Prevent short circuits in electronic devices caused by contact between metal parts! With a printing method that allows for mass production, insulation can be applied only where needed.
In order to achieve high-precision insulation of metal parts for miniaturized electronic devices, we established a self-developed screen printing method in 2012. By printing UV-curable ink only in the necessary areas, we can form a resin insulation film on metal parts. Since we can print continuously in large quantities, we can process precise insulation films for electronic device covers and packages at low cost and with short lead times. Please make use of this technology for the high functionality of fine and precise components, such as those in mobile communication devices and semiconductors. 【Features】 ■ Screen printing technology using self-developed UV-curable ink (Please inform us of the model number of the ink you will be using) ■ Ideal for cases where insulation is only needed in specific areas, such as metal covers ■ Capable of processing tens of millions of units per month for low-voltage components like communication devices ■ Printing accuracy can be adjusted at the micron level ■ Thickness of the printed film (approximate): up to 20μ ■ Unique full inspection system using cameras Identifies printing defects (misalignment, smudging) → Marking → Sorting ■ Only good products are shipped (defective prints are removed by pressing only in those areas before shipping) ■ Printing environment (dust prevention): within a clean booth

basic information
**Materials that can be accommodated (hoops)** Stainless steel (SUS), iron-based materials (Fe/KOV), copper-based materials (Cu), etc. **Shapes of materials that can be accommodated** Hoop materials (reel-to-reel method) *For sheet materials, please consult separately.* **Usage image (process)** 1. Pressing (cutting) Drill guide holes, etc., in the material (metal hoop material) and supply it to us. (If requested, we can handle the pressing process.) ↓ 2. Base plating (ensuring adhesion of the resin film) Hoop plating (nickel) → Ensures rust prevention of the target item and adhesion of the printed film. (Our group company can handle plating.) ↓ 3. Screen printing Continuously print UV-curable ink to form a resin film. Deliver the printed items in a reel-to-reel format. ↓ 4. Pressing (cutting/bending) Forming as required for parts. (If requested, we can handle the pressing process.) **Inspection items, etc.** ■ Adhesion tests (peeling and scratching tests) ■ Film thickness and hardness tests, etc. ■ All areas with printing defects are saved as camera images. *For more details, please feel free to contact us.*

Company information
The slogan is "Challenge the Impossible." We are a technology development-oriented company that broadly develops unique surface treatment technologies to meet the special needs required for essential low-voltage components (related to electricity, electronics, and semiconductors), high-voltage components (such as high-voltage connectors), and insulating components. Additionally, we have established a support system that incorporates functional surface treatments, which we have cultivated since our founding, as our core technology, along with processes such as pressing, heat treatment, painting, and assembly. We will continue to deliver consistent Yuden-sha brand technologies and products to the world. *We support online business meetings.
