The Science Of Precision Coatings

Plastic Injection Molding

Key Benefits:

  • Wear resistance,  especially glass filled resins
  • Release, lubricity
  • Flow rate, lubricity
  • Improved cycle times, lubricity
  • Thin, even deposit for conformance to geometry without re-machining
  • Can be re-applied many times over, minimizing cost of new molds
  • Chemical attack resistance, gassing
  • Low temp process will not affect part geometries
  • Uniform cooling, improved cycle times
  • Thermal conductivity, mirrors substrate, no hot/cold spots due to coating
  • Easy to clean media debris and residue from critical areas, lubricity and release
  • Results in reduced product defects, reduced downtime, scrap, and labor hours, increased production due to increase cycle times and reduced maintenance/setup and tear down, improved mold performance and reliability, higher margins on production runs, faster break even on mold manufacturing costs

Through precise, engineered deposits, Armoloy TDC®, XADC®, and Nyflon 25® add incredible value to plastic injection molding applications, as well as those in the areas of extrusion and thermoforming.

Particularly in the case of glass-filled resins, the Armoloy coatings improve cycle time and wear life by imparting a harder, more lubricious surface to molding components. Unlike many other surface treatments, the Armoloy coatings can be removed and reapplied, as wear life and maintenance schedules dictate, with no damage incurred by the base metal. Textured surfaces will retain their integrity after the Armoloy coating process.  Considered a cold process, the Armoloy system prevents distortion, annealing, and dimensional changes from occurring in the base metal.

Increased material flow, reduced maintenance time, cleaner molds, and release of the formed part from the molding tool are additional advantages the Armoloy coatings offer to the plastics forming industry.  In a current application for a high end office furniture manufacturer, The XADC® coating was applied for improved wear resistance, flow rate, and release.  Time between maintenance cycles of the mold, which included expensive tear down and loss of production, increased from, on average, 12,000 shots to over 100,000 shots.

In addition to standard molding steels such as A-2, S-7, and H-13, the Armoloy coatings can also be applied to stainless steel, copper, beryllium, and bronze alloys such as Ampcoloy.

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

The Armoloy family of coatings are specifically designed to keep machinery and equipment running longer. For increased wear life, reduced friction, protection from corrosion and galling, and many other benefits, Armoloy of Illinois provides a full range of metallic surface coatings to the manufacturing community. High precision is our specialty.

Armoloy provides industry-leading protective metallic coatings that benefit various industries, including food processing/packaging, oil/gas extraction, Aerospace, medical, and nuclear industries, to name a few. Metal surface treatments tailored to these applications must withstand extremely harsh conditions and provide added durability capable of extending the life of components and systems. Our experienced staff can help engineer the right metal finishing solution to your application.

Our proprietary metal surface treatments are fully compliant with the industry's most rigorous requirements and certifications. At less than 170ᵒF, the Armoloy metal finish process is considered a "cold process" that will not distort or anneal coated parts. The Armoloy coatings form a hard protective metallic surface with an absolute bond to the base metal that will not affect part tolerances or balance. This thin, precision coating will improve surface hardness and lubricity while dramatically increasing your coated parts' wear life. Our stringent quality requirements and onsite product testing will ensure your parts meet strict industry standards.

Armoloy offers a variety of coating solutions engineered to solve your coating needs. The Armoloy TDC/XADC coating will not flake, chip or peel from your base material ensuring a safe coating process that is food and medical application safe. Your maintenance and machinery expenses will lessen thanks to the coating's increased wear resistance leading to decreased downtime and replacement costs. Don't settle for traditional metallic plating shortcomings when you can have the Armoloy family of coatings protecting your valuable automated systems and components.
