Arnold Machine’s adhesive dispensing systems accurately place a specified amount of adhesive — usually a bead — to a part so components can bond together during assembly. Our automated spray systems, on the other hand, are ideal if adhesives need to be sprayed accurately over an area of a part as opposed to applying a bead of adhesive to a specific location on a part.
In order to ensure accuracy and reliability, Arnold Machine works closely with manufacturers to understand an adhesive’s properties and intended applications. This includes determining if preheating is required, establishing surface preparations for the part receiving the adhesive, knowing the adhesive’s tack time (i.e., the amount of time the adhesive takes to “set” or harden) as well as how much adhesive needs to be applied.
Our adhesive dispensing systems are carefully controlled to ensure accurate placement. In certain cases, Arnold Machine’s team employs an automated vision inspection system for accuracy. Proper placement requires complete control over an adhesive from a bulk holding system all the way to a part, which is why we employ metering devices. A metering device also guarantees repeatability.
Our first-rate adhesive dispensing systems have been perfected over years of experience and display:
- Integration into existing production systems
- Process control over a system
Our systems increase the consistency of a perfectly executed action because they guarantee repeatability, decrease the risk of human error and result in less material and / or part waste.
Method of application
We have extensive experience in adhesive application and can handle if (a) a part needs to be presented to a fixed dispensing head or if (b) a robot is required to move an adhesive to a part.
Presenting a part to a fixed head is optimal if only a dot of adhesive is required. However, more intricate applications generally require robots, in which case our team needs to determine a part’s geometry. For both methods, a pressure pot is employed to move an adhesive to a gun and air pressure is used to control the amount of adhesive being delivered to a part.
