Standard presses now convertible to MuCell. (Keeping up with Injection Molding).Trexel Inc., Woburn, Mass., has introduced a retrofittable injection unit that allows an existing injection machine to be converted at relatively low cost to microcellular foam molding by Trexel's MuCell process. Up to now, machines had to be converted off-site by lengthening lengthening (lengkˑ·the·ning), n the use of various massage or muscle energy techniques to relax and stretch muscle and connective tissue. their bases to accommodate a longer (28:1) screw and barrel. Also, machine controls needed to be modified or replaced to incorporate MuCell functions. Trexel is now offering a MuCell Modular Upgrade (MMU (Memory Management Unit) The part of the computer that governs memory access. Either part of the CPU chip or housed on separate chips, the MMU controls memory partitions and virtual memory. See memory and virtual memory. MMU - Memory Management Unit ) kit as a "drop-in" retrofit ret·ro·fit v. ret·ro·fit·ted or ret·ro·fit, ret·ro·fit·ting, ret·ro·fits v.tr. 1. To provide (a jet, automobile, computer, or factory, for example) with parts, devices, or equipment not in for most existing machines. "Until now, retrofitting for MuCell molding has been inhibited by high cost and long machine downtime The time during which a computer is not functioning due to hardware, operating system or application program failure. ," states Trexel v.p. Dan Szczurko. The new MMU consists of an injection unit with redesigned 22:1 screw that can be substituted directly for the existing injection unit. The MMU also includes a modified version of Trexel's gas-control unit (Series II SCF SCF Service Canadien des Forêts (Canadian Forest Service) SCF Stem Cell Factor SCF Scientific Committee on Food (European Commission) SCF Service Canadien de la Faune ) that now operates independent of the machine controller. As a result, an MMU can be installed in a week at the molder's plant without modifying the machine platform or controls. MMUs cost upwards of $30,000, depending on screw size.
