There was a consultation regarding the issue that when cutting tape used for product packaging, the adhesive from the tape sticks to the blade, making the packaging process not smooth. In response, we proposed that by applying a water-repellent coating to the surface of the cutter blade, we could improve release properties and prevent adhesive adhesion. We applied a surface treatment agent to all sides of the cutter blade, forming a fluororesin film. As a result, it was possible to use the blade while maintaining the film's effectiveness for 10 months. It was reported that as the usage period extended, the effectiveness of the water-repellent film gradually diminished, leading to a decrease in release properties. However, the water-repellent coating applied received positive feedback for its long lifespan, and we have been receiving regular coating requests. 【Overview of Tape Cutter Blade】 ■ Size: Approximately 3mm × 20mm × 3mm ■ Material: Stainless Steel *For more details on this case, please refer to the related link.

The shearing blade used to cut thick metal plates for car bodies has a short replacement cycle of three months, and there was a request to reduce the frequency of blade replacements to improve productivity. In response, we proposed a Tin film coating. We carefully moved the heavy shearing blades to avoid drops and impacts, and performed processes such as "incoming inspection," "pre-treatment and cleaning," "setting onto a dedicated cart," and "ion bombardment treatment."

We received an inquiry from a company in Tochigi Prefecture that specializes in resin molding, asking, "Could we request a comparison of titanium nitride coating and titanium aluminum nitride coating?" They mentioned that among the resin materials they currently handle, there are some that contain fillers such as glass fibers, which are very hard and cause wear on the internal parts during molding, leading to difficulties. When performing resin molding, it is common to use materials known as polypropylene or polycarbonate, but by mixing in glass fibers, the resin becomes even harder. Therefore, when hardness is required for the product, materials with fillers are used. *For more detailed information about the case, please refer to the related links.

We received an inquiry from a company in Saitama Prefecture that manufactures molds, requesting a titanium nitride coating on aluminum molds to improve release properties during resin molding. They use a method called vacuum forming, where a plastic sheet is first heated with a heater to soften it. The sheet is then set into the mold, and air is evacuated from between the product and the mold through holes in the mold. At this time, a device called a vacuum pump is used. As the vacuum pump removes the air, a vacuum is created between the product and the mold, causing them to adhere closely. After that, the product is cooled to solidify the plastic, the vacuum is released, and the product is removed from the mold. *For more details about this case, please refer to the related links. For further inquiries, feel free to contact us.

We received an inquiry from a company in the Tohoku region that manufactures medical devices, asking us to "extend the lifespan of forceps by applying a TiN film coating to the tips of the forceps." Currently, they are using stainless steel in its raw state without any coating, but when the cutting edge deteriorates, the product becomes unusable. To maintain the sharpness, we proposed a TiN film coating that increases surface hardness and reduces friction coefficient. There is a process where a hole about 1mm in diameter is made on the side of a medical catheter tube using the tips of the forceps. It is said that human blood vessels are approximately 25mm near the heart, about 5mm in the arm, and around 0.2mm in small arteries. Therefore, medical catheters are differentiated by size and material depending on the area of use. *For more detailed information about the case, please refer to the related link.

We received an inquiry from a resin processing company in Ibaraki Prefecture, asking, "We would like to make heat-resistant PVC material non-fogging. Could you provide a good coating for this?" At our company, we explained about water-repellent and hydrophilic films based on our accumulated thin film expertise. Water-repellent films have the effect of repelling water and are commonly used in car windshields. In contrast, hydrophilic films have the effect of allowing water to spread. We conducted various simple experiments using acrylic materials to investigate what type of coating would be suitable for the customer. The customer expressed that they would like the coating to remain non-fogging for about six months and requested that the product be processed as a single piece as much as possible, with dimensions of 1000mm x 1000mm. Therefore, durability and size became the key issues in this case. Our equipment can handle metal films up to 1000mm x 1000mm, but for functional films, the limit is about 300mm x 300mm, making it impossible to apply them in this case. As a result, we decided to consider methods that do not use coating equipment. *For more details on the case, you can view them through the related link. Please feel free to contact us for more information.*

We received an inquiry from the School of Dentistry at Tohoku University asking, "Could you apply a TiN film coating on a special Ti substrate without leaving any attachment marks on both sides?" With the know-how we have cultivated, we can manufacture jigs that leave minimal attachment marks. We created a dummy of the actual product size and developed a dedicated jig for prototyping. When it comes to TiN film coating, as well as other coatings, it is necessary to have attachment areas for setting up the device during the coating process. Since the coating film generally does not adhere to the attachment areas, achieving a complete coating on the entire surface of the finished product becomes difficult. Therefore, we ask our customers to clarify which parts are most important to them, and we explore solutions before proceeding with prototyping. *For more detailed information about the case, please refer to the related links. For further inquiries, feel free to contact us.

We received an inquiry from a company in Fukui City, Fukui Prefecture, that develops and manufactures fiber opening devices, stating, "We want to extend the lifespan of the cutting blades used in the fiber opening device for FRP (fiber-reinforced plastic)." Currently, we are using commercially available cutting blades as they are, and to confirm their effectiveness, we have decided to conduct a trial of TiN film coating. Fukui Prefecture has a long-standing textile industry, and it ranks among the top in Japan for shipment value in the textile field, including silk double-weave fabrics and polyester long-fiber fabrics. FRP refers to composite materials that improve strength by incorporating glass fibers or carbon fibers into plastic. Due to its main raw material being plastic, it is inexpensive and lightweight, and in addition to its durability, it is also used in the automotive industry. *Details of the case can be viewed through the related link. For more information, please feel free to contact us.

We received an inquiry from a resin molding manufacturer in Tochigi Prefecture asking, "Could you apply a TiN coating to a screw shaft for an injection molding machine that is about 1500mm long?" Our company has a large HCD device capable of film formation up to 2500mm, and we specialize in long items, so we conducted a trial. The screw shaft is a crucial component of the injection molding machine, used to feed the resin. In injection molding machines, plastic products are mainly manufactured, with typical examples including plastic lenses, optical discs, and medical devices. These products are made by melting resin materials (such as PET and PP) and pouring them into molds using the screw shaft. After that, the molds are cooled to shape the resin material into the product form, and finally, the molds are removed to complete the product. *For more details on this case, please refer to the related link. For further inquiries, feel free to contact us.

We received an inquiry from a company engaged in resin molding for containers, asking if there is a film that has good resin release properties and is moderately hard. The film currently in use has release properties, but it contains hard pearlescent materials, which aggressively attack the substrate, causing the film to fail, leading to difficulties. To ensure the strength of the containers, it seems that some products have pearlescent materials mixed into them, but this also causes significant damage to the equipment, increasing the need for surface coating. When the resin release properties deteriorate, defects occur, so we prioritized coating for resin release properties over hardness. However, we proposed TiN coating treatment as it is expected to possess both functions and resolve the customer's concerns. *For detailed case information, please refer to the related links.

We received an inquiry from Tokyo Metropolitan University in Hachioji City regarding their desire to sputter aluminum onto silicon wafer substrates and perform anodic oxidation treatment. They are struggling because the adhesion and characteristics do not meet the required standards. They would like to confirm what changes occur by depositing a TiN film as the initial layer, but since this is a prototype-only project, other companies have declined, and they are having difficulty finding a company that can perform the deposition. It was mentioned that research on thin film electrode layers is being conducted at the university. In cases where a TiN film coating is applied to silicon wafer substrates, there are often instances where it peels off during tape tests, indicating a significant problem with adhesion. Therefore, we proposed performing a binder coat on the initial layer film to improve adhesion before applying the TiN film treatment. *For more details about the case, please refer to the related links. For further inquiries, please feel free to contact us.*

We received an inquiry from a company related to vacuum equipment located in Chuo Ward, Tokyo, asking if we could collaborate on product development. Originally, we were engaged in the sale of components and equipment for vacuum deposition machines used for film formation, but we resonated with their passion to "utilize vacuum technology to promote more accessible products!" As a result, we decided to pursue joint product development with the aim of acquiring new customers. In particular, they showed great interest in TiN film coating, which has a gold appearance and adds a sense of luxury, as well as its higher corrosion resistance and longevity compared to stainless steel. This led us to process TiN film on everyday products. We started prototyping with common tableware such as spoons and forks. We found that the jigs used for attaching to the spoons and forks tended to leave marks, so we considered improvements to prevent jig marks from remaining. *For more detailed information about this case, please refer to the related links. Feel free to contact us for further inquiries.*

The company that manufactures and sells stainless steel is facing issues with printing defects caused by foreign substances sticking to card-type resin products during printing. They also seem to be struggling with appearance quality, delivery times, and work-in-progress. We proposed a "TiN coating" after confirming each situation. By applying a TiN film coating that improves resin release properties (releaseability) to the surface of the stainless steel plates used in printing machines, we can reduce the sticking of resin and expect a decrease in the defect rate. [Case Study] ■ Company: Stainless steel manufacturing and sales ■ Issues: Reducing defect rates, appearance quality, delivery times, and work-in-progress ■ Improvement Proposal - TiN film coating to enhance resin release properties on the surface of stainless steel plates - Conducted cleaning tests considering various types of dirt, including water-soluble and insoluble contaminants - For wiping streaks, ion bombardment treatment was performed in a vacuum device - Due to the large equipment, productivity is high, and TiN film coating can be done for small lots in about two weeks, allowing for management without work-in-progress *Details of the case study can be viewed through the related links. For more information, please feel free to contact us.

The characteristics of TiN film are that titanium (Ti) reacts with nitrogen (N) to improve hardness, enhance wear resistance, and reduce the coefficient of friction on the surface, which also improves sliding and peeling properties. Our company performs TiN coating using a vacuum deposition machine, and therefore it is necessary to remove contaminants, oils, and moisture from the product surface. The processing steps include removing discoloration and foreign substances with a special polishing cloth, removing oils with organic solvents, removing moisture with alcohols, and wiping the surface dry with cloths before inputting. This prevents a decrease in adhesion, degradation of properties due to impurity gases, and surface discoloration. 【Processing Steps】 ■ Removal of discoloration with a special polishing cloth ■ Removal of foreign substances ■ Removal of oils with organic solvents ■ Removal of moisture with alcohols ■ Surface dry wiping with cloths ■ Input *For more details, please refer to the related links or feel free to contact us.
