The advantages of rubber-coated iron parts are as follows:
1. Protection: The rubber coating protects the iron part from corrosion, abrasion and impact.
2. Cushioning: It provides cushioning effect when in contact with other objects, reducing the impact force and protecting both the iron part and the contacted equipment or product.
3. Improved grip: The rubber surface offers better grip, making it easier to handle and install.
4. Noise reduction: Can reduce noise generated during operation.
5. Electrical insulation: In some cases, it can provide electrical insulation properties.
