Adhesive bonding

In addition to our research and development activities in the field of adhesive bonding technology, we offer you a wide range of services. Due to our industry-oriented approach, we are happy to provide you with advice and support tailored to the needs of your company and your adhesive bonding processes.

We offer our services along the entire production chain in plastics processing, starting with the determination of material properties for the formulation components and ending with the final assembly. If you have special requirements, please contact us. We will be happy to provide you with an offer tailored to your needs.

Do you have an adhesive bonding problem? Are you looking for a practical solution to determine specific adhesive bonding process or quality parameters? We will specifically search for suitable joining and testing methods for you, provide you with contacts and carry out preliminary investigations for suitability testing. We offer you comprehensive consulting services. Our broad and up-to-date overview of the possibilities and potentials of adhesive bonding technology enables us to respond to your individual tasks. This knowledge ranges from industrial methods to new technologies that are still being developed or are about to make the leap into initial practical applications. We are also happy to support you in the initiation and implementation of funded projects for the further development and adaptation of your products to the needs of the adhesives and plastics processing industry.

Feasibility studies and market analysis

You want to use a new adhesive and would like to test its suitability first? You are carrying out a material change? We investigate practical and theoretical adhesive technology feasibility for you and help you integrate the adhesive technology method into your process. Before investing in a new adhesive system/material change, we recommend a detailed investigation of the possibilities and limits of the process. SKZ offers you an independent assessment for this purpose. In feasibility studies, we check the suitability of adhesive systems according to your requirements and specifications. You will then receive a statement on the suitability of the adhesive or substrate. We carry out these studies in close consultation with you, either in practical production processes or on the basis of theoretical considerations. This feasibility study provides you with the certainty that your investment is on target and will subsequently lead to an optimization of your bonding processes and thus to higher efficiency. In addition, we are happy to support you in initiating funded projects for the further development and adaptation of your products to the needs of the adhesives and plastics processing industry.

Process development

Are you looking for a new joining process for metal/plastic joints? Or a suitable surface pretreatment for a fast-curing 2K adhesive? Whether 1K or 2K, solvent-based or solvent-free adhesives... we will be happy to develop an individual adhesive system for you for special tasks. This includes the surface pretreatment method and duration as well as substrate handling and adhesive selection. In doing so, we draw on our own development know-how and on existing solutions on the market and adapt them to your needs. The entire adhesive system development we offer covers optimal surface pretreatment as well as the correspondingly required adhesive selection and processing parameters. In close cooperation with you, we conceive, design, develop and manufacture bonded products for you as single pieces up to small series.

Non-destructive testing and process monitoring

Would you like to obtain information about your bondings that is not visible to the naked eye? SKZ offers the integration and, if necessary, individual adaptation of non-destructive inline measurement technology for process monitoring or as a laboratory testing method. In this way, for example, statements can be made about the curing progress of applied adhesives and bondings can be tested for application-specific quality characteristics. For example, it is possible to detect defects such as reduced adhesion, air and foreign material inclusions that lead to reduced mechanical properties.

For this purpose, SKZ offers a cost-neutral assessment of your testing task and enables comparative investigations with different methods based on ultrasound, terahertz, thermography and shearography, among others.

Training and Networking

As experts in the field of plastics technology, we strive to pass on the knowledge we have acquired over decades to our customers. From material development and manufacturing processes to the application of various testing and measuring methods - in our numerous practice-oriented training courses, you as a participant will acquire the necessary knowledge in dealing with plastics as a material. This begins with the selection of the right materials and compliance with production-oriented design rules, continues with the correct handling of equipment and machines for the manufacture and processing of plastic components and ends with the correct understanding of quality criteria and the associated use of testing and measuring tools.
Bringing together people from different areas of the company as well as from different industries to exchange experiences and technical know-how is also a top priority for us, in addition to the pure transfer of knowledge. Our numerous specialist events provide the ideal venue for a free exchange of ideas. Renowned speakers from a wide range of industries and excellent technical presentations make the SKZ conferences popular meeting places within the plastics industry.
