Pioneers in
PET Mold Engineering
Rooted in Zhongshan since 2003, Zhongshan Jindong Machinery Co., Ltd. is one of the earliest pioneers in the region's PET mold industry. Operating from our self-built 8,000m² facility, we are a dedicated manufacturer, not a trading company. We define ourselves by our ability to solve problems--whether you need a single pilot mold to test a new idea or a high-efficiency production system to scale your business.



Built on Precision.
Driven by Partnership.
In the mold industry, customization is the standard, but performance is the differentiator. At Jindong, we don't just follow your drawings; we optimize them for your profitability. Our philosophy is that a great mold should pay for itself through faster cycle times and reduced downtime. We approach every project--big or small--with a focus on thermal efficiency and mechanical longevity, ensuring your custom tool runs flawlessly for millions of shots.
