bedford, responsible for manufacturing the enclosure in rigid polyurethane, inputs on both.
Polyurethane exhibits a high degree of precision on the recesses, coping well with the intricate hole patterns accommodating lights and pushbuttons, as well as low tolerance on warp and overall fit.
The "velvet touch" external finish with silk screen printing and internal metallic coating for EMC/RFI screening are used to good visual and functional effect, adding to, rather than restricting the artistic style and performance.
Norse Precision Castings is in the unique position of being able to offer plastic (rigid polyurethane) or metal (sand cast aluminium) without "fear or favour" - both economically in low batch production.
