▼ What is a "Refresh Battery"? It is a regeneration service for used battery packs. The secondary batteries (cells) inside the battery pack are replaced with new ones, while the case, control circuit, and other components are reused as they are. ▼ Four Benefits of Refresh Batteries 【 Price 】 The price is about half that of a new one, greatly contributing to cost reduction! *The capacity may increase compared to before the refresh. 【 Environment 】 It is eco-friendly and contributes significantly to CO2 reduction! For every 1g of battery pack (plastic part), it can contribute to a reduction of 6g of CO2. *Old cells (batteries) are recycled by specialized companies. 【 Attachment 】 You can continue to use your beloved, older devices for a long time! Even battery packs that have been discontinued by the original manufacturer can be continued to be used by refreshing them. 【 Peace of Mind 】 All cells (batteries) are quality inspected! The refresh work is carried out by skilled workers in domestic factories, and a three-month warranty is provided after delivery. For more details, please refer to the catalog or feel free to contact us.

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 a winding example for coils with protrusions!】■□■□■ 【Features】 The usual coil frame has a flat winding section with no obstacles, but in this case, there are four protrusions on the winding section, as shown in the photo. 【Challenges】 Due to the occurrence of wire floating at each protrusion, we repeatedly changed the winding method to minimize the floating of the wire. As a result of these repeated efforts, we successfully achieved the winding shown in the photo. 【Usage Example】 It is used as a coil for internal inspection machines at a certain electrical manufacturer. At MDS, we can support coil production by leveraging our expertise and technology in terminal processing for relay coils. *For more details, please contact us or download the catalog.

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 a case study on reinforcement of relay coil terminal wires!】■□■□■ 【Features】 Due to the tendency for extremely fine wires (less than 0.03 mm) to break near the terminals, we perform twisting wire terminal processing. By using twisted wires (3, 5, and 7 strands), we have reduced the incidence of breakage near the terminals. 【Challenges Faced】 Because of the multi-axis winding (16 axes), the twisted wires (3, 5, and 7 strands) resulted in thicker wire diameters, requiring careful attention to ensure even winding of the insulation. With a terminal length of 1.5 mm, we twisted the insulation 5 times, and during soldering, we struggled with the unsoldered finish around the base, which required one complete round. 【Usage Examples】 The twisted wire type is used for coils ranging from 24V to 100V. They are mainly used in power-related control applications. 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.

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.

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.

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 a case study of terminal processing for relay coils!】■□■□■ 【Features】 Two-winding latching coil Two types of copper wire are wound, and terminal processing is performed by connecting two copper wires to the same terminal with three terminals. 【Challenges】 Typically, copper wire is cut using the edge of the terminal, but since two wires need to be connected, the edge of the terminal becomes difficult to use for the second wire, making it prone to whiskers. Therefore, we wound the first copper wire with a coarse pitch spiral and connected the second wire in between. In multi-axis automatic winding, variations occur on each axis, causing overlaps in the connected wires, so we repeatedly adjusted the fixtures and programs. 【Usage example】 Used in lighting relay coils At MDS, we leverage our terminal processing technology and know-how for relay coils to support coil production. *For more details, please contact us or download the catalog.

Due to dimensional restrictions after soldering, we perform the stripping in a spiral manner to suppress swelling after soldering. 【Challenges】 In multi-axis automatic winding, variations occur on each axis, leading to overlapping of the stripped wire, requiring precise jig adjustments. 【Usage Example】 Used in relay coils.
