How to Select Material in Rubber Molding Processes

When manufacturing high-performance components, selecting the right material is a key step in the rubber molding process. The material affects the component’s durability and determines its ability to withstand harsh conditions, such as extreme temperatures or UV exposure. At Clark Rubber and Plastic, we help manufacturers develop custom molded solutions that meet specific functional requirements. Here is how to select the right material in the rubber molding process:

Material Selection

In rubber molding, the material you choose often affects how the product performs, including its response to heat, chemical exposure, and pressure. Each of these factors influences the lifespan of the final component. Different elastomers are engineered to provide distinct mechanical and chemical properties, which makes some materials better suited for specific environments.

A rubber gasket used in an automotive engine usually needs to tolerate high temperatures. It also needs to withstand oil and fuels without degrading. A sealing component for solar applications may need to endure years of outdoor weathering and maintain its flexibility despite constant UV exposure.

Materials used in household appliances must balance elasticity with resistance to cleaning agents and perform effectively over repeated cycles of moisture exposure. Analyzing the conditions in which a part will function helps verify that the selected material will not face premature wear. Other factors that influence material choice include:

• Evaluating compression set resistance so seals recover their shape after repeated stress
• Assessing abrasion resistance for parts that will experience friction or constant contact with moving surfaces
• Checking electrical insulation properties for components used in power equipment
• Reviewing temperature thresholds to determine if hard plastics will crack if temperatures drop below freezing

Performance Requirements

Each industry has distinct performance challenges. Selecting the right elastomer often starts with understanding these demands and how they affect long-term performance. In the automotive field, engine mounts and hoses must withstand intense vibration. They can be consistently exposed to fuels and high temperatures, which create a harsh operating environment for components.

Appliance manufacturers often need materials that will flex to prevent cracking when in contact with cleaning chemicals. These materials typically need to maintain their structure after multiple heating cycles, especially in dishwashers and clothes dryers. Weighing these performance requirements against the properties of different elastomers allows engineers to align a material’s capabilities with certain conditions. This helps reduce the likelihood of failure and enables components to function effectively throughout the product’s lifespan. At Clark Rubber and Plastic, we provide custom elastomer solutions and materials engineered to meet the standards of various industries.
