Thermoforming Chain

Diamond® Thermoforming chain is designed for thermoforming applications such as those used in creating polystyrene plates or medical blister packs. These chains feature precise, pointed linkplates combined with extended pins or straight attachments which make them optimal for conveying plastic film into thermoforming machinery.

Length matching is critical in thermoforming applications, where multiple chains in parallel are supporting a common piece of material. We recommend all thermoforming chains be ordered as a set, matched for length and installed as a set to prevent the material from twisting during operation.

We offer two forms of length matching:

  • Class 1 Matching: Ensures the longest and shortest chain in a set do not vary by more than 0.030″ (0.76mm) per any given length.
  • Class 2 Matching: Ensures the longest and shortest chain in a set do not vary by more than 0.020″ (0.51mm) per any given length.

Because of the configured application-specific nature, thermoforming chain is made-to-order (MTO) only.

Features & Benefits

  • Materials

    The Diamond Difference begins with raw materials that meet exacting standards for metal grade, mechanical properties, carbon and alloy content to ensure minimization of impurities that impact tensile and fatigue strength.

  • Fabrication

    Diamond designs each component to exacting dimensional standards for optimal performance. With Diamond® Thermoforming chain, we offer multiple pointed linkplate, extended pin or extended pin options to create an ideal product for each specific thermoforming application.

  • Heat Treatment

    Strict control of atmosphere, time and temperature optimize the material properties – increasing strength, durability and wear resistance.

  • Shot Peening

    Proprietary shot peening equipment was developed specifically to ensure consistent intensity and coverage of components. Shot peening adds a layer of compressive stress that helps components resist fatigue failure when exposed to repeated high loads.

  • Lubrication

    We use a proprietary lubrication process on all lubricated chains for enhanced corrosion protection and extended wear life.

  • Preloading

    Following assembly, all chains are preloaded to firmly seat the pins and bushings. This is to reduce initial run-in and extend the wear life of the chain.
