We make extrusion dies for aluminium profiles

How it goes

1. H13 steel blankA blank of the required thickness, with machining allowance, is cut from a forged bar of H13 hot work tool steel.
2. TurningA CNC lathe machines the outer diameter, faces, chamfers and the fit for the die ring.
3. CNC millingA machining centre cuts the ports, pockets and bridges of a hollow die and the holes for dowels and bolts.
4. Vacuum hardeningThe die is hardened in a vacuum furnace and tempered several times, so the steel reaches working hardness without scale or distortion.
5. Wire EDMThe die opening is cut along the profile contour by wire EDM: accurate walls and sharp corners without stressing the steel.
6. Sinker EDMGraphite or copper electrodes sink the pockets, steps and bearings that a milling cutter cannot make.
7. Bearing polishingThe bearings are polished by hand: the profile surface and the die life depend on their finish.
8. NitridingIn a pit furnace the die surface is enriched with nitrogen: a hard layer protects the bearings from wear.
9. InspectionBefore shipment we check the opening and bearing dimensions, hardness and marking, photograph the die and send you a report.
10. PackingThe die is coated with corrosion inhibitor, wrapped in film, packed into a wooden crate and weighed, and the shipping documents are prepared.

We collect the crate with the die at our production site and take it to the airport cargo terminal.

What we do

• We collect the finished crate at our production site
• We check marking and weight against the documents
• Our agent in China handles the dispatch
• We take it to the airport cargo terminal

How it goes

1. Cargo terminal in ChinaThe cargo is handed over to the terminal, weighed and cleared for export.
2. Cargo planeThe die flies to Moscow. Air freight is much faster than sea or rail.
3. Arrival in MoscowThe plane lands in Moscow; the cargo is received and moved to a bonded warehouse.

Customs clearance is done by our own declarant. Duty and VAT are already in the quoted price.

What we do

• Our own declarant files the declaration
• Duty and VAT are already in the quoted price
• The cargo stays at the bonded warehouse until release

How it goes

1. Delivery to your plantAfter release we deliver the die to your plant. You can also collect it from the bonded warehouse.
2. Your plantThe die arrives with VAT and full closing documents from a Russian legal entity.
