Nylon 6 Cast (Polyamide 6 Cast or PA6C) is stronger and stiffer than extruded Nylon 6, with excellent wear resistance, machinability, and heat aging. Available in natural and black.

Key Features and Benefits

High strength and stiffness: Offers excellent mechanical strength and rigidity, making it ideal for heavy-duty applications.
Good creep resistance: Maintains its shape and dimensional stability under continuous stress or load.
Easily machined: Despite its strength, Nylon 6 cast sheet is easier to machine than extruded Nylon, making it suitable for precision parts.
High wear and heat resistance: Withstands friction and elevated temperatures, providing durability in demanding environments.
Good temperature range (+105 to -30°C): Performs reliably across a wide temperature range, making it suitable for both low and high-temperature applications.

Typical Applications

Gaskets: With good creep resistance and dimensional stability, Nylon 6 cast sheet is used for gaskets, providing a durable sealing solution in industrial applications
Electrical Insulators: With excellent electrical insulation properties, Nylon 6 cast sheet is used in electrical engineering applications, protecting against electrical currents and providing safe, reliable performance.
Crane Sheaves: Thanks to its strength and wear resistance, Nylon 6 cast sheet is used for crane sheaves, offering durability in heavy-duty lifting applications.
Boom Pads: Nylon 6 cast sheet is commonly used for boom pads in construction and industrial machinery, providing excellent impact resistance and reducing friction between moving parts.

Colour Range and Applications

Natural Nylon 6 Cast Sheet: Offers exceptional strength and wear resistance, making it suitable for general engineering, automotive, and industrial applications.
Black Nylon 6 Cast Sheet: Enhanced with UV resistance, making it ideal for outdoor applications or environments with high exposure to sunlight.

Manufacturing Process - Casting

Cast Nylon 6 sheets are produced through a casting process, where liquid caprolactam is polymerised in a mold to form solid sheets. This method ensures:

Lower internal stress
Higher mechanical strength
Greater thickness capabilities

The casting process results in a material with enhanced dimensional stability, improved wear resistance, and excellent machinability, making it ideal for high-load and precision engineering applications.

Cut to Size Bespoke Fabrication Services

Our cut to size service allows Nylon 6 Cast Sheets to be purchased in exact dimensions, avoiding the need to buy full, manufactured sheet sizes.

Bespoke Fabrication Services Include:

CNC Laser Cutting: For precise and intricate designs.
CNC Routing: Suitable for complex shapes and large-scale projects.
Engraving: Perfect for personalised or technical detailing.
Additional Finishing Options: Drilled holes, rounded corners, and edge polishing for a professional finish.

Sustainability and Recycling

Nylon 6 cast sheet can only be recycled through specialised processes. However, its durability and longevity reduce the need for frequent replacement, making it a more sustainable choice for long-term applications.

We provide a fast delivery service throughout the UK using recognised Couriers such as Royal Mail, DHL, and Parcel Force.

Delivery prices are calculated based on the length of the longest side of the material ordered i.e. the delivery price of a panel measuring 1500mm x 1000mm would be based on the 1500mm dimension. Only one delivery charge is charged per order regardless of how many items are ordered.

Delivery Times

Our guidelines for delivery times are listed below:

Standard delivery (3-5 working days)
Express delivery (2-3 working days)

Express Delivery

If you require faster delivery you may wish to consider choosing our Express Delivery option at the checkout. Express Delivery orders are prioritised over standard orders and delivered using a recognised nationwide courier.

Next Day Delivery

Next Day delivery is not available via our website due to the volume and bespoke nature of orders we receive on a daily basis. However, if you need to place an order and require Next Day delivery please contact us – we will make every effort to meet your requirements and deadlines.

European/EU Delivery

We have temporarily disabled European delivery for orders placed through our website whilst we make changes to ensure that the correct rate of EU VAT is being charged. Our team can however manually process orders so please contact us if you require delivery to the European Union.

Remote Areas

Due to the nature of the ”made to measure” products we supply, we provide delivery prices at a standard rate and reserve the right to cancel an order should it become economically unviable to fulfill the order. In these extremely rare circumstances, the customer will be contacted first to discuss alternative options.

When delivering to some locations we can incur increased Courier delivery costs. Should delivery be required to one of the locations listed below a remote area supplement will be automatically added to the price of delivery during the checkout process.

Longest side	Remote area supplement
Samples (100mm x 100mm)	£0.00
Less than 500mm	£0.00
500mm to 1499mm	£10.00
1500mm to 2499mm	£15.00
2500mm or greater	£20.00

All prices listed include VAT.

Examples of delivery locations which may incur a remote area supplement are:

If you require delivery to one of these areas please get in touch to discuss your order.

Third-Party Deliveries

Some products are dispatched directly from the manufacturer and delivered by a third-party courier. If applicable, this is clearly stated on each Product page under the 'Delivery' tab/section.

Can I collect my order from Simply Plastics?

Yes, of course. Orders can be collected from our premises in Colchester, Essex. At the final stage of the checkout process there is a delivery option labelled "Collection/pickup" which is free. Once your order is complete, you will be notified by email along with our address and collection times.

I need my order urgently, can I pay for faster shipping?

Yes. We offer an express delivery service which aims to deliver all orders in 1-3 working days. Orders are delivered by a recognised courier company and may require a signature on delivery.

Do you have a minimum order charge or small order fee?

This is a question we are asked fairly regularly due to the previlance of either a minimum order charge or small order fee within the industry.

At Simply Plastics our approach has always been to treat all orders equally, small or large. We want all customers, new and existing, to be able to place orders with us confident that they are only paying for the products and materials that they require. We therefore do not have a minimum order charge or small order fee.

Is Nylon 6 Cast and Extruded waterproof?

Nylon 6 (both cast and extruded) is not fully waterproof. It is water-resistant, but absorbs moisture over time.

What is the difference between Cast and Extruded Nylon 6?

The main difference lies in how the material is manufactured. Nylon 6 Cast is stronger, tougher and has better wear resistance, whereas Nylon 6 Extruded is softer, easier to machine and more flexible.
