Laser Engraving On Perishable Goods

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 Dangers Of Using The Newest Technologies

Many of the most successful businesses owe their success to their ability to adapt to new and upcoming technologies.

However their are dangers to immediately incorporating new technologies, especially into established business models.

Quickly changing the way something operates may cause different issues to crop up further down the production line. What is seemingly advantageous initially may spawn other problems, that are yet to develop into something of concern.

Problems can also arise when human beings need to change with the new technologies. Humans need time to adapt to new things and will need to be trained in using the new technology.

These are common roadblocks and considered merely stepping stones to the businesses that can see the potential in changing an established way of doing things. In braving the dangers the business may learn something it didn’t expect and the rewards can far outweigh simply an increased income.


The Advancement Of Solid State Drive Technology

Solid State Drives (SSD’s) are seeing their use increase considerably across IT systems around the world. Their near instantaneous ability to access data, silent running and size efficiency all add up and the result is that of a technology soon to surpass the traditional hard drive.

As mentioned, SSD’s are the new technology looking to take the place of a hard drive. SSD’s are available for purchase now, but the major thing that’s stopping their sale is the price. Consumer-grade SSDs are still roughly six to seven times more expensive per unit of storage than consumer-grade hard drives.

Apart from this and the fact that this price will drop over time as the technology is produced more. SSD’s seem like they will take over the hard drive, becoming the main way we all store our data.

Many laptops already make use of SSD storage as standard. Intels range of ultrabook subnotebooks use SSD technology as part of the framework for a super sleek, yet highly functional portable computer.

The Origins Of The Plasma Cutter

A plasma cutter is a versatile piece of equipment. Able to cut through varying thicknesses of steel and leave a relatively clean cut.

Plasma cutting began its origins as plasma welding. This was a widely used way of cutting in the 1960s. Alterations were made to the welding system to turn it into a cutting tool, of which made it a productive way to cut sheet metal and plate in the 1980s.

It had the advantages over traditional “metal against metal” cutting of producing no metal chips, giving accurate cuts, and producing a cleaner edge than oxy-fuel cutting. Early plasma cutters were large, somewhat slow and expensive and, therefore, tended to be dedicated to repeating cutting patterns in a “mass production” mode.

A plasma cutter works by blowing a gas at high speed out of a nozzle. At the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is hot enough to melt the metal being cut and moves fast enough to blow molten metal away from the cut.

Laser Engraving Laser Types

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

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

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

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.
