About Watersy

The certified manufacturer behind your drinkware brand.

Factory glance

A single factory built to hold your spec.

Watersy is not a trading desk. It is a full OEM/ODM system with 40,000㎡ of self-owned floor, 300+ employees, and 27 injection molding machines under one roof.

That structure matters when specifications are tight: engineering, molding, coating, decoration, assembly and 12+ QC stages are coordinated by one team, so the sample you approve remains the product that ships.

It also gives brands a practical growth path: test with ready stock in Brazil or Indonesia, then move into custom tooling and full production without changing supplier or quality standard.

Inside the Factory

Nine steps that keep your spec intact.

Tooling, molding, finishing, cleaning, assembly and QC all stay on the same floor — so the product you approve is the product that ships.

Automated forming and stretching line inside the Watersy factory
01Automated Forming & StretchingAutomated lines hold wall thickness and geometry across long runs. For you: thermal performance stays stable when a project moves from trial to bulk.
In-house injection molding machines producing custom caps and lids
02Cap Injection Molding27 machines keep cap and lid production in-house. For you: the part customers touch most can be engineered as proprietary, not bought from a vendor.
Six-step Watersy custom product design process from concept and 2D design to prototyping, mold development and final production
03Mold DevelopmentTooling is reviewed before production. For you: fewer surprises between the approved sample and the first mass-production run.
3D printing workshop used for prototypes and custom tooling verification
043D Printing & PrototypingRapid prints bridge design and tooling. For you: shorter approval loops and less rework before the mold is cut.
Automatic polishing line for stainless steel drinkware
05Automatic PolishingMachine-controlled polishing keeps finish consistent. For you: the product feels finished, not industrial, from the first unit to the last.
Powder coating line applying color and surface protection to drinkware
06Powder CoatingElectrostatic powder coating controls color and texture. For you: surfaces stay retail-ready through real use and washing.
Automatic cleaning machine preparing components before assembly
07Automatic CleaningAutomated cleaning removes particles before assembly. For you: fewer contamination issues and a cleaner first impression out of the box.
Final assembly and multi-point quality inspection line inside Watersy
08Assembly & QC12+ checkpoints catch issues before shipment. For you: fewer customer complaints and smoother compliance audits.
High-volume automated production line for OEM and ODM drinkware programs
09High-Volume AutomationMultiple automated lines absorb peak demand without outsourcing. For you: launch dates stay fixed even when retail pushes volume.

Logo decoration, silk-screen printing and laser marking also run in-house. That keeps the last 5% of a custom project from becoming somebody else’s problem.

Innovation & IP

Differentiation lives in the cap, the structure, and the owner of the mold.

Bodies commoditize quickly. Our design work concentrates where buyers actually feel difference: lid architecture, carrying structures, large-capacity geometry, and the IP ownership behind each private project.

Your mold stays yours.

Tooling is registered under your brand and never opened for another client. NDA available before sample stage.

Watersy patented handle jug series with integrated wide handle
01 · Handle Jug · 3785ml shown

Watersy patented lid structure shown with product views
02 · Patent Lid · 1900ml shown

Folding Patent Lid

An arched metal handle mounts through rotating ears and folds flat. The flip sip port plus rotary plug gives dual sealing while allowing one lid to serve multiple bottle bodies.

Watersy patented ring-loop cap sports bottle
03 · Ring-loop Cap · 500–750ml

Ring-loop Cap Bottle

A full ring is formed directly into the cap, so one finger can carry the bottle without an add-on strap. A hidden flip port underneath preserves the clean silhouette for commute and fitness use.

Watersy patented thermal pitcher for desktop pouring
04 · Thermal Pitcher · 1200–1500ml

One-button Thermal Pitcher

A straight vacuum body meets a hawk-beak spout for controlled pouring. The top button opens directly, while the plastic-over-metal side handle stays comfortable during hot service.

Watersy patented sealed bowl with folding carry ring
05 · Sealed Bowl · 1005–1390ml

Wide-mouth Sealed Bowl

A low, wide bowl shape uses a metal-rimmed sealed lid, folding carry ring, and retained spring tether. The open format makes filling and cleaning easier for outdoor meals and storage.

Watersy patented handled ice bucket with reinforced body
06 · Ice Bucket · 7689ml / 260oz

Reinforced Handle Ice Bucket

Vertical ribs strengthen the bucket body and improve grip. A wrapped metal bail handle makes carrying comfortable, while the metal-rimmed opening supports a sealed lid for party, camping, and beverage service.

Representative patent-series designs are shown from the Watersy 2026 catalog. Patent numbers, patent types, and registration countries are not printed in the catalog and will be added only after the legal patent list is supplied.
