Liquid filter with box produced using primary molding technique and process for its production

摘要

"CASE-LIQUID LIQUID FILTER USING PRIMARY MOLDING TECHNIQUE AND PROCESS FOR YOUR PRODUCTION". The present invention relates to the housing configuration for a liquid filter, where the housing is shaped like a pot and is manufactured using molding technique. For fixing the lid to the housing (10), a thread (28) is provided which can be manufactured without cuts underneath. This is achieved within a zone (30) around the mold division (29) by the fact that thinning (31) is provided in the thread of the horizontal areas. Because of this, the manufacture of the thread in the box is possible without final finishing steps directly in molding technique, which saves manufacturing costs.
