Which equipment is needed to apply SABA adhesives?
Our water-based adhesives can be applied in several ways. Which method is best for you is dependent on many variables such as the substrate to be bonded, the production process, labor costs, available capital, etc. On irregular surfaces, adhesives are often applied using a contact-free spraying method. Flat surface bonds can be made with an automated roller system, with the adhesive being applied through contact between the foam and rollers. Below we explain the differences, and advantages and disadvantages of these two bonding methods. We also discuss hotmelt application methods.
Spraying Method
SABA adhesives can be applied by means of manual spraying. With this method, the adhesive is sprayed onto the surface to be bonded using a spray gun. This method of bonding is highly flexible and is therefore extremely well suited for bonding irregular substrates. This manual method is labor-intensive and is primarily used in the furniture industry and foam fabrication where substrates are irregularly shaped but manual spraying is also used in mattress assembly. There also the possibility of automated spraying, and although not widely used, it does bring advantages in certain manufacturing processes.
Rolling System
A roll coating machine is often used for bonding flat and large surfaces, such as foam sheets in mattress assembly. This machine contains rollers that precisely apply the adhesive to the surface to be bonded. This method of operation is cleaner in comparison with spraying because of the precision in application and the fact that there is no overspray. Furthermore, this automated process allows for the optimization of the adhesive application rate as this is both controllable and repeatable. Further, as a general rule, with a rolling machine the production rate is more consistent, resulting in higher production capacity and output. The acquisition of such a machine requires a much higher level of investment as compared to manual spraying thus production volume and company size play a major role in choosing the right application method.
Hotmelt
Our hotmelt adhesives can be applied automatically, as well as manually. With automated systems, the substrate is mechanically placed in the correct position, adhesive dosing starts automatically, and this is followed by automated pressing. With manual systems, these actions are performed by an operator. To be able to guarantee consistent quality, automated application is often preferred. Manual application of hotmelt adhesives has a few challenges. This is because the operator’s working method has a major impact on the end result, which means that there always is a chance of inconsistent application. In addition, the operator has to evenly press every substrate him/herself, as a result of which the mattresses are not all pressed the same way. The major advantage of manual application is its flexibility. The implementation of both methods is product and process dependent. Select one that suits your requirements, product design, and production process.
SABA has developed specific adhesives for every application and every application method. The key is selecting the right product and application method to optimize your production process.
