Custom Parts

Custom Parts

Since we’re primarily a job shop, the industries that use our products are widely varied. Customers can bring us completed product designs or even just basic concepts. Either way, we have the capacity to turn those into custom parts. 


custom mufflers


Along with our Ultra Quiet Mufflers and breather vents, we make many custom mufflers for use in automation and industrial pneumatic systems.

Filter elements

Filter Elements

We produce a wide range of filter elements from simple tubes, to complex shapes, in many different sizes. These can be used to filter air or water. Applications include use in breathing devices, drinking water, medical and lab equipment, and air preparation equipment.


Aeration and Sparging

Porous plastics make for an ideal substrate for aeration applications. The highly diffused pores allow for even distribution of air and can be adjusted to increase or decrease bubble size and volume. The addition of overmolded or welded solid parts can create disposable aeration devices that work with standard fittings. Typical applications include wastewater treatment, bio-reactors, agriculture, pond aeration, and fermentation. 


Vents are a common product made from porous plastic, it’s chemical resistant properties, low cost, and range of porosities makes it a great choice for many venting applications. Commonly used in battery vents, but most of these are made for custom made equipment that has to relieve pressure and keep foreign objects out.

Fluidizing – Similar to aeration, fluidizing will allow hard to move materials to flow easily.  We produce fluidizing bed plates, funnels, and tubes, all designed specifically for each application. This helps move construction materials like concrete, grain, as well as in food production.

Membrane supports – Porous plastics lack the ability to get very small and absolute pore sizes like a membrane can, but these precise films often require a support system. Porous plastic offers a great solution and can be adjusted to very high flow and high strength as well as chemical compatibilities.

Wicks – Porous plastics are almost all naturally hydrophobic, however some can be treated to become hydrophilic and act like a sponge. They not only offer consistent wicking properties, but also high strength and wear resistance. These plastics can be used in pen nibs, ink pads, and in automatic air fresheners.  

Sensor covers – the ability to make unusual and often complex shapes makes porous plastic a great material to enclose sensitive measuring equipment. Common applications for this include; monitoring air quality, ground water measurements, as well as sound and vibration monitoring sensors.

Complex and unique production processes

 Some of our customers come to us with very unusual and demanding needs. We pride ourselves in our ability to problem solve and work with customers to find innovative solutions. These innovations have led to increased production capabilities. These advanced techniques are things like: 

Overmolding – combining dissimilar materials in the molding process to achieve a unique single piece assembly. This can be two porous materials of differing porosities or varying physical properties, or it could be with solid materials including plastic or metal parts. 

Self sealing – The addition of materials that reduce porosity when the material comes in contact with water, has the ability to dramatically restrict air flow through the part. 

Coloration – Adding colorants to parts is something Pore Technology has been doing since it’s inception. This can be done to simply identify the difference between similar parts, or it can alter the parts physical properties, like increasing UV resistance.

Anti-microbial – Anti-microbial additives have been integrated into porous parts to enhance the antibacterial performance.

Joining – Most of the parts we make are used in custom assemblies. Some of those we complete by joining the parts together. We use a variety of methods to achieve this, including; 

  • Welding – heat welding is a way to the porous part with another plastic part that is non-porous. We use this process for our Ultra Quiet Mufflers, but also for many custom applications/
  • Gluing – Joining the porous plastic parts with either metal or other plastic components can almost always be achieved with adhesives. The porous part may not be chemically compatible with the adhesive, but still allow for a good physical bond. Making it able to bond with a variety of not only thermoplastics but also thermosets.  
  • Threads – Special physical traits can also be molded into the porous plastic. The unique high strength and wear resistant properties of VHDPE and UHMWPE mean that these threads have the capacity function well in many environments.
