Thermostat housing for a 4-cylinder diesel engine
Customer:
Ros GmbH & Co. KG (Germany)
Product:
Thermostat housing for a 4-cylinder diesel engine in the Daimler group
Material:
Fibre-glass reinforced PPS
Product requirements:
A plastic and mould-friendly construction of a housing unit with an exceptionally complex geometry and a multitude of demoulding directions in order to complete manufacturing in one work flow allowing for tempering to stay within the target cycle time
Mould design and features:
The one-cavity injection mould includes a total of 18 individually controlled contours incl. sliders and core pulls that partly run into each other on multiple levels.
Contours, geometrical cross-over points and, in particular, the area of slider plates are modified in such a way that sharp corners, which are susceptible to wear and breakage due to the abrasive fibre glass PPS material used, can be avoided as much as possible.
