Compounding and Stock Preparation

In House Custom Mill Mixing
Rubber isn’t just a generic, black, elastic material. Rubber is vital to the operations of countless companies and fully integrated into thousands of products and devices worldwide. We can formulate custom compounds designed to deliver specialized performance to meet or exceed your unique requirements that no off-the-shelf product can match. At Ames Rubber Manufacturing, we have custom mill mixing capabilities and an active library of hundreds of in house compounds for oil resistant, non-oil resistant and specialty elastomers ranging from Neoprene^® to Nitrile and Silicone to Viton^®.

A Network of Custom Compounders
Beyond that, we have also developed a network of specialized rubber compounders that we utilize each with experienced rubber chemists representing vast knowledge in virtually every elastomeric specialty to ensure that your rubber molding needs are met or exceeded.

Molding Capabilities

Use our  Ames Rubber Molding Guide to help you determine the best molding process for your specific application, or just contact us at your convenience and we will work with you throughout the production process, from concept to completion. Our molding capabilities include:

De-flashing & Trimming

Once a rubber part has been molded, in most cases it must be de-flashed.

Ames Rubber Manufacturing has invested regularly in the equipment and technology related to insuring a clean, finished part for our customers.

Cryogenic De-flashing
The most versatile and effective way to de-flash rubber products is through liquid nitrogen tumbling and shot blasting. The rubber parts are placed inside a barrel or basket and liquid nitrogen is used to chill the parts so that the flash becomes brittle, but the part does not crack. Once chilled, the machines tumble the parts around on themselves and fire ceramic media at the parts to encourage all the flash to break off. Depending on the material being run, we can set temperature controls and size and velocity of the media to ensure optimal de-flash with minimal breakage. These setting are saved for each and every molded part that we run.

Mechanical and Hand Trim
In addition to the automated de-flashing equipment, Ames Rubber Manufacturing utilizes specialty grinding and Dremel® tools and other hand tools for parts that would not optimally be cryogenically de-flashed such as rubber to metal parts, and large parts or parts with heavy flash from older molds. With limited employee turnover, our trim and finishing department employees are some of the most experienced and well trained in the industry.

Documentation for Quality Assurance
Once quality acceptance standards are established for a particular part, Ames Rubber Manufacturing uses digital photography to document what is acceptable and what is not. By using prints and pictures with notations with our production travelers, we insure uniform acceptance criteria across shifts and personnel as well as repeatability from year to year.
