Processed Copper, Made to Your Drawing

Inside every LV panel, the current path is copper — and the pieces that carry it rarely match a catalogue. Connection points move, hole patterns change, and the part has to fit your breaker, your bar and your panel layout. This page covers copper parts that are processed to order: the drawing decides the shape, the material and the finish.

Production runs through our manufacturing network in Liushi — stamping presses for flat and formed pieces, CNC centres for drilled, tapped and milled geometry. Material is T2 copper at 99.9% purity or above, and tin or silver plating thickness is stated in microns (µm) in the quotation, so what you approve is what gets made.

One honest limit, stated up front: we do not sell standard straight busbar lengths. Plain bar is heavy, its price moves daily, and it is cut locally on demand in your market — it almost never makes sense to import. The value is in the processed part: cut, drilled, tapped, bent and plated to your drawing.

Who buys this

Panel builders who need connector blocks and connection plates that match their own panel design
Switchgear workshops replacing worn or obsolete copper parts re-made from a sample
Project contractors ordering flexible connections and terminals to a project specification
Consolidating buyers — copper parts travel in the same container as enclosures and sourced components

Specification & Quotation

Specification — and What to Send for a Quotation

Only the claims we make anywhere on this site: material, finish and tolerances are confirmed in writing in your quotation, before production.

Production basis	Your drawing (PDF / DWG / STEP) or physical sample — processed to order only
Material	T2 copper, purity ≥ 99.9% — grade confirmed in writing per order
Processes	Cutting, drilling, tapping, bending, stamping, CNC milling & turning
Surface finish	Natural, tin plated, silver plated — thickness in µm confirmed at quotation
Typical parts	Connector blocks, terminals, flexible braided connections, bent connection plates, neutral & earth connection pieces
Please note	Processed parts only — standard straight busbar lengths are not sold; plain bar is heavy, price-volatile and cut locally in your market

What to send for a quotation

Drawing file (PDF / DWG / STEP) — or clear photos + dimensions, or the sample by courier
Material & thickness of each piece
Plating — natural / tin / silver, and µm if your standard fixes it

From Drawing to Shipment — How Your Order Runs

STEP 1

Drawing

Your drawing, sample or list received — material, finish and details confirmed in writing before anything is made.

STEP 2

Sample & Quotation

Price and lead time quoted openly; a sample is made first wherever tooling is involved, and production follows your approved sample.

STEP 3

Inspection

Production followed in Liushi; finished goods checked against the drawing, with photos & video shared with you before shipment.

STEP 4

Shipment

Export packing, then consolidation into one container to your port — together with your other lines from this site.
