Need a reliable manufacturer for your custom design water bottle?

Corporation Process

Your Custom-designed Stainless Steel drinkware Manufacturer Factory In China

Custom Shape Water Bottle Tumbler Mold Tooling Processes

Step 1: Sign NDA

NDA is the abbreviation of Non-Disclosure Agreement. Before you expose any confidential information (such as drawing or design concepts) about your custom water bottle project, we sign NDA with you.

Step 2: Complete Design drawing

Basing your drawing, our engineering team will release DFM (Design For Manufacturing) report and help revise the drawing. If you only have a design concept but without drawings, our R&D team offers design support to complete the drawing.

Step 3: Quotation & Payment

After having all your requirement, we quote for both tooling cost and product pricing. Payment term for tooling is that, 50% deposit and 50% after sample approved by you. Payment term for mass production is normally 30% deposit + 75% balance before shipment.

Step 4: Tooling Fabrication & Sample Approval

Lead time of tooling fabrication is 5 weeks. You will get 3D printed prototype sample to finalize the design, and T1, T2 samples for final approval on your custom mold design bottle tumblers.

Step 5: Mass Production

After T2 tooling sample approval and receiving deposit payment, we start mass production. The lead time of mass production is 45 days. It’ll be even longer for custom design smart water bottle projects.

Step 6: Final Payment & Shipping

After receiving final payment, we will work with your forwarder to arrange the shipment. If you have no experience in importing from China, we can handle the whole logistics and arrange globally door-to-door shipping.
