Plastic/Resin

Peel the paint or printing on the target surface to bring out the contrast with the color of the base material.

Conventional methods (like printing and stamping) require full plate changeovers when a design change occurs. With a laser marker, you can adjust layouts by simply changing the program.

(Example) Half cut

A laser marker can be used to easily process a cutting section. Physical cutters are conventionally used in these scenarios, but they're difficult to adjust and time-consuming to change. Moreover, physical blades must be replaced often (incurring hard costs) and there's a risk that the blade will come loose and get left in the product.

Irradiate a plastic target with a laser to develop a color in the target itself.

（示例）LSI上的广阔区域标记

By using laser radiation to develop a color instead of engraving the plastic, damage from marking the target is minimized.

Use the heat of laser radiation to weld and join plastic parts.

(Example) Welding of transparent plastic and colored plastic

Traditional welding can cause vibration which may affect the product or produce burrs. Since laser welding does not make contact with products, it won't damage them or produce burrs.

当基本材料被激光照射时，由于辐射的热效应，在材料内部产生气泡。气体气泡包含在基本材料的表面层中，并产生白色的肿胀。当基本材料具有深色时，肿胀是高度可见的，通常比标记之前更轻。

When a base material absorbs the laser energy, the thermal effect increases the molecular density.
The molecules are condensed and the color becomes darker.

When an area is continuously irradiated by laser light, macromolecules of the element around the base material are carbonized and turn black.

The “pigment” elements in a base material typically contain metallic ions. Laser radiation changes the crystal structure of the ions and the hydration level in the crystal. Consequently, the composition of the element itself changes chemically, resulting in color development due to the increased intensity of the pigment.

激光照射根据目标塑料的颜色产生高度可见的黑色 /白色标记。结果，激光标记提供了无法删除的印刷表面。

Laser markers can easily create clear, white marks on epoxy plastics. They're great replacements for stamps, labels and printers. The highly-visible, print-like markings do not disappear like ink.
