New hot melt molding, useful for VA (posted sample)
Outline
With excellent heat resistance, gasoline resistance, oil resistance and moisture resistance and using simple molds, hot melt can be used to protect and waterproof products.
The user can count on case-less use, process reductions, material consumption reductions with inline use, and productivity improvements.
Certain to be useful for cost reductions.

Use・Results
Example 1 Waterproof connector
Current: Rubber plugs are attached to electrical wire terminals and inserted into connectors to provide water-proofness.
Hot melt: Insert the connector with the pre-inserted electrical wire into the mold, inject the hot melt, let cool for 20 to 30 seconds, then remove.
The electrical wire and connector are molded with hot melt to make a waterproof connector.
Advantages
1. Eliminate rubber plugs
2. Reduce size of connector
3. Reduce parts management
Example 2 Thermistor (protect and waterproof contact)
Current: Attach steel tube to contact, inject resin, and heat cure for 30 to 60 minutes.
Hot melt: Insert thermistor into the mold, inject hot melt, after cooling, the protection portion is completed.
Advantages
1. Eliminate steel tube
2. Productivity improved, from 60 minutes to 30 seconds
3. Separate inline and hardening operations can be integrated
Example 3 Sensor (protect and waterproof lead wire contact point)
Current: Make a case for the contact point, inject resin, and heat cure
Hot melt: Insert lead wire contact point into mold, inject hot melt, and after cooling casing and protection are completed together.
Advantages
１． Caseless
２． Improved productivity
