Coil speed • valve switch accelerator

 
 
Consistent quality thanks to constant mould filling Electrohydraulic valves on pressure die-casting machines need an activation time of 25 – 35 ms under normal operating conditions, although the switching time can be more than twice as long if the machine is very warm, dirty (gummed) or old. It is not just the actual switching time that is the sole criterion here, rather the constantly changing switching times in the switching range.
As mould filling takes place within 40 - 80ms, varying valve activation delays of 10 to 15ms and more in the 2nd or 3rd phase are inacceptable as they can greatly affect the quality of the die-cast parts.
The upstream installation of a Coil Speed can reduce the activation time of the hydraulic valves by half (12 ms) and the repeatability to + - 1ms. This enables a very high level of constancy to be achieved during mould filling.
