Drainage and Water Management
Drainage holes, water reservoirs and overflow features require precise mold pins or inserts. Hole position, size and clean formation without flash are quality points.

Custom injection mold for plastic balcony and garden flower pots, supporting outdoor product development with drainage feature and UV-resistant material processing.
Plastic flower pots serve both functional and decorative purposes. The mold must produce parts with good drainage, UV resistance for outdoor use, attractive surface finish and durable construction at competitive production costs.
Shengqi reviews the pot design including overall dimensions, wall thickness profile, rim design, drainage hole pattern, saucer attachment, decorative textures and any self-watering or reservoir features before mold design.
Outdoor products face sun, rain and temperature changes. Material UV stabilization and mold design for consistent wall thickness contribute to product longevity.
Drainage holes, water reservoirs and overflow features require precise mold pins or inserts. Hole position, size and clean formation without flash are quality points.
UV-stabilized PP or HDPE requires specific processing conditions. Mold temperature control, cooling and shrinkage compensation account for these material characteristics.
Flower pots often feature textures, patterns or embossed designs. Mold texture etching, engraving and draft angle planning affect demolding and surface quality.
Pots are often nested for shipping efficiency. Taper angles, anti-jamming ribs and stacking lugs are designed into the mold to support nesting without sticking.
