"Complete sealing of electronic components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding is gaining attention for the waterproof sealing of electronic components.

●What is Hot Melt Molding? It is a technology that demonstrates excellent sealing performance by directly injecting hot melt adhesive into electronic components. □Advantages of Adoption 1. Reduction in Processing Time Hot melt molding completes one molding cycle in about 10 seconds to several tens of seconds. Unlike potting, there is no need for curing time. 2. Reduction in the Number of Parts Unlike potting, hot melt molding does not require a case. This allows for a reduction in the number of parts and production processes. 3. Reduction in the Amount of Resin Used Hot melt molding can be shaped with minimal thickness that conforms to the inserted components.

Complete sealing of electrical components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation! Hot melt molding is gaining attention for the waterproof sealing of electrical components.

Examples of Contract Processing Customer 1: Coil Manufacturer They want to seal large coils for incorporation into equipment using hot melt, but with a production volume of about 10 units per month, they cannot expect to recover the investment even if they introduce a molding machine... → Contract processing with Matsumoto. Customer 2: Electronics Manufacturer They want to seal parts of HEMS-related devices with hot melt. They have a plan that spans a decade for widespread adoption, but for the first five years, the production numbers will be very low, and they want to refrain from capital investment. If production numbers increase steadily after five years, they would like to introduce equipment at that time. → Contract production with Matsumoto. Additionally, Matsumoto, which also handles equipment, provides peace of mind when it comes to equipment introduction. Customer 3: Home Appliance Manufacturer The model life is short, around one year, and they are unsure if the next model will also require hot melt sealing, so they cannot make capital investments. → Contract production with Matsumoto. Customer 4: Lighting Equipment Manufacturer There are significant fluctuations in production quantities, making it impossible to set up processes in-house. → Contract production with Matsumoto.

Reduction in Processing Time Hot melt molding completes one molding cycle in about 10 seconds to several tens of seconds. There is no need for curing time like in potting. 2. Reduction in Number of Parts Hot melt molding eliminates the need for a case. This allows for a reduction in the number of parts and production man-hours. 3. Miniaturization and Weight Reduction Hot melt molding can be shaped with minimal wall thickness along the insert components. This is expected to reduce the amount of resin used, leading to miniaturization and weight reduction. Matsumoto Processing will respond quickly to the selection of suitable hot melts, modeling of molding shapes, analysis, mold production, and prototyping after understanding the reliability required for your products. For customers wishing to introduce hot melt sealing processes in-house, we provide comprehensive support including the production and sale of molding machines and molds, development of molding parameters, process startup assistance, and supply of hot melts. For customers who wish to outsource the hot melt sealing process, we offer contract molding services.

●What is Hot Melt Molding? It is a technology that demonstrates excellent sealing performance by directly injection molding hot melt adhesive onto electronic components. □Advantages of Adoption 1. Reduction in Processing Time Hot melt molding completes one molding cycle in about 10 seconds to several tens of seconds. There is no need for post-heating curing or waiting time until hardening, as is required in potting. 2. Reduction in the Number of Parts In hot melt molding, the molded part can incorporate functions such as casing and housing, allowing for the omission of cases that are necessary in potting. This enables a reduction in the number of parts and production processes. 3. Reduction in the Amount of Resin Used Hot melt molding can be shaped to conform to the parts being insert molded. This leads to a reduction in the amount of resin used, as well as miniaturization and weight reduction.
