Linden adds to line of pumps it modifies
Linden Industries Inc., which makes polyurethane processing equipment in Cuyahoga Falls, Ohio, has expanded its Rexroth polyurethane pump repair services to include other pump brands: the RHL model from Rotary Power Pumps, Viking and MHR.
Linden also increased its range of pumps that provide magnetic coupling conversion, to include RHL and Rexroth pumps, low-pressure gear and feed pumps and day tank agitators.
Officials said Linden has seen a surge in demand for magnetic coupling conversions. The traditional seals used in pumps and agitators can deteriorate, leading to leakage of polyol and isocyanate, the company said. By converting to magnetic couplings, the inner magnet is isolated within the pump case.
To make the conversion, the pump drive shaft seal is replaced with two magnetic assemblies. The magnets create force that transfers torque from the motor to the driveshaft.

Software follows part through production
Los Angeles-based Algoryx Inc. is selling a system of algorithms that takes a part from pre-production tooling to production tooling.
The TRA computational software can cut much of the measurement and analysis costs on part dimensions. According to Steve Tuszynski, president and chief executive officer, the new algorithms are based on the fact that the relationships between effects for many processes are consistent and predictable, even with changes in the processing settings.
Tuszynski said plastic parts are the main focus of his company.

Firm offers portable hot-runner controller
Athena Controls Inc. of Plymouth Meeting, Pa., said its RMC/P single-zone, hot-runner controller is portable.
The ``go anywhere'' function offers a choice of three default modes for open thermocouple condition, built-in safety protection and the ability to accept a J or K thermocouple input. The CompuStep bake-out feature prevents moisture at start-up.

Cinpres marketing real-time part X-ray
Cinpres Gas Injection Inc. of Ann Arbor, Mich., announces a way for quality checkers to examine internal gas channels of a part made by gas-assisted injection molding - without cutting open the part.
The real-time, nondestructive test uses X-ray equipment. Cinpres offers the equipment in cooperation with the supplier, Alpetor Systems Inc. of Northbrook, Ill. The mobile machine takes up little floor space, so it can be located at research and development, production or assembly operations.
The Alpetor equipment is designed for day-to-day manufacturing environments. Up until now, film X-ray inspection has been possible, but it is expensive and requires special lead screen rooms.
Nonfilm X-raying also is expensive and is normally only available at universities or development laboratories.
Separately, Cinpres announced it is offering a way to simulate 3-D plastic flow into thick tubular products, such as handles. The technology was developed by the University of Wales at Swansea's Centre for Polymer Processing Simulation and Design.

Budzar touts line of chillers, controllers
Willoughby, Ohio-based Budzar Industries Inc. has developed a line of portable chillers and temperature module controllers - the Budzar World Alliance brand - that it said is priced 25 percent lower than similar equipment.
Features of the air-cooled and water-cooled chillers include a Copeland scroll compressor; a multistate centrifugal pump and a tank, both made of stainless steel; a NEMA 1 electrical enclosure; a hot-gas bypass; diagnostic lights on the panel and a control panel disconnect switch.
Features of the temperature control module include a 9-kilowatt heater with automatic air vent; temperature range from 50°-250° F; and a self-tuning solid-state controller.
