The issues of "dough sticking" and "poor mold release" leading to product shape defects in the manufacturing process of Western-style confections and food products are significant challenges that reduce production efficiency and yield. This time, we introduce an example of a metal madeleine mold with a complex shell shape (scallop shape) that has been uniformly coated with a fluororesin (PTFE) to ensure consistent film thickness down to the details. ■ Top-notch non-stick properties (release properties) Thoroughly prevents dough from sticking and burning. The baked madeleines easily and cleanly release from the mold, significantly reducing the deformation of delicate products and directly contributing to improved yield in production environments. ■ Heat resistance (continuous use temperature 260°C) The coating is resistant to degradation even under the harsh thermal conditions during baking, maintaining excellent release performance over a long period. ■ Reduction of release oil and prolongation of mold lifespan By eliminating or minimizing the application process of release oils (butter or oil) that were previously essential, we can cut raw material costs and reduce the time spent on application. This strongly supports the streamlining and automation of manufacturing lines. Additionally, it protects the surface of the mold, preventing wear and corrosion of the base materials such as aluminum and steel, thus contributing to the longevity of the tooling.

The shape defects of products caused by "dough sticking" and "poor release from molds" in the manufacturing process of Western-style confections and food are significant challenges that reduce production efficiency and yield. ■ Release Coating for Traditional Baked Goods and Gugelhupf Molds For metal Gugelhupf molds with very complex and three-dimensional shapes, such as beautifully spiraled wave patterns and central protrusions, a uniform thickness of fluoropolymer PTFE coating is applied down to the finest details. ■ Purpose of the Coating The primary goal is to impart "non-stick (release)" and "heat resistance." The coating is resistant to degradation even in the harsh thermal environment during baking, thoroughly preventing dough from sticking and corner adhesion. This allows the baked Gugelhupf to smoothly and cleanly release from the mold, significantly reducing the deformation of delicate products and directly improving yield in the production process. Additionally, it minimizes (or eliminates) the need for the application of release oils (butter or oil), leading to cost savings on raw materials and reducing the time required for application. This strongly supports the streamlining and automation of the manufacturing line.

In metal etching and chemical treatment processes, cleaning and transport mesh baskets exposed to harsh chemicals such as strong acids and strong alkalis, even if made of stainless steel (SUS), are prone to corrosion and leaching of metal components due to repeated use, posing a risk of metal contamination in the products. This technology provides a surface treatment solution that applies fluororesin (PFA) to stainless steel mesh baskets with a complex woven structure to address these challenges in manufacturing environments. ■ Technical Features - It forms a thick anti-corrosion and release layer without pinholes, reaching the intersections of the mesh and fine gaps. - The superior chemical resistance of PFA completely isolates the metal substrate from the chemicals. - The extremely high water and oil repellency unique to fluororesins dramatically improves the "drainage" of liquids from the basket surface. ■ Implementation Benefits - It prevents corrosion of the baskets over the long term, contributing to the longevity of the equipment. - It minimizes the residual adhesion of chemicals during lifting, significantly reducing carryover to the next process.

This is a surface treatment solution that applies fluororesin (PTFE or PFA) to metal food trays used in the manufacturing and processing lines of foods such as bread, side dishes, and frozen foods. ■ Technical Features - Forms a completely uniform coating without pinholes, even in the corner areas of the trays and the details of ribs (reinforcement shapes) that ensure strength. - Provides excellent "non-stick (release)" properties, thoroughly preventing ingredients such as sauces, dressings, and dough from sticking or burning onto the tray surface, even in harsh baking and heating environments. - Naturally complies with food sanitation laws, making it safe for use in areas where food comes into direct contact. It dramatically improves the yield of products by eliminating deformation of delicate ingredients and strongly supports the continuous stable production of high-quality foods. Because ingredients are less likely to remain, the time required for rinsing and cleaning after use (downtime) is significantly reduced. This not only increases the operating rate of the manufacturing line but also greatly contributes to cutting costs related to water, electricity, and labor associated with cleaning maintenance.

This is a contract processing service for fluororesin coatings for metal "long steel belts (conveyor belts)" used in large automated mass production lines that manufacture baked goods such as biscuits, cookies, and cakes. ■ Capable of handling very long workpieces (long items) that can reach several tens of meters By using our large continuous baking furnace, we ensure reliable curing under the same conditions. We form a coating film with extremely stable quality, free from color unevenness and variations in film thickness, across the entire belt. ■ Coating functions The main features are the provision of "non-stick (release)" and "heat resistance." - The coating film is resistant to degradation even in harsh thermal environments where it continuously passes through high-temperature ovens, thoroughly shutting out the sticking of delicate doughs that contain high levels of sugars and fats, as well as stubborn burning. - Finished products smoothly peel off the belt surface, significantly reducing product deformation and damage (product loss). - This surface treatment solution directly contributes to stabilizing the continuous production process and improving the overall productivity and yield of the factory.

This is a high-performance ETFE (ethylene-tetrafluoroethylene copolymer) coating contract processing service for metal fans (impellers, rotor wheels, casings, and sirocco fans) that discharge corrosive gases such as acids and alkalis in exhaust and ventilation systems of various chemical plants, semiconductor manufacturing facilities, and plating treatment plants. ■ ETFE with Mechanical Strength and Chemical Resistance Fans are constantly rotating at high speeds and are subjected to harsh conditions as "driving components," exposed to contact (friction) with dust and fine particles contained in wind pressure and airflow. Therefore, this method employs ETFE, which possesses particularly excellent "mechanical strength (hardness, impact resistance, wear resistance)" and "chemical resistance" among fluororesins. It forms a uniform coating without pinholes, reaching into the intricate gaps of the fan blades and the unevenness of welding lines. ■ Thick Film Specification that Shuts Out Liquid/Gas Penetration To prevent the penetration and permeation of corrosive gases, the coating is applied in a "thick film specification (hundreds of micrometers level)" that is thicker than standard fluororesin coatings. This protects the metal substrate from gas, preventing corrosion and premature failure of the fan. It is a reliable surface treatment solution that contributes to the longevity, safety maintenance, and stable operation of equipment in harsh exhaust environments.

This is a surface treatment solution that applies a fluororesin (PTFE/PFA) coating to the inner surface of metal "rice cookers" used in large food factories, prepared food manufacturing lines, and meal centers. By forming a non-stick fluororesin coating over the entire inner surface of the cooker, it effectively prevents the sticking and burning of "freshly cooked rice," which has a very high tendency to adhere. **Value of Introducing This Technology** - **Improved Yield During Transfer**: When rice is inverted for transfer, it falls smoothly without leaving any residue on the inner surface, minimizing product loss and remaining adhesion. - **Significant Reduction in Cleaning Labor (Downtime)**: The need for scraping off stuck-on residues is eliminated, and dirt can be removed with simple washing or light cleaning, dramatically shortening cleaning time. - **Optimal Selection Based on Application**: Depending on usage conditions such as heating temperature, cleaning frequency, and mechanical wear, we propose the best specifications with excellent wear resistance using "PTFE" or superior continuous use and weather resistance with "PFA." Of course, all paints and processing methods used comply with the standards of the "Food Sanitation Act," ensuring a safe and secure specification.

This is a surface treatment solution for the "automatic rice loosening machine" used in automatic rice cooking systems at rice processing plants, prepared food manufacturing lines, and large-scale meal centers. It involves applying a PTFE (polytetrafluoroethylene) fluororesin coating with excellent non-stick properties (release properties) to the metal "loosening blades (mixing and loosening components)" that fluff up the cooked rice. The coating forms a uniform fluororesin film even in the complex gaps of the thin loosening rods (pins) that extend radially from the central shaft component. This effectively prevents the sticking, scorching, and hardening of highly adhesive "freshly cooked rice," which contains a lot of moisture and starch. 【Benefits of Implementation】 ■ Improved Yield Reduces the carryover and residue of rice on the loosening pins, minimizing product loss and waste. ■ Reduced Cleaning Labor and Downtime Eliminates the need for scraping off or soaking stuck rice, allowing for quicker cleaning with water washing or light work, thus shortening cleaning time. ■ Safe and Reliable Quality The paint used complies with the "Food Sanitation Act," making it safe for use in environments where food comes into direct contact.

This is a surface treatment solution for metal "slitter rolls" used in the manufacturing lines of food products such as cookies, biscuits, bread, and noodles, which cuts and divides sheet-like dough into a consistent width. We apply fluoropolymer coatings such as PTFE and PFA, which have the highest level of non-stick properties (release properties), to highly adhesive dough. Using our unique precision technology, we create a uniform and smooth coating on the blade edges, roll grooves, and fine steps, effectively preventing the adhesion and sticking of sticky dough containing moisture, oil, sugar, and gluten. 【Benefits of Implementation】 ■ Prevention of chocolate stoppages and stable operation Our excellent release properties eliminate problems caused by dough sticking to the blade edges or being drawn in, preventing line stoppages (downtime) and improving operational efficiency. ■ Improved yield and stable quality Smooth separation from the blade prevents pulling and deformation during cutting, achieving uniform product dimensions and reducing defect rates. ■ Reduction in cleaning and maintenance time By preventing sticking and adhesion, cleaning tasks become easier, significantly shortening cleaning time. We will propose the optimal fluoropolymer specifications according to the dough characteristics (hardness, adhesiveness) and the usage environment.

This is a technical case of applying a fluororesin PFA coating to a metal "ink pan" used for gravure printing machines, such as those for package printing and film printing, where liquid printing ink is stored. The coating process is uniformly and smoothly applied to the bottom and sides of the ink pan, including the rounded corners and areas near the drain outlet. **Purpose of the Coating** In an environment where printing inks containing various solvents, pigments, and resin components are constantly in contact, the coating provides top-tier "non-stick" properties and "water and oil repellency." It prevents ink stains from adhering, contributing to improved operational efficiency and quality stability in the printing process. **Main Benefits of Implementation** ■ Reduction of setup change time (downtime) Residual ink does not adhere to the surface, allowing for smooth wiping and recovery during frequent color changes. ■ Decrease in cleaning labor and solvent usage To prevent sticking, scrubbing during cleaning is no longer necessary. The amount of cleaning organic solvents (such as thinners) is significantly reduced, achieving cost savings and improving the work environment. ■ Prevention of foreign matter contamination It prevents "skinning" caused by the drying and peeling of inks from previous processes, aiming to enhance product quality and improve yield.

This is a technical case study of a mesh tray made of engineering plastics (such as nylon and PPS resin) shaped by a 3D printer, coated with our low-temperature sintering fluorine-based coating "FU-1240." **Features of the Low-Temperature Sintering Fluorine-Based Coating "FU Series"** Since it does not require the high-temperature baking process (300°C to 400°C) necessary for conventional fluorine resin coatings, it can form a coating directly on resin substrates with low heat resistance, such as nylon and PPS, without causing deformation or deterioration. **Main Benefits of Implementation** ■ High adhesion to resin & elimination of thermal effects The coating is applied at temperatures below the melting point and thermal deformation temperature of the substrate. It adheres strongly while maintaining the inherent strength and properties of the resin. ■ Prevention of adhesion and sticking (improved cleanability) With excellent non-stick properties, it prevents the sticking of liquids, powders, and adhesives. Even in complex shapes like mesh, dirt is easily removed, reducing cleaning effort. ■ Improved slip properties (reduced friction and wear) By lowering the coefficient of friction, it eliminates snagging between the tray and the counterpart material. This contributes to improved sustainability in transportation and movement, as well as reducing wear on the substrate.
