This page presents our core product categories and solutions in plastic mould packaging. With extensive experience in packaging mold design and manufacturing, we cover preforms, caps, thin-wall containers, and medium-to-large crates. Our core capabilities include multi-cavity hot runner systems, efficient cooling, in-mold closing, high-speed thin-wall molding, and IML compatibility. Each mold is customized based on product weight, cavitation, and production cycle, ensuring uniform wall thickness, short cycle times, and long service life. We also provide one-stop services from product optimization and mold flow analysis to precision machining and trial delivery, helping customers achieve stable mass production quickly.

Multi-Cavity Preform Molds

Focusing on PET/PP preform molding, we provide customized mold solutions with multiple cavities, weights, and neck sizes. The hot runner system and efficient cooling design ensure uniform wall thickness, high clarity, and low acetaldehyde content, making the molds suitable for high-speed injection molding and downstream blow molding.

Hinged Plastic Cap Molds

The mold integrates an in-mold closing mechanism that automatically folds and closes the cap hinge during mold opening. This eliminates the need for a separate folding process, avoids manual contact, and improves hinge consistency and sealing performance. It is suitable for flip-top packaging in beverages, condiments, personal care, and other applications.

Thin-Wall Packaging Molds

For thin-wall packaging products such as yogurt cups, ice cream cups, food containers, and lids, we optimize runner and cooling designs to support high-speed injection and in-mold labeling (IML). The molds deliver shorter cycle times, uniform wall thickness, good rigidity, and lightweight products, making them ideal for mass production.

Other Packaging Product Molds Solution

Covering molds for medium and large packaging containers such as plastic cheese buckets and crates, we provide one-stop services including product structure optimization, mold manufacturing, mold trials, and delivery. The molds feature high rigidity and long service life, meeting food-grade sealing, stacking, and load-bearing requirements.
