Production of fittings

Case 1 Production of Manholes

Project-task:

Design a production method to economically manufacture large injection-moulded products, in a large variety of manhole-types by:

reducing the investment in mould-parts
ease of mouldchange
allow large injection volumes with low plastification rates and limited energy-use
reduction of equipment size
