Πώς να αυξήσετε την ποιότητα στη χειροκίνητη συγκόλληση

The so-called pump impact often has a negative effect on the manual application of adhesive. At the changeover point from the material pump’s start lift to low lift, short-term pressure fluctuations may occur that lead to increased or reduced material leakage at the applicator. It is important that the system is configured correspondingly well and the pressures are set correctly. The use of a material pressure regulator can minimize the impact. This helps with clean and even application.

Modern adhesives increasingly require a temperature conditioner to be able to be processed precisely. Epoxy resin adhesives, for example, are processed at temperatures between 40° and 60° C. Consistent and accurate temperature control is crucial along the entire system from the pump to the hose to the applicator. The applicator should therefore be designed specifically for heated systems and be well insulated to avoid injury.

Λόγω της τάσης για θερμοκρασιακή επεξεργασία του συγκολλητικού, ο σωλήνας υλικού πρέπει επίσης να μπορεί να θερμαίνεται και να αντέχει σε υψηλές πιέσεις λόγω του υλικού υψηλότερου ιξώδους, κάτι που αυξάνει το βάρος και τον όγκο του. Κατά την επιλογή των Συστήματα Εφαρμογής Υλικών χειρός, πρέπει επομένως να δοθεί προσοχή σε μια περιστρεφόμενη σύνδεση, ώστε ο εργαζόμενος να μπορεί να κινείται ευέλικτα και να μην εμποδίζεται από τον σωλήνα. Συνιστάται επίσης η χρήση ενός ισορροπιστή, στον οποίο μπορούν να κρεμαστούν το σύστημα εφαρμογής και ο σωλήνας. Αυτό φέρει το βάρος του συστήματος και μειώνει έτσι το φορτίο στον εργαζόμενο.

The ergonomics of the tool itself plays a major part in working productively and producing precise results. The applicator should be well balanced, have a large handle and if possible an additional handle. An additional handle helps balance the device better and prevents premature fatigue. In addition, the trigger affects the ergonomics: Pneumatic triggers are advantageous because the user doesn’t have to use as much force.

Producing an even adhesive bead is a particular challenge in manual applications. In practice, so-called hammer heads are a common problem in particular, for example, too much material applied at the beginning or at the end of the application. Devices that allow the material flow to be controlled provide a good solution. This distributes the material evenly and it can be individually adjusted depending on the component, application and application speed. This prevents hammer heads, reduces rework and improves the application’s overall quality and productivity.
