Facility Tooling And Quality
Mould design tool making injection moulding assembly measurement and packing, in one plant in Zengcheng District Guangzhou. Every photograph on this page is our own.
From Drawing To Packed Carton
Six stages. The same route runs whether the part is a catalogue geometry or a new tool.
Drawing review
Your drawing or part number is checked against tooling we already own before anything is quoted.
Tool design
The mould is designed at the CAD station, with the section split pin positions and gate decided up front.
Tool making
Steel is cut on the wire cut EDM and CNC machines in our own tool room.
Injection moulding
Bodies are moulded in the specified thermoset or thermoplastic.
Assembly and winding
Terminals are inserted, and where the order is for a finished component the core is fitted and the part is wound.
Test and packing
Dimensional check in the measuring room, electrical check on the test bench, then packing.
Inside The Plant
Tool room, moulding, assembly, measuring room, test benches and finished goods.

What We Do Not Claim
Production capacity figures, export country counts and customer names are not published on this site because we would rather state nothing than state a number we cannot show you. If your audit needs those figures, ask and they will be sent with supporting documents.
Questions About The Plant And Quality
Can I visit the factory
Yes. Send a date on WhatsApp or by email and a visit to the Zengcheng plant can be arranged.
What quality certifications do you hold
ISO 9001:2015 for quality, ISO 14001:2015 for environment and ISO 45001:2018 for occupational health and safety. All three certificates are shown above and can be downloaded as PDF.
How are moulded parts checked
Against the drawing in the measuring room using a profile projector microscope and gauges, rather than against a golden sample.
How are wound components tested
On the electrical test bench. Inductance and resistance are measured with an LCR meter and Kelvin clips, and winding and insulation checks are run on a second test set.
Do you make your own tooling
Yes. Mould design and tool making are in-house, on the wire cut EDM and CNC machines shown above.
Are your products RoHS compliant
Yes. All products from CB Magnetics are RoHS compliant.
