Description

Technical Field

[0001] This utility model relates to the field of headphone internal structure manufacturing technology, specifically to a dispensing secondary molding and coating device. Background Technology

[0002] In the manufacturing process of bone conduction headphones, titanium wire is a key component. Due to its excellent physical and chemical properties, such as high strength, light weight, and good corrosion resistance, titanium wire is widely used in the structure of bone conduction headphones to ensure durability and comfort. However, the flatness of the titanium wire has a crucial impact on the overall performance and appearance quality of bone conduction headphones.

[0003] However, due to material properties and process limitations, existing solid silicone pre-compression molding and liquid injection molding methods are difficult to completely solve the problem of titanium wire leakage caused by the flatness of the titanium wire when applied to titanium wire coating. Therefore, we propose a dispensing secondary molding coating device to solve the above problems. Utility Model Content
