Overview

At KC Seals, we excel in CNC machining, specifically tailored to the unique demands of rubber and plastic materials. Our advanced capabilities encompass both CNC turning and CNC milling, enabling us to produce complex sealing components with unparalleled precision and efficiency. In addition, our CNC machines and tooling are specifically procured and designed to handle a variety of materials, including PTFE, PEEK, Polyimides, various elastomers, and more, ensuring that we meet the diverse needs of our engineering clients.

Choosing the right plastic or rubber material for CNC machining is critical, as each material has unique properties that influence its machinability and suitability for specific applications. For example, polycarbonate is prized for its high clarity and impact resistance, making it ideal for transparent applications, while nylon is valued for its strength and toughness, suitable for load-bearing components. At KC Seals, we leverage our deep understanding of these materials to select the best options for your project, ensuring optimal performance and longevity of the final product.

Our expertise in CNC machining extends beyond just material selection. We understand the intricacies involved in machining plastics and rubber, which are generally less rigid than metals and can deform under excessive heat and pressure. Our skilled machinists employ specialized tooling and techniques to manage these challenges effectively, using precise machining parameters to achieve tight tolerances and minimize material deformation. This precision is particularly vital in industries such as aerospace, medical devices, and microelectronics, where exact specifications are critical.

Additionally, KC Seals is equipped to handle complex geometries that might be difficult or impossible to achieve with other manufacturing methods. Our CNC machining allows for the creation of intricate designs with high repeatability and consistency, which is essential for both prototyping and large-scale production of custom parts. Our rapid turnaround times, often as quick as one day, cater to the urgent needs of mechanical engineers who require precision and reliability in their components.

Partnering with KC Seals means you are working with a team that combines extensive experience, advanced technology, and a deep understanding of material properties to deliver the best CNC machined rubber and plastic components in the industry. Trust us to provide the precision, efficiency, and expertise that your projects demand.
