Case Study: How a Perfume Bottle Factory Helped an Italian Brand Upgrade Design

Discover how a premier perfume bottle factory helped an Italian brand upgrade glass designs, achieving zero transit leakage and a 0.05% defect rate.

Client Background

A luxury fragrance company located in Milan, Italy, wanted to get a specialist perfume bottle manufacturer to help them release a new line that was eco-friendly. They were required to provide custom glass perfume bottles that had thick bottom square shapes, ultra clear flint glass and exact screw neck threadings. Vesseluxe has been chosen as their main perfume bottle factory because of our state-of-the-art glass molding machinery, consistent batch production and our support of the supply chain for B2B.

Challenge

Glass Distribution: Uniform wall thickness and heavy 25mm solid glass base.
Leaking Risks: Screw-necks mismatching thread and micro-evaporation during air transportation.
Color Fading: Exterior organic coatings that separate from the paint.

Cause Analysis

The engineering team found that thermal stress produced from a fast cooling rate was the cause for uneven base glass and that the mold had a slight amount of thermal expansion that caused neck thread deviations.

Solution

Vesseluxe redesigned the mold thermal control channels, optimized IS machine blowing pressure and used a dual layer UV sealant for chemical resistance against perfume oil formulations.
