In electrical engineering and sensor technology, very delicate components, which have to be manufactured using high-precision injection moulds, are often required. High demands are placed on the shape accuracy of the individual parts. The connection dimensions for add-on parts and consequently the system capability must be guaranteed, and minimum manufacturing tolerances must be met.
Very narrow tolerances and deviations in shape and position are the rule, especially for moulded parts for electrical systems. In order to be able to guarantee the desired characteristics of dimensional accuracy, high surface quality and delicate contours, a filling and distortion simulation (Moldflow simulation) is often carried out in advance, from the results of which the correct production measures are derived.
We use insert technology for demanding plastic parts with contact elements. Here, the metal inserts are fed manually or automatically to the mould. In order to ensure the correct positioning of the inserts in the series process, the coordination between mould and insert must be very precise. The insert is coated in the mould, which ensures a firm bond between the insert and the moulded part. We can offer and implement various processes for the production of injection moulds for insert technology.
Our moulds are also used, for example, in the production of components for conductivity sensors, which are mainly used for process monitoring in the beverage and food industries. Here, high requirements in terms of hygiene and sterility are guaranteed by the use of high-performance plastics (e.g. PEEK and PPS).
However, when it comes to monitoring processes in extreme environmental conditions, material properties such as mechanical, chemical and thermal resistance are particularly important. For this reason, the critical components (sensors) in these applications are coated with "filled" high-performance plastics. This guarantees a long service life, and the components are protected against corrosion and moisture.
Since the processing of high-performance plastics, from mould design through peripheral equipment and material pre-treatment to the process capability of the injection moulding process, is much more demanding than the processing of conventional engineering thermoplastics, however, we are the right partner for the successful implementation of your projects.
