Hot stamp dies carry graphics that are transferred via pressure to the surface of a product or component.
A number of different types of silicone stamping dies are available. The shape, format, and construction of your silicone stamping die should be carefully selected to meet your unique performance needs.
For superior repeatability print-to-print and batch-to-batch, it is essential to select a die shape perfectly suited to your project. Both the geometry of the product or component to be decorated as well as the requirements of your specific artwork should be considered. If you have combination graphics, a dual durometer die could be helpful. Finally, it is helpful to consider whether you need die made from a photo-etched or machine-engraved mold.
CER offers the following types of silicone stamping dies:
|Flat||Vertical stamping, peripheral and roll-on applications|
|Contoured||Decoration that precisely matches a contoured part|
|Crowned||Eliminate air entrapment or to allow for heat sinks in plastic parts|
|Multi-level||Accommodate small height differences in parts to be decorated|
|Single Durometer||Dies ranging from 50 to 90 durometer to meet a wide variety of needs|
|Dual Durometer||Enhanced capability to stamp combination of fine and bold graphics or better conformity to part variation|
Silicone dies can be either photo-etched or machine engraved. CER specializes in machine engraved dies. There are several instances where machine engraved dies will provide superior results.
The first instance is when multiple reliefs are required for full part contact and/or support for character integrity. PhotoEtching produces a single relief. CNC engraving facilitates multiple reliefs and shapes such as crowns and full contours to match the shape of a part.
A second instance where Machine Engraved Molds may provide superior results is when vertical sidewalls are required for part clearance and/or precision foil transfer of lines or characters. CNC engraving (Machine Engraved Molds) provide this ‘control’ and repeatability from Die-to-Die.
Finally, Silicone Dies from Machine Engraved Molds are highly accurate and repeatable from Die-to-Die. For example – a Die used to stamp the lines of a ruler or another measuring device must create a finished part accurate to that scale of measurement. In other words, a hot stamped ruler must actually measure to 12 inches NOT 11 and 7/8!
CER offers different silicone formulations each carefully engineered to meet specific performance requirements. Our Ultrasil Formulation is well-suited for demanding vertical and peripheral applications that require temperatures as high as 550 degrees Fahrenheit and/or high pressure. Typically Ultrasil is used in manually fed situations. Our second silicone formulation is called Thermosil. Like- Ultrasil, Thermosil offers exceptional heat resistance up to 550 degrees Fahrenheit. Thermosil also offers rapid heat recovery- making it well-suited to automated applications.
Unique-in-the-industry, CER´s tool-less “Quick-Change” magnetic die mounting fixtures provide industry-leading changeover speeds and repeatability.
With Magnetic Die Mounting Fixtures, die changeover and set-up time is dramatically reduced. Magnetic die holding fixtures mount to your machine, allowing dies to be easily affixed eliminating the need for screws to secure the hot stamp die and providing
Improved Mounting Accuracy
Magnetic dies improve repeatability from die-to-die offering increased production and reduced downtime. The same pin and slot locations are used in both the die-holding fixture and the die to guarantee precision artwork alignment from die-to-die. In fact, Magnetic dies provide
Though the hot stamp and heat transfer decoration processes are very similar, a difference can be seen in the dies used. The molds used for hot stamp dies carry the image to be used. They are more complex than the molds used for heat transfer decoration where no graphic image is carried on the die (the image comes from heat transfer label itself).
Ensuring high-quality hot stamp decoration depends upon having BOTH artwork carefully designed for the application as well as Dies manufactured utilizing specifications tailored to the graphic’s requirements!

CER dies provide market-leading efficiency. For example, our magnetic quick change dies allow for dramatically faster changeovers and improved mounting accuracy.
Unmatched Art Expertise
CER has cutting-edge art reproduction capabilities to ensure customers have the tools needed to achieve highly repeatable, superior decoration that will allow them to stand out in a crowded market.
In addition to being able to provide you with expert advice on the type of silicone die best-suited to your unique application, a quality die supplier should provide:
Top die manufacturers should provide CNC machine engraved molds with crown or contoured surfaces to perfectly match part shapes/configurations.
Die Finishing Services
These should include hole drilling, matching dovetail, and special trims. Quality manufacturers can save you time by providing a completely “ready-to-use” die.
Graphic Arts Expertise
Finding a die supplier with significant Graphic Arts Expertise eliminates “lost in translation” errors when it comes to manipulating and creating your artwork.
Please get in touch. We would love to hear from you.
