Custom Rubber Molding Services

With a successful performance history as a highly respectable rubber manufacturer, Pierce-Roberts Rubber Company has been a long-time supplier of top-quality, custom molded products. We are well-equipped to handle a broad variety of rubber materials, ranging from elastomers and silicone to neoprene, Buna N, and EPDM. Upholding precision tolerances of (±) .005 inches, we specialize in three of the most common rubber molding operations: compression, injection molding, and transfer. And, we can custom mold rubber materials measuring up to thirty six inches in length, width, and height.

Known for its extreme durability and resilience, rubber performs well in applications requiring sturdy functioning within high pressure environments or during extreme distortion conditions. And, with the ability to manufacture high-performance products constructed from this durable material, we have happily served the needs of multiple industries, including aerospace, electronics, and medical.

At Pierce-Roberts, we are determined to provide clients with superior products that meet high industry standards. Even after manufacturing is complete, we store all of our finished work in designated areas at specified temperatures, ensuring our products are delivered to our clients without distortions. We also invite you to contact Pierce-Roberts to inquire after any of our additional service options, which include, but are not limited to, rubber to metal bonding, anodizing, and rapid prototyping. From aircraft and robotic components to custom seals and insulators, we offer superior custom rubber molding products and services.
