Injection Mold Coating

    We all know how technology has transformed the plastic molding industry.  The world economy has made it clear that advances in technology, as well as superior customer service and money-saving strategies, are critical to surviving in business.  Used and considered proactively, they really can make a difference.

New coating science

      The diverse world of molding materials now includes a multitude of glass-, mineral- and fiber-filled resins.  In turn, mold construction ranges from simplistic to complex and they are constructed from many types of metals.  There are many factors to consider, and it therefore becomes necessary to develop more wide-ranging forms of mold coatings that can facilitate optimum performance from the mold, whatever the application might be.

      For example, hard chrome, for all its benefits, does not tend to plate uniformly in detailed areas like ribs and bosses.  So, if you are molding highly intricate parts using glass-filled materials, it becomes necessary to use a coating that will preserve the mold’s integrity for trouble-free performance.  One solution is a nickel-cobalt composite coating.  The cobalt gives it its great abrasion resistance and the protection you need to keep running the mold with fewer maintenance checks.  It can also be an economical alternative to hard chrome.  Hard chrome requires construction of a conforming anode to coat the mold.  The more detail in the mold, the more time it takes to build the anode and the...
