Mold Release Technology

Mold release technology: mold wash, mold lubricants and parting agents are substances used in traditional technology for decades. When applied onto mold
cavity surfaces, they help to prevent melt (molten resin) from sticking to such surfaces. This is called external mold release.

External Mold Release Agents

The common components of external mold release substances are silicone and flourocarbon compounds. These form a temporary barrier that prevent resin 
from securing itself to surface crevices, etch marks and pores.

This mold release process is dependant upon repetitious application of mold release substances onto mold cavity surfaces after every few cycles. But in molds with rough or textured surfaces, complex profiles or corners with tight-angles, mold release substances must be re-applied after every single cycle.

Internal Mold Release Agents

Now, let's discuss another type of Mold Release Technology: internal mold release.
It is the method of adding mold release substances when resin is being compounded.

When this is done, resins become less sticky and release from molds more easily. These types of substances are usally surface active materials consisting of fatty alcohols\amides, esters and waxes that usually migrate from surface to surface.

And while this form of mold release needs no repeated application process, it does have a downside. It readily coats the surface of the finished part and prevents adhesion or bonding. Even after thorough washing, the surface active materials in
the resin have a tendency to continually seep out onto plastic surfaces.

Platings and Coatings

Platings and coatings are primarily used for abrasive glass-filled and ceramic compound resins. Though the rate of wear and tear is reduced, sticking problems
still exist.

Traditional mold release technology agents, mold wash, mold lubricants, mold waxes and parting agents also do not significantly solve these problems.

Hard chrome platings are only used to harden and smoothen mold cavity surfaces. However, electro-plating replaces large pores with smaller pores. So parts still do
stick to, and get stuck in, molds.

Chemical Vapor Deposition (CVD) and Plasma Vapor Deposition (PVD) also seek to harden and smoothen mold cavity surfaces. And while there is an improvement compared to hard chroming, these coatings are expensive and do not last long. As with hard chroming, minute pores and etchmarks cause sticking problems.

For re-coating, the remnants of the old coating must first be removed before a
new coating can be deposited. This is both a difficult and expensive process. 


Nanomouldrelease is the new Mold Release Technology solution that
succeeds where others have failed. It is a microscopic mesh-like coating adheres
to substrate surfaces while repelling oil and water at the same time. It is also gas permeable.

It greatly reduces friction and the effects of abrasion by filling up all pores,
etchmarks and cavities regardless of their size. When all these surface
imperfections are filled up, resin cannot find points of resistance on such

Nanomouldrelease allows resin to glide over substrate surfaces, thereby
greatly minimizing friction and the effects of abrasion. Mold release problems
such as sticking and parts-stuck-in-mold are also resolved. Sticking caused by
tight-angled corner and complex corners are also resolved.

In some cases, Nanomouldrelease has enabled production cycles to go on for
more than 100,000 cycles without the use of mold release agents.

There are also no problems of cross-contamination, chipping or flaking.

Nanomouldrelease is the new effective means of mold release technology.
So stop using mold wash, mold lubricants, mold waxes, parting agents today.
Use new mold release technology.
