Understanding Molded Rubber Products
Molded rubber products are created through various processes that shape uncured rubber into desired forms. These processes include compression molding and injection molding, as described by hongjusilicone.com. The final product is a durable, versatile component used across numerous industries. The choice of molding technique depends on factors like product complexity, production volume, and desired precision.
Technical Features of Molded Rubber Products
The performance of a molded rubber product hinges on several technical characteristics. These include hardness, tensile strength, elongation, tear resistance, and compression set. Understanding these properties is crucial for selecting the right product for a specific application. The following table compares these key features:
| Feature | Description | Importance |
|---|---|---|
| Hardness (Shore A) | Measures resistance to indentation. Ranges from 0 to 100, higher is harder. | Affects durability and resistance to wear. |
| Tensile Strength | Maximum stress a material can withstand before breaking. | Indicates the material’s strength and ability to resist stretching forces. |
| Elongation | Percentage increase in length before breaking. | Measures flexibility and elasticity. |
| Tear Resistance | Force required to propagate a tear in the material. | Crucial for applications subjected to impact or abrasion. |
| Compression Set | Permanent deformation after being compressed for a specific time. | Indicates the material’s ability to return to its original shape after compression. |
Types of Molded Rubber Products
The versatility of molded rubber is reflected in its diverse product forms. These include O-rings, gaskets, grommets, bushings, and many more specialized parts. Each type offers unique properties suitable for specific applications. www.shidarubber.com, for example, is a leading manufacturer of many of these. The following table highlights some common types:
