Mold Release Agent Manufacturing Process-A Ultimate Guide

mold release agent manufacturing

With the rapid development of injection molding, extrusion, calendering, molding, lamination, and other processes, the mold release agent is widely used in those fields. The quality of the release agent determines whether a high-quality mold can be produced. Meiyahg has more than 20 years of mold release agent manufacturing experience, and its products are sold to more than 30 countries around the world, and have been recognized by many customers. We strictly control every step of the process of release agent. The following shows the mold release agent manufacturing process and how to choose the right mold release agent for your product.

Mold Release Agent Manufacturing Process


1、Firstly, select excellent raw material. The component of the release agent is mainly lubricant, organosilicon, and additive. In the production, the Sakurai release agent is made of top quality lubricants and silicone oil from the worldwide,e.g. Shin-Etsu, Dow, Dow Corning and other well-known manufacturers of raw materials.

2、Before putting in a warehouse, we take small samples from the selected raw material for strict testing in the laboratory. We use qualified material only.


3、During mass production, the raw materials are mixed accordingly by formula, precisely control the mixing ratio, blending, and chemical reaction.


4、Put the blended liquid into reaction equipment, setting the temperature and reaction time, proceed to the emulsification and other reaction processes. The process of full reaction is extremely important, directly affect the quality of the release agent.



5、Take a small amount of the finished product and use a testing instrument to observe whether the release agent is fully reaction and formulated. We collect the index of solid content, lubrication and other data, to compare with the standardization, and finally determine the release agent is qualified or not.


6、Apply some release agent on the mold for practical testing, to test the performance of demoulding, adhesion force,film-forming, fluidity and so on. Each batch release agent must be sampling tested, which ensure our quality conform to industrial criteria.


7、The qualified release agent is packed into various size packaging, seal up the container and stored under room temperature and ventilated condition.

How to choose mold release agent?


  • Matching selection.

There are different types of mold release agents for different products, and we should select the mold release agent matching the materials of finished products.


  • Using and applying conditions

The key factors to select the release agent include mold temperature, dilution ratio, molding time, mold structure complexity and so on.


  • Performance demands

The different mold release agents have different performance in terms of mold release force, post-processing, environmental protection, drying and cleaning time, etc. According to practical production requirements, we can choose the proper mold release agent through weighing the performance and production indicators, etc.


  • Cost efficiency

Release agent brand is numerous, and some release agents are divided into low-end, medium-end and high-end. Sakurai release agent is focused on the medium-high end of release agent production. Since our technical breakthrough, spray once mold release agent can use for several times demoulding, so it’s very high-cost performance and it can efficiently reduce the consumption cost for end-users.
