Efficient Cleanroom Manufacturing
At the Medtec trade show (February 26 to 28 in Stuttgart, Germany), Dr. Boy GmbH & Co. KG, Neustadt-Fernthal, Germany, is demonstrating the sprueless production of closures for insulin pens with a 16-cavity mold on a Boy 35E with stainless-steel fittings. This machine, designed for cleanroom class ISO 7, features not only an antistatic paint finish, but also an ionization box for filtering the air in the mold region. “The less space that must be isolated from the ambient air, the lower are the technical outlay and costs,” explains Michael Kleinebrahm, head of applications technology at Boy. “Since the hydraulic clamping cylinder of the two-platen clamping unit is mounted outside the cantilevered mold space, this design offers considerable advantages for parts production under cleanroom conditions. With the Boy 35E, the entire cleanroom consist of the clamping-unit mold space, the ionization box is integrated on the safety cover to save space. This minimizes the investment and operating costs.
The efficient drive concept of the Boy 35E with servo motor pump drive loses very little waste heat. In conjunction with the laminar flow hoods and stainless steel fittings, it represents an optimum clean-room machine configuration. In such cases, Boy works together as a system supplier with specialized partners, such as Max Petek Reinraumtechnik. The medical applications realized on Boy automatic injection molding machines have so far comprised various equipment components and sensor parts with integrally molded cables, as well as catheters with complex actuators, with LSR overmolded cannulas, resorbable implants and palliative care products.
