Mold system captures many surface textures
International Mold Steel Inc.'s Espor is a new castable mold system that allows economical surface textures in vacuum forming and thermoforming.
Espor is a combination of aluminum powder and epoxy resin. A mold maker starts with a rigid, solid pattern made of wood or other materials, and pours Espor onto it. When it hardens, the Espor gives a precise reverse impression of the pattern. Leather grain and other features can be built into the mold more economically than with a solid aluminum mold.
The Florence, Ky., firm said Espor exhales throughout its entire surface, allowing reproduction of the surface pattern during sheet forming.

3M adhesive replaces fasteners for savings
3M Co. expanded plastic bonding applications with its new Scotch-Weld structural plastic adhesive DP-8005.
3M said the new adhesive can eliminate fasteners and rivets to save cost and time and to improve aesthetics of plastic constructions. The St. Paul, Minn., company claims DP-8005 can bond polypropylene, polystyrene, thermoplastic elastomers and other hard-to-bond materials to each other and to metals, concrete, glass and wood.
Scotch-Weld DP-8005 is solvent-free. 3M's EPX hand-held applicator accurately meters, mixes and dispenses a two-part adhesive from 3M's Duo-Pak cartridge for consistent bond quality and less waste. The adhesive takes three minutes for green cure at room temperature.
