Dual-structure core for reducing roll tendency and shaft diameter conversion (Lotus Core)

Dual-structure core for reducing roll tendency and shaft diameter conversion (Lotus Core)

Keep the existing shaft (for 3 inches) and increase the outer diameter to 6 inches/8 inches! Reduce the curling tendency of films and labels during the process!

The "Lotus Core" can reduce the curling of films and labels! It is mainly used for winding separator films and in the winding processes of tack labels and tack seals. It is also effective for winding semi-finished products before they are cut into sheets. With existing equipment, it is possible to increase the winding diameter (6 inches/8 inches). It addresses cost issues related to equipment modifications and dummy winding of products. The more expensive the film, the greater the expected improvement! It prevents the deterioration of film performance caused by "curling" and "strong winding pressure" that occur during the winding process.

SS Placoare

SS Placoare

Significantly reduces the step marks at the beginning of the film roll!

This is a core with a cushioning function applied to the surface of a plastic core, designed to reduce "step marks" at the beginning of film winding. ■ A special stress-relief layer absorbs the steps caused by the thickness of the film. ■ The transfer of step marks to the film is minimized. ■ There is a proven reduction of up to 90% in step loss (effects may vary depending on the customer). The higher the unit price per square meter of the film, the more likely it is to see improvement effects!

Metal roll pallet with FRP core

Metal roll pallet with FRP core

Packaging materials that solve problems related to the packaging and transportation of heavy films weighing over 1 ton.

We will introduce examples of packaging materials that solve problems related to the packaging and transportation of large films weighing over 1 ton. For film rolls such as polarizers, which weigh around 1 ton each, a combination of metal roll pallets and FRP cores is fundamental. Many products are headed to China and South Korea. The design is built to withstand the G-forces experienced at sea and when traveling on poorly maintained roads. In terms of cost, it is reasonable and not as expensive as aluminum. The roundness of the FRP core is less than 0.05. The pallets can be folded and reused.

[Production Example] Laminated Motor Core (φ110×35×0.2mm)

In-mold laminated core using sequentially delivered press molds.

This is a laminated motor core (φ110×35×0.2mm). The material is 50A300, and it is primarily used for power transmission devices. This laminated motor core is assembled using a progressive die that performs lamination within the mold. A precision of 0.05mm is required for perpendicularity, parallelism, coaxiality, and roundness, necessitating advanced precision mold manufacturing technology, which is why we were consulted by the company that specializes in burr-free precision pressing. We are capable of sourcing a variety of materials, not only common iron and SUS but also from amorphous products to special alloys, and we provide one-stop solutions from prototype processing of custom motor cores and resolvers to mass production. Additionally, based on the data accumulated in our unique production management system, we offer products to our customers at reasonable prices.

[Production Example] Motor Core (φ110×0.2mm)

[Production Example] Motor Core (φ110×0.2mm)

Motor core by wire cutting

This is a motor core (φ110×0.2mm). The material is 35A440, and it is primarily used as a component for power transmission devices. For this core, we processed it by sandwiching multiple stacked blank materials with thicker iron to reduce vibration during processing caused by the injection of cutting fluid. The processing steps were carried out in the order of "outer circumference rough machining → hole rough machining → outer circumference finishing → hole finishing." Additionally, for motor cores of this shape, having only one start hole on the outer circumference would cause the workpiece to move during processing, so we created two or more start holes for machining. Our company is capable of sourcing a wide range of materials, from general iron and SUS to amorphous products and special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. Therefore, we also propose cost reduction from the design stage based on past processing data. If you are facing challenges with the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.

[Production Example] Stator Core (φ300×0.25mm)

[Production Example] Stator Core (φ300×0.25mm)

Motor core made by press processing.

This is a stator core (φ300×0.25mm). The material is 25A, and it is a product used for power transmission devices. This stator core is quite large, with a size of φ3000mm, and using wire cutting would incur enormous costs in terms of both time and money. Therefore, our company manufactured it by creating a prototype mold and performing punching through press processing. While the size is large, the precision is similar to that of other parts, making it a product that requires high processing and assembly precision of the press mold components. However, at our custom shim manufacturing center, we were able to produce it with a beautiful finish and almost no burrs through burr-free precision press processing using molds with good assembly precision. Our company is capable of sourcing a variety of materials, not limited to general iron and SUS, but also including amorphous products and special alloys, providing one-stop solutions from prototype processing to mass production of custom motor cores and stator cores. Additionally, based on our unique data, we offer products to customers at reasonable prices. If you are having trouble with the design and manufacturing of custom motor cores and stator cores, please feel free to contact our custom shim manufacturing center.

Equipment Abnormality Wireless Monitoring System

Equipment Abnormality Wireless Monitoring System

The "abnormal equipment alarm signal monitoring system" is configured solely by setting the radio equipment.

This is a system that reports abnormal occurrences to the management location when an abnormal signal is emitted from factory equipment. The abnormal signals from the factory equipment are input into the UMDI-41AXS and transmitted via 920MHz wireless communication to the UMIO-88AXS at the management location. The setup software for the UMIO-88AXS and UMDI-41AXS can be downloaded for free from our company website. - Easy setup by connecting the PC to the device via cable. - Communication range of 1 km in outdoor line of sight. - Communication using repeaters is possible. - Repeater settings can also be configured with the same software. Signal collection for the documentation is done via 1-to-N communication. Example: 1-to-N (1 point dispersed mode) setting. In the case of one master unit, UMIO-88AXS, and one slave unit, UMDI-41AXS (1 point input), a maximum of 8 slave units can be configured for an abnormal signal monitoring system. A demo unit is also available for your use.

DapTechnology's FireGate PHY Layer Core

DapTechnology's FireGate PHY Layer Core

FireGate is an IP core that complies with IEEE-1394b and supports all AS5643 requirements.

Advantages of implementing a complete 1394 I/O interface using FPGA Standalone solution: By combining PHY IP with link layer IP, it is possible to create smaller products. Additional components can be added to create a system-on-chip (SoC) solution. Flexible number of ports: Commercially available PHY chips have a fixed number of ports, which is often excessive for small peripherals. On the other hand, host adapters are likely to benefit from three or more ports, and hubs can have even more ports. In the case of PHY based on FPGA technology, users can customize the number of ports as needed. Optional debugging and testing features: Optionally, debugging and testing features such as BERT (Bit Error Rate Testing) can be included. Field upgradable: The FPGA used is field-upgradable, allowing new features and bug fixes to be added even when the device is already in the field. Cost-effective ASICs: Once the design is complete, the IP solution provides a very cost-effective way to spin custom ASICs.
