Low-cost wood is still king, but plastics’ reusability is a growing attraction among manufacturers looking for sustainable material-handling options. The one major hurdle is today’s high resin prices.
Manufacturers and users of plug-assist tooling have a new technique to improve the surface finish and cycle time of thermoformed parts.
Rapid prototyping (RP) equipment is increasingly being used to manufacture prototype and short-run production molds for blow molded and thermoformed parts.
New cost-effective technologies are designed to make aluminum an attractive alternative to tool steels in a range of plastics molding processes. One method uses a plasma technique to convert the aluminum surface into a hard, dense, wear-resistant ceramic. Another approach uses electro-deposition to apply a surface coating with high hardness, corrosion resistance, and chemical resistance.
There was plenty of news in thermoforming at K 2007 as suppliers rolled out continuous roll-fed packaging systems with greater output, enhanced cooling, reduced air consumption, and more automation.
The industry’s largest twin-sheet thermoformer and the first North American source of halogen heaters were among the machinery and equipment developments at the recent 17th Annual SPE Thermoforming Conference in Cincinnati.
Chain branching opens up lots of new processing opportunities for these fluoropolymers.
A new version of in-mold decorating technology, developed initially for exterior auto body components, uses dual-cure coating technology to provide a paint film that is both stretchable for good thermoformability and also provides the high gloss and durability of conventional paints.
