Secure gluing of paintbrushes

Within the production of paintbrushes and roller manufacturing, addressing challenges in the bonding process is crucial to ensure quality. This is particularly true for our customer, which specializes in producing a diverse range of paint brushes, ranging from 1/2” to 4” wide, with a daily output of up to 40,000 units. Dedicated to meeting the demands of various markets, their manufacturing process revolves around the precise application of a two-component epoxy into brush ferrules. The critical aspect here is to secure the bonding of bristles, ensuring a flawless end product.
In the previous production process, the customer encountered two main challenges. Firstly, inconsistent dosing led to defects in both the brush sleeves and the bristles. Secondly, there was a problem with the wasteful use of glue, which was affecting of course operational efficiency. To overcome these challenges, DOPAG implemented the economix metering and mixing system, a solution tailored to efficient and precise dosing in the production of brushes and rollers. The economix dispenses and mixes the two-component epoxy resin with high precision and reproducibility. Further, a timer control panel, tailored to accommodate different shot sizes, provides a high flexibility in the dispensing process. The system ensures a volumetric repeatability within <2%, depending on the specific application, guaranteeing consistency in dispensing. With the implementation of the economix, the company optimized the manufacturing process significantly. With the new system, the company achieves application rates of up to 120 shots per minute. The company could enhance their efficiency and their production speed. The precise dispensing capabilities of economix significantly minimized wasteful adhesive usage. Further, the customer was able to improve the product quality. The ultimate goal of ensuring secure bristle bonding was achieved, contributing to an overall improvement in paintbrush manufacturing quality.
