Lasers in Industry

Supplier: Laser Central
04 September, 2009

Many years in development, laser processing of metals is now considered essential in industry. Laser Central is unique in Australia to offer 3D tubular laser processing as well as flatbed laser cutting and metal pressing.

A Brief History of Lasers
The word laser means “Light Amplification by Stimulated Emission of Radiation”. Einstein first theorised about lasers in 1917 with laboratories demonstrating the concept in 1935.  But it was not until 1957 that the lasers were considered viable.  General consumer awareness of lasers began with barcode scanners in the early 1970s followed by the famous compact disk (CD) boom of the 1980s.  Industrial use for cutting metals started in the 1970s using what is known as carbon dioxide (CO2) lasers.  Today, the CO2 laser is still the work horse of industrial laser cutting.  Laser power for use in metal cutting has increased from 1500 Watts in the early 1990s to today’s 6000 Watts.
 
Advantages of Laser Processing of Metals
Laser cutting offers high accuracy and repeatability, low heat affected zone around the cut and the ability to process a wide range of materials including timber, plastic, mild steels, hardened steels, stainless steels, aluminium alloys, titanium, nickel alloys and more.  Waste material is minimised through efficient part layout.  This, combined with fast turn around and access to small batch sizes, provides industry with superior advantages compared to alternative processes.
 
New horizons: Tubular Laser Cutting
One application of industrial lasers to come to fruition in recent times has been tubular laser cutting.  This enables the processing of tubular products in 3D including rectangular hollow sections, pipe, angle and universal beams.  The ability to process such material in 3D allows significant time (and hence cost) savings in downstream processes such as weld preparation of heavy pipe, slotting and drilling, complex contouring and mitre cutting.  This allows workshops to utilise their specialist labour for value adding work rather than focusing on mundane processes.  Laser processing of tubular materials saves assembly hours and lets clients focus on being lean in their manufacturing endeavours.
 
Tubular Laser Cutting in Action
Laser Central has had several years experience with 3D tubular laser processing, being the first to install such a machine in Australia.  In that time, we have been involved in range of exciting projects including: structural frames for V8 Supercar chassis; truss systems for coal loading facilities; structural steel pre-assemblies for infrastructure projects; and OEM parts supply for vehicle components.  Every client that has taken advantage of this technology has saved cost and made profit.  With the limitless possibilities for design and labour saving, 3D processing of tubular products means competitive advantage for clients.
 
Laser Central: Exceeding expectations
Laser Central began providing clients with solutions over ten years ago.  Key to this has been investing in leading edge technology such as 3D tubular laser processing and laser measured press equipment. With ISO 9000 certification, proactive continuous improvement and a lean manufacturing program, Laser Central is unique amongst its competitors.  Through strong customer relationships, Laser Central aims to raise the profits of clients through effective value adding.  If you have any questions about how Laser Central can provide competitive advantage to your company, please contact us.
