16 machine models · Own 5,000 m² factory · 60 granted patents
140th Canton Fair · Guangzhou · 15–19 October 2026
Buyers came with samples, drawings and market briefs. We talked about what is easy, what is expensive and what will not work — the same conversation we have on the factory floor. The booth is packed away; the work is not.

Counter-top dispensers, soda makers, portable and CO₂ — pick the shape first.

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.
We design. We dream it up, we draw it, we work out how it should feel in your hand.
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.
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.
total factory floor — injection, blow moulding, assembly, inspection and packing under one roof
our own dust-free blow-moulding workshop
soda makers
food-grade PET bottles from our own line
tested: every machine pressure-tested on the line by our engineers, every bottle checked for appearance and wall thickness
burst-tested on every production run — the bottles hold 1.8 MPa without bursting
Customer case
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.

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.
As a custom engineering brief, not as an existing catalogue promise. DRINKSIT is published at up to 10 L/h, about 220 ml per pour. Sustained 30 L/h, ambient / chilled / sparkling modes, adjustable dosing or module-only supply must be reviewed together because cooling reserve, heat removal, carbonation recovery, valve duty and service access all change. The commercial guide sets out what to send.
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.
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.
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.
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.
