National Rubber Corporation is a recognized nationwide supplier of die cutting services for a wide variety of industries and applications. We employ a wide range of rubber materials including EPDM, Viton®, Nitrile, and Silicone, to name only a few. We provide die cut product quantities from prototypes and short runs to large production runs. At National Rubber, we take pride in our ability to produce accurate die cut parts that are guaranteed to meet customer specifications and perform perfectly within the intended application.

Precision die cutting is a process of converting sheets or rolls of non-metallic materials into die cut parts with speed, accuracy and uniformity. Die cutting is fast, consistent and cost-effective for parts that range from miniature washers to large gaskets. Accurate die cut parts applications include seals, gaskets, bumper pads, barriers, packing, vibration dampers, dust seals and diaphragms, among others. Die cutting is a very versatile process capable of holding tolerances as tight as ±.02". Die cut parts have a high degree of uniformity, even across high volumes.

Our team of engineers can help our customers with material, tolerance and process information to help choose the right material to customer specification.

As an ISO certified manufacturer, our customers can be assured that their die cut parts are held to stringent quality standards. In-house testing and inspection capabilities include a range of material testing and dimensional inspection in accordance with customer specifications.

National Rubber can die cut parts up to 48" wide and 72" in length. For larger parts, we can "dove tail" or interlock parts.

We offer you following reliable services:
Custom Mixing
Using variable speed, 50 horsepower mixers, we can mix even the most demanding engineered compounds. Each mixer is followed by three high horsepower, variable speed control mills that can provide continues batch blending. The result is total consistency from batch to batch.

Consistency is also assured by our state-of-the-art control systems. These systems supply an extensive array of data that we can use to solve problems and enhance the performance of your compounds. In addition, drilled front rolls and precision temperature control capabilities enable us to handle silicone and other heat sensitive compounds.
Custom Extrusion
We have a sophisticated control drive that allows us to maintain extremely close tolerances to RMA classifications. We have the engineering capability and skill to extrude profiles of complex shapes of prescribed colors & Shore hardness as per the sample / Blue Print sketch provided by the customer. Developimg from Prototype to production of any elastomer is forte at National Rubber Corporation.
