"Free Sample Presentation Campaign" This time, we are offering free samples of our LED-equipped boards that have been completely sealed using hot melt molding to customers who request them. Please feel free to take a look at the actual product. "What is Hot Melt Molding?" It is a groundbreaking sealing method that provides excellent waterproofing, dustproofing, and insulation by injecting thermoplastic adhesive around electronic components. Since it solidifies within seconds in the mold, sealing is completed in a shorter time compared to traditional two-component potting and BMC molding. Additionally, the hot melt we handle is primarily made from natural fatty acids derived from grains, making it highly sustainable. Customers who wish to receive a sample, please do not hesitate to contact us.

The technology "Hot Melt Molding," which is expanding its adoption for waterproofing, dustproofing, and insulation protection of various electrical components, rapidly solidifies thermoplastic hot melt adhesives within molds, completing sealing in a short time of just a few dozen seconds. Compared to traditional urethane potting and epoxy potting, this technology allows for sealing to be completed in an ultra-short time, leading to alternatives aimed at process improvement and cost reduction. Additionally, because it involves mold forming, it offers high freedom of shape, receiving high praise for miniaturization and lightweighting of components. Our company, Matsumoto Processing, has been involved in the protection of many electrical components, including automotive electrical components, as a pioneer of this technology alongside our customers. We can achieve material selection, specification consideration, prototype shape design, mold manufacturing, and prototyping in a short time. Customers interested in this technology are encouraged to feel free to contact us.

In recent years, the importance of thermal management has been increasing to efficiently dissipate heat in components that are miniaturized or require high current. Therefore, Matsumoto Processing is proposing a two-component curing thermal conductive filler. This material can be automatically applied at room temperature using a dispenser, can be easily compressed to any desired thickness, and flexibly conforms to the unevenness of components. It reacts and cures within a few hours after application, and after curing, it becomes a solid material with flexibility, eliminating concerns about pump-out during long-term use. This product is expanding its applications in filling gaps between heat-generating components and heat sinks, as well as between heat-generating substrates and aluminum cases.

In November 2018, we added a new lineup to the popular MK series hot melt molding machines. The molding size of the conventional MK series hot melt molding machines was generally limited to about the size of a business card. However, we received many requests from customers wanting to mold larger substrates and improve production efficiency with multiple parts. In response, we developed the newly announced <MK700H>. Like the MK600, it retains a compact machine size while expanding the projection area of the molds to 300×200mm. Additionally, it maintains the feature that the power source consists only of electricity and compressed air, while increasing the clamping force to 7.5 tons, which is 7.5 times that of the MK600. As a result, the MK700H enables the molding of large substrates over the size of four business cards. A working model is currently on display at our lab in Fuji City, Shizuoka Prefecture. We invite you to come and see it.

In recent years, IoT has been gaining attention, and our technology "hot melt molding" is being used for the waterproofing and dustproofing of modules installed outdoors. If you are considering waterproofing and dustproofing for your modules, please feel free to consult with us.

To prevent expensive measuring instruments from moving around and getting damaged inside the box, we have created storage pads for securing them. Additionally, we have also created a space for storing accessories (fuses and screwdrivers).

In January 2015, our company released a new model of hot melt molding machine: the MK600. In the case of conventional low-cost molding machines, it was necessary to manually tighten the mold, but this machine achieves automatic mold clamping while still being low-cost. Additionally, the discharge mechanism employs a reliable dual gear pump. Please refer to the product catalog for detailed specifications.

Hot melt molding. It is a waterproofing technique for electronic devices such as circuit boards and sensors that has gained attention in recent years. The reason for this attention is undoubtedly the simplicity of the process. While two-component potting requires three steps—mixing, injection, and curing—which can take several hours to complete the product, hot melt molding completes the product in just one step and in a matter of seconds. (For more details on hot melt molding, please visit our company website.) We have received numerous inquiries for LED displays and LED lighting applications in the past, but many cases have not led to product development due to the yellowish tint of PA-based hot melts. The material we are introducing this time has significantly improved transparency compared to conventional products. Customers who would like samples are welcome to contact us.
