Additives are an area where design engineers could focus a little more time and attention. When added to plastic resins, these chemicals impart a needed property and they also change the mechanical characteristics of the compound. There are also new technologies emerging that can save time and money. One I saw recently comes from Carolina Color of Salisbury, NC. A new process creates so-called “super concentrates”. “G2 has overcome processing challenges with a proven ability to provide exceptionally effective dispersion and distribution in both large and small parts,” says President Matt Barr. The new G2 product line is claimed to save up to 30 per cent in color cost and allow processing at lower temperatures, which can save up to 10 percent in cycle time. Part thickness can even be reduced because of improved physical properties. That also means reduced cycle time and clamping force. It’s worth a look.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
