Dynisco Instruments sensor goes digital
Dynisco Instruments is now offering digital CANopen-Bus protocol technology in melt and industrial pressure sensors.
The low signal of the pressure-sensing element is converted from analog to digital, then goes through a microprocessor. The scanning and conversion rate is only 20 milliseconds.
The Can-Bus protocol links the sensors to host systems. Features include automated transducer calibration, limit-setting and pressure supervision, both on the processing machine or centrally.
Dynisco Instruments is a unit of Dynisco LLC of Franklin, Mass.

Priamus Fill system balances hot runners
Priamus System Technologies AG of Schaffhausen, Switzerland, is selling its Priamus Fill system for balancing hot runners, where identical set values of the nozzle temperatures lead to different filling rates of each mold cavity.
Usually, the solution is to set nozzle temperatures with short shots until all the cavities are filled simultaneously. But often, the system gets out of balance again, Priamus said.
Priamus Fill permanently adjusts the set values of the hot-runner nozzles, automatically balacing the fill phase of the single cavities. The device compares mold temperatures for each cavity and controls the nozzle temperature.

Raytek Corp. presents laser-imaging systems
Raytek Corp. has launched two laser-imaging systems for film extrusion.
The EC100 monitors the temperature of film extrusion, extrusion coating and lamination. The ES100, meanwhile, does early detection of die bolt heater problems or plugged dies, by subdividing a thermal imaging into a selected number of sectors that correspond to a die bolt.
Both systems feature Raytek's MP50 Process Imager. After the imager is installed, the entire system usually can begin operating in less than one hour, according to the company in Santa Cruz, Calif.
Prices for the ES100 begin at about $13,750. The EC100 system, which also includes laser aiming, is priced at $16,000.

Routsis CD-ROM up on the latest technology
A new CD-ROM training program from A. Routsis Associates Inc. covers basic maintenance of injection molding machines, as well as the latest technology such as laser leveling, ultrasonic tie-bar stretch measuring and portable machine-process monitoring devices.
Routsis, of Dracut, Mass., said the program is designed for production mechanics, maintenance personnel and plant managers.
Routsis also offers ``Mold Design and Mold Making,'' for tool designers, mold makers, engineers, part designers, instructors and anyone involved in buying tools.
The series covers various types of injection molds, the machining methods used and mold components. It includes a sample mold specification guide for reference.

Wallmaster allows precise extrusion
Zumbach Electronics Corp. of Mount Kisco, N.Y., is marketing its Wallmaster extrusion control system for precise, very small extruded products such as medical tubing and catheters.
The controller automatically controls diameters down to 0.010 inch and wall thickness as thin as 0.0004 inch.
Wallmaster can measure parts with as many as five layers, depending on the tubing construction. The system allows the processor to do real-time trending displays, generate charts for statistical process control and statistical quality control, and network a plant. A touch screen is available as an option.

Epcon Gas debuts pressure controller
Epcon Gas Systems Inc. of Rochester Hills, Mich., has introduced a pressure controller and a shut-off nozzle for gas-assisted injection molding.
The Micro-controller, which comes in two- and four-valve pressure controller models (MC2 and MC4), features a 14-inch color touch screen, independent pressure control to four injection presses, six pressure zones with ramping ability and pressure gauges with quick shut-offs.
The shut-off nozzle shuttles forward during injection forward and snaps shut at gas injection. The insert element does not require any hydraulic or pneumatic mechanical action.

Sonics & Materials offers small welder
Sonics & Materials Inc. of Newtown, Conn., offers a hand-held welder, Model H-540, for small plastic welding jobs.
The low-amplitude welder reduces the chances of marking the surface, when heat staking, inserting and spot welding. It also is suited for manual, low-volume operations and for assembling parts with hard-to-reach weld areas.
H-540 also eliminates the need for tuning the system when changing horns, thanks to a newly designed power supply.
