Hotmelt parts guide: Basics and functions of key hotmelt system components

 For many people, not all issues or information related to hotmelt will be immediately clear and understandable, so this article comes to the rescue. Understanding the role and importance of the various components of a hotmelt system is essential to ensure optimum performance and quality of the hotmelt. We will cover examples of different hotmelt parts and their applications in this article, such as heating hoses, glue application heads and nozzles.

Individual parts in hotmelt systems:

  1. Heads: Hotmelt heads are part of the hotmelt application equipment. They are used to apply the glue to the target surface. There are many different types of heads, such as jet (linear, spot); spray (spray, swirl-spray, micro-spray, random-spray); slotted The choice of the right head depends on the type of application and the gluing requirements.
  1. Modules: Hotmelt modules are typically used to control the flow of glue in dispensing systems. They are responsible for delivering a specific amount of adhesive at a specific time and over a specific area. There are many different types of modules, including spray modules, high-flow modules, slotted modules, etc. The choice of module depends on the needs of the adhesive application.
  1. Filters: Hotmelt filters are used in dispensing systems to prevent contamination and nozzle clogging. The filters remove dirt particles and mechanical contaminants from the glue to keep the dispensing system clean and efficient.
  1. Heating hoses: Hotmelt heating hoses are used to transfer and hold glue in a liquid state. The hoses are equipped with heaters that heat the adhesive to the correct temperature so that it is ready for application. Heating hoses are usually flexible and made of heat-resistant materials.
  1. Nozzles: hotmelt nozzles are the tips of the heads that allow precise application of the adhesive on the target surface. There are many different types of nozzles, such as single-hole, multi-hole, angle, spray, special purpose. The choice of nozzle depends on the dimensions of the glue application and the desired spread pattern.
  1. Heaters: Hotmelt heaters are used to heat the adhesive in dispensing systems. Heaters generate and maintain the correct temperature of the adhesive to keep it liquid and ready for application. There are different types of heaters, such as resistance heaters, induction heaters and ceramic heaters, and the choice depends on the specific application requirements.
  1. Temperature sensors: Temperature sensors are used in hotmelt dispensing systems to monitor and control the temperature of the glue. The sensors allow the temperature of the glue to be measured accurately and adjusted for optimum bonding parameters.

Advice on the maintenance and upkeep of hotmelt parts:

To ensure optimal performance and longevity of hotmelt parts, it is important to follow proper maintenance practices. Here are some tips:
  • Regularly clean and maintain pumps, glue application heads and nozzles
  • Monitor and adjust operating parameters such as temperature and pressure.
  • Carry out regular inspection and maintenance in accordance with the manufacturer’s instructions.

Not so hard!

In this article, we have provided a guide to the hotmelt parts that play a key role in the hotmelt bonding process. Understanding the role and importance of the various components of a hotmelt system is essential to achieving optimum performance and quality in bonding. Examples of different hotmelt parts, such as pumps, glue application heads, nozzles and control valves, have demonstrated their versatile use in various industries. Remember to maintain your equipment properly to keep your hotmelt parts in top condition and ensure long-lasting bonding performance.
