Mixing and Metering

The mixing and metering equipment provides all requirements to process the components (A, B and color batch) of the LSR silicone. Based on the size of the insulator components the right volume is injected into the mould through a static mixer.

The basic design of all silicone injection systems of the DOSKOSIL series is composed of a sturdy base frame to hold the components A and B. The silicone can be processed in commercially available 20 or 200-litre drums. The  specifically developed hydraulic electronic control ensures a synchronous operation of the dosing pump. The design of the equipment is standardized. For special applications, mainly in the high-volume range of inserted silicone, customised designs are available. The largest equipment for the injection of LSR silicone, the DOSIL ONE and DOSIL ONE ADVANCED series, is in the range of up to 80 litres within two minutes. Such equipment is mainly needed for the manufacturing of hollow core insulators. Larger units are available on request. The DOSIL ONE unit dispenses the silicone through a static mixing system in „one complete stroke“. The speed of injection can be electronically controlled during injection. An optimal filling profile of the mould is guaranteed.
