Euromold To Feature EOS Laser-Sintering Systems

EOS will display its EOSINT P 395 and EOSINT P 760 plastic laser-sintering systems at this year's Euromold exhibition, to be held 2-5 December 2009. The modular nature of both systems allows for a high degree of flexibility. Individual modules can be excluded at first, reducing the initial investment, but can be added at any future time. Both systems also offer the option for upgrading, with substantially improved process modules to support the strategy of part property management. A re-engineered laser-optics module (surface module) improves the quality of vertical surfaces into regions that until now have been exclusive to Formiga parts.

The Eosint P 760 can be optionally equipped with OLPC, which monitors and controls the laser's power during the building process, ensuring a more constant power than was previously possible. The Eosint P 760 is available with Flashrecoating, a new x-axis control that increases productivity by accelerating the re-coating speed up to 400mm/s. With the appropriate packing density, build-up rates of up to 700cm/h are realistically achievable. The recoating unit in the Eosint P395 has also been improved.

The introduction of PPPs has led to the integration into the Eosint P 395 of EOS's successful blade-cartridge concept, which was introduced in the Eosint P 730 in 2007, making it simple to carry out adjustments and change the layer thickness. A new version of the Eostate software, which monitors and reports on laser-sintering production, will also be presented at Euromold. Eostate 1.2, with a new array of report and analysis options, is EOS's answer to the increase in demand for transparency and continuous quality assurance in series-production processes. As such, the software complements the PPPs perfectly and is available for all plastic and metal systems.

The standardised reuse of powder materials is a prerequisite for continuously sustaining high quality in ongoing production. To fulfil this, EOS has adapted the successful concepts of other product lines to develop an integrated process chain management (IPCM) for Eosint M systems. The most important step here in quality assurance is the fast sieving of powder under defined conditions before its reuse. The IPCM ensures vibratory sieving under defined conditions and mesh sizes adapted and optimised for individual powders.

Powder preparation outside the machine, for example via powder homogenisation, enables the highest quality as well as maximum productivity and flexibility. Further increases in productivity and user-friendliness can be achieved with EOS's IPCM modules for fast powder conveying and machine refilling. The IPCM product range includes multipurpose lifting trolleys for transporting powder containers, as well as for building platforms and clamping systems.

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.
