Ferro designs hues for injection molding Ferro Corp. has developed metallic color concentrates that drastically reduce knit lines in injection molded products.
The Nimex line currently includes eight colors ranging from dark gray to light silver. The Cleveland-based company claims the concentrates eliminate the need to apply primers and liquid paint after molding, thus allowing cost savings.
Ferro said conventional metallic colors can align vertically during injection molding, creating surface lines of color on the finished product. Its Nimex colors distribute evenly in the barrel, allowing uniform coloration, according to the company's Plastic Colorants Division.

MicroCenter gauges small-diameter tubing
Extrusion Solutions LLC's MicroCenter measures small-diameter tubing, using a device with an adjustable opening, called a weir.
The company, based in Las Vegas, uses three micrometers to position the weir in relation to the extruder. The distance between the weir opening and the extruder, and the vertical and lateral position of the weir opening within the water bath, now can be controlled within 0.001 inch.
Before MicroCenter, the weir alignment was achieved by moving the entire water trough, which can disrupt the level and stability of the cooling water, according to the company.
The company custom-makes each MicroCenter to fit any water trough. A transparent Lexan mounting plate helps the user set the desired water level.
Extrusion Solutions rolled out MicroCenter in January, at the Medical Design & Manufacturing show in Anaheim, Calif.

Indspec says its diols improve PU stability
Indspec Chemical Corp. said resorcinol-based diols it has developed improve thermal stability and toughness in polyurethanes compared with butane diol.
The Pittsburgh firm said urethanes made with its products maintain a high level of performance after exposure to more than 210° F. Diphenylmethane diisocyanate urethanes formulated with Indspec's resorcinolic diols are suited to automotive under-the-hood parts, conveyor belts and load-bearing wheels.
The diols contribute to crystalline hard segments of urethanes to improve performance, Indspec found in a research program.
