Fastening/Joining/Assembly

Snap rivets

No-tool installation

This line of snap rivets has expanded its size range to feature a 0.25-inch diameter hole and panel thicknesses from 0.07 to 0.39 inch, as well as other offered sizes. The two-piece fastener is molded in high dielectric (UL 94V2) Nylon 6/6 and can be installed without tools. According to the company, when the rivet is placed in the hole and its oversized head pressed in, the legs expand and lock components in place. Micro Plastics Inc.www.microplastics.com Enter 646

Adhesive

Simplifies automation of ungapped cores

Multi-Cure(R) 621-VT one-component adhesive cures at room temperature in 1 to 10 seconds upon exposure to the company's BlueWave(TM) 200 spot light curing system, which eliminates the need for cool-down time, ovens, and the handling that comes with heat cure epoxies. When chemically cured for high-strength bonding, the adhesive cures in 30 to 60 seconds, and low viscosity activators may be sprayed or applied with felt pads when interfacial bonding is required. Able to cure with visible and UV light, it may be used in dc motor-assembly uses like strain relief, flange attachment, motor sealing, and wire unitizing, as well as ferrite and metal bonding applications.

Bonds low energy surfaces

Bond-Ply 400 un-reinforced, thermally conductive, pressure sensitive adhesive tape features reportedly high bond strength during long-term exposure to heat and high humidity. Made with strong wetout characteristics and thermal performance to supported materials, the adhesive tape may be used in securing heatsinks and heat spreaders to BGA graphics processors, computer processors, power converters, and motor control PCBs. The tape comes with easy-release protective topside tabs and is available in roll form, sheet form, and die-cut parts. The Bergquist Company www.bergquistcompany.com Enter 648

Needle bonding line

Prevents fluid leaks

This needle bonding line consists of 18 products, divided into light cure acrylics, light cure cyanoacrylates, and one-part heat cure epoxies. The products feature reportedly fast cure times and high needle pull strengths, and are highly fluorescent for automated in-line inspection. The adhesives are designed to bond cannulae to hubs in needle assemblies and to keep fluids from leaking from the needle assembly. The 13 on-part, solvent-free light cure acrylic adhesives have viscosities from 150 to 10,000 cP, with cure depths over 0.5 inches. The two light cure cyanoacrylate adhesives come in 20 and 900 cP viscosities, and the three one-part heat-cure epoxies, available in three viscosities, provide high adhesion, environmental resistance, and good sterilization.

With a working temperature of 900C, the quartz parts assemble easily due to thermal expansion mismatch. Applications include optical cells, transducers, scientific glassware, lamps, assembly lasers, and other optical and electronic devices. Vitta Corp., www.vitta.com Enter 650

Grommet sleeve

Prevents wire chafing

The Richco Grommet Sleeve (RGS) series offers support for wires and cables passing through panels and complements the company's line of grommets and bushings. Made of flexible PVC, the grommet snaps into the hole panel and the cable or wires are then fed through the grommet. The grommet sleeve also may keep the wires from chafing against rough panel hole edges. Grommets come in 13 sizes and four styles to accommodate different cable sizes, hole diameters, panel thicknesses, and applications. Richco, www.richco-inc.com Enter 651

Polyurethane tubing

Low compression, natural flexibility

With no plasticizers to contaminate critical streams, Superthane(R) brand transparent polyurethane tubing combines the high tensile and elongation values of rubber with the abrasion and tear resistance of plastic. The tubing is engineered to provide chemical resistance, durability, and good weathering for use in oil and fuel supply, air and gas lines, insulating sleeves, fluid feeds, nuclear power facility uses, and powder and granular transfer. The tubing is available in an ether-based version for moisture resistance and an ester-based material for resistance to most oils, gasolines, kerosenes, and other petroleum-based chemicals.
