Method for manufacturing hollow body, involves forming multiple small half shells with partial forms, which represent together counter tool

摘要

The method involves forming the multiple small half shells with partial forms, which represent together a counter tool. The half shells are congruented to join in the contact zones. The half-shells are made of thermoplastic plastic. The half shells are of various sizes. The foil sections for the small half shells are clamped by negative pressure within a framework.
