Clean the injection mould without disassembly, abrasives or water — with a laser

The 1500 W fibre laser removes burnt resin, oxides and release agents directly from the mould through selective ablation — without disassembly, without abrasives and without scratching the working surface.

The mould is not idle because it is dirty. It is idle because the cleaning method requires disassembly, transport and reassembly — and every hour the station is stopped is paid for in lost production.

For a maintenance manager or a production head in an injection department, the real question is not which cleaning machine do I buy, but how do I stop the line less every time the mould needs cleaning. And the usual method seems logical: stop, remove the mould, clean it with brushes, abrasives or solvents, reassemble it, restart.

The problem is that this very cycle — disassembly, transport, reassembly — consumes most of the time. The dirt itself does not keep the machine idle; the cleaning method does. On top of that comes the risk that wire brushes and abrasives scratch the cavity and ruin its fine texture — the very surface on which the quality of the moulded part depends.

Where time and money are actually lost

An injection mould is an expensive, precise tool. Every classic cleaning means: hours of downtime for disassembly and reassembly, the risk of scratching from abrasive methods, consumables (abrasives, solvents), and in the case of wet cleaning, the risk of corrosion. And if the deposits (burnt resin, oxides, release agents) remain partly, moulding defects appear — marks, burns, release problems — which are paid for in scrap.

What laser cleaning changes

The laser shifts the problem from how do I clean better by scrubbing to how do I stop disassembling at all. Cleaning is done in-situ, directly on the injection machine, and the action is not mechanical but optical: the layer of contaminant absorbs the energy and vaporises, the mould steel reflects it and remains untouched.

In concrete terms, that means three things a decision-maker feels directly: the disassembly and reassembly time disappears, the scratching risk that shortens the mould’s life disappears, and the recurring consumables disappear. For the operator, it means cleaner work, without physical effort and without chemicals.

Why the laser does not ruin the mould

This is the technical question the maintenance manager always asks, and rightly so. The answer lies in the mechanism: at the 1080 nm wavelength, the energy is absorbed selectively by the layer of contaminant, not by the metal substrate. There is no scrubbing, no abrasion and no mechanical transfer into the working surface. That is why the finish and texture of the cavity remain intact — something that brush or abrasive-media methods cannot guarantee.

Below you will find the exact parameters an engineer can verify, the recommended equipment and what this change means for downtime and for the life of the mould. The best proof, however, remains a single one: a demonstration on an old mould of yours, so you can see the result before you decide.

Consequences

What classic mould cleaning costs you

  • ! Long production stops for disassembling and reassembling the mould
  • ! Scratches and wear from wire brushes or abrasive methods
  • ! Loss of the texture and fine finish of the cavity
  • ! Moulding defects from remaining deposits (burns, marks, release)
  • ! Recurring costs for abrasives, solvents and consumables
  • ! Risk of corrosion where wet cleaning is used

The solution

How the fibre laser cleans — selective ablation, not scrubbing

The laser does not scrub or grind the surface: a fibre beam is absorbed by the layer of contaminant (burnt resin, oxides, release agents), which vaporises, while the mould steel reflects it and remains untouched. That is why cleaning is done directly on the machine, without disassembly and without the scratching risk of abrasive methods.

Parameter Value Role
Laser power 1500 W (fibre laser) Removes hard contaminants: burnt resin, oxides, release agents
Wavelength 1080 ±10 nm Absorbed by the contaminant, reflected by the mould steel
Cleaning speed 8–40 m²/h Fast cleaning, directly on the production line
Operating mode continuous or modulated Fine adjustment to the type of deposit
Working medium no water, abrasives or solvents Zero residue, zero scratching risk
Cooling air No water circuit — mobile in the hall, right at the mould
  • In-situ laser cleaning removes burnt resin, oxides and release agents without disassembling the mould, without abrasives and without water.
  • The fibre beam at 1080 nm is absorbed by the layer of contaminant, not by the mould steel — the surface and texture of the cavity are not scratched.
  • The cleaning speed is 8–40 m²/h, adjustable according to the type and thickness of the deposit.
  • The process is dry: no water, no solvents and no abrasives, so no rinse residue and no risk of corrosion.
  • Continuous or modulated operation allows fine adjustment between light deposits and hard, burnt layers.

ROI and risk

Less downtime, a protected mould, no consumables

  • At your line's stoppage cost, every in-situ cleaning recovers the hours lost to disassembling and reassembling the mould
  • No abrasives and no wire brushes — eliminate the scratching risk that shortens the mould's life
  • No consumables (abrasives, solvents, blasting media) — the cost per cycle drops practically to electricity
  • A dry process — no risk of corrosion and no rinse residue before restart
  • Risk-free trial: we offer a demonstration on an old mould of yours, before any decision

Frequently asked questions

What we get asked most

Can I clean the mould without removing it from the injection machine? +
Yes. Laser cleaning is done in-situ — the beam reaches the cavity directly on the machine, without disassembling and reassembling the mould. This eliminates the very step that generates the most downtime in the classic method.
Does the laser scratch or damage the surface of the mould? +
No, by its very mechanism. The fibre laser at 1080 nm acts through selective ablation: the energy is absorbed by the layer of contaminant and vaporises it, while the mould steel reflects it. Unlike wire brushes or abrasive methods, the surface and texture of the cavity are not touched.
What contaminants does it remove from the mould? +
Burnt (carbonised) resin, oxides, deposits of release agents, gas traces and process residues. The continuous or modulated operating mode allows adjustment between light deposits and hard layers.
How fast does it clean? +
The cleaning speed is 8–40 m²/h, depending on the type and thickness of the deposit. For a mould, that usually means minutes, not hours — and without the extra time for disassembly and reassembly.
Does it use water, solvents or abrasives? +
None. It is a fully dry process: no water, no solvents, no abrasive media. No rinse residue remains and there is no risk of corrosion, so the mould can quickly return to production.
How much does it cost and can it be financed? +
The TIPORA Laser 1500W has a list price and can be purchased directly, through GRENKE leasing or via the AUTONOM programme (rent-to-buy, with 100% of the rent deducted from the price). Ask for a demonstration for a concrete estimate on your application.
In which industries is laser mould cleaning used? +
In plastics and rubber injection, at automotive suppliers (Tier 1 and 2), in packaging and PET, appliances, electronics and in mould shops and toolmaking — anywhere an expensive mould must be cleaned often, without being disassembled or damaged.
