Windsor develops retrofit injection unit
PlugXPress is the name for an inexpensive retrofit two-component injection unit from Windsor Kunststofftechnologie GmbH, a unit of Italy's Cannon Group.
Windsor of Hanau, Germany, developed the product around a series of four standard plug-and-play injection units and machine interface kits. Each injection unit has its own hydraulic power unit with an integrated electronic control. The design avoids the need to break into the injection press's hydraulic or control system.
Another advantage is the PlugXPress injection unit can be moved between presses, even between machines with a vertical clamp and horizontal clamp.
The four models have screw diameters of 24, 34, 42 and 50 millimeters and deliver corresponding maximum shot weights of 1.61 ounces, 3.57 ounces, 6.82 ounces and 11.58 ounces.

BKG acquires rights to Eastman patent
The BKG Underwater Pelletizing Systems Division of Kreyenborg Industries has acquired international patent rights from Eastman Chemical Co. for processing sticky or tacky polymers using underwater pelletizers.
Those types of polymers tend to stick together just after being cut or during storage.
The patented process is covered under U.S. patent No. 5,041,251. The process eliminates normal surface tack by applying a compatible, nonsticky material during the water-cooling period. Then, after the pellets are separated from the cooling fluid, they get coated a second time. The result is the processor can use a higher-temperature cooling fluid and store pellets at higher temperatures, saving money and delivering higher-quality pellets, said BKG Kreyenborg of Norcross, Ga.
BKG Kreyenborg is sublicensing the patent to any processor that will use its machines, or for royalty payments if the process is used with other equipment.The worldwide patent rights were transferred to BKG/Kreyenborg in December, and the company announced the news earlier this year.

Leistritz introduces barrel cooling option
A newly designed twin-screw barrel section promotes a big increase in heat transfer for segmented twin-screw extruders from American Leistritz Extruder Corp. of Somerville, N.J.
The company points out that increased cooling is especially desirable with high screw speeds being used today.
The length of each barrel is four times its diameter, so a 100-millimeter twin screw uses a 400-mm-long barrel. Internal cooling bores are arranged close to the barrels' figure-eight pattern and the melt stream.
The number of cooling bores for each barrel has been increased to facilitate heat transfer for each section.
Leistritz has boosted the rate of coolant to the barrels to match the improved heat removal. Flow rates can be individually regulated via needle valves to handle different temperature set points along the length of the barrel.

Chen Hsong unveils gas-assist machine
Chen Hsong Machinery Co. Ltd. launched its all-electric injection molding machine at HK Plas 2001, a trade show in Hong Kong.
The Eco Series of all-electric presses uses 35-60 percent less energy than a hydraulic machine, Chen Hsong said. Also, plasticizing, clamping and ejecting can be performed simultaneously.
Another new press, the Jetmaster C Series, has a five-point toggle clamp for stability and a shorter stroke, with five stages of injection speed and seven stages of injection pressure, making the presses suitable for high-precision molding. Although not all-electric, JMC presses also boast energy savings of 30 percent from a hydraulic pump that automatically adjusts output.
At HK Plas, the Hong Kong company also showed the Swift SR-1200 side-entry robot for small-tonnage injection presses of clamping forces from 128-268 tons. Chen Hsong offers the Swift with either pneumatic or servo-electric power.

Bry-Air announces FDL dryer, controller
Bry-Air Systems has introduced an FDL series dryer and controller.
The FDL rotor-based resin dryer can handle 900-7,000 pounds of material an hour. Bry-Air claims the desiccant wheel, rotor-type design is better than designs with loose granular desiccant because a greater velocity of air can be passed through the desiccant with less heat carryover. That results in a smaller and lighter unit and virtually eliminates dew-point spiking, according to the company in Sunbury, Ohio.
The Smart-Dry controller has several functions, including a seven-day timer, dew point monitor, process and regeneration temperatures, return air temperatures, process and generation blowers, and alarm functions. A feature called ``true dew point controlling'' lets operators set and maintain their desired dew point.
