Dettagli del progetto
A Spanish beverage accessory brand wanted to develop a petal-shaped cup sleeve that was practical, non-slip, and decorative. The client’s original design had three main problems: the ribs were prone to breakage at the base, the petal edges were difficult to unmold, and the cup was not stable enough.
Z.S.R’s engineering team provided professional solutions through DFM (Progettazione per la produzione) assessment to address issues in the client’s original design: optimizing the rib and petal structure, adding a bottom suction cup design, and stabilizing the nozzle dimensions. This improved the product’s user experience and molding stability.
In base ai risultati del DFM, il progetto è passato alla realizzazione degli stampi e alla produzione dei campioni, seguite dalla verifica della qualità del primo lotto prima della produzione di massa.

Valutazione DFM in ambito ingegneristico
Rib Base Rounding and Cross-Section Optimization
ZSR ha aggiunto un Angolo arrotondato con raggio di 0.4 mm at the rib base, changed the rib tip to an arc, and changed the rib cross-section from triangular to a rounded trapezoid. All ribs are evenly distributed at equal intervals, and the height is uniformly adjusted to 0.6 mm.
The original design had right-angled rib bases, which easily caused mold adhesion and tearing during demolding. Stress during bending concentrated at the right-angle inflection point, and repeated use led to rib breakage. Adding a 0.4 mm radius rounded corner disperses stress, and the rounded trapezoidal cross-section reduces demolding resistance, improving the lifespan of the cup sleeve.
Petal Rounding Optimization and Base Thickening
All sharp corners of the petals are adjusted to a smooth 3 mm radius arc. The wall thickness at the base is increased from 1.6 mm to 2.0 mm, while the tip thickness remains at 1.8 mm.
During molding and demolding, the stress in the pointed petals concentrates at the sharp corners, easily causing whitening and tearing. The base and tip of the petals have the same wall thickness, resulting in insufficient strength at the base. A 3 mm full-rounded transition disperses the concentrated stress onto the curved surface, reducing the risk of demolding tearing. Thickening the petal base while maintaining the tip wall thickness balances appearance and structural strength.
Bottom Suction Cup Structure Added
Engineers placed four evenly distributed small circular suction cups at the bottom of the cup sleeve. The suction cup lip is thickened to 0.4 mm, and a 0.3 mm radius transition rounded corner is added to the base of the suction cup. A 0.02 mm vent groove is added to the suction cup cavity. The suction cup depth is uniformly 1.2 mm.
The added suction cup structure at the bottom of the cup sleeve prevents tipping. The thickened suction cup lip, combined with the rounded base to disperse stress, and the venting groove to expel air from the cavity, along with the 1.2 mm depth of the suction cup, creates a stable vacuum suction.
Realizzazione di stampi, produzione di campioni e verifica della qualità
Lavorazione dello stampo
Il gruppo ZSR è dotato di 10 centri di lavoro CNC avanzati and 4 macchine EDM, capable of creating silicone cup sleeve molds. Cavities undergo mirror polishing; petals, ribs, and bottom suction cup cavities are machined with high precision; suction cup cavities are individually polished to ensure a smooth, burr-free suction cup lip.
Stampaggio in silicone
La produzione è supportata da 48 macchine per stampaggio a caldo, 12 macchine per lo stampaggio di liquidie 13 macchine per lo stampaggio a iniezione del silicone, Consentendo 30,000 silicone cup sleeves to be rapidly molded within 20 days. Over 10 printing and spraying production lines also allow for printing logos or patterns on the silicone cup sleeves.
Vulcanizzazione secondaria
After molding, the silicone cup sleeves undergo secondary vulcanization at 200°C per 2 ore.
The secondary curing process removes small-molecule volatiles, reduces product odor, and ensures the cup sleeves meet food contact safety standards.
