Step-by-Step Coil Production Process
Preparing Raw Materials
The first step is getting the right materials. High-quality copper wire and insulation are needed for reliable coils. Using local suppliers is important for safety and accuracy. American suppliers follow strict rules, which lowers mistakes and delays.
To track materials, manufacturers use heat numbers. These are special codes that show where the metal came from. Mill Test Reports also give details for quality checks. Choose suppliers with strong quality programs. This ensures the coils work well in latching relays and control systems.
Tip: Check the copper wire's size and surface before using it. These affect how well the coil works in relays.
Pin Inserting
Our fully automatic coil production line has a highly integrated process flow, in which the pin insertion process is the primary link. Its professionalism and precision are directly related to the production efficiency of the entire line and the reliability of the product. Pin insertion refers to the vertical pressing of high-precision plated metal pins into the preset holes of the bobbin with a tolerance of 0.01mm.
This process builds the core channel for electromagnetic field conduction, so that the number of turns of copper wire wound later can be accurately controlled to ensure that the inductance of the coil is stable and meets the standard. At the same time, the pin is also a welding carrier. Its verticality error of less than 1° can ensure that the solder joints are full and uniform during automatic soldering, reducing the loop impedance.
Winding the Coil
Winding is a key step in making coils. Copper wire is wrapped around a core to make electromagnetic coils. Accuracy is very important here. Machines must control speed and tension to avoid wire problems. A good tension system keeps the wire steady and prevents breaks.
Modern machines let you set different options for each coil type. This is helpful for latching relays, where even layers are needed. Speed control makes sure every layer is the same, helping the coil work well in relays.
Machines control tension to keep the wire strong.
Speed control ensures even layers for better coils.
Programmable settings help make different coil designs.
Quality checks ensure the final coil meets standards.
Note: Advanced winding machines reduce mistakes and make production faster.
Soldering
Soldering involves joining pins and wire ends together to create a secure electrical connection. This critical step requires precise techniques using high-quality solder with the right melting point and conductivity. Our automated soldering machines ensure consistent soldering results, precisely controlling temperature, solder flow, and application time to create a secure, reliable joint. Apply rosin flux before soldering.
Proper soldering ensures the integrity of the circuit, allowing the coil to work effectively in relay systems, which is critical for consistent performance in high-risk applications such as automotive, telecommunications, and industrial automation.
Final Testing and Packaging
The final stage of coil production – testing and packaging – is critical to ensure that only top-quality coils make it to market. These steps are the last line of defense, carefully verifying the integrity of the coil before it is sent to the relay.
During the testing phase, the core electrical and physical properties of the coil are rigorously checked. For coils used in latching relays, specialized tests are also performed to evaluate their ability to generate and maintain a stable magnetic field. This comprehensive evaluation includes measuring the coil's resistance to ensure optimal conductivity, checking the insulation to prevent leakage, and rigorously testing its overall functionality under a variety of simulated conditions. Using advanced automated testing equipment, these evaluations are performed with amazing speed and precision, leaving no room for unqualified coils.
After successfully passing the rigorous testing test, the coils are orderly loaded into the tray. The robotic arm precisely grabs the coils and neatly arranges them in a special tray with millimeter-level accuracy, ensuring that each coil is evenly spaced and oriented. The standardized loading process not only facilitates subsequent efficient handling and circulation, but also maximizes the utilization of storage space, laying the foundation for rapid product delivery.
