Insert molding design kit
One manufacturing method that has been growing in popularity groups discreet components into a custom-built mold and encapsulates them together with thermoplastic to create a single unit, reducing the time and possible mistakes that may come during hand assembly. From its earliest applications with the now-ubiquitous wire-plug connection on power cords, the insert molding process can now be found in electrical connectors, sensor and switch assemblies, and filter elements. This company, specialists in insert molding, is offering a multi-page booklet discussing the process and its applications. Of particular use are discussions regarding materials, capabilities, and design parameters one must understand when considering the use of insert molding.

Glass & quartz tubing
This company fabricates micro-inch tolerance Precision Bore (PB) glass and quartz tubing using vacuum heat shrinking methods. Stainless steel and molybdenum mandrels provide ID tolerances to ±0.0002 in. Design assistance is available, including shrinking, glass-to-metal sealing, concentric and centerless grinding, and polishing to achieve finishes below 2 microns. Wilmad/Lab Glass, Buena, NJ.  www.rsleads.com/212df-228

Weather-resistant steel
Hot-rolled Domex 100W (100 minimum yield) is manufactured with 0.118- to 0.236-in. thickness, while cold-reduced Docol 100W is between 0.0197- and 0.079-in. thick. A weather-resistant 2-year old oxide layer impedes corrosion-inducing moisture at 4 to 5 times the resistance of conventional steels, while the extra high strength reduces dead weight.

Liquid silicone rubber
This company now offers off the shelf and custom formulated Liquid Silicone Rubber (LSR) and platinum-cured Room Temperature Vulcanization (RTV) products. Both LSR and RTV compounds are offered in a hardness range of 5 to 80 Shore A and a viscosity range of 1000 to 7,000,000 cps. Formulations include varying cure rates to optimize cure efficiencies and extend shelf life, as well as custom coloring. CRI-SIL, Div. of IMMIX Technologies LLC, Biddeford, ME.  www.rsleads.com/212df-231

Mica cable tapes
This full line of asbestos-free high-temperature silicone bonded mica tape allows electrical cables to function while exposed to flames up to 2100°F. It is impervious to water, resistant to radiation, acid and alkaline, and is chemically inert and non-toxic. Central to the design is a magnesium-containing Phlogopite mineral that in conjunction with the silicon elastomer aids high-temp electrical insulation. Cogebi Inc, Dover, NH.  www.rsleads.com/212df-232

Multi-component elastomer cure system
Designed for this company’s Tufel II elastomers line, this cure system consists of the IN-7 inhibitor and CA-7 platinum catalyst masterbatches. The 2-part system allows operators to balance product cure speed and shelf life to accommodate specific equipment requirements and extrusion profile configurations in the production of thick-walled tubing. GE Silicones, Waterford, NY.  www.rsleads.com/212df-233

Gasketing & sealing material
This company introduces a line of gasketing and sealing material for applications including NEMA 4, EMI/RFI and UL. Compression gasket materials include EPDM material with NEMA 4 sealing and UV resistance, UL 94 flame-retardant neoprene closed-cell sealing tape with adhesive backing, UL 94 PVC, and EMC conductive fabric bonded on EPDM compression gasket profiles. Dirak Inc, Chantilly, VA.  www.rsleads.com/212df-234

Low-friction micro-coating
The MicroBlue coating system provides a uniform 1-micron thick layer that reduces friction, even in non-contact environments. Treated surfaces can withstand load forces in excess of 300,000 psi and will not chip, flake or peel. Since heat is not required for curing, no metallurgical change occurs with application. The coating has a dynamic cf of 0.030 and it withstands temperatures between –400° and 1000°F. Material Technologies Inc, Rockford, IL.  www.rsleads.com/212df-235

Hardsurfacing alloy
Specifically developed for high impact and abrasive applications, 80PTA hardsurfacing alloy contains 60% abrasion-resistant tungsten carbide particles (3500 DPG) in a soft (HRC30) impact-resistant nickel base matrix alloy. Particles are uniquely matched so that a high volume percentage of carbide grains is uniformly distributed throughout the matrix alloy.

Application Xtra

Yellow colorant
PV Fast Yellow H9G is an intense green-shaded yellow that can be combined with other pigments to produce a wide range of shades. It displays excellent heat stability, light fastness and alkali resistance, and it exhibits low influence on warpage in HDPE. The offering is suited for coloring polyolefins, PVC, styrenics, PMMA, POM and PP for spin dying. It is FDA-compliant for food contact packaging. Clariant Pigments & Additives, Coventry, RI.  www.rsleads.com/212df-237

Conductive plastics
The Premier line of conductive thermoplastics for EMI shielding and grounding in electronic devices features a proprietary dispersion of long, nickel-plated carbon fibers in a choice of resin matrices. Even dispersion of randomly oriented fibers permits integration of shielding into housings without additional processing steps such as plating, painting or vacuum coating. EMI shielding is greater than 90 dB. Chomerics div of Parker Hannifin Corp, Woburn, MA.  www.rsleads.com/212df-238
