Rogan's Liquid Silicone Rubber Molding Capabilities
In business since 1934, Rogan Corporation is a leader in the injection molding industry, producing thermoplastic and LSR (Liquid Silicone Rubber) components and assemblies. Manufacturing LSR components is a rapidly growing segment of the business. Rogan is one of a few select manufacturers that offer Bondable LSR overmolding. This process involves the injection molding of a bondable-grade silicone directly onto plastic or metal parts, creating a single integrated component. LSR's heat, chemical, shock, and vibration resistance along with its sound-dampening characteristics have made it an ideal fit for integral seals and gaskets, waterproofing complex geometries and electronic interconnects, integral membranes, diaphragms, valves, and switch covers. (Photo showcases .008" thick fins bonded to a plastic tube.)

Firstcut CNC machining service adds steel, stainless steel material options

Did you think that Proto Labs' Firstcut CNC machining service was just all about plastics? Customers can now upload their 3D CAD model at Firstcut.com and select from several new metal materials for custom, quick-turn CNC machined parts in prototype quantities. Parts can be made in stainless steel (304/304L or 316/216L) or steel (1018 or 4140). These new materials complement an existing selection of soft metals (magnesium, copper, brass, and aluminum) and over 30 types of engineering-grade plastics.

Self-lubricating iglide semi-finished polymers provide more creative freedom for designers

With 80,000 machine components available from stock, polymer specialist igus offers the right part for almost any application. Now design, maintenance, and mechanical engineers who make special parts themselves can order the company's high-performance plastics as bar stock. igus has increased its range of maintenance-free bar stock materials to include its proprietary polymers iglide A350 and iglide J350, which are perfect for bearings and bushings. Blue iglide A350 is suitable for medium to high loads. The material also conforms to FDA guidelines and can withstand acidic environments, which means it can be used in the food industry. The highly wear-resistant polymer iglide J350 is suitable for rotational applications and is extremely low friction -- especially when partnered with steel shafts. Both materials handle temps up to 356 deg F.

Four-week lead time on Generation II Simotics 1FK7 servomotors

Generation II Simotics 1FK7 servomotors from Siemens feature seven shaft heights, Quick-Connect power connector, and high-accuracy 20- and 24-bit field-replaceable encoders in 10 styles, all combined with a four-week lead time beginning July 1, 2013. The Generation II servomotor offers three inertia versions: standard, high-dynamic for rapid acceleration jobs, and high-inertia for maximum smooth running. Designed for operation without external cooling, these servomotors provide users with 3x overload, 2.5 percent torque ripple, cross-profiling for easier mounting, plain shaft or keyway design, and three IP ratings with or without holding brake.

Honda engineer retools auto-body painting process

Honda engineer Shubho Bhattacharya was inspired to develop technology to reduce the energy needed to operate the auto-body painting system at Honda's manufacturing plant in Marysville, Ohio. Auto-body painting accounts for the most energy use in Honda's production process. With the help of his fellow associates, Bhattacharya conceived Honda's Intelligent Paint Technology, which has cut Honda's North American manufacturing CO2 emissions by about 10,000 metric tons per year and saves a considerable amount of energy daily. This is the first clip in Honda's new environmental short-film series.

Save time and money on large-scale, high-value parts and prototypes with Sciaky's Direct Manufacturing
Sciaky's Direct Manufacturing (DM) is the only large-scale, fully programmable means of achieving near-net shape parts via additive manufacturing made of titanium, tantalum, inconel, stainless steel, and other high-value metals. Starting with a 3D model from a CAD program, Sciaky's fully articulated, moving electron beam welding gun deposits metal, layer by layer, until the part is complete and ready for finish machining. Deposition rates typically range from 7 to 20 lb/hr, depending upon part geometry and the material selected. Sciaky's DM has a standard build envelope of 19 x 4 x 4 ft, allowing manufacturers to produce very large parts and structures with virtually no waste. This is cool to see in action.
