For Challenging Mold Structures

A Permanent Coating that Lasts the Life of Your Mold

As mold release processes have become more difficult due to advanced materials and increasingly complex designs, there is a growing need for mold releases that won’t compromise mold integrity or harm product features. GVD offers RapidRelease, a fully automated coating process that delivers a permanent, non-stick mold release for a range of molds from delicate, micro-textured products to some of the most difficult to manufacture passenger, light truck, commercial, winter, and Nordic tires. Incorporating RapidRelease into manufacturing processes allows designers to integrate more complex geometries and material compounds, while dramatically increasing product quality and reducing persistent downtime for maintenance and cleaning.

Enables Advanced Design

RapidRelease allows designers to incorporate cutting edge technologies by cleanly demolding even the most challenging designs and compounds.

Compatible with all Venting Strategies

RapidRelease is compatible with all venting strategies, including spring vents. The coating is  thin enough to be applied without the removal of vents and does not affect airflow or mold tolerances.

Improves Product Yields

RapidRelease eliminates sticking and material flow issues, drastically reducing scrap and downgrade rates.

Increases Uptime

A “set it and forget it” solution. RapidRelease eliminates operator intervention from mold cleaning or application of release sprays.

Maintains Part Appearance

This ultra-thin coating conforms to the mold geometry, mimics the mold surface, and will have no impact on the part finish.

Protects Mold Integrity

Unlike traditional PTFE coatings, RapidRelease is applied at room temperature, eliminating negative effects on the mold.

RapidRelease FAQs

RapidRelease is typically applied at 2-10 microns, but can be applied as thin as 50 nanometers. RapidRelease is so thin that mold vents are not clogged and mold tolerances are not affected. GVD will work with you to determine the ideal thickness for your application.

RapidRelease is so thin that it will not affect mold or vent tolerances. RapidRelease can be applied to all venting styles, including spring vents.

GVD’s coating technology utilizes vacuum deposition techniques. Substrates must be vacuum compatible, meaning they will not outgas, shrink, or expand when exposed to a mild vacuum environment. Metals, glass, ceramics, and most plastics can be coated.

There are many factors that determine how long the coating will last such as the curing compound, mold complexity, press style, curing process, etc. For tire molds, we typically see 4000-6000 cures, but have also gotten well over 10,000 cures. If unused, the coating will keep indefinitely. There are also no negative effects if the mold is taken out of production and then put back in at a later date.

GVD’s PTFE coating is chemically identical to bulk PTFE, polytetrafluoroethylene. PTFE is a widely-used polymer that has unique properties including lubricity, excellent release characteristics, high chemical resistance, and hydrophobicity.

RapidRelease coating consistently improves tire quality by preventing blemishes, defects, and lightness on the molded part. The coating also helps the part to look more uniform. Also, because the coating is so thin, it will not affect the appearance of the part. This is unlike “traditional” PTFE coatings that are much thicker and will smooth the surface features on the mold, causing the molded part to appear shiny and blemishes to be more noticeable. The RapidRelease coating does not have this effect.

Learn How RapidRelease Helps Tire Manufacturers Improve Their Process

As tire manufactures advance their designs, tread patterns are becoming more complex making the tires increasingly difficult to remove from the mold. That’s where RapidRelease can help.
