Process overview · Drawing A
Nine operations, drawn on the part
Buyers rarely need "a machine". They need one station. Select a number to see the machines that perform it.
Machines
Configured by station, not bought from a catalogue

What we are asked about most
Commutator turning precision
Turning is the process our engineers name as their specialty. Runout and surface figures will be published from test reports, not claimed.
Custom builds and urgent orders
Machines are built to the armature drawing. Tooling for additional models and expedited delivery are quoted per project.
Installation in Southeast Asia
Sea freight from Shenzhen, export crating, recorded FAT, then SAT and operator training at your plant.
Projects
Delivered lines

A second armature line for a power-tool motor plant in northern Vietnam
Nine stations replacing a part-manual line, commissioned in eleven weeks. First-pass yield at final test rose from 94.2% to 98.7%.
Factory · Dongguan, Guangdong
From drawing to acceptance run, everything happens in our own plant
Machining, assembly, commissioning and spare parts sit in one site. Before shipment every machine runs on the customer's own cores, commutators and wire, and the run is recorded.
