About Zhong Shi Tong Industrial

Built for the parts that need to work every day.

For more than 17 years, we have focused on general injection molded products in Ningbo. Reliability is something we check at design review, tooling, sampling, production, and delivery.

Our approach

Engineering and production stay at the same table.

We keep decisions close to the final part. That means fewer handoffs, earlier answers, and a clearer view of what it takes to repeat the result at scale.

Ningbo is our manufacturing base

Ningbo connects mature mold making, resin supply, injection molding, finishing, and port logistics. We build on those local capabilities to support a practical path from first review to delivered parts.

Where we fit best

Bring us a finished drawing, a design that needs a manufacturability review, or a product program that needs a dependable molding partner. We work across household goods, foodservice components, electronics enclosures, tools, and other functional plastic parts.
