IMS Co. unveiled two Ultraline separators for sorting of parts and runners. A drum-type separator uses adjustable slots in a rotating drum. It costs $3,500. The roller-type unit, which costs $2,500, uses counter-rotating rollers to sort parts.
IMS also offers a new mold sweep for automated part removal. It features a high-speed, rodless cylinder. Prices range from $2,195 to $2,395.
The Chagrin Falls, Ohio, supply firm also stocks Telar's Watt Watcher Granulator Controller, a device that runs the granulator only when there is material to be ground. A photoelectric eye instantly starts the motor when the granulator is fed. When the chamber empties, a vibration detector shuts down the motor again.
The controller costs $895 as a retrofit to any granulator, or $990 if installed in a new IMS granulator.
IMS also introduced Econo-Cube Silicone Mist to retain detail in parts molded by wax injection molding. The product is a lighter, lower-viscosity form of the silicone used in IMS' aerosol and Econo-Cube mold releases.

Despatch says ovens can ease part stress
Despatch Industries offers four new annealing ovens, the PA Series, said to reduce stresses in plastic parts through rapid hot-air annealing.
The computer-controlled ovens use a high-volume, ``vertical-up'' airflow.
According to the Minneapolis firm, the faster a plastic part can be heated to its softening temperature, the less physical aging and embrittlement will take place.
Typical cycle times for Lexan polycarbonate and Ultem polyetherimide are less than 10 minutes at 260§ F.

Davis-Standard has profile extrusion dies
Davis-Standard Division of Crompton & Knowles Corp. developed the L-I profile extrusion dies for profile configurations with up to eight lumens.
The stainless steel dies are equipped with breaker plates instead of conventional flat breaker plates to reduce resin degradation and boost melt quality. The melt thermocouple is immersed into the polymer stream. The die also has a flow-through mandrel.
Davis-Standard is based in Pawcatuck, Conn.

Die heads designed for pressure pipe
Processors can extrude up to 2,200 pounds an hour of high density polyethylene pipe on a series of die heads from Reifenhauser Inc. of Lawrence, Mass.
The die heads are designed for pressure pipe for carrying gas or water. A spiral mandrel reduces pressure loss in the die, for very high throughput at low melt temperatures, even when extruding smaller diameters, the firm said.
The die is designed to process all commercial polyolefins, plus ABS and recycled materials.

Delcam software aids complex spa design
Delcam International plc of Birmingham, England, said Crane Canada Inc. used its Duct software to design a new two-person bath.
Crane Canada, of Stratford, Ontario, did ergonomic research to create a model and tooling that would make a spa as comfortable as possible.
Use of the computer cut modeling time from 12-14 weeks to eight weeks, according to Delcam.

Hurricane loader helps remove fines
Hurricane Pneumatic Convey-ing Inc. has developed a loader, fitted with a lid section with filters, to handle fine powders such as resin.
Hurricane's patented double cyclone removes up to 99.95 percent of the fines before they reach the filter.
The loader is available as an option on all Hurricane conveyors with rates up to 50,000 pounds an hour.
The company is based in Brantford, Ontario.
