Steel sheath protects Burling controllers Burling Instruments Inc. of Chatham, N.J., said its 2300 Series of solid-state temperature controllers are rugged, and offered with either NEMA-4 or explosion-proof enclosures.
In the locally mounted version, the thermocouple sensor is protected by a rigid, stainless-steel sheath. A flexible cable protects the sensor for remote mounting.

Winder maintains continuous torque
Paragon Technology Inc. of Akron, Ohio, has developed a winder for putting a continuous strip of plastic or rubber onto reels or coils.
The company says its nonlinear slide winding system eliminates voids and overlaps, and maintains a constant torque.
A separate, servo-driven motor moves the sliding device.

Athena controller offers dual-voltage
Athena Controls Inc. said its Series SY hot- runner temperature controller can work on two voltages — the standard 240 volts (alternating current) or 24 volts.
Some imported heaters use 24 volts, according to Athena, of Plymouth Meeting, Va.
A safety interlock makes it impossible to plug the 24-volt module into the slot for the 240- volt module.
The low-voltage option has the same features as the 240-volt version, including dual digital displays, advanced diagnostics and Athena's CompuStep feature for gradual phase warm-up. It also offers the CompuCycle feature, which improves response time and extends heater life.

Pelletizer designed for quick cleanings
Gala Industries Inc. of Eagle Rock, Va., designed its MB500 pelletizer specifically for color compounds and masterbatches. It can run 1,100 pounds of material an hour.
Gala is touting its new tempered-water system, which allows quick cleaning between batch runs. The tank lid opens, giving unobstructed access to the process water tank, which also has a sloped bottom for complete drainage. Also, the centrifugal pellet dryer is mounted on a manually operated lift arm so it can be removed easily, opening up access to the dryer screen, rotor and base section.
The pelletizer also has a touch-screen control and Gala's spring loaded cutter.

Novapax blow molders debut in N. America
A German blow molding machinery maker, Novapax Kunststofftechnik GmbH, is entering the North American market with a line of four-station injection blow molding machines.
Novapax said the machines, in clamping forces from 44-138 tons, can process PET, polypropylene and containers with thick walls.
According to the company, cycle times are faster than three-station blow molders, especially when the fourth station is used for the heat transfer process. Another feature that trims cycle time: Clamp cylinders controlled by proportional hydraulic valves to reduce the mold opening distance for small containers.
The machines have mold stack heights of 8 inches and 10 inches.
Novapax, of Leers, Germany, has priced the blow molders starting at $195,555.
The company's U.S. office is in Hammonton, N.J.

Zumbach X-ray unit boasts high accuracy
Zumbach Electronics Corp.'s Rayex Model 220P does on-line measurement of foam-core pipe with solid inner and outer walls, using low-intensity X-rays.
The device checks wall thickness, diameter, ovality and foam expansion rate.
Zumbach, of Mount Kisco, N.Y., said the Rayex system is designed to check products that cannot be measured by ultrasonic systems because of energy absorption.
The complete pipe cross-section, with all related data, is displayed on a color monitor. When a parameter goes out of tolerance, the display changes to bright red.
