How to Choose the Right Static Mix Nozzles

Adhesives are necessary for a wide range of manufacturing processes, and they may have different compositions to suit the needs of a project. For instance, two-component structural glue is better than general glue in sticking larger load-bearing objects. To make that, you’ll need the right static mixing nozzles to mix the glues effectively. These mixing nozzles can do more than mix two components, as they conduct continuous reunification and cutting to create a uniform mixture.

Nowadays, you’ll find different static mixing nozzles ranging from square to round tubes. The right product will depend on certain factors, such as your needs and equipment. Round mixing tubes are suitable for automatic coating equipment. For manual gluing, you can go for either round or square tubes. Here’s a simplified guide to help you choose the best static mix nozzles.

Check the viscosity of the adhesive.

Thicker glues require nozzles with a thick diameter. Consider longer and narrower nozzles for thinner viscosity glue.

Determine the required output

How much material should you accomplish at once? Some applications will require more adhesive, so they may fare better with a larger diameter nozzle. Applications that need smaller volumes of adhesive can use mix nozzles, that can accommodate a needle, such as the spiral or bayonet-type.

The interface

Static mixing nozzles can adopt a bayonet form or a spiral type. The working principle involves cutting, shearing, rotating, and remixing the glue with the spiral blade several times before dividing it into many small parts. The spiral blade rotates glue to the right or left, changing the flow direction at intervals to push the central fluid to the periphery while pushing the surrounding fluid to the center. This way, glue is mixed appropriately.

The adhesive’s mix ratio

The close mix ratio (1:1) is ideal, but some projects may require a wide mix ratio (10:1). Specialty static mixing nozzles may be necessary for some applications. In that case, you should work with a reputable manufacturer of disposable static mix nozzles for custom solutions.

Not sure which product to get?

Consult with the manufacturer of mixing nozzles or consider having custom nozzles made. They will work closely with you to help you make informed choices and deliver the best static mix nozzles you require.

Key Features of Static Mixing Nozzles

Some applications require two-component structural glue for better performance and results. It’s more reliable than conventional glue, but it needs special tools, such as static mixing nozzles, to manufacture. When used with static mixing tubes, the nozzles simplify the creation of two-component structural glue in a particular ratio to make the adhesive ideal for sticking large load-bearing materials.

Their significance in making better adhesives

Single- and two-component glue products typically come with different systems when the glue is involved. The latter consists of components A and B. Before use, they must be mixed to a specific ratio using a static mixing nozzle. External forces don’t affect the static mixing tube as only the fluid is used through the mixer for continuous cutting and reunification until the components result in a uniform mixture.

Automatic coating equipment typically requires round mixing tubes, and manual gluing may consider round or square tubes. The choice ultimately depends on the unique requirements for making the adhesive and its purpose.

Features to consider

Static mixing nozzles, are classified according to their form. Here’s an overview of each:

Bell mouth: This mixing nozzle suits 200ml and 400ml AB glue guns. It can also function with a two-component liquid mixing machine.

Bayonet: Most static mixing nozzles are spiral or bayonet-type. The working principle is after the glue comes out from rubber hose A and rubber hose B flows through the tube. It can be cut, remixed, rotated, and sheared by a spiral blade several times before it’s divided into several small parts. A spiral blade makes the glue flow rotate to the left or right to change the direction of the flow. This way, the central fluid goes to the periphery, and the surrounding fluid can move to the center for an adequate liquid mixing effect.

Twist Lock-type: These static mixing nozzles are for new 50ml glue guns. They come in different types to suit specific glue mixing ratios, such as 10:1 and 1:1. They can replace mixing tips like DP100, 3819, 08115, 08193, and 08194.

Get the right nozzles.

Static mixing nozzles must be based on standard usage specifications. These are consumables, so they require regular replacement. A handheld branch adhesive can be mixed automatically in every component’s correct volume ratio. In general, a uniform color distribution determines a homogeneous mix. The adhesive should cure quickly after mixing.

Some Key Information About Static Mixing Nozzles

Glue is a widely used adhesive, and there are different types to suit every purpose. Aside from choosing the correct adhesive, you also need to pay attention to the formulation. Using two-component structural glue mixed in a specific ratio can make it better and make structural glue stick to larger load-bearing objects. Static mixing nozzles can help you achieve that. Here, you’ll learn some essential information about them to help you make informed choices for your application.

How are they different from standard mixing nozzles?

Standard static mixers are the oldest technologies for two-part adhesive dispensing. Their round nozzles have different connection types, and they typically need longer nozzles and additional mixing elements. Newer static mixing nozzles have better construction and parts to prevent wasting adhesive and leftover glue. Moreover, it allows users to dispense much closer to the substrates.

How are they used?

Two-part adhesives like silicons, urethanes, MMAs, and epoxies need plastic static mixing nozzles to effectively mix and dispense the A and B sides. Both materials will go into the static mixer to run through elements, a series of chambers that mix the two sides and activate curing. The nozzles can bring savings and boost productivity when manually mixing and dispensing two-part adhesives.

Benefits of using a static mixing nozzle

Injection molding processes rely on a static mixing nozzle for low-pressure drop and high mixing efficiency. The nozzles are made of durable hybrid components, which are resistant to corrosion and applicable to many industrial purposes.

A static mixing nozzle can provide many advantages, such as the following:

Reduced costs for raw materials

Minimize defects

Improve the dimensional accuracy of products

Reduce the molding cycle

Better quality when producing products from recycled materials

Types

Static mixing nozzles come in two different sizes as determined by their bell-mouth. You’ll also find bayonet and twist-lock types. Static mixing tubes have an interface that resembles a spiral-type or bayonet form. Thus, the liquid glue can be sheared, cut, rotated, and remixed several times after coming out of rubber hose A and rubber hose B; and flowing through the mixing tube. Then, the glue can be divided into smaller parts.

Important Tips to Consider When Installing Epoxy Mixing Nozzles

Epoxy is an incredibly versatile adhesive with numerous applications, from carpentry and woodworking to metal equipment.Butit’s also quite unstable, and incorrectly mixing resins can lead to major problems.Because of this, you will need the properepoxy mixing nozzleto complete your project!

Here is everything you need to know about epoxy glue and how to use it:

Epoxy has two parts: resin and hardener. It’s essential to mix them only once you’re ready for gluing, as its pot life only lasts for a few hours at most. In addition, you’ll need to be accurate with the ratios as much as possible; otherwise, it could cause a hot spot and lead to cracking.

Types of epoxy mixing nozzles

Static mixers do not contain moving components and blend liquid materials using flow current. They are primarily used for two-component rubber cylinders and dispensing machines, but they have many other applications.

These mixers are the most affordable and need little maintenance.However, they also require more manual labor. Their tubes can be divided as follows: bayonet type, bayonet mount type, round mouth, and self-threaded.

Dynamic mixers blend liquid components with a rotatingmotor. As a result, they are more efficient and consistent, better used for sensitive liquids.These mixers are primarily used for electronic production, electrical manufacturing, automotive manufacturing, and more.

Tips for mixing your resins properly with an epoxy mixing nozzle

Measure your resins and hardeners accurately with a digital scale or mixing cup. Generally, a 2:1 resin-to-hardener ratio is recommended.

Mix the solution for two to three minutes or until it is thoroughly blended

Avoid applying epoxy resins in cold temperatures or high humidity

Use high-quality epoxy mixing nozzles from trusted suppliers

Make sure to start pouring the mixture immediately, especially in larger quantities

Choosing your mixer

Ultimately, your choice of mixer and mixing nozzle will depend on your needs. For example, static mixers may be the best option if  using multiple adhesives. This is because they require no energy to operate, and the nozzle can be changed according to your desired rate.

For static mixing nozzles, make sure to consider their shot size and shot frequency.

Why Should You Use a Manual Glue Gun?

Are you looking for a way to apply your epoxy resins safely and consistently? If so, a manual glue gun is your best bet.

Manual glue guns vs. pneumatic glue guns

Epoxy applicators come in various forms, including manual, pneumatic, and battery-driven dispensers. They come in the shape of a pistol, with a secure grip design and trigger mechanism that allows you to control the amount of resin you dispense.

As the name suggests, manual applicators are operated manually and generally much lighter than their alternatives. Meanwhile, pneumatic glue guns require air or gas pressure to work, better for handling mid to high-level applications.

The benefits of using manual glue guns

No power consumption

Unlike hot glue guns, manual applicators do not require electricity to function. The operation is simple, so you can freely control the glue to minimize waste. In addition, the manual operation allows for better efficiency, especially for low-level applications.

Wide range of applications

Manual epoxy dispensers can be used in various industries. For example, they are mainly required for construction, automobiles, pipework, electronics, food packaging, and more. Additionally, they can apply multiple materials, including polypropylene (PP), polyethylene (PE), nylon, and even metal.

High build quality

Manually operated glue guns from trusted providers are made only with the best materials. Moreover, they are designed to be used comfortably, featuring an ergonomic handle and a portable build.

Low cost

Manual glue guns require no electricity to function, making them incredibly affordable to operate. Not only that. Their initial cost is significantly lower than pneumatic glue guns, reducing your expenses further.

Not sure which glue gun will work best for you? First, ensure it is appropriate for your required mixing ratio, preventing incorrect applications and measurements. In addition, buy your manual AB glue guns from a reliable and experienced manufacturer specializing in high-quality dispensing systems!
