Manufacturing Capabilities

Porvair Sciences has a wealth of knowledge in how to manufacture exceptional porous plastics. Our varied and advanced manufacturing capabilities allow us to support our customers with a variety of different product options.

Vyon® Sheet and Roll

Vyon® sheet and roll materials have been manufactured at our site in the UK for over 50 years to the highest of quality standards. Our rolls and sheets can be manufactured in widths over 1050mm wide to lengths bespoke to our customer requirements. Our standard product range of Vyon® sheets offers 1m x 1m sizes in the majority of our materials. Sheets can also be cut down to size or welded together to meet customer requested sizes.

Vyon® Cut Discs

One of the many conversion techniques we use is our unique rotary cutting process. Using single and multi-impression cutters we can efficiently convert Vyon® porous plastic rolls into discs and washers. Our versatile approach means we can offer rotary cut products in diameters ranging from 3mm to 100mm using any of our Vyon® roll materials up to 4.75mm thick. Our rotary cut discs have excellent edge finish, which along with their rigid material properties, makes them ideal in automated product assemblies.

Vyon® Punched Parts

Porvair Sciences is the leading expert in converting our Vyon® porous plastic sheets and rolls into final shapes. Complex flat shapes, which cannot be rotary cut, can still be expertly manufactured by us at Porvair Sciences. Converted from our Vyon® roll and sheet material, Vyon® punched shapes can be efficiently punched to the same outstanding quality as our other cut products.

Vyon® Mouldings

Our flexible Vyon® moulding facility allows for simple and complex intricate component manufacture. We can offer an elevated level of design flexibility from a large selection of material options. Our moulding expertise allows us to offer moulded products in varying levels of complexity; shapes may vary from simple pipette tip filters or sample preparation frits to highly complex shapes. We can also offer a prototyping service on our moulded products ensuring a quick a supportive process when helping to develop your Vyon® moulded product. Vyon® moulded components can be further enhanced by the use of additives; including CMC for its self-sealing properties, colours or activated compounds such as silica to create a composite frit for SPE.

Vyon® Machined Shapes

Transforming Vyon® materials into larger, simple and complex products is a service that Porvair Sciences excels at. Using our CNC routing facility, contained within a controlled temperature and humidity environment, Porvair Sciences offers an extremely versatile way to create complex shapes. Our carefully monitored and fully enclosed manufacturing area ensures that even the tightest of tolerances can be maintained over largest of dimensions. Using our machining process we can offer Vyon® with clean cut, well defined edges ensuring a good fit into components such as industrial scale chromatography columns, filter housings and other systems. Various additional features, such as holes or steps, can be incorporated easily into the product design. This allows us to offer product components which are easy to assemble into location and remain secure when in use.

Vyon® Fabrications

Vyon® roll and sheet material can be fabricated to create alternative 3d shapes. Our unique expertise makes us world experts in products such large fabricated cones and tubes.
Our many years of experience makes us world experts in products such as fluidisation cones, the rigid and self-supporting Vyon is fabricated to complex and tightly tolerance designs. At Porvair, we can incorporate design features such as flanges, spouts, and ribs into our fabricated cones. Vyon® tubes are expertly seam welded to our customers designs and can be supplied with additional features such as end caps or adaptors. These tubes can be further processed into standard or customised filter cartridges for various liquid and gas filtration, sparging and other applications.
