Meaning
Additive restoration techniques use a laser beam to melt metal powder onto worn or damaged tool surfaces. Precision toolrooms utilize laser cladding refurbishing to repair worn parting lines, eroded gates, and damaged injection mold inserts. This repair process achieves a high-strength metallurgical bond with minimal heat input, preventing tool distortion.
Process Mechanism
Laser beams melt a small pool on the substrate surface while a metal alloy powder is simultaneously fed into the melt zone. Executing laser cladding refurbishing deposits a dense, high-quality layer of tool steel that matches the original tool hardness. This precision deposition is highly localized, which minimizes the heat-affected zone and protects the geometry of the surrounding mold cavity.
Material Restoration
Mold components restored with this method exhibit wear resistance comparable to the original steel. Utilizing laser cladding refurbishing allows technicians to rebuild fine details. The parts are subsequently machined back to drawing specifications.
Cost Efficiency
Rebuilding damaged tools with additive processes is much faster and less expensive than machining a completely new insert. Employing laser cladding refurbishing minimizes toolroom downtime and avoids the high costs of raw tool steel blocks. This is a critical advantage for high-volume molders who must return damaged multi-cavity tools to production as quickly as possible to avoid shipping penalties.
