Rubber Molding Capabilities
The most popular molding process, compression molding uses pressure and heat to mold the rubber into the shape required. Compression molding is a good manufacturing choice for large parts, parts that do not require tight tolerances, and low production quantities. It requires inexpensive tooling, but is a labor-intensive process with longer loading and process times than other molding methods.
Compression molding press capabilities for our compression line range from 12” x 12” on the low end, up to and including 85” x 108” on the high end, with various press sizes in between.
Rubber transfer molding uses a process similar to compression molding, but has a transfer system on the top of the mold that feeds the rubber into multiple mold cavities when the press is closed. This allows for more efficient processing – tool and material loading times are reduced. It is used for large parts, parts that do not require tight tolerances, and higher production runs than compression molding.
Minor Rubber’s transfer molding press capabilities for our compression line range from 12” x 12” on the low end, up to and including 85” x 108” on the high end, with various press sizes in between.
With injection molding, rubber is pre-heated before being injected into the mold. Since it is pre-heated, the rubber flows more readily into the mold, allowing for higher cure temperatures, shortening the curing cycle. Injection molding presses provide tight clamping, which results in little or no flash. Parts manufactured using injection molding may not require additional finishing. The process is used for high production runs and parts that require tighter tolerances.
Our injection press capabilities range from 24” x 24” up to 48” x 72”, with tonnage (clamping force) of 100 to 500 tons.
Our facilities are fully equipped with state-of-the-art equipment and managed using the latest technologies. With production facilities located in the United States, we have the flexibility and capacity to manufacture your parts efficiently and economically, while meeting the highest quality standards.
Rubber extruding services for a variety of industries. Our rubber extrusions include profiles and tubing, cut washers, and gaskets. With our state-of-the-art manufacturing facility, we provide extruded rubber manufacutring for a range of products, including:
- Vulcanized spliced gaskets
- Gaskets with molded or injection molded corners
- Simple and complex shaped seals, washers and gaskets
- Strips, cord and seals in long lengths on reels or coils, or as cut lengths
- Tubing and profiles in long lengths on reels or coils, or as cut lengths
- Holes, notches, and special cut-outs can be fabricated into our extruded products
Tubing and Cord sizes range from 1/32” I.D. up to 7” O.D., and wall thicknesses as thin as .040”.
Profile shapes can range from .125” square up to and including 8” square. Wall thicknesses on extruded profiles, like tubing, can be as thin as .040”, but will depend on the shape of the cross section.
