As an indispensable part of industrial manufacturing, the control of release film's peeling force has a significant impact on product quality and production efficiency. Correctly understanding and managing the peeling force of release film can effectively avoid material residue and damage, and improve the stability and reliability of production.

The peeling force of high temperature release film refers to the force required to separate the film material from the mold surface during the manufacturing process. Its main function is to protect the surface of the mold from adhesion of resin or composite materials, thereby ensuring the surface quality and accuracy of the product. The magnitude of the peeling force directly affects the demolding performance and production efficiency of the release film. Excessive or insufficient peeling force may lead to adverse consequences such as material residue or premature demolding.

Factors affecting the peeling force of release film

The selection of release film materials: Different materials have different surface characteristics and friction coefficients, which directly affect the magnitude and stability of the peeling force.

Surface treatment: The treatment methods for the surface of the mold, such as polishing, coating, or special treatment, can affect the contact area and adhesion between the release film and the mold, thereby affecting the magnitude of the peeling force.

Temperature and humidity conditions: Changes in temperature and humidity during the manufacturing process can affect the hardness and flexibility of release film materials, thereby affecting the control of peel strength.

Process parameters: including the setting of manufacturing process parameters such as pressure and speed, which directly affect the mechanical properties and demolding effect of the release film during the peeling process.

To avoid residue or damage to the product surface during the demolding process of the release film, the following effective measures can be taken:

Choose the appropriate release film material: Based on the specific manufacturing process and product requirements, select a release film material with appropriate peeling force and good demolding performance. For example, silicone film may be more suitable than PTFE in certain situations due to its lower peel strength and ease of control.

Optimize surface treatment: Ensure that the mold surface is smooth and clean, and perform appropriate surface treatments such as polishing or special coatings to reduce friction with the release film and improve the stability of the peeling force.

Adjusting process parameters: Based on the actual production situation and product characteristics, optimize manufacturing process parameters, including temperature, pressure, and demolding speed, to ensure that the release film can achieve good peeling effect under optimal conditions·

Regular maintenance and replacement of release film: Regularly inspect and maintain the condition of release film, timely replace aging or severely worn release film to ensure its performance stability and long-term use effect.

In actual production, many enterprises have achieved significant production benefits and product quality improvements by regulating the peeling force of release films

A certain electronic manufacturing enterprise: By using customized silicone film, the peeling force is precisely controlled, avoiding damage and material residue problems of electronic components during packaging, and improving production efficiency and product reliability.

Automotive parts manufacturer: Using PTFE film with low surface energy effectively reduces peeling force and mold surface wear, optimizing the production environment in the composite material manufacturing process.

These cases demonstrate that by scientifically and reasonably regulating the peeling force of release films, problems such as material residue and difficulty in demolding can be effectively solved, and the manufacturing quality and process stability of products can be improved.
