An industrial automation parts supplier built on verified originals, testing and long-term partnerships.
Muchen supplies original automation parts — PLCs, HMIs, servo drives, power supplies and protection devices — to panel builders, integrators and distributors. Our strength is range: 2,000+ part numbers across 22 brand lines, including obsolete and discontinued series that normal channels no longer carry. Send a model list; if the part still exists, we will find it — and if it is gone, we will tell you straight.
We keep a simple promise: original parts, verified quality and communication you can rely on. Every quotation is answered within 12 hours, and every shipment ships with full documentation.
Get a QuoteS7-300, S5, older Modicon and legacy HMI panels are the models we are asked for most — we search our supplier network model by model, not just the catalogue.
PLCs, HMIs, servo drives, power supplies, breakers and sensors — several brands on one purchase order, consolidated into one shipment.
We check series, revision and suffix against your list before quoting, so you never receive a near-match that will not fit the panel.
If a part is gone, we say so within 12 hours and propose an alternative — instead of taking the order and stalling.
Every order is checked by our sourcing team before dispatch — and you are welcome to verify remotely at any step: clear photos, live video calls or third-party inspection (SGS / BV).
Serial numbers, packaging and brand markings are checked when parts arrive.
Every item is matched against your exact model list before quotation and packing.
See the actual parts before they ship — clear photos of each item, or a live video call on request.
