Antecedentes del cliente
Our customer is a Swedish wellness brand that specializes in premium mineral-enhanced water products. He demanded custom glass water bottles that reflect their commitment to purity, stability and elegant design. Their goal was to launch a new product line targeting health-conscious consumers in competitive retail environment. He chose Sí, sí. for specializing in sustainable, brand-monitoring custom botellas de vidrio-which is important to match the preference of Swedish consumers for environmentally friendly packaging.
Nuestros desafíos
The client required a delicate curvature and a unique custom glass water design with a matte-finish surface. However, during the prototype, the matte coating showed inconsistent adherence to the glass surface. Additionally, the thin neck design faced challenges for high speed lines, putting the production efficiency and leakage at risk.

Problem Analysis
Our engineering team identified that matte-finish inconsistency during the coating resulted in the surface temperature of uneven glass. The design of the narrow neck also caused turbulent flow during filling, causing potential split and slow production to rate. Both issues threatened product aesthetics and functional performance.
Nuestra solución
We implemented a dual-phase approach: optimizing the glass molding process to ensure consistent surface texture, and applying a advanced matte-coating technique with controlled temperature zones. For the neck design, we introduced a precision-engineered threading solution that maintained elegance while ensuring leak-proof performance and filling-line compatibility.
Resultados
The client received perfect custom glass water bottles with uniform matte finish and enhanced functionality. The improved neck design allowed 25% faster filling speeds without leakage. The successful launch strengthened their brand positioning, resulting in 30% sales growth within the first quarter and numerous retail expansion opportunities.
