We would like to introduce a case of partial sealing of electronic components conducted at a certain industrial equipment manufacturer. We achieved weight reduction and successfully reduced the amount of resin used. Furthermore, sealing is possible for a maximum size (actual value) of 300mm × 250mm. This is recommended for automotive accessory manufacturers and industrial equipment manufacturers where weight reduction and durability are required. 【Case Study】 - Achieved weight reduction - Successfully reduced resin usage - One-time molding *For more details, please refer to the PDF document or feel free to contact us.

Hot melt molding is a noteworthy new technology that allows for the injection of low-melting-point thermoplastic resin into molds under low pressure, enabling the insert molding of various electronic components while adding diverse and excellent protective performance. Compared to conventional methods, it reduces damage to delicate electronic components while improving productivity and allowing for lightweight and compact designs. Additionally, since the external shape can be directly molded, improvements in design aesthetics can also be expected. In our "Hot Melt Molding," we can reduce the number of components by 7 points. Please feel free to contact us when you need assistance.

Nakatani's "Hot Melt Molding" significantly improves productivity compared to potting molding. With injection molding alone, not only is the curing time shorter, allowing for reduced production time, but the need for curing equipment is also eliminated, which reduces production space. Additionally, the thin-walled molding does not require exterior, thus reducing material usage and enabling overall cost reduction. Furthermore, being a solvent-free one-component system, it is harmless, odorless, and environmentally friendly, making it an ecological and economical new technology. 【Features】 ■ Molding temperature: 180℃ to 250℃ ■ Molding pressure: 3 to 50 kgf/cm² ■ Reduces damage to components ■ Thin-walled molding and no exterior required for material reduction ■ Saves both time and space *For more details, please refer to the PDF document or feel free to contact us.
