Medical stainless steel is used in the manufacture of medical equipment. It has specific properties that are crucial in the creation these finely tuned tools.
During construction of the equipment the tools must be marked. Serial numbers and identification symbols are often applied to distinguish the tools. These markings are essential for the user of the tool to tell them apart.
However Its important not to tamper with the construction of the steel when marking the equipment. So In order to create highly accurate, clean and precise marks on a medical implement, a laser etching machine is used to create the markings that will distinguish the tools.
The laser used by the etching machine indents the surface of the steel just enough to create a non-erosive image, but not so much as to alter its properties. Allowing for the necessary markings to be made, without imposing on high-grade traits of the stainless steel.
Laser engraving is a versatile method of creating images and text on many different surfaces. With one such surface being on the skin of fruit.
Laser engraving offers a unique way of adding a logo, image or word directly onto the surface of an organic item. It is also a hygienic way of adding a logo to many perishable goods.
It’s not just fruit that can be engraved upon. Vegetables and seeds can also be worked on. Allowing many organic items to be given a logo or image.
It is important to bear in mind that as the laser engraved image is on the skin of the fruit it will wear down slowly over time. It is recommended that this method of engraving is done on items that have a relatively fast turnover of sales. This will decrease the appearance of wear on food items on display.
The main thing that differentiates laser engraving machines is the type of laser they use. It’s crucial to make sure the laser you have in your machine is the right one for the right job.
CO2 lasers are gas lasers based on a carbon dioxide gas mixture which is then electrically stimulated. Effective on non-metallic materials and on most plastics. CO2 Lasers have a great beam quality and are the most widely used type of laser when engraving.
Fiber lasers generate a beam using the ‘seed laser’ and amplify it in specially designed glass fibers which are supplied with energy via pump diodes. Highly suited for metal engraving and for high-contrast plastic markings. Maintenance-free and an average operating lifetime of 25,000 hours make fiber lasers great for industrial use.
Crystal lasers have the same wavelength as fiber lasers so are used for marking metals and plastics. Crystal lasers, however have expensive pump diodes which wear out after around 12,000 hours.
We all run the tap in the morning to brush our teeth and it can be baffling to understand how water can cut heavy duty materials like thick stainless steel. That said, these machines do exist but perhaps they do not quite work in the way you’d expect.
It’s not simple a water pistol that’s controlled by a computer, water could not effortlessly cut metals, no matter how small the jet is, yet water combined with abrasive garnet can. Water shoots down a nozzle, though a ruby or diamond, where it’s introduced to an abrasive garnet.
The formula then heads into a guard where it’s sent down to cut the metal and that’s it. Obviously a great deal of power is required to really give the machine some force, but the cutting method is as simple as that, and the nozzle can be controlled for thick or thin cuts.
The expensiveness of gold and silver can mean that when engravement is made you need really specialist equipment. A typical laser cutting machine can do the job, but if you want to ensure the gold dust and silver gets recycled then you really must have specialist equipment.
Some engraving machines are made for the jewellery process, and this means they’re equipped with a down exhaust and a filter bag, allowing it to recycle the dust during cutting and engraving process. If you want to make sure that not a crumb of gold or silver is wasted then a gold and silver engraving machine is needed.
Every single spot of silver and dist is worth money, and today it’s important to make sure that not a single crumb is wasted, especially considering how rare solid gold and silver is today. If you’re engraving beloved and expensive jewellery make sure you choose laser cutters that have the right device.
