Custom colors, custom logos, custom shapes – it is what every brand wants.

But getting there without delays? That’s the real challenge.

You want a cooler or bottle that stands out.
New CMF. New look. New structure. Yes, just a new feel.

But here is the reality many brands face:
- Weeks on one tiny color sample.
- Miscommunication between your intended feeling and the real production.
- Delays that kill your launch plan.

We’ve been there, on your side of the table.

That’s why our OEM process starts before every drawing.
We listen, we clarify, we keep moving until we finish what exactly you need, without a headache.

How do we turn an idea into a finished drinkware or cooler product?

Not every brand starts with a ready-made mould.

Instead, most began with just an idea, a sketch, or even a picture with not-so-high resolution.

Over the last 50+ years, we’ve defined a clear, reliable OEM workflow that takes a concept all the way to a production-ready sample. Here is how it works

✅️ Customer brief: You share your idea, reference image, or your customers’ requirements. Then we will have the preliminary internal review meeting to double-check the project's feasibility.

✅️ 2D drawing: Our engineers(technical and design ones) turn the idea into a precise technical drawing. A second reviewing meeting with customers will be arranged in time to make sure the design is on the right track.

✅️ 3D modelling: We build a full 3D model to visualize shape, structure, and fit. Then discuss with customer again to ensure all details outside and inside are aligned with your expectations.

✅️ Prototype&mould: After all designs are confirmed, we develop the mould and produce the first physical prototype.

✅️ Sample approval – After test internally, the sample will be sent to you for test and awaiting for your feedback.

✅️ Once the sample is approved, cheers! We move into mass production with full quality control. We have over 100+ quality control personnel to safeguard the quality of your products. No guesswork, no surprise. Just 53 years of engineering experience behind every bottle and cooler…

A structured and reliable OEM process means faster lead times, lower risks, and a product that is ready to sell. We don’t like to say ‘ Almost ready’.

Whether you are launching a new drinkware project or upgrading an existing one, let’s talk about where your ideas fit in our workflow.

【The making of a GINT bottle series】- molding part

Every reliable part starts with reliable tooling.

Below is a look inside GiNT’s mold manufacturing workshop—precision machining the molds behind drinkware accessories and cooler accessories.

When tooling is controlled in-house, we protect what partners care about most: fit-and-finish, assembly consistency, and stable quality across high-volume runs in the long term.

How do you think the molding process makes sense to the final product? 👇

【The making of a GINT bottle series 】- step 6.

After vacuum and thermol testing. We come into the final steps:

✅Polishing: brings each surface to a smooth, mirror-like finish.
✅Painting lays on color with even coverage and durability.
✅Engraving turns personalization into lasting detail, line by line.
✅Packaging closes the loop: every piece is inspected, wrapped, and ready for whoever takes it home.

This is where raw metal stops feeling like material, and starts feeling like something you’ll use every day. ☕

【The making of a GINT bottle series 】- step 5.

Remove the air.

Each bottle goes into a vacuum furnace. It draws out gases hiding inside the steel, and the pumps clear what's left until almost nothing is in there. That "almost nothing" is the whole point.

With no air in the gap, heat has no easy way through. That's why your coffee can still be hot in midnight, and your iced drink still cool the next morning.

The hard part is getting the same result on every single bottle, day after day, that's what we need: the right equipment, the right timing, and the people who don't take shortcuts on the steps no one sees.

Next week: polishing and painting, make the bottle into a lifestyle gear.

【The making of a GINT bottle series 】- step 4.

The seam you can't see.
The seal you can trust. 💪

We use laser welding,a beam of light melts the steel where the two walls meet, making a bond stronger than the metal itself.

What it means for you:
✅ No extra material
✅ No weak spot
✅ No leaks over time

One tiny gap, the bottle will lose the insulation forever. That's why we don't take that chance.

👉 Next week: how we pull the bottle that keeps your coffee hot. ☕

【The making of a GINT bottle series 】- step Three.

Skipping ultrasonic cleaning? Here’s what happens next.

After step 2, the steel is still coated with oil, dust, and tiny metal bits from machining.If you skip real cleaning, this is what you may get:
💢 Gunk stuck in tiny gaps the eye can’t see easily
💢Weak weld areas that maybe crack under load
💢A higher chance of tiny leaks in the vacuum space later

That’s why we don’t treat cleaning as an extra step. Every cup goes through our multi-stage ultrasonic line.

✅ High standard makes high end product.

“Clean enough” never depends on who’s on shift that day.

How to kick off the new year 2026?

Bang! 💢 How about a drop test to set the tone?

👉From the roof of Gint/Redearth bus in factory.

👉Then, free fall. Three times.

New SK5000 cooler box with new materials, injection-molded. Challenge the motion that roto-molding is the only answer of durability and sturdy.

Here’s to a new year, built on engineering and proven performance.
