Release properties refer to the characteristic of materials or products that allows them to be easily removed from molds or forming tools without sticking. This property is important in the manufacturing process and affects product quality and production efficiency. ■ Methods to Improve Release Properties By applying a release agent to the surface, a thin film is created between the mold and the product, preventing adhesion. Silicone and fluorine-based release agents provide excellent release properties for many materials. ■ Resin Coating Applying a resin coating to the surface exhibits non-stick properties, making it easier to remove the product. Fluororesin coatings are commonly used. ■ Metal Plating For example, chrome plating has high hardness and is less reactive with other substances, aiding in product removal. Fluororesin-containing types of plating also exhibit non-stick properties. ■ Surface Roughness Adjustment By designing the surface with fine uneven structures, the contact area is reduced, thereby decreasing adhesion. As mentioned above, there are various methods, but we will introduce surface treatment technologies and coatings that are particularly effective in enhancing release properties, reducing product defects, and improving productivity.

■ The "Non-Stick Property" of Fluoropolymer Non-stick property refers to the characteristic of being easy to release and not adhere, or to adhere less, even to strongly adhesive substances. For example, fluoropolymers excel in water and oil repellency, have a large contact angle, and possess a property of being difficult to wet due to their molecular structure. The measure of wettability, "critical surface tension (γc)," is extremely low for fluoropolymers, making it easy for liquids to be repelled and difficult to wet. Coatings that utilize this functionality are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Reference Data on Non-Stick Property】 ■ Contact Angle of Water (°) PTFE ... 114 PFA ... 105-110 FEP ... 115 ETFE ... 96 ■ Contact Angle of n-HD (°) PTFE ... 34-45 PFA ... >45 FEP ... 41-45 ETFE ... 28 ■ Surface Free Energy of Solids (dyn/cm) PTFE ... 18.5 PFA ... 17.8 FEP ... 17.8 ETFE ... 22.1 *For detailed information on non-stick properties, please download the PDF or contact us.

We would like to introduce a coating that can solve the problems caused by adhesive from packaging films adhering to cutter blades. In one packaging machine, packaging films with adhesive frequently adhered to the cutter blades, resulting in poor cutting performance and film sticking to the blades, causing misalignment and necessitating line stoppages. This issue prevented us from achieving the production quantities calculated from the takt time. Initially, a release agent was applied, but its effects did not last, requiring repeated applications. Therefore, we adopted the silicone-based coating "MRS Coating." The coating eliminated adhesive adhesion, and since the processing temperature is below 250°C, there were no concerns about blade dulling. Additionally, the 1-micron thin film maintained the sharpness of the blade edge. [Key Points of the Case] - Purpose of Surface Treatment: Quality improvement, operational stability, speed enhancement, compliance with safety and environmental requirements - Required Functions: Non-stick, release properties, long lifespan - Treatment Adopted: MRS Coating (Mold Release Silicone) ▼ Free samples of improvement cases for the cutting process and trial sets are currently available on the site below! ▼

■What are the issues with release agents? Release agents are known to be applied in industrial fields to improve the separation of molded products from molds. In addition to facilitating mold release, release agents also need to have properties that make them resistant to degradation from heat during molding and minimize contamination of the mold. Silicone is often used as a release agent because it has high heat resistance, does not easily degrade with repeated heating during molding, has low surface tension which provides good wettability to the mold, and can reach every corner of the shape. While silicone release agents have excellent effects, they can also impose a burden on the working environment, increase the effort required for mold cleaning, and lead to variations in the amount applied by workers, which may negatively impact the final product. ■Silicone Coating Technology Silicone coating technology balances release properties and maintenance, leading to solutions for release agent issues. ▼For more details about the coating, please click the URL below or contact us.

Wear refers to the phenomenon where one or both of two objects in contact and moving against each other become abraded. There are two main types of wear that can occur in manufacturing environments. One type is "rough wear," which occurs when surfaces are abraded and eroded due to contact with rough surfaces or particulate matter. The other type is "thrust wear," which happens when surfaces adhere due to frictional heat and are worn away by the opposing material. The appropriate surface treatment varies depending on the type of wear.
