Inspection of raw materials for adhesive tapes at the highest level.
Our customer in Northern Germany employs around 600 staff and produces single and double-sided adhesive tapes on production facilities that are among the most modern worldwide. The specialty products and adhesive solutions are an integral part of industrial manufacturing processes, especially in high-performance industries such as the automotive, electrical, paper, printing, construction supply, healthcare, and pharmaceutical industries. They are distributed globally, primarily to Europe, Asia, and America.
The production of adhesive tapes requires considerable experience, expertise, and commitment. Additionally, the production must meet the high standards of various industrial suppliers. The plant in Northern Germany is certified according to the environmental standard ISO 14001 as well as the quality standards ISO/TS 16949 and ISO 9001.
The problem: Smallest metal impurities in raw materials
Raw materials for adhesive tape production can contain the smallest metal particles. Every tiny foreign body that enters production poses a significant risk. The basic rule is: the smaller the detected and removed particles, the better the protection against damage to processing machines and consumer complaints.
Even during incoming goods inspection, plastic processors can check the raw material by using foreign body detection systems and thus ensure its quality. If foreign bodies are detected and removed at the incoming goods stage, value creation losses can be avoided and the quality of the final products can be guaranteed.
The solution: Optimal metal detection using X-ray technology.
In the plastics industry, the use of inductive metal detectors is often common and sufficient. However, our customer aimed for the highest possible sensitivity in metal detection. Initially, tests were conducted with the most accurate metal detector available. However, the results did not meet the high expectations of the customer, who always strives for maximum quality. Thanks to Sesotec's wide product portfolio, X-ray technology could also be tested – this turned out to be the desired solution. The decision on whether metal detection technology or X-ray technology is the best choice was part of a comprehensive consulting process, which Sesotec accompanied as a competent partner. Due to the desire for the highest detection accuracy, the customer opted for X-ray technology.
The RAYCON X-ray system from Sesotec is a highly efficient device that detects all foreign bodies that absorb X-ray radiation better than the surrounding product due to their density, chemical composition, or mechanical dimensions – in short, foreign bodies that are denser than the actual product. Compared to conventional metal detectors, these systems offer the advantage of detecting a variety of dense foreign substances while operating with much higher detection resolution.
The customer benefit: A tailored solution for the customer
With the RAYCON, the customer has achieved the desired sensitivity. Metal particles that may be present in the raw material bags are reliably removed from the process, ensuring top-level quality.
This solution was only possible thanks to the support of a partner like Sesotec, who is interested in the specific conditions of its customer and works on it until the customer is satisfied. When standard solutions do not meet the requirements, Sesotec finds individual ways. Thanks to many years of experience in various application industries, Sesotec has the know-how to quickly immerse itself in the customer's processes and offer solutions with inductive metal detection technology or X-ray technology that can be perfectly integrated into any production line - from goods receipt to goods dispatch, in any type of conveyor.
Sesotec offers an extensive product range "Made in Germany" and works intensively with customers until the optimal solution is found. "With the RAYCON D+, we are on the safe side in terms of quality. Although the investment was higher than with a metal detector, the assurance that we will not have quality problems is worth the investment," says the operations manager of our customer.
