Suitable for sealing LED lighting, optical sensors, etc.! Colorless transparent hot melt.
Low Pressure Molding, Hot Melt Molding, Waterproof and Dustproof, Encapsulation Molding
"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.
A waterproof insert molding method that directly injects thermoplastic adhesives into electronic components! We have received many inquiries and requests in the past for applications such as LED lighting fixtures, decorative lighting, and optical sensors, but conventional materials had a strong yellow tint and issues with light transmittance. This time, we are introducing a material that not only supports low-pressure molding sealing of electronic components like traditional hot melts but also excels in light transmittance. <Expected products for use> - LED lighting equipment - Display devices using LEDs, etc. - Light-based sensors such as photo sensors and fiber sensors

basic information
●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.

Company information
Our company provides comprehensive support for the introduction of hot melt molding methods, from initial technical discussions and appropriate hot melt selection to prototype production and evaluation, optimal process considerations for mass production, proposals for optimal equipment or the design and manufacturing of dedicated machines (automated systems), hot melt supply and line support. For customers for whom equipment installation poses a barrier to adopting this method, we even offer production contracting at our facility, ensuring support from "start to finish." **Benefits of Hot Melt Molding** - Improved production efficiency and cost reduction through alternative methods to potting - Greater design flexibility due to mold forming, enabling miniaturization and lightweighting of components - Use of sustainable raw materials derived from natural fatty acids We have various molding machines and displays of adopted products available at our prototype lab in Fuji City, Shizuoka Prefecture.
