Dental equipment molder UltraTek will take over an additional 40,000 square feet for automated assembly operations at its South Jordan, Utah, plant.
UltraTek is expanding to accommodate growth at its parent company, Ultradent Products Inc. in South Jordan. Ultradent is growing at 20-24 percent a year, said Richard Rachal, vice president and plant manager for UltraTek.
The company will not be buying new machines to meet that growth but spent about $900,000 last year on high-cavity tooling, and plans similar spending in the next 18 months, he said.
The additional 40,000 square feet will give UltraTek a total of 70,000 square feet. The company has 17 presses, and molds both for Ultradent and other customers.
PTG copolymer blend OK for TP processes
Medical biomaterials and implant manufacturer Polymer Technology Group has introduced what it says is the first silicone-urethane copolymer that easily can be used in traditional thermoplastic processes, such as injection molding.
PTG of Berkeley, Calif., has used the material in its own products for seven years, but first introduced it publicly in August, said President Robert Ward. The material combines the strength and processing advantages of urethanes with the biostability and biocompatibility of silicones, he said.
The material can be used as pellets for molding, solutions for dipping, coatings and two-component castings. The material could be used as a silicone-rubber replacement, Ward said.
Advanced develops microporous process
Advanced Polymers Inc. has developed a microporous membrane technology for medical balloons and filtration tubing.
The process only works on biaxially-oriented PET tubes and balloons, but can make products with between 100,000 and 50 million holes per square centimeter, said Mark Saab, president of Advanced Polymers.
The process has applications in drug delivery balloons where very expensive or very toxic drugs must be delivered in small amounts to precise locations, he said. Its applications range from better delivery of existing anti-coagulant drugs to new gene therapy medication, he said.
The holes are made by irradiating the material and then etching it, he said. The technology was developed by eMed, a Minneapolis start-up medical manufacturer, and the etching is done by an unidentified Switzerland-based firm.
EMed is working with pharmaceutical companies to develop "the magic drug" for the technology, Saab said.
