Kingsmagnet’s rubber magnetic strips are flexible, elastic, and twistable magnets made by combining rubber with magnetic materials. The production process involves several key steps:

1. Raw Material Preparation

• Magnetic Powder Selection:
  Depending on the desired performance, suitable magnetic powders such as barium ferrite or strontium ferrite are selected. Key properties like particle size, purity, and magnetic strength directly affect the final product.

• Rubber Base Selection:
  Rubber materials such as neoprene, nitrile rubber, or EPDM are chosen as the carrier matrix. Each type of rubber offers specific advantages—like oil resistance, aging resistance, or flexibility—based on the end-use environment.

• Additive Preparation:
  Additives such as curing agents, antioxidants, and fillers are prepared to enhance the rubber's processability and improve the strip’s physical and chemical stability.

---

2. Mixing

• Equipment Setup:
  Open mills or internal mixers are used. Open mills mix materials using two rotating rollers, while internal mixers blend materials in a closed chamber using rotors.

• Mixing Process:
  First, the rubber is plasticized to improve its processability. Then, magnetic powder and additives are added in a specific order and timing. Key factors like temperature, time, and mixing strength are carefully controlled to ensure uniform blending and product quality.

---

3. Forming

• Extrusion:
  The mixed compound is pushed through an extruder to create continuous rubber magnetic strips with a desired cross-section. This method offers high efficiency for long-length production.

• Calendering:
  The compound is flattened into sheets using calendering rollers, then cut or stamped into shape. Calendering produces smooth, evenly thick strips, ideal for thinner products.

• Compression Molding:
  The compound is placed in a mold and formed under heat and pressure. This method is suited for complex shapes with high dimensional accuracy, often used in small-batch or precision applications.

---

4. Curing (Vulcanization)

• Purpose:
  Vulcanization causes the rubber molecules to crosslink, forming a stable three-dimensional network. This enhances strength, hardness, elasticity, and resistance to aging.

• Process:
  The curing method (e.g., hot air, steam, or flat-plate vulcanization) and parameters (temperature, time, pressure) are selected based on the rubber type and product needs.

---

5. Magnetization

• Principle:
  A strong magnetic field is applied to align the magnetic domains in the powder, giving the strip its magnetic properties.

• Methods:
  Depending on the product’s shape and magnetic requirements, techniques such as pulse or direct current magnetization are used, with precise control of parameters.

---

6. Post-Processing and Inspection

 

• Finishing:
  The magnetic strips may be trimmed, cleaned, or coated with protective layers to enhance appearance and durability.

• Quality Inspection:
  Finished products undergo thorough testing, including:

  • Magnetic properties (remanence, coercivity, intrinsic coercivity)

  • Physical properties (hardness, tensile strength, elongation)

  • Visual and dimensional checks
    Only qualified products are approved for market release.

Introduction

In modern fuel-powered vehicles, the electrical system plays a crucial role, and the wiring harness is the "blood vessels" and "nerves" of the entire electrical system. It is responsible for transmitting power, signals and data to ensure the normal operation of various components such as the engine, lights, instruments and safety systems. So, what exactly are the wiring harnesses in a fuel-powered car? What are their respective functions?

 

 1. What is an automotive wiring harness?

A Wiring Harness for automobiles is an integrated system composed of multiple wires, cables, connectors, terminals, protective sleeves (such as tapes, bellows), etc. It is designed and assembled in accordance with the electrical layout of the vehicle to ensure that power, signals and data can be transmitted efficiently and stably.

Due to the complex internal environment of automobiles (high temperature, vibration, humidity, etc.), the wiring harness must meet the following requirements:

• High-temperature resistant (The engine compartment can reach over 120℃)
• Anti-vibration (preventing fracture caused by long-term vibration)
• Waterproof and dustproof (especially in the chassis and engine compartment)
• Electromagnetic shielding (to avoid signal interference

 

2. Classification of main wiring harnesses in fuel vehicles

The wiring harnesses of fuel vehicles are usually classified by functional areas and mainly include the following categories:

(1)Engine Harness

ESG Bearing is an expert of rolling mill bearings. The working conditions for steel mill bearings are demanding as they will face dust, steel particles, water, heat, high speed and high temperature, almost the toughest conditions compared to other industry.

Bearing with higher hardness will be more wear-resistant, but it will easily crack. Thus the bearing's working life will be reduced.

How to  avoid this problem, most bearing manufacturers do not dare to make the bearings too hard. Their hardness is around 58~60 HRC. ESG Bearing has the advanced heat treatment technology. The tenacity of the bearing is improved by 30% compared with ordinary bearings. The hardness of the bearing is also improved by 2 HRC, reaching about 60~61 HRC. Thus the bearing is more wear-resistant and won’t easily crack out, it has a much longer working life.

Rolling mill bearings have to carry higher load and speed. They need to be more resistant to weariness and impact. Material takes an important role of the bearing performance. ESG Bearing selects the best mold casting steel, which contains less gas and particles, with the following features to improve the ESG bearing performance.

Better Grain Structure:Mold casting often results in a finer grain structure in the steel, which can contribute to improved mechanical properties such as strength, toughness, and wear resistance.

Higher Precision: Mold casting can provide higher precision in achieving intricate bearing designs and dimensions, especially for rolling mill applications.

Less Defects: Mold casting can lead to fewer internal defects like porosity and inclusions due to the controlled solidification process.

Better Surface Finish: Mold casting generally offers better surface finish and dimensional accuracy, which can be crucial for reducing friction and ensuring proper fitting in precision applications.
