Laser Mould Cleaning
Injection moulds and die casting tools accumulate mould release agents, polymer residues, and contamination with every production cycle. Traditional cleaning methods — abrasive blasting, ultrasonic cleaning, chemical cleaning — often require mould removal from the press, risk surface damage, and introduce downtime. Laser cleaning can be performed in-situ or offline and removes contamination without affecting the polished tool surface.
Mould Cleaning Applications
Injection mould tools
Plastic injection moulds fouled with mould release agent, degraded polymer, and gate residue. Laser cleaning is performed without removing the mould from the press in many cases.
Rubber moulding dies
Rubber mould tools accumulate release compound and rubber flash. Laser ablation removes these without polishing-grade abrasive contact.
Die casting tools
Aluminium and zinc die casting tooling. Laser removes lubricant residues and die soldering deposits without dimensional risk to the tool surface.
Press and forming tools
Stamping and forming dies cleaned of lubrication residue, metal transfer deposits, and surface contamination without regrinding.
Extrusion dies
Plastic and rubber extrusion die inserts and die faces. Polymer degradation deposits removed from fine features without dimensional impact.
Conformal coating removal
Selective removal of conformal coatings from mould tool areas requiring repair or modification, without disturbing adjacent areas.
Why Pulsed Laser for Mould Cleaning
Mould cleaning demands substrate safety as the primary criterion. Tool steel moulds are expensive and dimensionally critical — any surface modification would render the tool unusable or require re-polishing. Pulsed laser systems (ARC series) are the correct choice for mould cleaning because the short pulse duration limits heat transfer to the substrate. The contamination is ablated before the tool surface absorbs significant energy.
CW laser systems should NOT be used for mould cleaning. Their continuous energy output delivers too much heat to the substrate and risks surface modification, hardness changes, or dimensional alteration of the tool.
