Finite element analysis (FEA) is utilized when applicable. Our seal and tool design team has combined experience of over 100 years.

Tool & Die Design and Mfg Capabilities

Seals Eastern has a captive tool and die manufacturing facility equipped  with state-of-the-art CNC, mill, and drilling operations. Electronic drawings are used to generate programmed tool-paths which are  downloaded to our numerically controlled equipment. This facility produces high tolerance tooling that gives Seals Eastern the ability to manufacture the highest quality precision molded rubber products.

Precision Molding Capabilities

Seals Eastern utilizes:

• rubber injection molding,
• compression molding, and
• liquid injection molding (LIM).

Rubber Compound Design & Mixing Capabilities

Seals Eastern has a captive rubber mixing facility capable of producing statistically consistent rubber compounds. Seals Eastern has experience formulating and mixing nearly all synthetic polymers currently available in the market. 

Our Materials Development Center offers instrumentation to monitor the quality of each batch of rubber mixed. Important material properties are verified using a computer integrated MDR2000 and Instron Tensilometer. These same instruments, in addition to others, facilitate material development and product improvement for Seals Eastern customers.

Failure Analysis Capabilities

Our Engineering Team has 24 x 7 access to our Materials Development Center to analyze field failures and in some instances, re-create the failure environment. This service is an integral part of our customer support program.
