We make many of our pieces using the lost wax casting method, a technique that has been in use for thousands of years. In this process an original model is made in metal or hard wax. A rubber mold is made of the carving and molten wax is injected into the mold to make a perfect wax replica. Several wax replicas are then arranged on a central wax core to make a tree which is then immersed in a plaster-like material. The hardened plaster casing is heated over a long period at high temperatures until the wax inside vaporizes. Whats left is a hollow mold into which molten silver or gold is poured. Once the metal cools, the mold is broken open […] Continue Reading…

Pultrusion with resin transfer molding (RTM) Rainer Eberle Zürich University of Applied Sciences, Austria The name pultrusion combines the words, “pull” and “extrusion”. Pultrusion technology represents the only method currently capable of producing automatically structural composite parts on a continuous basis and of unlimited length. In the pultrusion process, reinforcing materials in the form of dry unidirectional fibers, woven or non-crimp fabrics are continuously pulled from creel racks. This collation of dry reinforcing fibers then passes through forming cards, before entering a heated steel mold. Resin is applied to the preform, either by pulling through a wet-bath or by injecting the resin directly into the die. Due to this pulling, the fiber filaments are in tension when curing in the heated die. While in tension, the fibers have higher strength values and are more aligned, allowing good compaction and more fibers fitting into a given gravity. The mold forms and compact the material into the final geometry. A pair of hydraulically-activated gripping plates is used to alternately grab and pull the material through the system at a constant speed. The profiles then periodically cut with a cut-off saw. Human interface, for example by hand-lay-up is eliminated and therefore the […] Continue Reading…

GF/ISB series adopts the world’s most advanced “single-stage injection stretch blow” molding technology. One single machine is able to achieve high quality and efficient productivity.

This is an ABAQUS simulation of the stretch blow moulding of a drinks container. The animation details the stretching of a Polyethylene terephthalate [PET] pre-heated preform using a stretch-rod, followed by the high pressure air inflation process to form the receptacle in a mould. The legend in the upper left hand corner of the video is a contour of the material thickness distribution [STH] in the wall of the container. For further information please contact Dr. Gary Menary PhD at the School of Mechanical and Aerospace Engineering at Queen’s University Belfast.

The analysis was performed using Bulk Flow Analyst™ from Overland Conveyor Company. In the slush molding process, plastic resin is rolled about inside a volume consisting of a powder box and a tool. The tool is heated, so as the particles come into contact with it, they melt and become stuck to the tool. Using this process, users can find out what rocking and rolling sequence gives adequate coverage to the finer details of the tool. www.applieddem.com www.overlandconveyor.com

Slide Products demonstrates how to properly lubricate ejector pins for injection mold machines. Demonstration includes using aerosols and non-aerosol lubricants, using the best lubricant for the front and back of the pin, and lubricating pins in the injection molding machine.

MythBusters co-host Adam Savage gives a fast-paced presentation on personal obsessions. Savage explains how his fascination with dodo bird skeletons eventually led to his designing of an exact bronze-cast replica of the titular statue from the 1941 Humphrey Bogart movie, “The Maltese Falcon.” —– Adam Savage speaks at the 2008 Entertainment Gathering in Monterey, California. This program was recorded on December 12, 2008. EG is the celebration of the American entertainment industry. Since 1984, Richard Saul Wurman has created extraordinary gatherings about learning and understanding. EG is a rich extension of these ideas – a conference that explores the attitude of understanding in music, film, television, radio, technology, advertising, gaming, interactivity and the web – The Entertainment Gathering Adam Savage has spent his life gathering skills that allow him to take what’s in his brain and make it real. He’s built everything from ancient Buddhas to futuristic weapons, from spaceships to dancing vegetables, from fine art sculptures to animated chocolate — and just about anything else you can think of. The son of a filmmaker/painter and psychotherapist, Adam has been making his own toys since he was allowed to hold scissors. Having held positions as a projectionist, animator, graphic […] Continue Reading…
