Laser Welding Machine Supplier in Singapore

Welding is a method of joining two or more pieces of metal together using various techniques such as spot welding and arc-welding. Laser beam welding is another of these techniques and uses high powered lasers to join multiple pieces of metal together. The use of a laser beam has many advantages such as narrow and deep welds due to its concentrated heat source. In the automotive industry laser beam welding is quite frequently used for it fast and high volume applications.

Laser beam welding allows high power density which results in localised heat affected zones and this then allows high heating and cooling rates. The size of the laser spot can be between 0.2mm and 13mm, however only the smaller sizes are used for welding applications. The depth of penetration depends on the focal point of the laser and is proportional to the amount of power being supplied. If the focal point is just below the surface of the workpiece then penetration is maximised.

With laser welding a pulsed or continuous laser beam is used, and this will depend upon the application. To produce deep welds a continuous laser is used but on thinner materials such as very thin sheet metals a pulsed laser using pulses only milliseconds long are employed. There are two types of lasers which are commonly in use and these are gas lasers and solid state lasers.

The first type uses mixtures of gases such as nitrogen, helium and carbon dioxide as a medium, whilst solid state lasers use solid medias such as chromium in aluminium oxide, synthetic ruby, neodymium in glass, and the most common type used is crystal which is composed of yttrium aluminium garnet doped with neodymium. When the mediums of either type of laser are excited, they emit photons and form a laser beam.

With a gas laser the lasing medium is produced by using high voltage and low current power sources to excite the mixture, and these lasers can operate in both pulsed and continuous mode. The power requirements for gas lasers are generally much higher than solid state lasers, and can reach 25kW. Solid state lasers have wavelengths much shorter than gas lasers, and operators need to protect their eyes with special goggles or specially designed screens to prevent damage to the retina within the eyes.

To deliver the laser beam to the required weld area, fibre optics are usually employed. Another type of laser is the fibre laser and the gain medium is the optical fibre itself. They are used for robotic industrial welding and are capable of up to 50kW. Laser Welding can have many applications and is very widely used in the automotive industry.

CNC Laser Cutting Machines Supplier

A CNC laser machine is primarily used for cutting metal sheets. It can be used for cutting sheets made of aluminum alloy, stainless steel, titanium and several other metals and metal alloys. This machine is most commonly used for making prototypes made using metals. In other words, a CNC laser machine is mostly used for completing projects that involve use of thicker metals and have limited productions.

A CNC or computer numerically controlled laser machine is the favorite of most manufacturers for a number of reasons. It can be set up quickly, and the engineering time required by it is also pretty low. What's more fascinating is that to set this device up, you will not need to carry out hard tooling of any kind. If you are using this particular technology, you can expect to begin productions of newly received orders the very day those orders are placed.

This is possible only because setting up the device doesn't require much time or effort. In short, if you are running a business that guarantees delivery of metal structures within a specific period of time using a CNC laser machine would surely be beneficial for you. This equipment has made making multiple cuts on a single metal sheet easier than ever before. It comes with ties that will compactly hold all the pieces of the material together.

The machine, on the other hand, will keep on performing the job assigned to it and eventually complete the cutting process impeccably. The person running the equipment will need to shake the sheet for separating the smaller parts from each other. If shaking the sheet is not enough, you can also use a rubber mallet for knocking the parts and allowing them to separate from each other easily.

Due to the shaking involved in the process, often people associated with manufacturing industries refer to the parts created by a CNC laser machine as shaker parts. The machine performs its job using carbon dioxide. CO2 in combination with the machine's high voltage system successfully excites the gaseous substances and results in formation of a light of single wavelength. An inbuilt optic system directs this light towards the metal sheet.

Before the light is projected in the sheet, its diameter is reduced significantly. This makes the beam narrow enough for being used for cutting metals.To keep the parts clean and precise, the vaporized metal gets blown away by a protecting gas. Usually an oxygen or nitrogen mixture is used for this purpose.

In pad printing it uses a flexible silicon rubber pad plate to pick up an image form to another form. Pad printing services are obviously the main method accomplished in printing process.

This method uses an indirect printing process to transfer a 2 dimensional image form a printing plate by using a silicon pad in to a 3 dimensional form. The silicon pad used for this process are capable of picking an image form a flat 2 dimensional plane and transfer the image in to a number of different type surfaces including cylindrical, concave surfaces, convex surfaces, spherical and in to a flat surface too.

Welding is the method of joining two metal bodies or metal parts together with using a beam of light. Ultrasonic welding is a welding technique that it uses high frequency ultrasonic light beams to create a solid state welding of two dissimilar materials. It is most commonly being adopted in welding together plastic materials. The ultrasonic acoustic vibrations are applied to work pieces under high pressure and to make welding the particular product or metal.

When using ultrasonic welding machines to join two dissimilar materials there is no need to use any other type's connective materials such as a connecting bolt, soldering ion or materials, nails or other adhesive materials etc. Automation Systems are computerized and electronically working systems which used in industries to control machines, processes and procedures. The automation systems are more helpful to provide a customizable solution for the complete system integration and an optimal help to all engineering solutions.

Engraving has become a huge business opportunity many people that are interested in the art of engraving can purchase a machine to make a profit.

Some machines are used to etch glass, jewellery, vinyl, and small personal items that can be personalized, and given as gifts. A large business would use a computerized machine to mass produce products that can be distributed and sold. Most commonly used machine is a laser engraving machine. It is so precise, and leaves such clean etching on the item being engraved, it is by far the most popular machine used.

The laser engraving machine is very sophisticated, it is controlled by a computer that controls the speed, intensity, and direction of the laser beam. The precision of the laser is preferred over the use of other machines because it is so accurate and clean. Another reason that the laser engraver is preferred over other engraving machines, there is no need to replace parts.

Replacing of drills and bits is time consuming and costly, where if you own a laser engraver you will not need drills and bits to replace, saving you time and money. The laser can burn some surfaces such as wood, so preparation needs to be taken ensuring that the product does not get damaged. On wood items that have resin, a paper masking tape is used to protect the surface of the wood from turning black or burning.

This process is necessary to preserve the product being engraved, and will make clean up much easier on the person engraving the wood. Plastic products that will be engraved will also need to be handled with care. Burning plastic can cause fumes and vapors in the air, wearing a protective mask will prevent the harmful fumes from being breathed into the lungs. Other equipment such as fans are required when engraving plastic items.

A manufacturing company has to produce a product in thousands of units. These products could be parts, components or a complete device. Let's say, if an auto part is to be produced for a particular car, how all units would be in exactly same size, neither a millimetre more nor less. In the wake of this obsession, CNC Cutting machines were born. These machines can manufacture thousands of units subsequent to than tall precision, precise in size, weight and from each and every one aspect. 

Industries that have to make clones of a product in massive number have to set up CNC machines in their industrial unit. Precision is the prime requirement which was made possible with CNC Technology in cutting machines. These machines can cut your operational cost by handling several tasks for that you need a number of personnel. Advanced technology used in CNC machines simply add Efficiency and Effectiveness to your production process and therefore bringing up additional profitability afterwards.

Usually, size of cutting tables in a CNC machine is 4x8' which is good capable to carry large sheets of any material like wood, metal, plastic and glass. If the table size is shorter, machine operator would often have to change his position to adjust the angle of sheet. So, whenever you are going to consider a CNC machine, remember to check the table size. If you are certain that you would have smaller sheets to lay on cutting table, you can be flexible on table size. 

Amongst all types of CNC, laser and plasma machines are most common to be used in manufactures. Laser and plasma cutters are ideal for cutting metal like steel, aluminum, metal alloys etc. Laser cutters are preferred when the sheets are not very thick. It can cut 3D shapes with perfect precision whereas plasma cutters are great for cutting thicker sheets. Plasma cutters are usually put into work for cutting 2D shapes where too much precision is not the goal. These state-of-the-art CNC machines require very short setup time.

You can start production on the day you receive an order. Unlike other cutting machinery, it would not take you days and weeks to start. You can get maximum outcome once you add a CNC machine in your production lines. Humans do tire and so do machines. Everyone and everything needs rest after certain hours of working but surprisingly, you can keep CNC cutters running as much as you have to. 

You can run them uninterrupted 24 hours a day, 7 days a week, 365 days a year unless you meet your production target. Its advanced technology lets you work with it non-stop, however, it will need to be turned off if there is a maintenance work to be performed. Another edge of CNC over other milling machines is that you do not need very highly skilled staff to work on it. 

These machines require very simple orientation which lets you hire unskilled operators on cheap cost and then train them accordingly. On the contrary, other machines need very skilled and professional engineers to operate. Many industries are turning their production through CNC technology observing all its innovative features.

CNC Engraving Machines

CNC engraving machines work great for when you want to engrave into metals with cuts more than a few thousandths deep. This is opposed to the process of burnishing or dragging on metals. Using CNC engraving machines to engrave into metal presents end users with a variety of options to consider prior to production. When using CNC engraving machines to engrave into metal, first think about how you are going to hold the material.

Engraving into metal will most often exceed the strength capacity of tape or holding mats. Ideally, you want the holding device to completely keep the material from moving as well as be easy to use. You need to be able to set and move the material as efficiently as you can without sacrificing your hold or damaging the material. If you're using CNC engraving machines for highly competitive work, you really should design a custom jig that's specific to that job.

A good jig will allow you to quickly, easily and accurately place the material for multiple engravings of the same job. It's worth spending some extra time and money creating a jig that makes it easy to hold and remove the material. Engraving into metal quickly eats up cutters. You really should use standard engraving cutters that are designed for engraving metals. Double ended, double fluted end mills work best.

You'll find end mills deliver a much superior quality and are easy to use. No matter which style of cutter you use, keep many duplicates on hand for replacement of broken cutters and re-sharpening. If this is a big part of your business, do yourself a favor and purchase your own cutter sharpener. Definitely use a cutting fluid. Using a cutting fluid to lubricate the cutting surface will help to cool and protect your cutters.

This also helps produce a smoother finish to the cut. Mystic Metal is a great cutting fluid that's available through most suppliers. Arming your CNC engraving machines with a collect spindle is essential for this type of engraving. You'll notice that standard top load spindles don't have the support necessary at the bottom of the spindle, causing the cutter to chatter under large engraving loads. This severely limits your engraving quality as well as damages the machine.

It is a good idea to use a slower Z-axis speed when engraving stainless materials. This gives the cutter time to fully penetrate the material to the desired depth before moving laterally. You can always adjust the speed of the Z-axis during production for the CNC engraving machine as needed. Rotary engraving on stainless steel is a challenging application with CNC engraving machines.

Yet stainless steel is a frequently requested material due to its low maintenance, heat resistance and inert properties. It's critical that those using CNC engraving machines understand that planning the production of the job is very important. Using the proper tools and fastening devices can make a project run efficiently and effectively.

The Latest Techniques of Fiber Laser Marking Machine

Most laser marking techniques impinge upon either engraving the mark into metal or plastic components, or ablating a surface accrual to character a contrasting material underneath. Both processes usually require high vibrancy pulsed laser systems and of course shape process debris.

Fiber lasers are now a robust industrial tool subsequent to a unique series of capabilities that enable a broad range of exactness materials giving out manufacturing methods. Fiber lasers pay for low supervision costs, a rushed ROI, a little footprint and exceptional reliability, and are hence enjoy a growing submission within the laser-assisted manufacturing industry as a cost-energetic exchange to enough laser design.

Laser marking is well-ventilated to generate high contrast, easily readable and durable identification roughly a broad variety of components for industrial use or consumer products. Computer generated vector or bitmap patterns (logos, barcodes or text) can be engraved or etched using a non-associations process onto metallic and non-metallic materials, including metals, plastics, glass, electronics, PCBs, wafers, medical devices, sporting goods and packaging.

An inclusion of a reliable industrial laser, hasty and accurate galvanometric imaging systems and convenient computer rule provides manufacturers previously a unique assimilation of speed, permanence and versatility that cannot be matched by any additional marking technique.

Many stand-in laser designs have found their way into materials admin applications. Fiber lasers are however revolutionizing many of these applications through a whole of bigger optical engagement, augmented system malleability, high component comply, long taking place-times and exceptional reliability.

Critical to many marking applications, they do something not exhibit the shortcomings in spot size operate found in late gathering laser designs - at all knack levels, across each and every one pulse sequences and during each and every one lifetime of the laser, the spot size remains little, predictable and consistent.

The little spot size and high beam character with want high irradiance at the focus, in view of those manufacturing tools equipped later than fiber lasers can fabricate augmented results faster and at demean gift levels. The focused beam consistently treats abandoned a intensely little place of material, following the gain that deeply tiny heat is generated in the surrounding area. High environment correctness marking, welding and acid can be performed near (0.1 mm) to the most complicated and intricate component parts.

Factoring in the honourable operation and power modulation adaptableness, fiber laser technology is now frequently fixed as an remodel on intensity of usual flash-lamp pumped hermetic avow, or even DPSS laser technology in many relationship laser-assisted industrial manufacture segments. The consistent and greater than before marking take steps means edited portion costs, longer taking place-times and augmented production character behind less scrap. Fiber lasers are in addition to exceptionally physically robust and for that reason okay for the most challenging of industrial environments.

All of these factors equate to a plug-&-play, child part-forgive architecture for systems integrators looking to scratch press to the fore, production and servicing costs, once the additional gain of mammal practiced to give the decrease fanatic bearing in mind a greater than before, more nimble product. Last but not least, the grow less enthusiast will be adept to focus around their business demands rather than having to become laser maintenance experts.
