We Don't Sell Rubber. We Provide Solutions.
Rubber Processibility Analyzer testing developemental compounds
Provide us with your requirements such as product life, resilience, taste/odor, tensile strength, spring rate and damping. Let us provide the value added product development solutions. CRC maintains a complete design testing laboratory as well as prototyping facility as a vital part of its operation. Over the past four decades, CRC has created an extensive elastomer physical property data library and extensive dynamic test result database. Our core competence is as rubber compounder and molder.

Let our Product Development Engineers Design Your Parts
Best overall part cost and longest part life are achieved by good engineering, chemistry, and design experimentation and testing using statistical techniques and statistically based problem solving tools. Parts used dynamically for sealing, vibration control, etc., require complex compounding and chemistry. Additionally, with our chemistry expertise, we can provide reverse engineering solutions to loosely defined problems.

Corry Rubber offers the finest in contract design services. Our engineers have over 100 years combined design experience. We offer design and material selection assistance to all of our customers. We also offer performance contracts for design work only. CRC is typically involved in the simultaneous engineering and design of 5 to 10 new components at any one time.

Model it First
CRC utilizes Finite Element Analysis (FEA) to aid in the development of products using existing technology and sequential molding technology. FEA provides the ability to model both the manufacturing process and the finished part on a computer. Using this technique, we can understand strains in parts and design longer lasting products or tune our process to minimize waste and maximize output. CRC may be the only company of its size supporting customer engineering development efforts using FEA.

One such product modeled with the aid of this engineering tool was a “track pad” assembly in which there were over 100,000 nodes in the model. This was an extremely complex rubber to metal bonded assembly which was modeled using non-linear FEA. We have also analyzed existing customer products to provide feedback to eliminate premature failures and to improve the design of their products.

CRC utilizes AutoCAD Mechanical Desktop for mold and part design. Hundreds of molds, parts and dies have been designed in-house for a multitude of applications. FILLCALC, the computer aided injection molding modeling program, allows CRC to model the injection molding of elastomers. By doing this, CRC is able to design mold runners and gates on the computer, rather than by trial and error. We are also able to try different processing conditions using the computer to maximize our output without using production equipment. This reduces the amount of time necessary to debug molds and consequently reduces cost to the customer.

Implemented for our automotive customers, CRC utilizes Failure Mode and Effect Analysis (FMEA). FMEA is a means of numerically evaluating the likelihood of a problem in the manufacturing process causing a defective part; the likelihood of that part getting shipped and the severity of the problem that would occur if that part found its way to a vehicle or other finished good. FMEA helps us identify which steps in the manufacturing process should be watched most closely.

Test it Correctly.
CRC’s extensive lab also boasts state of the art instruments to test products for a variety of properties, such as aging, tensile strength, elongation, resistance to temperature, moisture, atmospheric ozone, oils, solvents, spring rates, and damping. We have actually determined the necessary material constants for FEA in our laboratory. Not many companies of any size can say that. These physical testing capabilities, combined with statistical analysis, can determine how well a new product will hold up in its actual environmental situation.

The Mixing Advantage
Corry Rubber is one of the few elastomer manufacturers that mixes and tests its own elastomer batches on premise. After testing, elastomer is then preformed, extruded, injection molded, compression molded or transfer molded into high quality elastomeric products.

High quality and a reasonable production tooling cost are items that we strive to maintain. We control the designs of tools, acting as general contractor to determining which parts of the tool go where. We find this to be much more expeditious and cost advantageous for our customers.

Our Super-Flexible Supply Advangage
CRC can provide stocking programs and/or work with Kanban programs. We provide back-up supply which the customer pays for as they use it, providing a strong competitive advantage to our customers.
