Requirements for a laser cut vector drawing?

If a drawing contains multiple layers, it may be unclear what should and should not be cut. Avoid confusion and merge all. Remove support lines and comment that should not be cut/engraved out of the drawing. Remove all, even invisible, layers, shapes and pictures used as a basis and no longer needed.Get more news about laser cutting line,you can vist our website!

► Remove double lines in the drawing. If there are two lines (on top of each other) in the drawing, the laser will cut them both. So make sure lines do not overlap. For example if you put two squares together, clear one side of one of the squares.

► The color of the lines and planes must be RGB and the opacity (alpha value) must be set to 100%. If it is transparent, even a tiny bit, the laser skips the lines, or engraves the planes with less power.

► Due to the burning away of the material cutting loss (cut width or kerf) occurs. This is different for each material. For wood and acrylic from 3mm to 5mm we hold a cut width of about 0.155mm. The laser will always cut across the center of the line.

► Please note: the cutting loss is dependent on the material and the thickness of the material. For something 'snap-fit' to fit, we recommend that you first make a test on the material in question.

► Make sure that pictures and images are really 'embedded' in the file, and are not linked externally. Then you save your vector drawing, but we do not get the pictures!

► Put text fonts in the drawing to a vector line (path), otherwise the texts will open on our computers in a simple Helvetica font. This will ensure that the text won't be cut in the wrong font!

► If you want to cut out a letter, note that you use a font that is suitable. Most fonts with characters having an enclosed part, will fall as one part out of your material. Such as eg in e, p, or a. Fonts who do get cut properly are called Stencil fonts (also called Army fonts).

► Beware of tiny shapes. Which can go up by the cutting loss or objects with a size of less than 5mm, will fall through the frame of the machine. Therefore, we can not guarantee that we will actually send them!

Pins & Bushings – Pins and bushings form the hinges that allow the links of the track chain to move around the sprockets & idlers. As pins and bushings naturally wear it primarily occurs on a single side of the pin and the matching surface of the bushing, which allows the track pitch to extend, causing a stretched chain that runs loose. Maintaining proper pins and bushings will keep your undercarriage tracks running effectively.


Oil vs. Oil-free Rotary Vane Vacuum Pumps

When selecting a rotary vane vacuum pump, one of the decisions you will have to make is whether to get an oil-sealed vacuum pump or an oil-free pump (also called dry pumps).Get more news about custom dongnan micro switch,you can vist our website!

The best choice for you is really going to depend on the applications that you require the pump for.
Some of the drawbacks of using an oil-sealed pump are that you will need to regularly change the oil to ensure that the unit lasts as long as it should. The use of oil also increases the risk of contamination if there is no check valve installed on the inlet of the pump. Additionally, the cost of disposing of contaminated waste can be quite high.

Oil-free vacuum pumps
dry vacuum pumpOil-free pumps will cost you more upfront than traditional oil-sealed pumps, but they require hardly any maintenance and don’t need the regular oil changes that their oil-sealed counterparts do. There is also no risk of producing contaminated waste.

There are, however, some drawbacks to using oil-free pumps. They run hotter and are not built to handle large amounts of liquid and particulates. Additionally, they can be quite a bit louder than oil-sealed pumps. Vacuum levels are in the 25” HgV range for traditional vane units.

Which option is better?
In choosing between an oil-sealed rotary vacuum pump and an oil-free pump, the best choice depends on your operation and what you need your pump to do. Some of your considerations should include energy consumption, pumping speed, vacuum depth, and factors such as your budget and sustainability.

Is It Necessary to Equip Extension Sockets with Overload Protectors?

As a necessity for everyday electricity use, extension sockets involve safety in use. Many countries have strict requirements for the structure and materials used in the local production or import of extension sockets. For example, the socket must be equipped with a childproof safety door. The cross-sectional area of the copper wire must be specified according to the length of the power cable. And the shell must be made of flame-retardant material in order to avoid fire. There is a component called an overload protector in the extension socket, which is also intended to ensure safety in use. There is no mandatory requirement for this part of the market to be configured, but if it is, the cost will rise. If you want to start importing extension sockets for sale in your market, then you should think about whether it needs to be equipped with an overload protector.Get more news about Overload Protection Socket,you can vist our website!

To determine if an extension socket needs to come with an overload protector, you first need to know how overload protection works and to a protective role in an extension socket.

Extension socket is a single socket power expansion equipment, a single power output port to expand into a multi-terminated power output hole, to meet the simultaneous use of a variety of household appliances power supply. However, there is a limit to the amount of electrical power that can be loaded. For example, the total power of an electrical appliance marked as 13A, 250V~ cannot exceed 3250W (12A◊250V). Once the load capacity has been exceeded, it is easy to cause the charging equipment to fail or the wire temperature to rise and fire to occur. It is not always possible to calculate the total power of an electrical appliance, so overloading an extension socket is inevitable. To ensure safety, some of these sockets are equipped with overload protectors. When the load on the extension socket exceeds its rated maximum power, it will automatically cut off the power supply to protect electrical property and personal safety.
If this alone does not give you a sense of the effect of the overload protector on the extension socket, you can refer to the following experiment.

First, we use an extension socket that is 13A, 250V~, maximum load capacity of 3250W, without overload protector, as sample No. 1. In the beginning, we connect a 1500 watts electric iron into sample NO.1, the sample reacts nothing. Then connect a 1000 watts of electric rice cooker, extension socket and appliances are normal use. But when connected to a 1200 watts electric heaters and three electrical appliances work a few minutes later, we use a thermometer to measure the extension socket shell surface temperature. It turns out that the temperature is higher and higher. If you continue to plug in other high-power appliances, the temperature will rise rapidly.
Secondly, under the experimental situation, when flammable objects such as paper towels, sponges and cotton cloths are used to cover the extension socket, the temperature rise accelerates and can even reach the ignition point in a short time, giving rise to ignition hazards.

Finally, we use the same rated power of 3250W but with overload protection extension socket, the same in turn access to several appliances, 3 appliances at the same time power working about 5 seconds, the extension socket automatically powers off. Turn off the power switch, remove one of the appliances, wait for 5 minutes or so for the temperature of the extension socket to return to normal, reset the overload protector button, then turn on the power switch, the extension socket continues to supply power normally.

The above experiments show that a qualified overload protector can cut off the power supply in case of overload and prevent the extension socket or the appliance from heating up and causing a fire hazard. When the loading power is normal, the power supply can be restored normally.


DATSUN-NISSAN

There was a time when the only cars you would see on American streets were made in America. There may have been a few exceptions, but they were from top European brands.

Laser Cutting For Textiles And Clothing

Since the 19th century, laser cutters have been used by the garment industry to improve productivity, speed and accuracy. From achieving clean-cut edges to preserving the quality of fabrics, there’s no shortage of benefits when it comes to laser cutting textiles.Get more news about Clothing Co2 Laser Cutting Machine Manufacturer ,you can vist our website!

In the past, laser technology came at a high price and was thus reserved for big brands that could afford the equipment. Over time, laser machines have become more portable, accessible and affordable — now any small business can reap the unique benefits offered by laser processing. Here’s a closer look at the function of laser cutting machines and how they’ve revolutionized the clothing industry.
If you’ve never used a laser cutting machine before, you may be wondering how it works. A classic laser cutter is a computer numerical controlled (CNC) machine that operates electronically. It features a laser head with an autofocus lens that moves over your material (such as the fabric surface) and pinpoints the exact location to begin the cut. Most laser cutters use one of two lasers:
In addition to cutting, laser cutters are often used to engrave materials. During the laser engraving process, a laser beam is set at high heat to vaporize material — this physically removes some of the substance, ultimately creating a visibly noticeable impression. The minimum depth required for laser engraving is 0.005 inches, although the process may be repeated to achieve deeper marks. Laser engraving is often used to make serial numbers, logos and customized designs.

Cutting and engraving using a laser cutting machine allows for higher accuracy, increased speed and elevated productivity. Not only are laser machines incredibly precise, but they can also get the job done in a matter of seconds. These elements make laser systems a valuable tool in textile processing.
Improved Accuracy
Every year, over 13 million tons of textile waste is produced on a global basis. While some of this waste is a result of consumers getting rid of old clothes, a solid portion comes from fashion companies throwing out unusable clothing. One of the best ways to prevent waste and ensure all materials are being used is by laser cutting clothing.

Because laser cutters use electronic CNC machines, they’re able to determine the exact location of a cut and execute it smoothly. The standard laser system has a high precision level of about ± 0.0005 inch. Sheet metal and manual cutting methods, on the other hand, lack this technology and are thus more prone to mistakes. By consistently making accurate cuts, you can reduce manufacturing mistakes and create uniform, high-quality products that boost your brand reputation.
