On November 9, 2022, Zhejiang Inhe Industrial Co., Ltd. (Inhekids) commissioned a heavy-duty 4500 kN (450-ton clamping force) Haitian injection molding unit alongside automated support machinery at its Wenzhou production complex. This capital machinery expansion significantly elevates Inhekids’ technical capacity for single-shot molding of large-format plastic children’s furniture and structural play components.
Manufacturing heavy plastic parts—such as full-length slide chutes, large storage cabinet frames, and modular outdoor play structures—demands extreme clamping stability and high injection pressure. The addition of the 450-ton Haitian MA 4500 unit ensures uniform plastic melt distribution, preventing structural warping, sink marks, and weak weld lines across heavy-duty molds.
Key Manufacturing Advantages for International B2B Partners
Deploying this 450-ton heavy-duty injection machinery delivers distinct operational benefits for wholesale importers, cross-border retail sellers, and regional brand partners:
- Single-Shot Large Component Molding: High injection volume enables seamless single-piece molding of heavy structural components, reducing secondary joint assembly and boosting overall product durability.
- Synchronized Small & Large Part Production: Pairing the 4500 kN heavy unit with medium-tonnage auxiliary injection machines allows complete product sets to be molded in parallel, streamlining batch staging.
- Enhanced Dimensional Stability for Large Molds: Superior clamping pressure guarantees precise part margins, eliminating parting-line flash and ensuring consistent fitment during high-volume assembly.
This strategic machinery addition highlights Inhekids’ technical engineering depth, ensuring overseas buyers receive robust, defect-free plastic products backed by reliable, large-scale factory capacity.
