1. Client Background
Our client, a well -known home fragrance brand of the United Kingdom, wanted to develop a special big diffuser bottle for their premium aromatherapy collection. Their goal was to create a statement piece that attended a long -lasting aroma experience and a more surprising scene on the larger living spaces. Due to our proven skills in large format glass production, custom mold engineering and packaging customization for delicate, high-value glassware, they chose Mosteb as their manufacturing partner.
2. Challenge
When the project seemed directly, two major technical challenges emerged.
First, glass big diffuser bottle are very likely to cracking or damage during the transport and packaging due to their weight and surface area.
Second, maintaining the same wall thickness during the blow-molding process proved to be challenging, as any minor inequality can lead to OPT pattle deformation or structural imbalance.
3. Cause Analysis
Our technical team conducted a fully analysis of the issue and identified two main reasons:
- Existing mold design lacks the best pressure distribution for large-volume glass, resulting in a variable wall thickness;
- Traditional packaging materials were insufficient to absorb vibration and effect during long distance freight.
To solve these problems, we redesigned the mold airflow system, distributed stress with 3D modeling, and closely collaborated with the client to validate packaging prototypes that can effectively protect heavy bottles during international transport.

4. Solution
- TIM Ptimise Mold Engineering: We introduced a reinforced dual-layer mold venting system to maintain continuous glass flow and equal wall thickness.
- Controlled cooling process: Adjusted the aniling cycle to gradually relieve internal tension in thick-walled regions.
- Protective Packaging Upgrade: Developed a multi-layer cushion solution with a molded pulp tray and shock-resistant external carton corresponding to the geometry of the bottle.
- Extensive drop and vibration test: Mixed that bottles can withstand the typical transport tension of foreign shipping routes.
5. Result
The final big diffuser bottle meets all operations and aesthetic requirements – showing complete clarity, balanced weight distribution and enhanced effect resistance. In the revised packaging design, the breakdown rate has dropped by 95% during shipping. The customer successfully launched its large composition diffuser line in multiple European retail channels, replacing it as a signature center product in their aroma collection.
