Terminal processing for relay coils! Terminal processing of stranded copper wire at the base of terminals measuring 7 to 9 mm.
MDS: In the electronic components processing division, we handle electronic components that support environmentally friendly products. Utilizing our cultivated precision processing technology, we produce various coils used in high-precision communication and office automation equipment (small-batch production of many varieties). ■□■□■【Introducing examples of terminal processing for relay coils!】■□■□■ 【Features】 We perform terminal processing on copper wire ends that are curled at the base of terminals measuring 7 to 9 mm. Normally, soldering is done, but since solder cannot adhere to the terminal tip, we apply heat while holding the copper wire with a chip to melt the plating of the terminal and carry out terminal processing. 【Challenges】 If pressed too hard, the copper wire breaks, and if pressed too lightly, it causes poor contact. We conducted repeated tests to set the conditions. 【Usage examples】 These are used in relay coils and are also utilized in the Shinkansen N700 series. At MDS, we leverage our relay coil terminal processing technology and know-how to support coil production. *For more details, please contact us or download the catalog.
Winding examples for the jig core! This is a coil and jig core type without a karage terminal.
MDS: In the electronic components processing division, we handle electronic components that support environmentally friendly products. Utilizing our cultivated precision processing technology, we produce various coils used in high-precision communication and office automation equipment (small lot production of many varieties). ■□■□■【Introducing examples of coils without color terminals and jig cores!】■□■□■ 【Features】 This is a type of coil and jig core without color terminals. The starting wire is temporarily colored on the jig core before winding. After winding is completed, a temporary color is applied to the jig core as well. 【Challenges】 The temporary colored wire is cut to extract the coil, but the length of the lead wire from the coil is designed and manufactured to be within specifications, so there is no need for further adjustments later. 【Usage Example】 It is used in lighting coils. At MDS, we leverage our winding technology and know-how for jig cores to support coil production. *For more details, please contact us or download the catalog.

Establishment of the winding device program! We can undertake the development of prototype coils with higher performance!
For a long time, wires have supported the evolution of electricity and electronic components with their round shape. However, around the year 2000, square wires were commercialized as a type of wire that could further enhance the performance of the coil section. "Square Wire Coils" can exhibit the required characteristics for coils by utilizing square wires, which offer benefits such as increased occupancy rate, advantages of the skin effect, improved heat dissipation, space-saving, and increased power. Applications range from electronics and electrical products to automotive industry equipment, aerospace industry equipment, and space industry equipment. 【Features】 ■ Improved occupancy rate ■ Advantages of the skin effect ■ Increased power of the coil ■ Enhanced heat dissipation ■ Space-saving *For more details, please refer to the PDF materials or feel free to contact us.
