Introducing The Protomold® Torus: A Complex-Feature-Demonstration-Sample

Proto Labs Ltd. Shropshire, UK. September, 2010: Following the extraordinary success of the Protomold^® Cube Resin Puzzle and Demo Mould feature-demonstration samples, Proto Labs^® has created The Protomold Torus: a new colourful, educational tool, available to designers and engineers, providing them with a handy and instant reference to the most commonly used features in injection-moulding – demonstrating that just because you want a part fast doesn’t mean a part has to be simple.

Geometrically, a torus is a surface generated by revolving a circle in three-dimensional space about an axis coplanar with, but not touching the circle. Made up of three, separate sections that fit together to form a doughnut, each one has several unique features to illustrate some of the more complex geometries achievable with injection-moulding in a part design. Section A, for example, shows a bayonet mount, text on a rib and several types of spring-clip; section B shows a gear, a ‘bumpoff’ and two types of bosses; and section C shows a clip, a clip dimple, text on a side and an energy director on a pocket. The Protomold Torus comes with a fully illustrated booklet explaining how the different features are created and an indication of relative cost of including them in a design.
