Nylon 6 Rod stands as one of the most favoured engineering plastics, recognized for its versatility and widespread use across various industries. Over the years, it has received multiple trade names from different companies, solidifying its reputation as a highly sought-after plastic.

There are two primary manufacturing processes for Nylon 6 Rod: extruded and cast. Extruded Nylon 6 Rod is produced by heating the polymer and forcing it through a circular die. On the other hand, cast Nylon 6 Rod is created by melting the polymer and pouring it into metal tubes that are capped at one end and open at the top.

Drilling larger diameter cast Nylon 6 Rod must be approached with caution due to potential heat and vibration build-up. It requires very sharp drills and a gradual progression using incremental drill sizes until the desired size is achieved. Utilising coolant and a "pecking" action is essential.

All Nylon 6 Rods have the ability to absorb moisture, which may cause components to expand in damp environments. However, this is only significant if the finished components are exposed to operate under extremely tight tolerances.

Both manufacturing processes have their advantages. Extruded Nylon 6 Rod is slightly cheaper and is available in diameters ranging from 6mm up to 300mm. Engineers have reported that it may seem softer and not as easy to machine, making it more susceptible to melting during machining. However, it benefits from a wider size range and lacks blow holes. Cast Nylon 6 Rod, on the other hand, is reportedly easier to machine due to less internal stress resulting from the manufacturing process. Although rare, it has a minute potential for blow holes and is generally perceived to be more stable with lower internal stress.

Nylon 6 Rod is commonly employed for pulleys, bearings, rollers, and gears, among other applications. It boasts exceptional strength, withstanding forces of up to 1 tonne per square inch, and exhibits high impact resistance, wear resistance, and low friction. If you seek an engineering plastic that excels in various applications, Nylon 6 Rod is likely the ideal material for your project.

The majority of Nylon 6 Rod is manufactured in black or natural colours. Black Nylon 6 Rod, often containing an additive called Molybdenumdisylphide (MOS2), is preferred for industrial environments due to its self-lubricating graphite-type properties, providing extended longevity in wear or abrasive conditions.

Acetal Rod is primarily manufactured in Natural/White and Black colours, with Black being preferable for industrial applications. Additionally, we now offer blue Acetal Rod in stock, ensuring swift delivery for those with specific colour requirements.

A significant advantage of Acetal Rod is its minimal generation of burrs after machining. This eliminates the need for time-consuming deburring processes, saving valuable time and resources.

One key advantage of Acetal Rod is its minimal moisture absorption, enabling precise machining and dimensional stability, regardless of environmental conditions. This characteristic makes it an ideal choice for components expected to function in damp or wet environments.

Yes, Acetal Rod is an excellent choice for applications involving food. Its minimal moisture absorption ensures food safety by preventing bacteria absorption. Many companies in the food industry specifically request components machined from Acetal, and this is why we maintain a stock of Blue Acetal Rod. The blue colour facilitates easy visual inspection, simplifying the detection of debris without affecting the entire batch.

Acetal Rod demonstrates excellent compatibility with high-speed automated machining processes like CNC lathes. This allows for efficient, automated production, significantly reducing manual labour while producing finely machined parts.

Indeed, Acetal Rod is well-known for its slippery nature. This attribute imparts low friction characteristics to components and minimises initial stickiness. For small rotating components that require smooth initiation during service, Acetal provides an advantage by not requiring significant initial load, thus reducing jerking, which can be a real concern, especially in micro components.
