Surface Annealing-title

Surface Annealing

A laser processing method which causes an oxidation process underneath the material surface to achieve a contrasting  mark visually, resulting in a colour change on the metal surface.

 

PROFESSIONAL LASER SURFACE ANNEALING SERVICES IN SINGAPORE

Laser annealing, unlike laser engraving or etching, uses low-powered laser beam to heat the metal where oxygen is diffused  below the surface. The metal oxidized internally and resulted in a colour change on the metal surface once cooled off. On  the other hand, the laser engraving or etching melts or removes the material to create a contrast with depth. Laser  annealing is only applicable on metal.

Therefore, laser annealing is a widely used application due to its capability to maintain a product’s felt experience, without  disrupting, damaging or altering the strength of the material. Nothing is removed from the surface being heated in  annealing. The heat of the laser creates an oxidation process that leaves a permanent mark that is great for  keeping products such as medical devices eternally traced.

Fun fact: Due to the intensity of chemical reaction from laser power or heat produced, metal types such as ferrous metals  and titanium can display different colours depending to the temperature at the surface of the metal.

 

BENEFITS OF LASER SURFACE ANNEALING

✓ Annealing marking causes no disruption to the material and it has the advantage of not altering the strength or  damaging the surface of the material.

✓ It gives your product a personal touch with customized design.

✓ It enables precision marking on product’s parts with their reference numbers and other important manufacturing  information.

✓ It is permanent and very resistant to abrasion.

✓ It is reliable, efficient and cost-effective process that delivers a much higher quality and productive (can produce  individual, small area and large area at production) than the traditional technique of engraving such as chisel using  tooling pins, stamping and moulding methods.

✓ It is a no direct contact, safe and environmentally-friendly engraving technique. It requires no chemical, inks and  tooling such as bit heads. Thus, there is minimal wear and tear to the engraving equipment during the engraving  process.

✓ The laser technology makes it possible to achieve the finest motifs with maximum precision. Virtually everything  that can be drawn can be marked using a laser.
