Located in Huangyan, Taizhou—widely known as China's Mould Capital—Taizhou Zhongyue Mould Co., Ltd. is a professional Flower Pot Mould (Planter Mould) manufacturer specializing in custom injection mold solutions. We design and build molds for nursery seedling pots, round garden planters, square and rectangular flower pots, hanging baskets, and matching saucers or trays. Our molds are engineered for high-speed production using PP, PE, and UV-stabilized compounds.
| Type | Typical Size / Feature | Design Focus |
|---|---|---|
| Nursery Seedling Pot Mold | 8cm–20cm (0.5–2 gal), tapered | Ribbed bottom, drainage hole sleeve ejector, nesting stack |
| Round Garden Planter Mold | 20cm–50cm+, with/without rim & handle | Imitation rattan/stone texture, thick wall & reinforced rim |
| Square / Rectangular Pot Mold | 15cm–60cm, modern style | Sharp corner cooling, nested design for logistics saving |
| Hanging Basket / Half Pot Mold | Wall-mounted or chain-hung | Cored hanger hole, uniform thin-wall fill |
| Saucer / Drip Tray Mold | Match pot diameter | Flat cooling, anti-warping, multi-cavity option |
Flower pots require bottom drainage. We use ejector sleeve (sleeve pin) mechanisms to form clean drainage holes and simultaneously act as ejector pins—eliminating secondary punching and preventing flash around holes.
Cavity surface can be mirror polished (SPI A1–A3) for gloss planters or chemical textured (VDI 3400) to imitate rattan weave, terracotta, stone or wood grain—adding market value to your pots.
Tapered walls with calculated draft angles allow pots to nest tightly for compact storage and lower shipping cost—a key selling point for export markets.
Deep cavities risk uneven cooling. We design multi-loop baffled water lines in core & cavity; BeCu (Beryllium Copper) inserts are placed at deep core tips to accelerate heat extraction and reduce cycle time.
Pre-production simulation checks fill balance, weld lines near ribs, and venting needs—especially important for tall tapered pots and textured surfaces.

Taizhou Zhongyue Mould Co., Ltd. designs Plastic Dust Bin Moulds by addressing issues such as uneven barrel expansion, stress concentration at the rim, and deformation under heavy loading conditions.
We reinforce the upper rim and base structure while optimizing cavity balance, ensuring the bin maintains shape integrity even when exposed to long-term outdoor use and heavy filling.
Lid misalignment is often caused by tolerance deviation in hinge positioning. We control this through precision machining and strict assembly alignment during mold manufacturing.
Yes. We can develop molds for pedal-operated dust bins by integrating linkage structure precision, ensuring smooth motion and reliable long-term mechanical performance.
We strengthen handle zones with optimized rib transitions and stress diffusion design to reduce fatigue failure caused by repeated lifting and heavy loads.
Yes. By optimizing structural ribs and wall thickness distribution, we can reduce material consumption while maintaining strength and rigidity.
We design proper venting systems and adjust gate positions to eliminate trapped air, ensuring smooth filling and preventing burn marks or short shots.
We combine mold flow analysis, high-precision CNC machining, and durable steel selection to maintain consistent performance in long-term, high-frequency production environments.
Backed by 50+ team numbers and 20+ CNC machines, ZHONGYUE provides full DFM reports, T1 trial with sample video, and worldwide spare parts support. Contact us today for a customized quotation and mold design proposal for your Plastic Flower Pot / Planter Mould project.
