Plastic injection

Armoloy TDC® coatings provide significant value to plastic injection molding applications as well as extrusion and thermoforming processes through precise technical procedures.

In particular, when it comes to materials containing glass fibers, Armoloy coatings enhance cycle time and lifespan by providing the molded parts with a harder and more lubricious surface. Unlike many other surface treatments, Armoloy coatings can be removed and reapplied based on wear life and maintenance schedules without damaging the base metal. Textured surfaces maintain their integrity after the Armoloy coating process. The Armoloy system is considered a cold process, preventing warping and changes in hardness of the base metal.

Additional benefits that Armoloy coatings offer to the plastic forming industry include improved material flow, reduced maintenance time, cleaner molds, and simplified part release from the mold tool.

Armoloy coatings can be applied not only to cold work tool steel and hot work tool steel but also to stainless steel, copper, beryllium, and bronze alloys such as Ampcoloy.

Typical applications

Typical applications include core and cavity blocks, lifters, sleeves, ejector pins, bushings, rotating cores, and inserts.

key benefits

The key benefits of Armoloy coatings are:

  • Wear resistance, especially with glass-filled resins
  • Release and lubricity
  • Improved flow and lubricity
  • Enhanced cycle times and lubricity
  • Thin, uniform deposition to conform to geometry without post-processing
  • Can be applied multiple times, minimizing the cost of new molds
  • Resistance to chemical attack and outgassing
  • Low-temperature processes do not affect part geometries
  • Uniform cooling, improved cycle times
  • Easy removal of media residues and residues in critical areas, better lubricity, and easier part release
  • Results in fewer product defects, reduced downtime, scrap, and labor hours, increased production through extended cycle times and less maintenance/setup and teardown, improved mold performance and reliability, higher profit margins on production runs, and faster return on mold manufacturing costs.
