Types of Precision Nozzles for Nordson®

For applying the right amount of glue in the right pattern every time, nozzle type and design mean everything. You can save time, money and glue by choosing the Nordson-compatible Keystone Industries precision nozzle that is best suited to your application. Take a moment to learn how to determine the correct nozzle type for your materials and process by understanding the different terms and nozzle specifications.
You don’t need to be an expert in industrial hot melt glue nozzles. That’s what we’re here for.
We’ll show you the difference between the various styles of nozzles so you can be confident you’re ordering the right nozzles for your business and adhesive application. Keystone Industries’ Nordson-compatible nozzles are built for precision and consistency and to offer greater control and durability than other nozzles you’ll find on the market, including many OEM nozzles.

Six Factors in Choosing Your Nozzle

Consider the following technical details when choosing your hot melt glue nozzle:
  • Pattern: Does your application call for dispensing glue in a bead, slot or spray pattern for adequate coverage and to ensure you get the glue exactly where it’s needed?
  • Number of orifices: Choose the nozzle with the correct number of orifices, ranging from one orifice for a single bead or spray to multiple orifices for multiple beads at the same time.
  • Style of gun: The style of gun relates to the control and positioning you need for your application. Your gun style will allow for certain types and styles of Nordson-style nozzles.
  • Nozzle angle position: The angle of the nozzle is in relation to the gun body. You can choose inline straight, multi orifice or 90° angles depending on the position & the amount of adhesive you require for your gluing.
  • Orifice diameter: Nordson nozzles range in diameter from .008” (small) for reduced adhesive flow and precision gluing to .040” (large) for greater flow and faster coverage.
  • Engagement: This is the length of the orifice channel, or the distance from the nozzle seat to the tip of the nozzle. Select a longer engagement if you want reduced adhesive flow but greater velocity.
When you consider all of these important points before ordering your nozzle, you’re giving yourself greater control over the volume, pattern and placement of your hot melt adhesive. This control means you’ll put the right amount of glue exactly where you need it for consistent and repeatable gluing for your manufacturing, packaging or installation applications. Choose the Keystone Industries precision nozzle for your Nordson hot melt equipment that improves the quality of your gluing process and ensures more reliable long-term adhesive bonds.

Which Nozzle Is Best for My Application?

Choosing the right hot melt glue gun nozzle goes a long way toward guaranteeing a clean and secure job. Your hot melt adhesive nozzle needs to be adapted to your industry, the materials you’re joining and the geometry and nature of your contact surfaces. Whether you’re seeking hot melt glue nozzles for carton sealing or another specific application, we’ve got you covered. Our team here at Keystone Industries can help you determine which nozzle is best for your application.

Depending on your industry and the type of gluing you’re doing, you can choose from:

  • Button nozzle: Single orifice brass nozzle that fits on Nordson H20 & Slautterback E100 Heads
  • Domed nozzle: Customizable multi-orifice brass nozzle suitable for case sealing
  • Domed circular nozzle: Used for sealing soda bottle base caps (circular pattern)
  • Extended dome nozzle: 1” long length to get adhesive deep into parts, suitable for automatic applications
  • Domed offset nozzle: These nozzles are available as single offset nozzles, which have one orifice at an angle offset from 0°, or dual offset nozzles, which have one orifice at 0° and another orifice offset at an angle for custom dispensing applications.
  • Domed SS nozzle: Stainless steel multi-orifice nozzle suitable for corrosive environments or high wear/contact
  • Handgun nozzle: Available in various lengths and orifice sizes for manual handgun operations
  • Needle SS nozzle: Commonly used to apply adhesive along a cardboard box seam and case closing
  • Pencil nozzle: Single orifice brass nozzle suitable for a variety of carton sealing applications
  • Short Pencil Nozzle: Single Orifice brass nozzle that give options for different flow rates of adhesive suitable for carton sealing applications.
  • Single guard nozzles: Button nozzle with integrated guard to protect the tip from box contact
  • Single SS nozzle (no guard): Durable stainless steel variant of button nozzle.
  • Spray nozzle: Dispenses adhesives in a swirl or spray pattern, for products such as diapers & certain product assembly applications
  • 90-degree nozzle: Popular nozzle for dispensing adhesive at a 90° angle for case and carton sealing

Understanding Terminology

When choosing your nozzles, it’s important to understand the different terminology used in the industry to make sure you’re choosing the right nozzles for your application. Consider terms such as:

  • Carton sealing: This popular use for a hot melt glue gun nozzle consists of gluing carton lids and tops, usually with a single line of glue (sufficient for low-weight cartons and products such as cereal boxes). Many customers choose pencil nozzles or 90-degree nozzles for carton sealing.
  • Case closing: Cases are made from thicker cardboard and often require more glue (thicker lines or multiple lines) for adequate sealing before shipping — heavier products will require more glue than lighter ones for adequate sealing. Optimal hot glue nozzles for case sealing include needle SS nozzles, right-angle 90° nozzles, and multi-orifice domed nozzles are popular choices.
  • Adhesive optimization: Too little glue can result in cartons and cases that open during transport, but too much glue costs you money. Optimizing your adhesive is important for the quality and reliability of your packaging as well as your profitability.
