The Different Types of Static Mixing Nozzles

Disposable static mixers are a great dispensing tool for two-part adhesives with different ratios. Also known as static mix nozzles, these accessories are used to mix the components as they make their way down a chamber before being dispensed. The mixing process often activates the adhesive or material being dispensed and begins the adhesion process.

Because there are so many different adhesive ratios and cartridge types, choosing the right type of static mixer can get a bit confusing, but we want to help. 

Types of Static Mixer Nozzles

There are several kinds of static mixers available in different forms. Each type of glue nozzle is suited to particular applications and has unique advantages and disadvantages.

In-line mixers are a type of nozzle mixer where components are placed as a permanent part of the dispensing line. Static dynamic mixers are a type of glue mixing nozzle that has moving parts but is not powered.  

Disposable static mixers take the form of a nozzle that attaches to either meter mix and dispense (MMD) or hand-held dispensing equipment. Their internal components can vary greatly depending on the needs of the application. The most common are the helical type and the box chamber type. Disposable static mixers are designed to be thrown away after use which can be cost effective compared to the flushing and cleaning necessary in non-disposable mixers. They also make sense for equipment which will handle multiple adhesive types.

Disposable Static Mixer Connection Types

There are a number of different ways to connect a disposable static mixer to your cartridge or meter mix equipment. The two most common connection types of static mixers are Bell and Bayonet.  

Bell Mixer – This type of static mixer connection will attach to a glue gun or more commonly, meter mix equipment using a retaining nut. After the nozzle is attached, the nut will slip over the top and screw into the equipment or gun.

Bayonet Mixer – This mixer is a twist and lock connector that is common for cartridge glue guns of all sizes.

Types of Disposable Static Mixing Tips 

There are also several different static mixer tips to fit different dispensing needs. The three most common are stepped, tapered, and Luer lock. 

Stepped TipThese tips can be cut at various points to increase the size of the adhesive bead being dispensed. The ends don't require any adapters or needles to adjust bead size. The downside comes when fine dispensing is required. 

Tapered Tip - Tapered tips are not adjustable, and for the most part, will not accept needles or fine tips. This is a simple and easy way to dispense common bead sizes. 

Luer Lock - Luer lock tips give users the ability to add adhesive needles or tips for precise dispensing. Often, this type of disposable nozzle style requires an adapter like the Sulzer Mixpac LA 05-00 Luer lock adapter. After the adapter is attached, the needles and tips can easily be locked into place. 

Choosing the Right Type of Static Mixer

You want to ensure that you get the right mixer for your specific requirements. The type of static mixer nozzle you need will depend on a number of different factors.  

  • Type of Connection- Different cartridges and dispensing equipment use different connectors. Users should always start with the type of connection required.
  • Dispensing Equipment - One key consideration is if the adhesive will be dispensed by a machine or a hand-held applicator. Disposable mixers are more frequently used for hand-held equipment and are compatible with various cartridge sizes. Machine dispensing applications may also use static mixers if adhesives are being changed or other mixing options aren't feasible.
  • Shot Size - A larger shot size/faster dispensing will require fewer mixing elements and a larger diameter opening. Because a larger diameter usually means less efficient mixing, a balance is required between the two. Smaller shot sizes require more mixing elements and a smaller diameter for an ideal mix.
  • Adhesive Characteristics - Thicker adhesive components require larger diameter openings to flow and mix properly. The difference between component viscosities will also affect the number and type of elements needed.
  • Size- You will also need to figure out what size cartridge or meter mix equipment you will be dispensing from. This will help determine what type of mixer nozzle you need.

Choosing a Static Mixer Nozzle Based on Adhesive

The materials you are mixing directly determine the range of elements needed to mix the materials into a homogenous material. Some materials are considerably more difficult to mix than others, so it is crucial that you have the appropriate amount of elements in your mixer to get the mix you need.


Some common materials you will likely be working with include acrylic, epoxy, poly-sulfide, PU foam, silicone, and urethane. Typically, the element range needed for each of these separate materials is as follows:

Material Range of Elements

Acrylic

8-20 Elements

Epoxy

15-24 Elements

Polysulfide

24-32 Elements

PU Foam

10-24 Elements

Silicone

20-30 Elements

Urethane

24-36 Elements

 

There are two factors that can indicate you should use a number toward the higher range. The first is the viscosity of the materials. If the two elements have very different viscosities (i.e. material A is 5,000 cps and material B is 150,000 cps), you will likely need to use the higher number of elements. The second is the material ratio. If you are dealing with a mixing ratio of 7:1, for example, a higher number of elements will be needed to achieve a pure, homogenous mix.

Frequently Asked Questions

Standard mixers are the oldest technology in two-part adhesive dispensing. These nozzles are round and come in a wide range of connection types. They typically require longer nozzles and more mixing elements to create the same mixing quality as Quadro mixers. 

Quadro mixers are the newest technology for two-part dispensing and are square in shape. They allow for more complete mixing in a shorter nozzle so users can get closer to their substrates when dispensing. There is also less wasted adhesive left over in the nozzle.
