Robust Laser Cutting In Australia

Laser cutting is a process used to cut through materials using a high-power laser beam, focused on the material to be cut. The laser beam turns into plasma, which then melts or burns the material; thus, it can easily pass through via an airstream. The result is a part with a smooth cut.

Moreover, it is possible to combine laser cutting with other manufacturing processes for advanced operations.

Zeal 3D is an ISO 9001-2015 certified company offering efficient laser cutting in Melbourne and other places across Australia. With years of experience in the industry, we provide quality parts with a keen focus on 100% customer satisfaction. With a modern in-house setup of equipment, we can offer laser cutting for plastics and metals.

How does laser cutting work?

The laser beam is directed to the material via mirrors and lenses. The power of the laser beam can be adjusted as per the cutting requirement. Once this adjustable beam reaches a material, it deflects off its surface and then it passes through an airstream, which blows away the cut part from the rest of the block.

The overall working laser cutting for metal or any other material is easy. First, the laser beam melts the material through a process called sublimation. As soon as this happens, air blows away the material to form a molten ribbon-shaped flow used for ejecting off the cut part from its block.

When it comes to CO2 laser metal cutting, it is performed at atmospheric pressure, which means the metal to be cut, along with other material in its vicinity, gets vacuumed. These materials are easy to re-use for laser cutting after cooling down. In addition, the laser beam is created in a tube filled with CO2 gas.

Whether you need aluminium laser cutting or plastic laser cutting, Zeal has got you covered. Our team of engineers strives to offer efficient, reliable and cost-effective services.

Popular varieties of laser cutting services

Zeal offers you a comprehensive range of plastic, metals and stainless steel laser cutting services. Below are the top three popular laser cutting technologies that are widely used across industries:

Gas lasers/C02 laser cutters: These lasers use CO2 gas that gets converted into a single carbon-dioxide laser beam. These bigger spot sizes laser cut wider kerfs and no heat-affected zone.

Crystal laser cutters: These lasers use a combination of potassium, fluorine and other gases. This argon laser cutter offers the best resolution, producing high-precision parts for various industries. It can even cut through metals.

Fibre laser cutters: With a high-quality beam of light, these lasers effectively cut parts made from all kinds of materials. They offer fast cutting speed and produce highly complex components with low kerf loss.

Laser Cutting Methods

Laser cutting can be done in a variety of methods, with different types of lasers being used to cut a wide range of materials. Some of the most popular laser cutting methods are given below.

Vaporization: In vaporization cutting, a concentrated beam heats the material's surface to flashpoint, creating a keyhole. The keyhole creates a rapid increase in absorptive, which widens the hole rapidly. As the hole deepens and the material heats, the vapor produced erodes the molten walls, causing them to eject and widening the hole even further. This process is commonly used to cut non-melting materials like plastics, fabrics, wood, paper, foam, carbon, and thermoset polymers.

Melting: When compared to vaporization technique, this melting method requires less energy to implement the laser cutting process. The required energy is about a tenth of that required for vaporizing laser cuts, where the laser beam heats the substance, causing it to melt in this process.

As the material melts, a stream of gas emerges from the coaxial nozzle with the laser beam, ejecting it from the cut. Since the energy requirement for this method is comparatively low, it is used for cutting active or non-oxidizing metals such as titanium, stainless steel, and aluminum alloys.

Thermal Stress Fractures: A small kerf is inserted into the material using a laser at depths of roughly one-third its thickness. After that, the laser is employed to create localized strains. This is accomplished by heating a tiny area and causing compressive pressures to form around it. The area somewhat cools after traveling through the laser beam, causing thermal stresses. Such thermal stress fractures are commonly used to cut brittle or fragile materials like glass and ceramics.

Laser Compatible Materials

Some of the most common materials that are well suited for the Laser Cutting process are given below.

Plastic: Plastic and acrylic elements are commonly used for producing jewelry, ornaments, wall art, and much more. The following list includes plastic materials that can be laser cut.

Acrylic
ABS (Acrylonitrile Butadiene Styrene)
Delrin
HDPE (High density polyethylene)
Kapton tape Mylar (polyester)
PETG (polyethylene terephthalate glycol)
Polyethylene (PE)
Polypropylene (PP)
Styrene plastic

Metal: Intricate designs can be produced in a variety of metals with great efficiency and accuracy using metal laser cutting. This accuracy results from the laser melting, burning, and vaporizing the metal instead of stamping or cutting through it. The following list includes several metal materials that can be laser cut.

Aluminum
Mild steel
Stainless steel

Advantages of laser cutting

It enables you to produce difficult or nearly impossible shapes to create via other methods.
Parts produced by laser cutting are precise and accurate.
Since laser cutting requires less raw material, it is cost-effective as well.
The workflow used for this process makes it ideal for mass production.
Since laser cutting results in reduced wastage, companies using this technology can save considerable money on manufacturing costs.

Tolerances and Surface Finish:

The most commonly used parameter for determining surface roughness is the standard roughness (Rz). Usually, the positioning accuracy of new laser cutters is 10 micrometers, with a repeatability of 5 micrometers.

Standard roughness (Rz) increases as sheet thickness rises, but reduces as the cutting speed and laser power increase. When cutting low carbon steel with an 800 W laser, the typical standard roughness (Rz) is 10 m for 1 mm sheet thickness, 20 m for 3 mm, and 25 m for 6 mm sheet thickness.

The laser cutting process is capable of maintaining very tight tolerances, typically as low as 0.001 inch. Tolerance possibilities are heavily influenced by part geometry and the machine's mechanical soundness. The laser beam cutting method produces a surface polish that can range from 125 (0.003mm) to 250 (0.06mm) micro-inches.

Laser cutting applications

Automobile Industry: Car parts like windshield wiper blades and interior panels can be made using laser cutting.
Industrial manufacturing: Laser cutters make everything from furniture, lighting fixtures and door frames to cabinets, signs and showpieces.
Aerospace: Air rocket engines, aeroplane components and satellite structures can also be made using this technology.
Hospitals: Modern operating rooms use lasers that can be adjusted into different sizes and shapes for various surgeries.
Mining: Laser cutters help produce roof support structures at mines.

Machine Configurations

The three distinct configurations for laser cutting machines are Moving material, Hybrid, and Flying optics, which defines how the laser beam moves or is moved across the material.

Moving Material: The material is affixed to a moveable cutting surface on this type of laser cutting machine, which has a stationary laser beam. To make the required cuts, the workpiece is manually moved all around the stationary beam. This setup provides for a steady and uniform standoff distance while using fewer optical components.

Hybrid: Hybrid laser cutting machines combine the benefits of both moving material and flying optics laser cutting machines. Hybrid lasers have a table that travels along one axis (typically the X-axis) while the head moves along a shorter axis (the Y-axis). In comparison to flying optical machines, this can result in a lower power outage in the delivery system and better capacity per watt.

Flying Optics: A moving laser cutter head and a fixed workpiece are featured in flying optics laser cutting devices. To make the required cuts, the cutting head moves the laser beam in the X- and Y-axes across the fixed workpiece. Flying optics machines are versatile enough to cut materials of various thicknesses and sizes while also allowing for speedier processing times.
