Jet Regulator Insert Part Mold Parting Plane Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection molding technologies for manufacturing insert parts for jet regulators often result in the formation of undesirable sharp edges and molding fins due to misalignment of mold halves, which can negatively affect the spray pattern and noise generated by the jet regulator.
Innovation Solution
The insert part is designed with two web structures arranged in superimposed planes, each with multiple webs, and separated by a mold parting plane. This design ensures that each web structure is defined by only one mold half, preventing overlap and minimizing the impact of mold misalignment on edge formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If injection molding technology is used to manufacture insert parts, then production efficiency is improved, but misalignment of mold halves causes formation of molding fins and sharp edges
Solution Approach 1:
The insert part is segmented into two web structures arranged in superimposed planes, separated by a mold parting plane. This segmentation allows each web structure to be defined by only one mold half, eliminating the problem of molding fins and sharp edges caused by mold misalignment while maintaining efficient injection molding production.
2Ease of manufacture
If traditional mold design is used, then manufacturing process is simple, but mold misalignment creates harmful molding fins and sharp edges
Solution Approach 1:
The harmful effect of mold misalignment is eliminated by extracting the web structures into separate planes defined by different mold halves. The mold parting plane separates the two web structures, so that each web structure is defined by only one mold half, preventing the formation of molding fins and sharp edges at the parting line.

AI summary
In order to simplify the manufacture of an insert part, which has two web structures, each of which forms a plurality of webs, it is proposed that the insert part is manufactured by a molding process in such a way that the two web structures touch each other in respective contact surfaces, but nevertheless remain separated from each other by a mold parting plane. This has the technical advantage that the respective outer contour of the webs of the respective web structure can be defined exclusively with a respective mold part without an offset of the respective other mold part having a negative effect on the shaping of the webs.
