Injection molding is a process in which molten material is injected into an interior mold. When the material cools and hardens it takes the formal configuration of the cavity. Rotomolds can make hollow objects. Injection molds make solid objects.
Rotomolding, or rotational molding, is a process where raw material (usually in powder form) is injected into a heated, hollow mold. The mold slowly rotates on one or more axes to allow the softened material to disperse and adhere to the interior walls of the mold. The constant rotation helps to maintain an even material […]
Vacuum forming is a method of thermoforming. Sheet material (typically plastic) is placed in frame within the vacuum former and heated until malleable. Once the plastic has a desirable amount of pliability, it is pulled over the mold. Once in position, a vacuum is applied, removing air from between the material and form. This draws […]
A water-jet cutter maneuvers a focused high- pressure stream of water to cut a material. Cutting can be done using pure water or water with an abrasive additive material like garnet sand. Garnet sand increases the machines ability to efficiently cut through thicker materials and hard materials such as titanium. Water-jets do not generate heat. […]
The laser cutter uses an optically amplified beam of light as a cutting element. That laser can etch, engrave and/or cut non-metallic materials including wood, glass, film, fabric, and plastic. The laser can be focused, and the intensity of light increased or decreased for specific tasks. Cut performance (depth for example) can also be controlled […]
A CNC router is a computer controlled machine that is capable of cutting a variety of materials. It is conceptually similar to the hand-held router. The CNC router machine translates CAD models into ‘G-Code’. This code supplies instructive coordinates to the machine. The router moves across a gantry in the Y-axes and plunges in the […]
A CNC milling machine is a computer controlled machine that is generally used to plane material, drill holes, cut or carve materials. Each of these subtractive tasks do not involve rotating the work piece itself. The Milling machine acts in the X and Y directions while fixed to a moving Z axis arm.
A CNC lathe machine is a computer numerically controlled tool that rotates stock material about an axis of rotation to perform various subtractive operations. These include cutting, sanding, knurling, drilling, deformation, facing, and turning. Tools can be applied to the workpiece to create an object with symmetry about that axis.
L.O.M (laminated object manufacturing) is a process wherein a sheet material is cut to shape and successively adhered in layers to build a three dimensional object. Layers aggregate in the Z direction.
Most of us are aware that the world is drowning in plastic, but it can be hard to make sense of just how much is on the planet. We were invited by the Museum of Vancouver to produce a model visualizing just how much plastic is out there. The easiest way to visualize plastic is […]
