Mold release agents

Poor mold release in injection molding can slow production and result in scrapped parts – lowering the efficiency of production.

When parts are having trouble releasing from tooling, mold release agents can be utilized. These help parts release from the mold and avoid the need to re-design tooling or part geometry.

Release agents include sprays, brush-on compounds, and coatings.

Mold release sprays

Mold release sprays are commonly used to deal with resins that are sticking to tooling or parts that are being damaged during release. Various formulations are available for use with certain types of resins.

These spray-on products are applied repeatedly during production. Some mold release sprays have to be applied before each cycle, or shot, (known as “sacrificial”) while others may last several cycles before requiring re-application (known as “semi-permanent”).

Mold release sprays provide a low-cost solution for sticking parts, however they require frequent re-application and may also leave residue on the molded part. In addition, they can contribute to buildup on the mold cavity and require cleaning more often. 

Dicronite® for mold release

Dicronite® is an effective mold release agent for harder plastics. As a mold release coating, Dicronite® lasts far beyond the lifetime of any spray or brush-on release agent.

The result is improved mold release without the need for frequent re-application. In addition to improving resin mold release, Dicronite® also promotes resin flow in the mold.

Use Dicronite to: 

Reduce Maintenance Cost

Reduce Scrap Rates

Reduce Cycle Times

Improve Mold Flow

Dicronite® is easily integrated into plastic injection molding processes because of its: 

  • High temperature stability (up to approximately 540°C)
  • Use with precision tolerances (0.5 micron or 0.0002 inch thickness)
  • Biocompatibility per select ISO-10993 testing (typically suitable for food and medical applications)
  • Application on all metals and on top of many other coatings/platings
  • Ability to be re-applied on the same tool
  • Use on mirror finish mold cavities

Dicronite® is also used on other tooling for plastic injection molding. Check out our plastics page for more information.

Sliding Wear

Sliding wear occurs when two surfaces slide against one another causing material loss to one or both surfaces. Over time, this can result in component failures, additional maintenance, and costly down time.  

Coating components with Dicronite® can help minimize this wear and reduce the need for maintenance and down time.

Tight Tolerance Lubrication

Extremely tight tolerances can present challenges when lubricants or coatings are needed to reduce friction. Many products are available to help reduce friction, but in the case of very tight tolerances, few can be integrated without the need for adjustments.

Dicronite® has an average thickness of 0.5 microns (0.00002 inch) or less. This precision thin film allows users to incorporate Dicronite® on designs with tight tolerances without the need for design or manufacturing changes.

Vacuum Environment Lubrication

Vacuum environments present a challenge for lubrication. Many conventional lubricants aren’t effective under vacuum and are largely vaporized.

Dicronite® can be used in vacuum to reduce friction where other lubricants can’t function. The outgassing of Dicronite® under vacuum conditions is well below screening levels for spacecraft materials per ASTM E595.

Energy Lost to Friction

Friction is wasted energy! Systems with critical mechanical power output need to be extremely efficient.

Dicronite® optimizes mechanical efficiency by reducing friction losses and can even work in tandem with existing lubrication to further optimize efficiency.

Dicronite® is especially useful in precision systems, extreme environments, or where minimizing size and weight is vital.

Fretting

Fretting is a unique form of sliding wear that occurs when contact surfaces oscillate over a very small range of motion. Although it may seem minor, this surface wear can ultimately lead to fatigue cracking and devastating damage.

Dicronite® helps remedy fretting by providing lubrication at contact surfaces. This effectively reduces the wear and surface stresses that cause so much damage.

Dicronite® can be integrated into existing designs and assemblies without any other adjustments for seamless reduction of fretting wear.

Extreme Temperature Lubrication

Extreme low or high temperatures can be challenging environments for lubrication. At low temperatures, conventional lubricants may be too viscous to be effective, while extreme high temperatures can result in breakdown of the lubricant.

Dicronite can be used in extreme environments to ensure effective lubrication while also being used in combination with oils and greases.

Dicronite is stable across a wide temperature range:

  • up to approximately 538°C (1000°F) in air
  • up to approximately 1316°C (2400°F) in vacuum
  • down to approximately -188°C (-305°F)

Excessive Heat from Friction

As friction in an assembly generates heat, elevated temperatures can result in unwanted operating conditions.

This can cause overheating and accelerate the breakdown of materials, resulting in costly maintenance and down time or destructive failure.

Proper lubrication can help minimize friction, reduce heat, and increase mechanical efficiency. Coat parts with Dicronite® to avoid excessive maintenance and ensure components will run as efficiently as possible.
