Headquartered in Huangyan, Taizhou — one of China's leading plastic mold manufacturing hubs — Taizhou Zhongyue Mould Co., Ltd. focuses on custom Plastic Chair Mould development for global furniture manufacturers. We design and manufacture injection molds for monoblock dining chairs, armchairs with or without armrests, stackable café chairs, children's chairs, and outdoor garden or patio lounge chairs. Our chair molds are engineered for stable high-volume production using PP, ABS, and PC materials.
Stool molds require balanced cooling for short cycle times and precise parting line control to avoid flash—especially on perforated or textured surfaces.
| Type | Common Variants | Design Focus |
|---|---|---|
| Round Stool Mould | 25–40cm dia., solid or vented | Tapered nesting wall, centralized/edge gate, anti-scratch nibs |
| Square / Rectangle Stool Mould | 30×30cm – 40×40cm | Corner cooling, stacking ledge, optional handle recess |
| Folding / Telescopic Stool Mould | Multi-stage telescopic, hinge pin holes | Tight tolerance on interlocking ribs, insert-molded metal hinge ready |
| Rattan / Textured Stool Mould | Imitation cane/weave pattern | Chemical etch VDI texture, deep cavity cooling, BeCu inserts |
| Children's / Bath Stool Mould | Small size, rounded edges, anti-slip pad recess | Safety radius draft, TPE grip insert option |
We calculate optimal draft angles and taper so stools nest tightly without jamming or scratching. Interference-check ensures 4–8 stools stack cleanly—important for retail packaging and logistics cost saving.
Stool cores (especially deep round types) retain heat. We design multi-loop baffled water lines in both core & cavity; BeCu (Beryllium Copper) inserts are placed at deep ribs or narrow legs to accelerate heat extraction—typical cycle time 30–45 sec.
Precision-guided mold base (DME/LKM/HASCO) with tight tolerance on cavity/core alignment prevents flash on rim and perforations. Critical for rattan-pattern stools with many surface grooves.
Pre-production MoldFlow simulation selects best gate location (fan gate / edge gate), predicts weld lines on visible surfaces (esp. textured areas), and verifies venting adequacy for vent/perforation zones.
Cavity can be mirror polished (SPI A1–A3) for gloss stools or chemically textured (VDI 3400 / rattan / leather / frosted) to add market appeal. Hard chrome plating optional for wear resistance.
