Manufacturing Capability — 20,000 m² Facility, In-house Machining and Assembly

1. The plant in numbers

Sunswell manufactures in Zhangjiagang, Jiangsu — a city on the Yangtze about two hours from Shanghai that has become the centre of China's beverage machinery industry. The facility covers 20,000 m² and is organised as a single flow from raw stock to the test bay.

2. What is made in house and what is bought in

No machinery builder makes everything. The honest question is which parts are made in house, because those are the parts that define machine behaviour and spare-part availability five years from now.

2.1 Made in house

• Base frames and machine bodies — welded, stress-relieved and machined flat
• Filling carousels, star wheels, guide rails and neck-handling grippers
• Filling valves in all four types: load cell, volumetric, mechanical, semi-electric
• Capping turrets and torque heads
• Blow moulding clamp stations and stretch-rod assemblies
• Format and change parts for every bottle size you run

2.2 Bought from named suppliers

• PLC, HMI, servo drives and VFDs
• Pneumatic valves, cylinders and air preparation units
• Bearings, linear guides and gearboxes
• Sensors, safety relays and electrical protection devices
• Blow moulds — made by specialist mould shops to bottle drawings

3. From order to crate

1. Technical clarification (1–2 weeks). Bottle drawings, preform data, product properties, target output, utilities, market and certification requirements are fixed in writing.
2. Design and drawings (2–3 weeks). Layout drawing, utility schedule and machine general arrangement go out for buyer approval. Nothing is cut before approval.
3. Procurement (runs in parallel). Long-lead items — servo drives, moulds, specialty stainless — are ordered first, because they set the schedule.
4. Machining and fabrication (3–5 weeks). Frames, carousels and format parts are cut, welded and machined.
5. Assembly and wiring (3–4 weeks). Mechanical build, cabinet wiring, PLC programme load.
6. Water run and FAT (1–2 weeks). The line runs on water at rated speed. The buyer or a third-party inspector attends or reviews video and data.
7. Disassembly, marine packing, loading. Modules are wrapped, crated with desiccant and loaded with a photographic record.

4. Quality control built into the sequence

Inspection is not a final gate. It sits at four points where a defect is still cheap to fix:

The FAT report travels with the machine and becomes the baseline for site acceptance. If output at the customer's plant differs from the FAT figure, the gap is a utility or material variable, and having the factory data makes that argument short. Full detail is in the quality control and FAT process .

5. What the plant can produce

Output capacity matters to a buyer for one reason: whether your line gets built on time when the factory is busy. Sunswell has delivered 444+ lines to 71+ countries, with concurrent build capacity for multiple turnkey projects. Multi-line orders — the eight lines supplied to a single Kazakhstan group, for example — are staged so commissioning is sequential rather than simultaneous, which is what the customer's own team can actually absorb.
