SPR mixer permits cooler temperatures Scientific Process & Research Inc. is giving the plastics industry a Left Hook — a new mixing screw for blow molding, that is.
Working with a blow molding company, SPR, of Somerset, N.J., replaced the Maddock-style mixers on the its existing barrier screws with a series of "L"-shaped elements. The new screw elements force the material to separate and mix.
SPR said the Left Hook style immediately boosted the blow molder's output by 5-7 percent, with operating temperatures 5 degrees cooler. The new design also gave a wider processing window.
SPR said the Left Hook Mixer also works in extrusion and injection molding.

Industrial Extrusion offers extrusion belt
A new mandrel-made belt from Industrial Extrusion Belting is designed for pulling large profile extrusions, such as vinyl windows.
The company is expanding by 5,200 square feet to produce the larger belts, up to 300 inches long with no splices.
Industrial Extrusion Belting will show its big belts at NPE 2000.

Stapla welding unit designed for easy use
An ultrasonic plastic welding machine from Stapla Ultrasonics Corp. borrows technology originally developed for high-precision metal welding.
Stapla, of Wilmington, Mass., touts the machine's one-button operation. A simple-to-use controller has a key switch on the output panel for picking the operation level, an indexed exchange system for the welding tools and self-calibrating force measurements.

Balluff position sensor gives molders choices
Balluff Inc. of Florence, Ky., said its Micropulse noncontact linear position sensor is a drop-in replacement for linear potentiometers on plastics machinery.
The unit can be used to control clamp stroke, injection, die height, ejection and other positioning functions.
Specific applications include a maker of blow molding machines that uses Micropulse for platen position on its dual-servo-valve actuation system. One injection molding company used the Micropulse to replace a transducer that was misreading because of electrical noise from a nearby robot.
Balluff will show the sensor at NPE 2000.

Mold-Master develops interactive software
Mold-Masters Ltd. is pitching a F.I.T.
That stands for a fully interactive training program for its Temp-Master control screen. F.I.T. allows users to experience "real world" molding conditions and understand the role of the temperature controller, said the Georgetown, Ontario, company.
The software comes standard on all new Temp-Master controllers. F.I.T. also can be accessed on the company's Web site, www.moldmasters.com.

Rotex unit analyzes data automatically
Cincinnati-based Rotex Inc. said its particle size analyzer, the Gradex 2000, automates the sieve analysis of dry, granular material.
Samples are analyzed and data recorded automatically in a Microsoft Access database, eliminating the need for operators to weigh, calculate and record data.
Samples can be analyzed individually, or up to seven samples can be run continuously in an automatic mode. Each sample is fed into a stack of test sieves. Gradex 2000 automatically classifies and weighs the results, stores the information and empties and cleans sieves for the next analysis.

MicroCompounders mimic larger units
Daca Instruments said the new model of its MicroCompounder can be controlled using a desktop computer.
The new controller is compatible with earlier MicroCompounders, according to the company in Goleta, Calif. The software controls the temperature and speed of compounding to study the impact of processing temperature on the viscosity of the polymer.
The tiny twin-screw extruder, which has conical screws, is designed to process just 0.15 ounces of material. The unit mimics the behavior of large twin-screw compounders.
