DUBLIN, Ohio -- Infusion molding is rapidly becoming a leading technology for many industries that use composite materials in their manufacturing process. Ashland Composite Polymers, a business group of Ashland Specialty Chemical, a division of Ashland Inc. (NYSE: ASH), recognizes the future importance of infusion molding and has added a dedicated laboratory to its research and development capabilities.
"We can now more readily adjust to and support our customers' needs," said Andy Beer, global marine marketing manager, Ashland Specialty Chemical. "Although boat-building primarily is open contact molding, using either a hand lay-up or spray-up method, many in the boating industry are switching to, or investigating a move to, infusion molding. It is quickly becoming the method of choice for reduced styrene levels during construction. Its advantages also include improved physical properties, consistency and even cost reduction depending on part size."
The new laboratory allows Ashland scientists to better assess changes in resin formulation, gauge flow, compatibility of catalysts, and temperature. The laboratory capabilities also provide better opportunities for product innovation and discovery.
Infusion molding uses an air-tight, sealed sheet that surrounds a mold. It is then subjected to vacuum pressure to draw the composite resin through layers of fiberglass. The fiberglass can be used alone, or it can overlay other materials such as balsa wood or foam core. "This process is being implemented in a number of applications so it is very important that we continue to expand our exploration of this technology," said Beer.
