Pre-drilled shafting
This tubular steel shafting is composed of the company’s 60 Plus 52100 material. Predrilled and tapped every 8-in., they are available in 1½- and 2-in. dia. up to 12 ft long. The shafts can be supplied with or without support rails and shaft assemblies (fully mounted). Tubular shafting provides more strength and rigidity per unit of mass than comparable solid shafting. Another benefit is that it cools down more quickly than solid shafting, thereby extending the life of slide bushings operating at high load and high speed. These shafts can be used as conduit for electrical control lines, pressurized air lines for pneumatic devices, or hydraulic lines. In high speed manufacturing operations, for example, these lines would be less susceptible to rupture or damage when protected in this manner.

Post-mold fluorination sealant
Designed to replace expensive alternative materials with surface-modified plastics, this post-mold fluorination process exposes the surfaces of plastics (and other materials) to elemental fluorine under strictly controlled conditions of time, temperature and pressure. A permanent fluorocarbon barrier seals both inner and outer surfaces to prevent chemical permeation and evaporation. Fluoro-Seal, Houston, TX. www.rsleads.com/307df-111

Application Xtra 

Resin transfer molding
This company’s multi-staged resin transfer molding (RTM) process produces high-quality fiberglass (FRP) parts. RTM involves placing a fiber preform in a matched mold tool, then injecting a thermosetting resin matrix into the closed mold cavity at low pressure. Dimensional tolerance of ±0.1 mm is uniform. Fiber content of 25~75% creates strong, lightweight product. Various finishes are available. Whitewater Composites Ltd, Kelowna, BC. www.rsleads.com/307df-112

Antique finishes
Designed for ornamental finishing requirements, Antique Black and Presto Black antique finishes are simple, scalable and environmentally safe. The processes include surface cleaning, water rinsing, blackening/oxidizing, water rinsing and highlighting/sealing. They operate at room temperature with mild solutions and require no ventilation. An Ion exchange system produces zero discharge in rinse waters. Birchwood Casey, Eden Prairie, MN. www.rsleads.com/307df-113

Foam grips
VynaFoam grips provide a velvet-like finish with the comfort of foam and durability of vinyl. The non-slip finish suits this product for critical grip applications.
