Dongshin sells MuCell press to Samsung unit
South Korea-based Dongshin Hydraulics Co. Ltd. reports it sold the largest injection press for running the MuCell microcellular process - a machine with 1,760 tons of clamping force - to the Home Appliance Division of Samsung Electronics Co. Ltd.
Samsung is using the press to mold washing machine agitators.
Dongshin licenses the MuCell process from Trexell Inc., based in Woburn, Mass. MuCell allows molders to make large parts that are thinner, ligher, flatter and more dimensionally stable, according to Donshin. Large, thin-wall parts can be molded with less risk of warpage and fewer sink marks.
Typical applications include automotive, packaging and appliances.
Dongshin is headquartered in Pusan, South Korea. Its U.S. subsidiary, Dima Inc., is based in Santa Fe Springs, Calif.

Iron maker acquires Krauss-Maffei press
Rowenta, which makes steam irons in Erbach, Germany, has purchased a two-component injection press with a swivel-platen from Krauss-Maffei Kunststofftechnik GmbH.
The KM650-1900/1900WP press uses a swivel platen that holds a four-cavity, two-component mold. The platen is mounted on lateral guides, ensuring a high degree of platen parallelism.
Krauss-Maffei of Munich, Germany, said a major benefit of swivel-platen technology is wide-open access for automation. At Rowenta, parts are removed from the side by an articulating-arm robot, which is mounted on a mobile unit that then delivers the parts to downstream processing operations.
After the sprue is removed, the system does a quality check to make sure the water channel is formed correctly on the iron. Then, small metal balls are automatically inserted, snapped into position and checked to make sure they seat properly to prevent any leaks.
The swivel platen setup allows Rowenta to use a small amount of space for its automated work cell.
Krauss-Maffei's U.S. operation, Krauss-Maffei Corp., is in Florence, Ky.

Milacron seminars set for fall, winter
Milacron Inc. will hold a series of three-day Predictive Maintenance Technical Training Seminars for injection molding machines this winter.
The courses are designed for maintenance/production supervisors and other managers involved in injection molding machine scheduling, maintenance and operation. They cover every facet of preventive maintenance, from identifying causes of wear and failure to thermography, ultrasound and vibration, oil and wear particle analysis. Hands-on training will be conducted on presses from Cincinnati Milacron and Ferromatik Milacron Europe.
CFC-Solar Inc., an industrial training company, designed the courses and will handle the instruction. The seminars were developed to support Milacron's Contract Services Rebuild and Retrofit business.
Bob Strickley, marketing manager for the company's Cincinnati Milacron injection presses, said machines have to be ready to mold once an order hits the factory floor. ``Our customers have requested formalized training on predictive maintenance and other advanced maintenance techniques,'' he said.
The first seminar was held in September. The next is scheduled for Nov. 30-Dec. 2. It will be held at the Adams County Business Training Center, in Winchester, Ohio, a branch of Southern State Community College.
