Insulating Panels for Energy Conservation and Efficiency
For decades, the OMS Group has been at the forefront of developing highly personalized technical solutions and turnkey systems for the discontinuous and continuous production of flexible, metal and rigid sandwich insulating panels of PUR/PIR foam, phenolic resin, preformed core materials such as EPS and mineral fiber lamellas.
The list of OMS installed systems includes plants for the continuous production of flexible substrate panels for roofing, cavity wall insulation and ducts for air conditioning systems; panels faced with rigid gypsum, cement or wood products for residential construction elements, roof panels, thermo-ventilated roof systems, etc.; and metal faced composites for cold storage, industrial roof and wall construction applications.
Demand for insulation with improved thermal and fire properties fed tremendous growth in the number of continuous panel plants over the last few years. This year, in recognition of this ever-growing demand and the company's 40th anniversary, OMS Group launched OMS Automation, an engineering division dedicated to developing material handling equipment for panel production.
Rising energy costs and government incentives focused on energy conservation likely will keep demand high in the future. Some early entrants into panel manufacturing also are looking for ways to reduce costs with newer technology.
"Some panel manufacturers and many commercial refrigeration manufacturers have been using 'froth' foam, which doesn't require the use of high- or low-pressure metering machinery," Clark said. "Their initial equipment costs were low, but inaccurate process control resulted in poor foam quality and high chemical costs because of waste. So now these processors are starting to look at high- pressure metering systems and two-component traditional foam."
During NPE2009, OMS will display its Y2K 10 straight, high-pressure mixing head, which is ideal for continuous and discontinuous panel production. The compact Y2K 10 head is designed to accurately control chemical temperature, pressure and mixing for superior chemical usage and foam density control. The head instantly dispenses mixed chemicals as soon as a pour cycle is actuated and instantly stops the pour cycle, eliminating chemical waste.
Elastomers: One of the Fastest Growing Plastics Industry Sectors
Elastomers are used to make such a wide range of products, from hard in-line skate wheels to rubbery gaskets and spongy foams of running shoes, that this broad family of polymers has become one of the fastest growing sectors in the plastics industry.
Because their physical properties often rely on complete and precise control of the temperature, pressure and amount of chemical components that are mixed, engineering grade and high-temperature elastomers required specialized machinery to process them repeatedly and reliabily.
OMS Group manufactures a range of standard medium- and high-temperature machines, as well as purpose-built material handling equipment, for making products and coatings from elastomers. OMS recently designed and installed a low-pressure metering unit that will be used to apply an elastomeric glass syntactic polyurethane-based material to pipe destined for a deepwater ocean oil field. OMS also has developed a fully integrated micro-metering plant for gasket production using thixotropic materials.
"At NPE we will display a low-pressure mix head that is perfect for gasket, filter and small parts produced from elastomers," Clark said.
The C2 Micro Dosing Mix Head features:
·Output range of 2 to 20 gm/sec.
·An internal pneumatic piston that actuates both chemical pistons together to eliminate"lead/lag" problems.
·Chemical reciculation through the jacketed mix head for optimum temperature control.
·Fixed orifices to control chemical pressure.
