Die Cutting Machine & Size Change Parts for Envelope Converting


Best Cutting Die is a leading supplier of aftermarket parts for most every envelope converting machine. This includes various size change and machine parts. BEST size change, replacement machine parts and other accessories provide significantly reduced prices in comparison to other vendors. Our size change parts also reduce inventory costs and minimize machine downtime, making more timely delivery dates achievable.

BEST offers all in-house capabilities including vacuum heat treating, computer-controlled machining centers and state-of-the-art testing/inspection equipment. This allows for total control in the quality of our size change parts, service and turnaround times. Finished parts are subject to extensive quality control review where material composition, hardness, fit and function are validated.

Machine Parts

BEST doesn’t just supply size change parts. We also offer a growing list of envelope machine parts for most W+D and SMITHE envelope folding machines, with the ability to manufacture most any part required. If we don’t currently manufacture a needed part, our timely reverse-engineering process typically results in significantly reduced prices and shortened delivery times in comparison to OEM and other suppliers.
