Vacuum Shot Dosing Equipment for Optimum Casting of Electronic Components
Automotive ignition coils, sensors or small transformers – HEDRICH develops vacuum shot dosing systems for the highly precise potting of electronic components under vacuum. The partially or fully automatic special casting equipment can either be integrated into an existing production line as stand-alone unit or supplied as complete line including continuous tunnel drying ovens, plasma systems and continuous curing ovens.
The HEDRICH 3D casting system provides highest flexibility in production irrespective of height, width or geometrically variable part sizes. The casting nozzles are moved to the component and not vice versa. The up-to-the-rim filled parts are moved as little as possible to avoid spilling of the casting compound. Simultaneous movement of casting nozzles and pallets optimizes the casting process, thus minimizing the cycle times.
Most dosing supervision systems only detect a fault in the filling quantity during casting, thus generating unnecessary waste by casting errors. And then there is our new HEDRICH PreCHECKTM system! It recognizes an improper dosing of the cast resin components yet before casting, and therefore avoids waste.
The casting nozzles of all HEDRICH shot dosing systems are provided with ceramic-made closing pins as standard. These extremely wear-resistant closing pistons grant very long service life with a highly precise and drip free casting.
To increase the process quality assurance, all component-specific casting parameters are stored in a database system, enabling a detailed retraceability of each cast component.
