Process Optimization Cooperation to Increase Efficiency and Performance
Together for the first time, SurTec and Chem-Trend, two affiliates of the Freudenberg Group, will present innovative products at a joint trade fair stand at EUROGUSS 2020. Customers of both companies benefit from the close cooperation between the companies in research and development and from their standards for top-quality, environmentally-conscious products for a more sustainable production process.
Die cast components are becoming increasingly complex and the requirements on their performance ever greater, while demands for more sustainable production processes continue to increase. At each step of the production process, specialized process chemicals ensure that the components have been perfectly prepared for their respective purposes. When coordinated precisely, these process chemical specialty materials have an enormous influence on process efficiency. For this purpose the sister companies SurTec and Chem-Trend have joined forces.
“We are seeing an increasing need on the market for aluminum die casting alloys that are extracted from the molds with customer-tailored Chem-Trend mold-release agents. Afterwards, the modern, water-based high-performance cleaners from SurTec remove the release agents without leaving residues and optimally preparing the components for further processing,” explains Dr. Jens Krömer, SurTec’s director of global business development automotive. “The affiliated companies Chem-Trend and SurTec have already been collaborating successfully on this sort of coordinated technologies for several years. One example for such cooperation is a research project that was conducted in April of this year in collaboration with Braunschweig University, which investigated indepth the influence of the release agent on the cleaning and coating process.”
New Aqueous Cleaning Systems
High-performance cleaning agents, together with metal pre-treatment and functional and decorative electroplating constitute SurTec’s core areas of expertise. At EUROGUSS the surface technology specialist will present its latest developments in the field of aqueous cleaning systems
Complete chromium(VI) Substitute
Another main focus of the trade fair is the development of chromium(VI)-free conversion products for aluminum alloys that meet all relevant requirements and specifications of the automotive and aerospace industries. The technological benchmark in this respect is SurTec 650 for the pre-treatment of light alloys. This REACH-compliant technology sets standards for excellent self-corrosion protection, improved paint adhesion and adhesive bonding, weldability and a low electrical surface resistance. The new generation of chromium(VI)-free processes is set apart by easy handling, industrial robustness, possibilities for precision process control and especially by optimized process costs while at the same time maintaining extremely stable quality values.
New Series of Release Agents
At EUROGUSS Chem-Trend is introducing a new series of release agents based on newly developed polymers for structural casting applications that demand low porosity levels and high quality surface finishes. The new release agent technology offers protection from die solder while significantly reducing in-cavity and ex-cavity residues. This extends the service life of casting dies and increases the overall equipment effectiveness (OEE) of the casting systems. “Our custom-tailored solutions help die casters to attain the highest process efficiency in an environment with intense competition and to operate more profitably,” explains Darko Tomazic, Chem-Trend’s sales director for Germany. “The high effectiveness of our new formulations ensures excellent external temperature control of the casting die as well as better film formation on hot dies. These effects make it possible to use less release agent and shorter cycle times, which increases the profitability of the foundry.”
