Robotic transporters are key when you want to automate welding of extremely large, heavy parts. The maximum work envelope radius of an extended-reach robot is about 3-meters (9.84’). If the parts you are welding require more reach than that, you need to find ways to move the robot to the part to provide optimal torch access to the welds. A variety of robot transporters are available, and each type lends itself to a particular type of work flow. How do you decide whether your application is best-suited for a linear floor- or wall-mounted track, linear overhead gantry or radial transport beam solution?

Researchers at Northwestern University and Princeton University have created a new kind of polymer that, because of its extraordinary thermal and mechanical properties, could be used in everything from airplanes to solar cells.
The polymer, a nanocomposite that incorporates functionalized, exfoliated graphene sheets, even conducts electricity, and researchers hope to use that property to eventually create thermally stable, optically transparent conducting polymers.

Mykroy/Mycalex (MM) Glass bonded mica material is a trade name of CRYSTEX Composites LLC. Since 1921, Mykroy/Mycalex composite remains the most versatile and efficient electrical and thermal-insulating materials refined to meet the exacting demands of technical markets. MM material is the only mineral, fully inorganic material, to bridge the performance gap between organic plastics and mineral ceramics. Mykroy/Mycalex material is a union, under simultaneous pressure and heat, of finely powdered electrical quality glass and precisely defined and classified mica. The resulting stone-like, dense ceramic, inherits all the insulating advantages of both constituents. It can be easily machined to close tolerances or transfer molded into intricate shapes with or without metal inserts. MM material is impervious to moisture, and does not outgas under high temperature or in vacuum environments. It manifests exceptional dimensional stability even at high temperature. It does not burn or carbonize and has an unlimited shelf life.
Unique in the United States, CRYSTEX Composites LLC has produced its own Synthetic Mica since 1955.
PREMATECH ADVANCED CERAMICS combines the highest level of service with an extensive knowledge of ceramic machining. A truly scientific approach is applied to the process to maintain consistency, reliability, and cost-effectiveness.

Background
With an annual production of approximately 10 million products a year and manufacturing operations in 12 countries Grundfos is one of the most recognised and respected pump manufacturers in the world. Dedicated to making its products as reliable and durable as possible, Grundfos works with partners, education institutions and suppliers to research and develop the best pump technology for its products. One of the longest relationships of this kind is with Morgan Advanced Ceramics, which supplies the manufacturer with bearings, shafts and washers for its circulator pumps.
Circulator pumps are used in central and district heating systems and domestic service systems. They need to be able to run quietly and consistently for long operational periods - often up to 5,000 hours a year. As part of its on-going work to improve its products, Grundfos realised that the traditional steel-shaft carbon bearings used in the pump were having a direct impact on the pump’s longevity and noise.

Boron nitride is a synthetic material, which although discovered in the early 19th century was not developed as a commercial material until the latter half of the 20th century. Boron and nitrogen are neighbours of carbon in the periodic table - in combination boron and nitrogen have the same number of outer shell electrons - the atomic radii of boron and nitrogen are similar to that of carbon. It is not surprising therefore that boron nitride and carbon exhibit similarity in their crystal structure.
In the same way that carbon exists as graphite and diamond, boron nitride can be synthesised in hexagonal and cubic forms.
Ortech has a wide range of Technical Ceramics Materials to offer. Each one with its own unique characteristics designed to meet the requirements of many diverse applications. Some of the more widely used materials are described below.
Mems- Micro-Electro-Mechanical Systems from Universal Semiconductor, Inc. USI offers rugged, miniature, and high sensitivity MEMS process capability for manufacture of sensors, transducers, switches, mirrors, and many diverse special custom designed products that go into wide ranging applications from medical to aerospace.
The MEMS integrated sensor chip can be readily combined with a signal conditioning circuitry chip for amplification, offset compensation, linearity improvement, and temperature compensation. All parameters for amplification, offset compensation, linearity improvement, and temperature compensation are stored in an internal EEPROM. No additional components required, simplifies incorporation in to existing systems.
