products Description
A Magnetic Yoke is one of the core components of relays and is widely used in electrical equipment. With its efficient magnetic field guiding performance, it helps relays achieve precise control of current switching. As the magnetic structure of relays, A Relay Yoke Neck is responsible for connecting the electromagnetic coil and the iron core, transmitting electromagnetic energy to drive the precise closing and opening of contacts.
The Yoke Mount Kit for Relay we provide is made of high-quality metal materials and advanced processing technology, featuring excellent electromagnetic performance and mechanical strength. It is widely applicable to various electrical and automatic control systems.
Product Advantages
High Magnetic Permeability & Low Loss
The Relay Magnetic Frame adopts soft magnetic materials with high saturation magnetic flux density, combined with an optimized magnetic circuit structure. This results in lower magnetic reluctance and faster magnetic conduction, making the relay more sensitive to actuation and quicker to release. It greatly reduces coil power consumption and heat generation, while improving energy efficiency and service life of the finished product.
Stable Dimensional Accuracy
The Electromagnetic Relay Frame undergoes precision stamping and shaping. Key positioning dimensions, perpendicularity and flatness are highly consistent, enabling direct integration into customers' fully automatic assembly lines. This reduces defects such as jamming, misalignment and weak magnetism, boosting overall production efficiency.
High Mechanical Strength
The Relay Iron Frame also serves as a reinforcing structure for the bobbin, featuring excellent rigidity and toughness. It resists bending, loosening and fracture under high-vibration environments including automotive, industrial control and rail transit, ensuring long‑term reliability of the relay.
Uniform Heat Treatment
The Relay Magnetic Armature Yoke is processed through controlled-atmosphere heat treatment, delivering stable and controllable magnetic permeability and coercivity. Performance variation within the same batch is minimal, which helps unify the parameters of finished relays and enhance the quality stability of export products.
Production Process
Pre-Commissioning & Trial Stamping Optimization of Molds
Before each batch of Relay Core Yoke Assembly production, full-parameter pre-commissioning is carried out on the stamping molds to accurately calibrate blanking clearance, bending angle and positioning accuracy. Small-batch trial stamping is adopted to inspect product dimensions and forming status. For minor deviations detected during trial stamping, mold parameters are optimized in real time to avoid dimensional deviation, edge burrs and other defects in mass production, so as to control production consistency from the source.
In-line Shaping & Cleaning in Intermediate Processes
An in-line shaping and cleaning process is added between stamping and heat treatment. Precise shaping tooling is used to conduct secondary fine adjustment on key parts of the Magnetic Circuit Yoke for Relay, eliminating minor deformation generated during stamping. Meanwhile, an environment-friendly cleaning process is applied to remove oil contamination, iron scraps and oxide dust from the product surface, preventing impurities from affecting subsequent heat treatment effect and surface coating adhesion.
Aging Stabilization Treatment of Finished Products
After surface treatment, aging stabilization treatment is performed on the Relay Stator Yoke. Through constant-temperature standing and gradient cooling processes, internal residual stress of the product is released to stabilize the magnetic properties and dimensional accuracy of the material. This effectively avoids deformation and permeability fluctuation caused by stress release during long-term storage, transportation, or assembly, ensuring long-term stability of the relay magnetic circuit.
Advantages of the Dust-Free Stamping Workshop
Fully Enclosed Dust-Free Environment Control: The workshop adopts a positive-pressure dust-free design and is equipped with a multi-stage air filtration system, which effectively controls the concentration of dust, metal chips and impurities. It prevents impurities from being embedded into the material surface during stamping, and fundamentally eliminates issues such as insufficient coating adhesion and abnormal magnetic circuit conduction of the Stamped Yoke for Relay caused by surface contamination.
Zoned Clean Process Management: The workshop is divided into independent clean areas according to processes including uncoiling, stamping, heat treatment and inspection. Isolation barriers and air shower channels are set between different areas to avoid cross-contamination between processes, ensuring the surface cleanliness of the Metal Frame for Relay Coil throughout the whole process of forming, heat treatment and inspection, and improving product consistency.
Personnel & Material Clean Control: All operators must wear dust-free clothing and dust-free gloves, and pass through an air shower purification before entering the workshop. Materials are transported in sealed packaging, and dedicated cleaning tools are equipped to regularly clean equipment and workstations. This minimizes pollution caused by personnel and materials, guaranteeing the production precision and quality stability of high-end precision Magnetic Yoke.
