Heat Seal Part Holding Fixtures
Learn about our fixtures, benefits and options.
Smarter Seals & Enhanced Efficiency
Silicone Part Holding Fixtures (also commonly referred to as platens or anvils) hold your rigid packaging application in precise alignment with your film or lidding stock to ensure repeatable high-quality seals.
Silicone Fixtures Market Leader
At United Silicone, we are proud of our reputation as the market-leader in precision fixtures.
Several features of our Silicone Part Holding Fixtures are unique-in-the-market and provide key performance benefits.
Benefits
Superior Seals, Less Hassle
Our Silicone Part Holding Fixtures precisely align your rigid packaging component with the lidding film and metal seal head for repeatable, high-quality seals. Additional benefits include:
| Eliminate Leakers | Our continuous silicone avoids “leakers” caused by extruded silicone lengths that are joined together. |
| Hassle Free | Our thermally conductive formulations are heat tolerant up to 550°F. They will not become “gummy” or “sticky” when exposed to heat seal temperatures. |
| Superior Bond | Our proprietary silicone-to-metal bonding process provides unmatched adhesion without the need for cumbersome adhesives. |
| Repeatable Performance | Our part holding fixtures are custom molded for superior precision. |
Eliminate Need for Teflon Tape
Teflon Bonded Silicone
Safety
- Operators do not need to handle very hot fixtures to install or change Teflon tape
Time Savings
- Lasts 7x longer than Teflon tape
- Faster changeovers (see video)
- Unmatched adhesion
- No need for adhesives
Enhanced Seal Integrity
- Resistant to contamination (food contamination, thick film, product dust or particulate)
- Helps reduce leakers
- Thermally conductive for improved heat transfer
Options
Each Silicone Holding Fixture is painstakingly designed to meet unique application requirements. We offer both bonded and unbonded (commonly referred to as gaskets) part holding fixture solutions.
Bonded Part Holding Fixtures
We can build a complete bonded fixture or use your existing base to create a part holding fixture designed for optimal performance in your application.
- Using Your Fixture Base
Proprietary, adhesion free process to bond our high performance silicone or Teflon/Silicone to your metal fixture - Entire Bonded Fixture
We can design the most efficient fixture design for your application. We CNC engrave steel, stainless steel or aluminum bases with coating options prior to applying our silicone formulation.
Unbonded (Gasket) Part Holding Fixtures
We offer unbonded silicone gaskets as well as unbonded metal holding fixture bases.
- Silicone Gasket
Advanced, continuous silicone parts prepared with T-slot or mushroom mount features on the underside for simplified attachment to your fixture base. - Metal Base
CNC engraved steel, stainless steel or aluminum bases.
Foundations & Formulations
We offer a wide range of foundations and formulations to ensure our part holding fixtures are designed for optimal performance in your unique application. Choose from steel, stainless steel and aluminum bases together with a variety of heat tolerant or high strength silicone formulations.
