Silicone Coated Tooling

Custom silicone tooling offers a unique solution for various applications where traditional tooling does not deliver the desired results. From versatile silicone sheet stock to precision-ground rollers or compliant grippers, these tools deliver efficiency through proper design, testing, and repeatable manufacturing.

ISM offers a wide range of silicone tooling solutions, from bonded and un-bonded fully cured silicone sheets to silicone coated tooling that’s customized to your specific needs and existing equipment. Our chemically bonded and thermally conductive silicone provides ideal heat distribution for high quality stamps and reliable seals.

From hot stamping and robotic grippers to heat sealing and material handling, silicone tooling is as versatile as the silicone itself. Additionally, silicone’s natural non-stick nature makes it a viable option for industries like laboratory/medical and food and beverage that are concerned with preventing chemical leeching.

Silicone Coated Rollers

Engineered with precision, our silicone coated rollers readily conform to surface variations in molded plastic parts, ensuring the smooth application of hot stamping foils and multi-color heat transfers. Other customers have found success using these as conveyor rollers or nip rollers to move materials through a process.

Because of the thermal conductive properties of our silicone and the seamless surface, our rollers are the ideal choice for a wide range of applications, including banding, laminating, printing, and decorating.

• Face lengths up to 120 inches
• Finished OD up to 20”
• Seamless surface in flat, contoured or stepped profiles
• Aluminum or stainless-steel cores
• Cores and existing rollers are potentially recoatable

Silicone Coated Seal Bars & Seal Heads

Seal bars and seal heads play pivotal roles in achieving superior seals in flexible and rigid packaging applications. Thermally conductive silicone seal bars, also known as "jaws," work in tandem with metal surfaces to create high-quality seals, ensuring product integrity and security. Meanwhile, silicone seal heads, custom-molded to your specifications, facilitate precise alignment between hard (metal) and compliant (silicone) tools, enhancing seal quality and repeatability.

• Conforms to part thickness, including zippers and multi-layer films.
• Custom-molding eliminates the need for machining sheet materials.
• Thermally conductive silicone ensures superior heat seal performance.
• Compression-molded silicone offers 4x superior thickness tolerances with consistent material dispersion.
• Available in smooth or textured surfaces.
• Crowned designs eliminate air holes and leakers, ideal for long seal bars.
• Easy film release may eliminate the need for Teflon Tape, with high heat tolerance up to 550°F ensuring silicone remains non-sticky.
• Teflon Bonded Silicone provides an adhesive-free alternative with extended lifespan, particularly suitable where small particle contamination is a concern.

Hot Stamp Holding Fixtures

Holding Fixtures (also known as Nests and Die Mounting Blocks) form the essential foundation for successful hot stamp and heat transfer applications. These fixtures ensure precise alignment between your part and the stamping die, which is crucial for achieving repeatable, high-quality decoration.

We are renowned for market-leading precision fixtures, offering a comprehensive range of die and part holding fixtures for hot stamp, heat transfer, and Polyfuze® applications. These fixtures are compatible with a variety of equipment, catering to both manual and automated systems alike.

• Flat, Contoured, or Multi-level
• Aluminum or Steel base and backing
• Traditional Mounting, Magnetic, or Dovetail
• Able to be heated for efficient heat-transfer between dies

Silicone Stamping Dies

Silicone stamping dies, known for their high efficiency and quality, excel in delivering high-impact visual performance with foils and transfer labels. Dies are manufactured to your specifications, with a range of shapes including flat, contoured, crowned, and multi-level mold options. Due to our unique silicone formulations, our dies excel at conforming to surface variations with single or dual durometers. The combination of our materials and manufacturing methods results in high-impact visual performance with foils and transfer labels.

• Select silicone dies can be re-coated for repeated use, generating significant cost savings.
• CNC machine-engraved molds offer high precision and multi-relief capability.
• Magnetic mounting is optional, increasing placement accuracy while reducing change over time.
• Photo-etched molds are cost-effective with fast turnaround times.

Robotic End-Of-Arm-Tooling Grippers

Silicone-coated robotic gripper tips provide a non-marring surface for delicate and high-precision handling tasks. Our silicone coating is available in a wide range of durometers, offering a grip surface that conforms to the contours of the part being picked. Our silicone is chemically bonded to EOAT tips resulting in a longer life compared to a rubber surface applied using an adhesive.

Our team will work with you to develop custom gripper tips tailored to your specifications and operational needs. We also coat existing tooling if you already have grippers that fit your application.
