Tooling Cost and Mould Ownership for Lighting Housings

Tooling is the single line on a housing quotation that varies most between one supplier and the next, and it is the line buyers read least carefully. There are really only two cases, and knowing which one your part falls into tells you most of what the quotation will say.

Case one: the part runs on existing tooling

If your housing matches a section or a body family that has already been tooled — a 22 × 25 mm magnetic track profile, a standard 595 × 595 mm panel frame, an established spotlight body — then no new tool has to be made and there is no tooling charge. The part is quoted as a unit price and a lead time.

This is the cheapest and fastest route into production, and it is a large part of why ranges that are already tooled are worth designing around. Standard cross-sections and common cut-outs are not a compromise; for most repeat programmes they are the sensible engineering choice.

Case two: the part needs its own mould or die

If the geometry is genuinely new, a tool has to be made, and it is quoted separately as a one-off cost. Two things follow.

First, the tool itself has a lead time. Mould making and first-article approval typically add around 15 to 20 days before production can start, on top of sampling.

Second — and this is the part that matters commercially — the tool is the subject of a contract term, not an invoice line. If the buyer pays for it, the mould is dedicated to that buyer for the life of the project. If it is not paid for by the buyer, the supplier holds it, and the buyer's position is different.

The ownership term is what decides whether a second source is possible

This is where tooling stops being a technical question. A second source can only be built on a tool that is yours to move. If the tooling is held by another supplier and does not belong to you, no second source can be built on it — and a supplier who quotes as though one could is not being straight with you.

The practical consequence is that tooling ownership should be settled before you need a second source, not during the emergency that made you want one. It is a contract term you can negotiate calmly at the start of a project and cannot negotiate at all when a line has stopped.

For parts that run on existing tooling this problem does not arise at all, which is one more reason to start there.

Should tooling be amortised into the unit price?

Either arrangement is normal. What matters is that it is written down. A one-off tooling charge and a lower unit price, or no tooling charge and a unit price that carries it, are both defensible — but an arrangement that exists only in a conversation is not, because it cannot be checked later and it cannot be transferred between suppliers.

Where JUNKE sits

Existing housing series and standard sections carry no tooling charge. New moulds and dies are quoted separately as a one-off cost, and where the buyer pays for the tooling the mould is dedicated to that buyer for the life of the project. Where a requirement falls outside the tooling, finishing or IP sealing capability available through our supply chain, we say so at enquiry stage rather than quoting and adjusting afterwards.

Frequently asked questions

Do you charge for tooling, and who owns it?

New moulds and dies are quoted separately as a one-off tooling cost. Where the buyer pays for the tooling, the mould is dedicated to that buyer for the life of the project. Existing housing series require no tooling charge at all.

Which lighting housing parts need no new tooling?

Parts that run on an already-tooled section or body family — a 22 × 25 mm magnetic track profile, a standard panel frame size, or an established spotlight body. These are quoted as unit price and lead time with no tooling charge.

How long does new tooling add to a project?

Mould making and first-article approval typically add around 15 to 20 days on top of sampling, before production can begin.
