Equipment features

Localized repair welding for molds

The HODA HD-WY mold laser welding machine repairs porosity, local cracks, chipped edges and worn areas on molds. The laser concentrates heat on the defect while filler wire is fused to the base material; the rebuilt area is then finished by grinding, EDM or machining to restore the surface and size.

Build-Up on the Defect Only

Filler wire fused layer by layer on porosity, chips and wear
Weld points planned around the defect shape and finishing allowance

Microscope Positioning

Micro observation of the defect edge, wire tip and target position
Suitable for mold edges and small repair areas

3D Manual Worktable

Worktable moves the repair area into the viewing and welding position
Stable station work for small and medium molds

Adjustable Pulse & Spot

Pulse width 0.2–20 ms; frequency 0.5–20 Hz; spot 0.2–2 mm
Parameter space for different repair areas and materials

Fine Filler Wire

0.2–0.4 mm wire for 200 W and 300 W; 0.2–0.5 mm for 400 W
Wire material selected by the mold steel and duty

Repair samples

Mold repair samples

Localized repair on mold surfaces — the defect, the deposited material and the finished area are assessed stage by stage.

Laser welding samples: ejector pins, inserts, flanges and machined blocks — **Sample workpieces** Ejector pins, inserts, flanges and machined blocks repaired as samples.

Repair depth and weld results depend on the base material, filler wire and finishing method.

Applications

Where the mold welder fits

For mold makers and maintenance shops that restore repairable areas instead of replacing tools.

Plastic Molds & CavitiesBuild-up on local defects, cavity edges and related surfaces, finished to the molding face requirement.

Die-Casting & Casting MoldsFiller added to repairable wear or chipped areas, with the process matched to the mold material.

Stamping & Forging ToolsLocal build-up on repairable areas, watching geometry and working conditions after repair.

In-Process ReworkMachining defects handled during production and maintenance, followed by grinding or EDM.

If the mold is too large or heavy for the standard station, compare the Large Mold Laser Welding Machine.

Motion forms are series configuration options and are not all installed at once. Repair results follow the base material, filler and finishing method — the defect and mold material are confirmed before the process is set.

Materials

Mold steels including S136, SKD-11, NAK80, 718, 738, P20 and W302, plus carbon steel, common alloy steel and stainless steel. Heat-treatment state, service history and defect condition shape the repair method.

Configuration & support

From defect to finished surface

Power options200 / 300 / 400 W by defect size and detail.

Worktable & motion3D manual table; lifting, rotation and horizontal movement by configuration.

Wire selectionFiller matched to the mold steel, heat treatment and duty.

Finishing planGrinding, EDM or machining arranged after welding.
