Water first
Soda makers don't sell. Water does.
Ask a buyer what this is and you will hear “soda maker”. That names the mechanism, not the business. What sits on the counter is a counter-top water dispenser — an appliance the trade already knows how to shelve, price and sell.
And the machine is not the thing that gets bought twice. Water is. Sparkling is what turns water from the cheapest thing in the kitchen into something people choose on purpose — and once it becomes their default, they drink it every day.
That is the difference between a gadget and a line. A gadget sells once. A habit sells every month — bottles, gas and refills right behind it. Same machine, wider shelf, and now a reason to come back.

Two companies. One idea.
HK 4 Degree Co., Ltd
We design. We dream it up, we draw it, we work out how it should feel in your hand.
Foshan Mia Electrical Appliance Manufacturing Co., Ltd
We build. We tool it, we mould it, we inspect it, we ship it.
Because we build our own designs, nothing gets lost in translation.
Orders are contracted through Foshan Shunde Four Degree Technology Co., Ltd — same building, same team.
The part most brands skip
60 granted patents across 4° and MIA — 56 of them in force today. An 8-person R&D team. 10% of what we earn, put back into R&D — every year, not once.
We don't buy a machine, print a logo on it and call it ours. We start at the sketch, and we stay with it until the last bottle has passed inspection.

Customer case
Sparkling water, built into a fridge.
A global smart-appliance brand asked us to put carbonation behind a refrigerator door. We developed the module, tooled it, and proved it on our own life-cycle rigs before release — and it shipped in 2026.

Water. Juice. Cold brew. Wine. Fresh fruit — whole pieces, straight into the bottle.
CO₂ was never the fussy part. The machine was.

Questions buyers ask us
→ What does 4° actually make?
Counter-top water dispensers, with sparkling as the plus one. Sixteen machines in the current line-up: seven that carbonate almost any drink (SHANG, SONG, SING, SHANG-2, EDGE, WALL-SERIES, SMARTZZI); three classic water machines (G2, G3, SCARLETT); three portable models (FIZZGO, SODAP, SODAP·SE); the fully automatic DRINKSIT and DRINKSIT LITE; and the CO₂ cylinders and cartridges they run on — plus the bottles, cups and caps that go with them. “Soda maker” names the mechanism; counter-top water dispenser is the category it sells in.
→ Is 4° a factory, or a trading company?
Both, and we name all three companies. Contracting and export: Foshan Shunde Four Degree Technology Co., Ltd., founded in 2013. Manufacturing: our own plant, Foshan Mia Electrical Appliance Manufacturing Co., Ltd., built from June 2018 — injection moulding, blow moulding, assembly, inspection and packing under one roof. Design and export: HK 4 Degree Co., Ltd., founded in August 2019. We are not an office that forwards your drawings to an unknown third party.
→ How can I check that this factory can really deliver?
Look at the numbers that are hardest to fake. A 5,000 m² plant, including a 300 m² clean-room blow-moulding shop. 2,000 machines and 3,200 food-grade PET bottles a day. Two 100% high-pressure tests on every machine — one on the carbonation components, one on the finished unit — every bottle checked for appearance and wall thickness, and a 2 MPa burst test on every production run so the bottles hold 1.8 MPa without bursting. 60 patents granted across 4° and Mia, 56 in force, with the list downloadable — and inspection before shipment is yours.
→ Can you build our own model, and who owns the tooling?
Yes — we have done OEM and ODM since 2013. Start from a platform we have already engineered and change the finish, logo, bottle or packaging; or bring your drawings and our engineers take it to production. Tooling ownership and design attribution are written into the agreement before work starts, not argued about afterwards.
→ After the first order, what keeps selling?
The consumables, which is where the repeat business is. Water bottles in 350, 500, 700 and 800 ml and 1 L. CO₂ in 420 g / 0.6 L, 157 g and 74 g cylinders and 8 g cartridges, with the valve and the paperwork (TPED, DOT) to ship them filled — in the same carton as the machine — and a refill or exchange model for when the first cylinder runs out.
