The Time Saving Value of Customization

1

Experience less downtime. Quick change tooling mounting systems provide easy changeovers that maximize production efficiency without compromising seal integrity or quality.

2

Customization guarantees a precision fit. Save tooling time while maintaining the close tolerances critical for robust, airtight, verifiable medical packaging seals.

3

Lasts up to seven times longer.  This means longer production runs using the optimized heat, pressure and dwell times vital for supply chain durability and user-friendly opening.

Gaskets and Magnetic Mounting Blocks

Common uses include rigid and semi-rigid package sealing such as blister nest or anvil support and container sealing.

  • Customization means a time-saving perfect fit for your application.
  • High precision tolerances ensure correct seal location and thickness.
  • Helps ensure high integrity seals for both rigid and semi-rigid containers.
  • Heat seal rubber that lasts up to seven times longer - just replace the custom mounts and go.

Common uses include sealing trays, tubs and cups, blister nest and anvil support, clamshells, skin pack sets and procedure sets.

  • Precision customized sealing heads ensure seal integrity by providing uniform heat sealing pressures and temperatures.
  • Magnetic mounting blocks make changeover fast and easy. Reduce downtime and allow optimized machinery to keep producing consistently strong, user-friendly seals.
  • Made with high temperature, high heat-tolerant silicone suitable for multilayer films.


Rubber Rollers

  • Exceptionally durable - made with a proprietary manufacturing process that chemically bonds the high temperature silicone to a metal core.
  • Custom rollers allow quick changeovers because the rollers match your machine's mountings. Replacement is a breeze keeping machines running at their optimized settings.
  • Precision ground roller surfaces without meeting points or seams deliver uniform, verifiable seals.


Seal Bars and Jaws

  • Thermally conductive, high-temperature silicone seal bar assemblies provide superior sealing performance.
  • Crowned design and precision tolerances eliminate leaks and create consistent, strong seals.
  • Made using high temperature, high heat-tolerant silicone suitable for multilayer sterile barrier films.
  • Teflon [®️] bonded silicone option for an enhanced release surface without the need for messy and unreliable adhesives.

 

We're here to create the perfect heat seal tooling for your application.
