Client Background
A German candle brand had a need for a trustworthy candle jar supplier that will supply them with a high quality premium candle collection. They selected Minghanggroup because of their custom glass-making capabilities, finishing options, and quality control. A total of candle jars with clear glass, straight-sided body, thick base, frosted lower section and minimalist printed logo.
Challenges
Visible Wax Stains
Wax residue appeared on the inner walls during filling.
Uneven Surface Appearance
Smudges on the glass jars affected the premium presentation.
Extra Cleaning Time
Workers needed additional wiping before labeling and packing.
Cause Analysis
Our team reviewed filling temperature, nozzle positioning, and jar handling. We found that splashing during wax filling and insufficient cooling before inspection caused residue and smears.
Solution
As their candle jar supplier, Minghanggroup refined filling procedures, improved nozzle alignment, and introduced a controlled cooling period. We also added inner-wall and exterior cleanliness checks before packing.
Result
The customized candle jars arrived cleaner, required less rework, and showed more consistent shelf presentation. Minghanggroup became the German brand’s trusted candle jar supplier for repeat orders.
