[Improvement Case] Automatic recording, calculation, and analysis of coil measurement data.

[Improvement Case] Automatic recording, calculation, and analysis of coil measurement data.

Introduction of automatic measurement software! A case where the time to create inspection reports for coils has been significantly reduced.

We would like to introduce a case study on improving quality control operations through the introduction of software that automatically records, calculates, and analyzes coil measurement data. When creating inspection reports manually, we received feedback from customers about errors and difficulty in reading. By implementing the automatic measurement software "QC Pro," the time required to create inspection reports for coils has been significantly reduced, leading to improvements in quality control operations. [Case Summary] ■ Benefits - Improvement in quality control operations - Easier management with traceability through search functions - Provision of accurate inspection reports to customers ■ Challenges - Regular system inspections are necessary *For more details, please refer to the PDF document or feel free to contact us.

[Improvement Case] Quality Stabilization through Consistent Production System (Mold Coil)

[Improvement Case] Quality Stabilization through Consistent Production System (Mold Coil)

Introduction of cases where the clarification of responsibility during trouble occurrence and the speed of investigation and countermeasures have improved.

We would like to introduce a case where we achieved stabilization of quality by establishing a consistent production system at our company for products that were previously distributed among multiple companies for each process. By modifying various parts based on a general-purpose winding machine and adjusting the takt balance of each process, we consolidated the molding, winding, assembly, and overmolding processes into a single line. This has significantly improved productivity while controlling work-in-progress inventory. 【Case Overview】 ■Challenges - Distribution among multiple companies for each process ■Benefits - Stability in processes and quality - Clarification of responsibility during trouble occurrences, and faster investigation and countermeasures - Shortened delivery times *For more details, please refer to the PDF document or feel free to contact us.

One-stop from bobbin to resin mold.

One-stop from bobbin to resin mold.

From prototype and small lot to mass production! Introducing our one-stop service in the blog.

The bobbin-wound coils require not only precision and strength of the winding but also the accuracy and durability of the bobbin, which are factors that influence productivity. PRONEC has introduced Japanese-made resin molding machines at its factory in Thailand, where local engineers and operators are engaged in the production of resin parts, including bobbins, with Japanese quality. Additionally, it is possible to perform resin molding in the later stages to enhance waterproofing and seismic resistance. *For more details, you can view the related links on the blog. For further information, please refer to the PDF materials or feel free to contact us.*

From jig manufacturing to the positioning of line outputs, even for complex three-dimensional shapes.

From jig manufacturing to the positioning of line outputs, even for complex three-dimensional shapes.

Production technology capable of stabilizing even complex shapes! Introducing our coils in a blog format.

Our factory in Thailand is equipped not only with winding machines but also with resin molding machines for bobbins and molds. We have introduced winding machines manufactured in-house and Japanese-made resin molding machines, and our production line is operated by experienced engineers and skilled operators. As a result, PRONEC can manufacture high-quality and reliable bobbin-wound coils, molded coils, and leaded coils for circuit board assembly in a one-stop service. *For more details, you can view the related links on our blog. Please refer to the PDF materials or feel free to contact us for more information.

Design that anticipates mass production from prototype to small lot.

Design that anticipates mass production from prototype to small lot.

We would like to introduce the development that incorporates feedback from our production technology!

PRONEC is equipped with scalability that can accommodate everything from prototypes to small lots and mass production. If you need coils for mass production prototypes, please feel free to contact us. In the case of small lots, there are initial costs for jig production and line assembly, so the costs are higher compared to mass production. However, we have manufacturing facilities that can meet various requirements such as the performance and shape your company desires, and we have many experienced engineers and operators on staff. *You can view detailed content on the blog through the related links.

[Improvement Case] Work efficiency improvement up to the winding end terminal cutting process.

[Improvement Case] Work efficiency improvement up to the winding end terminal cutting process.

Systematizing the product discharge! Introducing a case that significantly improved work efficiency.

We would like to introduce a case study on improving work efficiency up to the terminal cutting process after winding. Typically, in the case of hollow coils, to cut the specified terminal length after winding, the operator uses a jig to perform the subsequent process. By systematizing the movement of the air nipper to the specified coil terminal and cutting it to the designated terminal length, we significantly improved work efficiency up to the product discharge. 【Case Overview】 ■ Effects - Increased production capacity - Prevention of variability due to manual work - Reduction of man-hours ■ Challenges - Limited to specific product shapes *For more details, please refer to the PDF document or feel free to contact us.

What is coil winding?

What is coil winding?

An automatic winding machine that manufactures coils with high speed and high precision! Explanation of winding types included.

Winding is a key design point that involves factors such as the material and thickness of the wire, the number of turns, the winding direction, and the shape. By appropriately setting these elements, it is possible to achieve performance suited to the intended purpose. Winding can be done manually, but in modern times, automatic winding machines are used for mass production. Automatic winding machines can manufacture coils at high speed and with high precision, playing an important role in the manufacturing industry. *For more detailed information, please refer to the related links. For further details, please check the PDF materials or feel free to contact us.*

Explanation document "Secrets of Tension Management that Affect the Quality of Coil Winding"

Explanation document "Secrets of Tension Management that Affect the Quality of Coil Winding"

This explains the basic concepts and management methods regarding the tension of coil winding. It also introduces various benefits that can be obtained by maintaining appropriate tension.

Tension management of coil winding is an important factor that influences coil quality and product performance. By maintaining appropriate tension, various benefits can be expected, including: ◎ Winding Alignment The layers of winding can be uniformly aligned, minimizing gaps and overlaps. ◎ Stability of Electrical Characteristics Electrical characteristics such as inductance and resistance values become stable, improving product performance. ◎ Assurance of Mechanical Strength With the winding securely fixed, durability against vibrations and shocks is enhanced. ◎ Efficiency of the Manufacturing Process Winding operations proceed smoothly, reducing the rate of defective products and improving overall manufacturing efficiency. Therefore, our company, which specializes in coil production under appropriate management, is currently offering materials that clearly explain the basic concepts of tension, management methods, and types of tension devices based on our extensive knowledge. *For more detailed information, please refer to the download button below.*
