Understanding the Technical Features of Custom Molded Gaskets
The performance of a custom molded gasket hinges on several key technical features. These features are influenced by the material selection and the manufacturing process employed. Manufacturers like www.anlintech.com emphasize their in-house mold making capabilities, ensuring precise control over product tolerances.
| Feature | Description | Importance |
|---|---|---|
| Material | The type of rubber or silicone used (EPDM, silicone, nitrile, etc.). www.shidarubber.com offers a variety. | Determines chemical resistance, temperature range, durability, and cost. |
| Hardness (Shore A) | Measures the material’s resistance to indentation. | Affects the gasket’s ability to seal under pressure and its resilience. |
| Tensile Strength | The maximum stress a material can withstand before breaking. | Indicates the gasket’s resistance to tearing and stretching. |
| Elongation | The percentage increase in length a material can sustain before breaking. | Shows the gasket’s ability to conform to uneven surfaces. |
| Compression Set | The permanent deformation after being compressed for a specific time. | Crucial for maintaining a reliable seal over time. |
| Tear Strength | The force required to propagate a tear in the material. | Indicates the gasket’s resistance to damage from accidental punctures or cuts. |
| Ozone Resistance | The material’s ability to resist degradation from ozone in the atmosphere. | Essential for outdoor applications. |
| Bond Strength | For rubber-to-metal bonded gaskets, this measures the strength of the bond. | Ensures the integrity of the gasket in applications requiring a strong bond between materials. |
Types of Custom Molded Gaskets
Numerous types of custom molded gaskets cater to various applications and requirements. Companies such as www.evergreenrubber.com highlight their diverse product portfolio, including gaskets and seals for various applications.
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Compression Molded | Formed by applying heat and pressure to uncured rubber in a mold. | Relatively low tooling cost, fast lead times, suitable for large parts. | Limited precision and complexity; not ideal for tight tolerances. |
| Injection Molded | Molded using high pressure to inject heated rubber into a mold cavity. | High precision, consistent quality, suitable for complex designs, readily automated. | High initial investment cost; more suitable for high-volume production. |
| Rubber-to-Metal Bonded | Combine rubber and metal for enhanced strength, durability, and heat resistance. | Superior strength and heat resistance. | More complex manufacturing process; higher cost. |
| Silicone Gaskets | Made from silicone rubber, offering excellent flexibility, temperature resistance, and chemical resistance. | Flexible, high temperature and chemical resistance. | Potentially higher cost than some rubber materials. |
| EPDM Gaskets | Made from Ethylene Propylene Diene Monomer, known for weather and ozone resistance. | Excellent weather resistance; suitable for outdoor applications. | Less resistant to oils and certain chemicals than other materials. |
| Nitrile Gaskets | Made from Nitrile rubber, offering excellent resistance to oils and fuels. | Good oil and fuel resistance. | Poor resistance to chlorinated hydrocarbons and ketones. |
