Wood branding iron: which iron to choose for your logo?

Wood branding iron: which iron to choose for your logo?

To brand your logo on wood, the right iron depends on how many pieces you mark. For occasional marking, a brass block engraved with your logo, mounted on a rod and handle and heated with a flame, is all you need.

For series production (joinery, cabinetmaking, crates, boards), an electric branding iron gives the same mark from the first piece to the last. The most requested setup is a brass block for a design up to 45 mm on a 200 W electric iron.

Heated iron or electric iron: it all depends on volume

Heated iron (block on rod and handle) Electric branding iron
Use Occasional marking, one-off pieces, gifts Series production, workshop
Heating Flame: blowtorch, gas burner, forge Mains power, stable temperature
Consistency The iron cools with each mark and must be reheated Identical mark from one piece to the next
Budget The most economical Higher, quickly paid back on a series

The heated iron suits the woodworker who signs a few pieces of furniture a year, the craftsman marking one-off pieces, or anyone personalising a gift. The rod and handle keep your hands away from the heat.

The electric iron is the right choice as soon as you mark regularly: cutting boards, wine crates, toys, turned wood objects. The wattage depends on the size of the mark: the larger the engraved area, the more watts are needed to keep it at temperature. As a guide: a design up to 25 mm → 100 W, up to 45 mm → 200 W, up to 65 mm → 300 W. Except for plywood or MDF, do not go below 100 W.

Brass for wood, stainless steel for food

For wood, the design is engraved into a brass block. Brass conducts heat very well: it heats up quickly and spreads the heat evenly across the whole logo, giving a clean, even mark. Stainless steel also marks wood well, but it is mainly used for food branding irons (bread, buns, meat), as it is the right metal for food contact.

Hardwood, softwood: match the wattage

The wood species affects the setting more than any other factor.

  • Hardwoods (oak, beech, walnut, ash): they absorb more heat. Choose one step above the wattage recommended for your mark size: 200 W instead of 100 W, or 300 W for an area usually marked at 200 W.
  • Very soft woods (poplar, lime, balsa) and resinous woods (pine, fir): they burn quickly, and resin can run or blacken around the logo. An energy controller, available from 200 W, lets you lower the temperature of the electric iron.
  • Plywood and MDF: watch out for glues and binders, which can give off smoke.

In every case, make 2 or 3 test marks on an offcut of the same wood before marking the finished piece.

Your logo: size, lines, outlines rather than solid areas

  • Size: choose the maximum size of your design to suit the piece: 25 mm, 45 mm or 65 mm. 45 mm is the best-selling size, suited to boards, boxes and small furniture.
  • Lines: avoid large solid areas, which turn into black blocks on wood. Outlines and open lines mark much more cleanly.
  • Engraved in reverse: the block is engraved as a mirror image so the logo reads the right way on the wood.
  • Deep 3–4 mm engraving, standard at Charrier: material is cleared around the design, so only the logo touches the wood. The background and edges of the block leave far fewer marks, even on a slightly curved surface or a soft wood that gives under pressure.
  • Proof included: you approve the result before production, whatever the format of your file.

Who brands wood, and what for

  • Joiners and cabinetmakers: signature on furniture, drawers, doors, bespoke pieces.
  • Coopers and wine crates: estate brand, vintage.
  • Makers of cutting boards and utensils: brand logo in series.
  • Wood turners and wooden toy makers: small, discreet signature.
  • Firewood producers and merchants: marking logs and batches to identify origin or brand, directly on the raw wood.
  • Pallets and wooden packaging: identification and traceability (see our pallet marking page).
  • Hobbyists: personalised gifts, craft workshops.

The most common mistakes

  • Iron not powerful enough on hardwood: pale, uneven mark. Go up one wattage step.
  • Iron too hot on soft or resinous wood: burnt logo, black smudges, running resin. Use an energy controller.
  • Contact too long: the mark spreads and loses sharpness.
  • Pressing at an angle: one part of the logo marks harder than the other. Keep the iron flat.
  • Logo too detailed for its size: small letters fill in within the wood grain.
  • No test mark: every species reacts differently, always test on an offcut.

Frequently asked questions

Which branding iron should I choose to sign my furniture?
For a few pieces a year, a brass heated iron engraved with your logo. For regular production, a 200 W electric iron with a 45 mm design covers most needs.

What wattage for an electric branding iron?
It depends on the size of the design and the wood species: 100 W for a design up to 25 mm, 200 W up to 45 mm, 300 W up to 65 mm. On hardwood, go one step up (for example 200 W for a 25 mm design).

Can I brand softwood or resinous wood?
Yes, with an energy controller (from 200 W) to lower the temperature and avoid burning. Without one, you can unplug the iron and use a scrap board to bring its temperature down before marking.

Is the mark permanent?
Yes: the heat burns the wood surface, so the mark does not wear off. Deep sanding will fade it.

Can I brand firewood?
Yes. Our irons mark the raw wood of logs to identify a brand, an origin or a batch. On this irregular wood, choose a simple logo with thick lines and enough wattage. Always mark off the bark, on bare wood (the end of the log or a split face).

Can I use the same iron on wood and on food?
Yes, if it is stainless steel, which works for both. A brass block is for wood only.

What lead time for an iron with my logo?
⏱ Estimated lead time: 15 to 18 working days in total, proof and production included, excluding shipping. Fast-track and Rush options are available: contact us. For countries outside the EU, customs duties are not included.
