Washers

CB Frost is a well-established UK manufacturer of sponge, foam and rubber washers.

Located in Nechells, Birmingham, we convert a wide range of sheet materials into washers using a range of different manufacturing techniques depending on customer requirements.

With our in-house capabilities, we can produce washers via die cutting, kiss cutting and water jet cutting. In order to meet high volume demands, we have invested in precision machinery, including our ultra-high-speed cutting machine capable of running up to 100 strokes per minute, ensuring the highest levels of quality.

Depending on your needs, we can convert closed cell, open cell, semi-closed cell sponge, foam, or solid rubbers into washers for a range of sealing and vibration absorption purposes. With our extensive experience of manufacturing and supplying washers, our sales team is ready to provide expert guidance on selecting the right washer material for your specific project requirements.

CB Frost has established a long-standing relationship with Rogers Corporation, a global leader in engineered materials. As as an approved supplier and converter of Rogers Corporation products, we supply their complete range of EN45545-2 approved materials, which provide durability, efficiency and performance across a vast spectrum of applications within industries including Rail, Automotive, EV/HEV, HVAC, Aerospace, MoD, Construction, Agriculture, Lighting, Enclosures, and more.

Once we have manufactured washers to customers’ specifications, we pack them securely in suitable packaging materials, labelling them to meet customer needs. We offer additional packaging options such as barcoding, individual polybags, and cardboard packaging inserts upon customer request. For the confidence of our customers, we also offer a door-to-door washer delivery service, making sure that orders arrive safely and securely in the expected time.

Our Washer Manufacturing Capabilities

We can also apply pressure sensitive adhesive tape to one or both faces of foam, sponge and rubber washers. We supply a variety of different acrylic and synthetic tapes with easy-peel release liners that can be removed with ease, exposing the adhesive backing to the washer. This allows for washers to be secured to their intended surface for a strong bond. Our sales team are on hand to recommend the most suitable laminate to ensure the most effective adhesion and greatest longevity under the conditions washers will be exposed to.

To increase the efficiency of our washer manufacturing operations and improve lead times, we have invested in our own tooling room, which allows us to manufacture all die cutting formes for washers in house, preventing the need to wait for tools from a third party. We can create custom dies for washers of all sizes, to suit a wide range of materials.

We have the capabilities to produce small and large orders of washers in a lead time of 7-10 days. Should our customers require a faster turnaround, we will aim to improve production times where possible.
