Reel-to-Reel Molding

Also known as continuous molding, Ironwood Plastics has been in this business since 1996.

Benefits of reel-to-reel molding:

  1. Finished product is shipped back to the customer on a reel. Parts are oriented for assembly, eliminating the need for bowl feeders.
  2. Because inserts are shipped to IWP on a reel, there is less chance for damaged inserts before molding.
  3. Inserts loaded mechanically- less labor.
  4. Components can also be routed after molding to a stamping die for final bending or singulating operations to produce the final product.
