Customer Requirement

The jar needed a natural stone appearance with irregular faces and recessed texture. A simple straight pull would create difficult release areas, so the structure had to be evaluated around realistic demolding rather than appearance alone.

Technical Issue & Judgment

The visual texture can remain complex as long as the release path is deliberate. Instead of forcing the entire jar through one opening, a controlled split line allows the silicone to open around the product. The seam should be located where later finishing is easiest and least visible.

Actual Production Result

Example outcome: a two-part mold strategy that preserves irregular surface character without relying on excessive silicone stretching.

What This Example Demonstrates

This demo case is structured to show how a mold project page can connect the product requirement, the key production variables and the engineering judgment behind the proposed mold structure.

Planning a Similar Project

Send the product reference, target dimensions or capacity, expected quantity and any production constraints. The first goal is to establish a workable mold direction before detailed tooling starts.
