Webcreator on line configurator
WEBCREATOR is a web-based design application for configuring Thermoplay Hot Runner Systems with standard nozzles and accessories. This generates high quality CAD 2D and 3D models reducing the production time.
The hot runner system is freely configured in relation to the distance between the nozzles and accounts for the polymer processing conditions. The diameter of the manifold channels, as well as of the descent holes to the nozzles and the injection bushing size are configured to suit.
After configuration the 2D drawings and 3D models are generated in the selected format and sent by email to the user in a single zipped file, which also includes the configuration sheet and part list (in pdf format).
Any configurations made can be modified to generate a new drawing later. WEBCREATOR does not perform any check on the configured system in relation to the injected polymer.
