CNC Machining Parts are Becoming Popular

With the continuous development of science and technology, traditional processing and development techniques can no longer keep up with the current development rhythm. In order to improve production efficiency and quality, CNC machining technology is widely used in production, and CNC machining parts have gradually become the mainstream.

CNC machining has the following advantages:

1. The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the parts, you only need to modify the part processing program, which is suitable for new product development and modification.

2. The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.

3. The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.

These advantages of CNC machining make CNC Machining Parts have better quality, higher precision, richer styles, and more attractive shapes. The most important thing is that this high-efficiency production mode makes the price of CNC Machining Parts much lower, saving the cost of the company. Dongguan zhongda model technology co., ltd. adopts CNC, 3D printing, vacuum casting, sheet metal and other processes, specializing in the production of various metal and plastic rapid prototyping products. I believe you can get the goods you want here.

What is the principle of digital night vision device?

Digital night vision device is a very popular detection machine in recent years. Many people are curious about the principle of digital night vision device. Today I will explain the principle of digital night vision device.

Compared with traditional night vision devices, the principle of digital night vision device is completely different. A digital night vision device generally does not use an image extension tube as an image intensifier, but uses a low-illuminance CCD as an image intensifier. The low-illuminance CCD can recognize very dark light, and then convert it into a visible digital signal, which can be displayed on the LCD screen inside the night vision device.

Therefore, the digital night vision device has a built-in LCD screen, while the digital camera is just an external LCD screen. Digital cameras use ordinary CCDs, while digital night vision devices use low-illuminance CCDs.

It is for this reason that the low-light CCD of the digital night vision device is a very critical part of the digital night vision device, just like the image tube of the traditional night vision device.

How to clean the cooling system of vertical rubber injection molding machine

The flow rate of the hydraulic cooling channel of the vertical rubber injection molding machine is generally 40L/min, and the barrel is about 20L/min. Because there are too many POM materials, the mold does not require cold water, so how to meet the cooling requirements of the injection molding machine? and Control the cost?

If the 40T machine is only for cooling hydraulic oil, you need to buy a plastic bucket and use an air-conditioning pump to pump water to cool it. The air-conditioning pump must be bought. Generally speaking, the electricity consumption is equivalent to a 100W light bulb, which is very energy-saving.

Compared with other injection molding machines that need to be cooled, the engine may be overheated for a long time and there may be a danger of cylinder explosion. If you want to avoid such bad failures, the radiator must work normally, but the key is to keep the cooling system running normally. Today's engines operate at a higher temperature than in the past, but because of the addition of the emission control system, the radiator, engine compartment and grille area have also become smaller.

It is generally recommended that the vertical rubber injection molding machine clean the cooling system once a year to maximize the life of the radiator. First of all, make sure that the engine is in a cooling state and turn off the engine; remove the radiator cover to ensure that the engine is cool; open the drain plug (or water pipe) at the bottom of the radiator to let the coolant flow into the barrel; close the drain plug (or install the water pipe) You can fill the radiator with water; turn on the engine, turn on the heater control system (so that you can operate the heater control valve), so that you can add the cooling system cleaner, empty the engine for 30 minutes; turn off the engine to cool down for 5 minutes, generally you can Drain the liquid in the radiator; close the drain plug, fill the radiator with water and let the engine run for 5 minutes; then refill the compound of 50/50 water and glycol antifreeze/coolant.

HOW TO CHOOSE GOOD DISPOSABLE GLOVES？

　　 1. Generally speaking, you need to look at the material first: Disposable gloves are basically made of new polyethylene materials. The new materials are non-toxic and tasteless, with good transparency, safety and hygiene, so they can directly contact food. Don't choose to produce the recycled material particles, the appearance is black, even dark, taste, and the hygiene is not up to standard.
　　
　　 2. Look at the appearance: the qualified sealing is good, and the water is not leaking, so that in the face of greasy, water stains, the dye is not easy to break, and the toughness is strong, the pull is strong, and wearing it can protect our hands from oil.
　　
3. Look at the thickness: The thickness of Disposable gloves is directly related to the weight of a single gram. Generally speaking, the weight of a single gram is thick, and the thickness of a small gram is thin. The thin is cheap, but the utilization rate is low because it is too Thinner is easier to break, and the better the thickness, the higher the price. Such gloves have strong barrier properties, are not easily broken, and are more resistant to oil, water, and dirt.
　　
　　 4. Look at the size: choose your own size model, pay attention to the appropriateness of the actual size, in order to be more accurate, it is best to measure before buying, generally the length from the middle finger to the wrist, and the width of the palm. It is much easier to choose the size of the glove according to the measured size, and it is convenient to choose the appropriate size. It can't be too long, too short, or too big. The common sizes are large, medium, and small. Choose according to your needs.
　　
       5. Look at the packaging: Generally speaking, the selection of the packaging has the production license certification, hygienic test report, and can provide the test certificate; the outer packaging has the production date, shelf life, production batch number, manufacturer address, weight, length, width, thickness of the packaging glove Products with the most basic information.
　　
　　 6. Look at the manufacturer: Disposable gloves are produced in regular factories, generally with complete qualifications, workshop standards, and process production conform to industry standards. Do not choose small workshops and black factories. There is no guarantee for health after-sales.
