New Features in CoMo Injection Process Monitoring System Make 100 % Injection Molding Quality Even Easier to Achieve

Kistler brings the quality-minded injection molder another substantial step closer to zero-defect production. The CoMo Injection Type 2869B… process monitoring system now offers many useful functions for faster production startups, even more efficient quality monitoring and – absolutely new – automatic quality prediction.

Automatic Online Prediction of Part Quality
The outstanding feature of the CoMo Injection system is the new module for automatic online prediction of part quality. Based on mold cavity pressure, contact pressure and process models, specific quality attributes of the part currently being produced are forecast. As early as the manufacturing stage, the CoMo Injection system with this new module predicts attributes such as the final dimensions of the molded part. This makes it possible to state during molding whether these dimensions will still be within tolerance when the part is actually used.

Manufacturers of injection molded parts can now take tolerance bands straight from the parts specification as criteria for the process monitoring system. Manufacturers of high-quality, hard-to-assemble or sensitive medical and other precision parts will profit most from this.

Monitoring Multicavity Molds and Automatic Mold Identification
When changing molds, the new automatic mold identification system simplifies and speeds up connection and setting up by automatically loading the mold and article data. It also makes it easier to detect connection mistakes.

Several CoMo Injection systems can now be cascaded to monitor multi-cavity molds with up to 64 cavities. Up to 33 digital outputs supply signals for part separation, alarms or switching. Setting up and visualization of all of the systems is performed by defining one as master then proceeding in the way familiar from a single system.

More Efficient Changeover with Mold Cavity Pressure
Retracing reference curves determined with parts of optimum quality guarantees rapid startup or resumption of production of high-grade products. This enables current production to be easily matched to the displayed reference curve. The reference curve can be read from the mold record or the database (CoMo DataCenter Type 2829B…), or obtained from cycles of "OK" parts of the current process.

New curve history functions enable scrolling through the last 3 000 cycles. Curve superimposition and a series of useful functions allow initial evaluation in the CoMo Injection system right at the injection molding machine.

The CoMo Injection system now has production control functions based on selectable criteria. This enables runs to be limited to a specified quantity of good parts, or stopped on the basis of certain criteria in the event of ongoing quality problems or process instabilities.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
