Customization to your Specifications

Compression Molding

A cost-effective method for producing durable rubber parts with consistent results. Pre-heated rubber is placed into a heated mold cavity, and pressure is applied to shape and cure the material. This process is ideal for:

✔ High-strength, long-lasting components
✔ Simple to moderately complex part designs
✔ Cost-effective small and large production runs

Transfer Molding

A process that combines the benefits of compression molding with an added step where pre-heated rubber is forced into the mold via a plunger. This technique allows for:

✔ Faster cycle times for increased efficiency
✔ Greater detail and tighter tolerances
✔ More intricate designs, including over-molding and inserts

Benefits of Our Rubber Vibration Dampeners

Custom formulations to meet ASTM and Mil-Spec standards
Versatile production capabilities for small prototypes and large-volume runs
Excellent durability and material integrity
Precision engineering for complex designs and tight tolerances
Streamlined processes for cost-effective manufacturing

No matter the complexity of your project, Southern Michigan Rubber provides precision-molded rubber components engineered for durability and performance. Contact us today to discuss your requirements.
