The Main Function Of Mold Release Agent

Many manufacturers rely on molds to produce a large number of similar glass, rubber, concrete, metal or plastic parts and components. One of the key elements of the mold manufacturing process is the use of mold release agents, which are chemical or physical substances that prevent materials from sticking to the mold surface. The release agent forms a protective layer between the surface of the mold and the material, and plays a role equivalent to the engine oil in the automobile engine.

The composition of the release agent may be based on solvent or water. Solvent-based reagents are traditional formulations, which contain various chemical substances, these substances will produce a material release process. Newer demoulding techniques rely on the use of water-based reagents because they provide safer and more environmentally friendly options.


The main function of release agent
In addition to forming a protective barrier, the release agent also has the following functions.

Impact finish characteristics
In general, the mold release agent should not have any effect on the part, except that it can be detached from the mold. However, the choice of release agent may change the characteristics of the release part. For example, certain agents can produce matte or glossy finishes. Therefore, it is important to understand the effect of the agent on the type of release agent material before use.

Reduce production time
Mold release agents can help manufacturers adhere to strict production plans by increasing the flow rate of materials during the molding process and reducing the overall molding cycle time. Increased production efficiency can also save manufacturers a lot of costs.

Produce slip effect
Certain types of mold release agents can create a "slip effect" in specific areas of the mold, thereby promoting mold release. Several different release agents can be combined to produce different degrees of slip in different areas of the mold.

Protection products
If a release agent is not used, the product may fuse to the mold, which may cause damage and render it unusable or unsaleable. This may also result in wasted material, which incurs additional costs.

Promote cleanup
By preventing the material from sticking to the mold, the release agent can be cleaned faster and more efficiently after the molding process. This saves time and helps manufacturers reduce labor costs.

Affect the service life of the mold
Regular use of mold release agents will help maintain overall process efficiency between regularly scheduled maintenance cycles, thereby maximizing the life of the mold and avoiding premature replacement.
