Laser cutting service advantages

• Fast delivery

Quickly produce high-precision parts within 10 days with the new laser cutting machine.

• Customized Surface Treatment

The laser cutting parts can be post-processed according to customer requirements, including spraying, heat treatment and other processes.

• Quality Control

Our Quality Assurance department implements a strict quality assurance process.

• Precision

Various tolerance options available in accordance with ISO 2768 (standard, fine) and ISO 286 (classes 8, 7, 6).

• Material selection

Choose from a variety of different metal sheets, varying in strength, conductivity, weight, and corrosion resistance.

Laser Cut Finish Options

Milling

Choose this finish option for the fastest delivery. Parts will leave visible tooling marks and may have sharp edges and burrs that can be removed upon customer request.

Spraying service

• Anodizing: Hardcoat and Color (Black Hardcoat, Black, Blue, Gold, Grey Hardcoat, Green, Natural Hardcoat, Natural, Orange, Red)
• Passivation

Surface treatment

• Polishing / Electropolishing
• Surface hardening
• Powder coating: This process applies powder coating to the part, which is then baked in a high temperature oven. The result is a hard outer layer that resists wear and corrosion, and is more durable than standard painting methods. Available in a variety of different colors to create the desired look.

Heat treatment

• Tempered
• Annealing

Custom made

Other processes and surface treatments are available upon customer request.

What is a laser?

Basic Principles of Laser Cutting

CNC laser cutting is a computer-controlled machining process that uses a high-density beam of light to cut parts from sheet metal workpieces. This process is done under the guidance of a computer according to a pre-uploaded 2D model. The laser cutting process is known for its cost-effectiveness and high precision.

Laser cutter

CO2 lasers are typically used for standard production purposes (such as cutting thinner metals)

Nd and Nd:Yag lasers are more powerful and used to cut thicker metal sheets, but are more expensive than CO2 lasers

Tolerance

Standard tolerances for most CNC laser cutters are between 0.1 and 0.2 mm, depending on size and requirements. But the tolerance level can be adjusted according to customer requirements.

Size limit

Any size; the maximum thickness of the aluminum plate does not exceed 6 mm.
