Molded Rubber Components
We take pride in the technical excellence and versatility of our custom rubber molding capabilities. Our business supports:
- Wide range of thermoset polymers, from the basic EPDM to a highly engineered Fluoroelastomers
- Broad span of annual volumes – low, mid, and high volume production capabilities
- Large variety of applications – simple grommet applications, tightly-tolerance, and precision-molded diaphragms, complex hoses, highly-cosmetic medical applications, and much more
- Significant diversity in part size, from small parts that fit on a fingertip, to large parts that need to be carried with two hands
- Multiple molding technologies – compression molded, transfer molded, and high speed, injection molded product
- Insert molding capabilities – we can overmold rubber onto metallic (stainless or carbon steel, aluminum, etc.) and non-metallic structural components such as fiberglass and glass-filled thermoplastics
- Value-added operations, including deflashing, grinding, kitting, assembly, testing, along with Kanban and inventory programs

Part or Product Size
Precision mechanical components range in size from 1 gram to over 30 pounds. In-house production utilizes presses from 8″ square to 24″ square, and our GlocalSource presses have capabilities up to 60″ square.
Multiple size presses are used to meet your program requirements. Molding technologies include:
- Injection — Strip form material is drawn into the press, heated, and then forced into the mold cavity under controlled pressure, temperature, and injection speeds.
- Ram-Injection — Billets of material are manually loaded each heat, or press cycle, into a secondary hydraulic ram, which then forces the rubber into a closed mold cavity.
- Transfer — A “preform” of material is placed between the top mold plate and an additional ram plate. This method uses the closing press to transfer rubber into the cavity. A block of material is placed in a “pot” and then, with a punch, forced into the mold cavity.
- Compression — A pre-sized, mass of rubber is set directly into the mold cavity and then squeezed into shape as the mold plates close around it.
Annual Volume Sold
Low, mid, and high volume production capabilities. Some of our customers only require small production runs, while other customers require weekly releases and a supporting KanBan program to keep them in supply. The systems and methodologies we’ve learned from larger, more structured companies can be applied to benefit customers across the board.
