Our K-TECH® team carried out a Quick Check in the beginning of a joint project in the field of battery technology – a component housing cover for a rectifier – for a long-standing and well-known customer in the automotive industry. Our review showed that the use of the innovative LSR process leads to the best possible solution because LSR seals reliably even at high temperatures of up to 250°C without problems.
With regard to the process flow for the component housing cover, a number of improvements have been achieved using the 2C LSR process: In a single-stage production process, the LSR seal replaced the bonding of six separate silicone pads, which was previously necessary. The chosen combination of materials enabled the required chemical bond between thermoplastic and LSR. As for the hard component, an improved material selection was also able to minimize warping.
Overall, we were able to shorten production times and reduce costs. Thanks to automation, the project was characterized by high process reliability and high technical cleanliness. The optimized design also contributes to noise and vibration reduction.
