In-House Injection Moulding and Mould Maintenance
17 injection moulding machines producing ABS, PP and PC housings for cleaning appliances, with in-house mould maintenance and custom colours from 500 units.
Injection moulding is a process in which molten thermoplastic is injected into a steel mould to form a finished part in one cycle. Youwang runs 17 injection moulding machines producing ABS, PP and PC housings and water tanks for its own appliance platforms, which is why housing colour changes carry no tooling surcharge and start at the standard MOQ of 500 units.
When this process applies
This capability covers the housings, water tanks, dust boxes and internal brackets used on our robot vacuum, spin scrubber, car vacuum and pet fountain platforms. Moulds for these parts are maintained in-house. We do not mould parts for third-party product designs that we do not assemble.

| Typical parts | Housings, 3–4 L water tanks, 220–600 ml dust boxes, brackets |
| Colour | Black and white standard; Pantone-matched colours at MOQ |
| Mould maintenance | In-house; no third-party moulding for outside designs |
Where it is the right choice
- Appliance housings and cosmetic parts for our own platforms
- Water-bearing tanks in PP with gasketed interfaces
- Custom colours and logo tooling for private-label orders
- Internal brackets and structural parts where 90% of the bill of materials is made in-house
Where it is the wrong choice
Stating this explicitly matters more than a capability list: if your part falls into one of these categories, another process will cost you less.
- Moulding parts for products we do not assemble — we do not operate as a stand-alone moulding job shop
- Optical-grade lenses and light-guide parts that need Class-8 cleanroom moulding
- Metal injection moulding (MIM) and die-cast metal parts
- Single-sample quantities below the tooling-economics threshold
Equipment
- 17 injection moulding machines
- 15 surface-treatment units for finishing and printing
- In-house mould bench for cleaning, repair and spare inserts
Process questions
Can I get my product in a custom colour?
Yes. Black and white run as standard; Pantone-matched colours are produced at the platform MOQ (500–2,000 units by product) because the housings are moulded in-house and colour change is a material change, not a tooling change.
Do you charge tooling for colour or logo changes?
Colour changes carry no tooling fee. Logo printing is applied with the surface-treatment equipment; a new printing fixture, where needed, is quoted separately and is typically a low single-digit cost per order, not per unit.
Can you mould parts for my existing product design?
No. We mould for the platforms we assemble. If you need a contract moulding job shop, we will say so up front rather than quote work that does not fit our line.

SMT Assembly
Surface-mount technology (SMT) assembly places electronic components onto printed circuit boards at high speed before reflow soldering. Youwang operates 8 SMT lines with 7 Yamaha YSM20R high-speed placers and a Siemens HS60 line, handling 0201 components and BGA packages, with 5 AOI machines, 3 SPI solder-paste inspectors and 1 X-ray machine verifying every batch..
View capabilityAssembly & Testing
Finished-product assembly is the stage where motors, batteries, boards and housings become a working appliance, and end-of-line testing is where each unit is verified before packing. Youwang assembles on 4 finished-product lines supported by more than 50 pieces of test equipment, checking suction, sensor calibration, water-circuit leaks, charge cycles and WiFi pairing on every unit before it is packed..
View capabilityQuality & Compliance
Quality inspection for an appliance ODM order has two layers: end-of-line functional testing on every unit, and third-party compliance testing per destination market. Youwang performs the first layer in-house on 4 assembly lines with 50+ test instruments, and coordinates the second — CE, FCC, RoHS, CCC, PSE and UKCA test documentation exists for its product families and is available for review during supplier qualification..
