[Resin Molding Solution Case] Non-stick Coating for PET Blow Molding Molds

No worries about the coating film peeling off and contaminating! The transparency of the PET bottle has also improved.

We would like to introduce a case study of surface treatment for molds used in blow molding PET resin. ■Challenges In the molds used for blow molding PET bottles, a coating was applied to improve release properties, making it easier for the resin to detach after molding. However, with the previous coatings, there were instances where the resin, softened by heat, would slightly adhere and remain, potentially leading to cloudiness in the PET bottles, necessitating frequent maintenance of the molds. ■Effects of the Adopted Coating We adopted our "Super Bi-Coat NYK-01-F05." This coating maintains performance characteristics such as film thickness precision and hardness comparable to previous bi-coats while improving release and slip properties during high-temperature molding. It reduces resin residue on the molds and enhances the transparency of the PET bottles. 【Key Points of the Case Study】 ■Purpose of Surface Treatment Reduction of work loss, stabilization of quality and operation ■Required Functions Non-stick and release properties, sliding and slip properties, wear resistance ■Adopted Treatment 'Super Bi-Coat NYK-01-F05' *For more details, please refer to the PDF document or feel free to contact us.

[Surface Treatment Example] Solving the sticking of transport robots with release coating.

Achieving high-speed transport with robots. Improving adhesive troubles that hinder automation with fluorine and silicone-based release coatings.

■Sites Requiring Surface Treatment - Due to adhesion to transport claws and placement platforms for transported items, it has been difficult for grasped items to be released, hindering automation on the line. - Transport processes involving resin parts and hot melt adhesives before they cool and solidify, as well as label adhesive areas and food, are in a state that easily leads to sticking. ■Points of Innovation - By applying the appropriate coating, it is possible to prevent sticking of transported items. - Adhesion issues during transport are not easily resolved through soft solutions like teaching, and even if a release agent is applied to specific areas, its effectiveness can diminish quickly depending on the usage environment, necessitating frequent reapplication and increasing manual labor. In contrast, coatings improve sticking efficiently, have high functional durability, and expand the areas where robots can operate in fields requiring automation. ■Examples of Coatings for Improving Robot Transport Adhesion Issues - Bi-Coat(R) - MRS Coating (Silicone Coating) - Fluorine-based Silicone Convex Coating - Teflon(TM) Fluororesin Coating *For more details, please download the PDF or feel free to contact us.

[Automotive Industry Case] Mold Parts Release Surface Treatment - Strong Non-Stick Coating

Shortening of takt time, which seemed impossible. Increasing production by demolding before it solidifies. Coating to prevent adhesion of molten resin to the ejector pins.

In a certain automotive parts molding process, there was a request to shorten the molding time in order to accommodate increased production. ■Concern When attempting to demold the resin from the mold in a shorter time than usual, a problem occurred where the resin had not yet solidified sufficiently, causing the ejector pin to get stuck and not come out. Therefore, a coating that improves resin demolding was considered. ■Request This mold requires strict dimensional control, and under conditions where even slight dimensional changes such as thermal distortion are not permitted, the conventional Teflon (TM) coating was not selectable due to its high processing temperature of 400°C and insufficient dimensional accuracy. ■Challenges to be solved - Improvement of production efficiency - Reduction of defects - Shortening of work time ■Coating that solved the issue 'Bicoat (R)' *For details on how the issue was resolved, please download the PDF or contact us.

It is possible to perform treatments that do not adhere even with adhesive tape. The high release properties are also beneficial for mold processing.

In the manufacturing process of resin-based products such as films, the fineness and characteristics of the roll surface are crucial for product quality. Of course, the synergistic effect with the finishing polishing treatment is also significant, but certain types of ceramics have very high release properties against plastics and molten glass, and when sprayed, they can meet quite stringent requirements for scratch resistance and surface roughness. In extreme cases, it is even possible to treat surfaces so that adhesive tape does not stick. The high release properties are also beneficial for mold processing.

[Case Study] Improvement of Mold Release for Molding Dies! Non-Stick Coating for Aluminum Molds

What is the coating used to release rubber products that tend to stick from molds? We will introduce case studies of solutions through the surface treatment of molding molds.

■Concern When molding rubber of different materials in layers, the products molded in the mold enter the vulcanization process while still in the shape of the mold. The products were made of materials that easily adhered to the mold, resulting in a phenomenon where they stuck to the mold and could not be removed after vulcanization. ■Background During demolding, strong forces are applied, so using standard fluororesin coatings posed a risk of peeling due to insufficient film strength. We recommended a Bi-Coat that excels in release properties and wear resistance, but the mold in question was made of soft aluminum and required surface treatment compatible with sulfur vulcanization, necessitating the selection of a Bi-Coat treatment that could adapt to both conditions. ■Coating Adopted Super Bi-Coat NYY-11-F05 ■Adoption Process and Effects We tested a Bi-Coat suitable for aluminum substrates and usable for sulfur vulcanization. Initially, demolding was good, but rubber adhesion began to occur within a short period. Therefore, we proposed and tested the "Super Bi-Coat NYY-11-F05," which excelled in release properties, achieving both initial demolding and sustained release properties. This led to its adoption. *Product data PDF is available for download.*

[Case Study] Coating that extends the lifespan of polypropylene heat-welded sheets by five times.

We will introduce examples of the use of non-stick coatings that last five times longer in release effect compared to fluoropolymer coatings.

■Concern In the heat plate welding of polypropylene sanitary products, thread pulling is likely to occur, making a non-stick (release) coating on the heat plate essential. The customer was using a PFA coating, but it deteriorated quickly, requiring the heat plate to be replaced in about a week. ■Background In this case, where repeated contact/release with components occurs at high temperatures, the effectiveness of the coating diminished rapidly. Replacing the heat plate and reprocessing the coating requires adjustments to the equipment and preparation of spare parts. A coating that excels in non-stick properties and lasts longer in high-temperature environments was needed. ■Adopted Coating FSR (Fluoro Super Release) HR-372AP ■Adoption Process and Effects Yoshida SKT prepared several samples, including the "FSR coating," which was developed with the concept of excellent release properties at high temperatures. Before the actual machine test, we confirmed the release properties of these samples at our company, and it was decided to conduct a practical test with the "FSR coating," which has a proven track record in high-temperature environments. The release effect lasted over five times longer compared to the previous PFA coating. The lifespan of the coating was excellent, and it was adopted.
