LET'S TALK DETAILS

Ready to Scale Your Plastic Manufacturing?

Get factory-direct answers and precise quotes for your packaging handles, custom PP/PE parts, and injection mold tooling. No middlemen, no surprises.

We are a 100% direct manufacturer with our own 20,000m² facility. We handle everything in-house, from standard plastic packaging handles to custom injection mold tooling, ensuring transparent pricing, strict IP protection, and reliable quality control.

Both. We hold massive ready-to-ship inventory for standard carton and beverage handles. Additionally, we provide comprehensive custom injection molding services for small plastic boxes, industrial components, and tailored PP/PE/ABS parts.

You do. 100% ownership of the custom mold tooling belongs to the customer once fully paid. We respect NDAs, strictly protect your intellectual property, and will never use your mold for other clients.

Absolutely. Our experienced engineering team provides FREE Design for Manufacturability (DFM) analysis and mold flow insights to optimize your 3D CAD files (STEP, IGES) before any production begins, saving you time and cost.

For our standard in-stock packaging handles, the MOQ is highly flexible with immediate shipping. For custom injection molded parts, typical mold tooling takes 15-25 days, followed by rapid mass production based on your volume requirements.

Quality is our top priority. Our manufacturing facility operates under strict ISO 9001 quality management systems. Furthermore, our products meet rigorous international compliance standards, ensuring you receive durable and precise components every time.
