Several important factors that need attention in injection molding

Generally speaking, the major factors of injection molding are pressure, back pressure, temperature, time, holding pressure and time.Injec

tion molding is also commonly called injection molding, it is an injection and molding method

The advantage of the injection molding method is that the production speed is fast and the efficiency is high. It can be automated when performing related operations. Due to the variety of colors, the shape can be simple to complex, and the size is generally from large to small. Accurate and easy to replace products, it can be made into complex shaped parts. Injection molding is suitable for mass production and complex shape products.

Injection molding is a very commonly used manufacturing process for manufacturing plastic parts. Injection molding can be used to manufacture various products, which vary greatly in size, complexity, and application. The injection molding process generally requires the use of injection molding machines, original plastic materials and molds. The plastic is melted in an injection molding machine and then injected into the mold, where it cools and solidifies into the final part.

What are the specific characteristics of air freight service from china?

In recent years, air freight service from china transportation efficiency is one of the development directions of the express delivery industry. Although the start time is late, but the development speed is faster than other transportation methods, what are the characteristics of international air transportation?

1. The first is to have a higher delivery speed

Now the market competition is very fierce, the time is changing, and the market's wind direction may change, so the cost of time is a very important factor that companies need to consider. The higher delivery speed of air freight service from china has now become the current commodity competition in the international market. Favorable factors.

2. Air transportation is very suitable for fresh and seasonal products

Fresh commodities have high requirements on time. The delay in transportation may cause the commodities to lose their original value. Therefore, air transportation can ensure the fresh survival of commodities, which is conducive to opening up long-distance markets. For seasonal commodities, air transportation can ensure that the market is available before the sales season, to avoid the cost of commodities that cannot be sold due to missed seasons.

3. Low breakage rate and good safety

Generally, the goods that can be transported by air are relatively high in value, and the ground operation process of air transport is generally strict. Therefore, the management of the Russian system needs to be improved, which can reduce the damage rate of the cargo and improve safety.

4. Save packaging costs and speed up capital turnover

Fast air transportation, short transit time, and fast delivery speed, which can reduce the inventory of goods, reduce storage fees, insurance fees, and interest expenses. In addition, the air transportation custody system is perfect, the cargo damage and the cargo difference are small, and the packaging can be simplified accordingly. This can reduce packaging costs and insurance costs, and the speed of product circulation is accelerated, which also speeds up the capital turnover rate.

Where Is The Medical Stretcher Suitable For Transferring Patients?

What are the requirements of the medical stretcher generally used in stairs? The general stair stretcher is mainly used to transfer patients up and down stairs in high-rise buildings.

Generally, this kind of medical stretcher adopts a foldable structure. Because it is small after folding, the general stretcher will be equipped with four wheels. The back of the stretcher will also have two foldable handles. The lower end of the front of the stretcher can usually be Two telescopic lifting rods.

How to clean car HONDA GCV160 carburetor

          First, you need to remove the air filter, then start the engine to allow the engine to reach the maximum speed, and then quickly press the carburetor air inlet with the palm of your hand.

          At this time, strong suction power can be felt at the palm of the hand, and the engine speed also gradually decreases. When the engine speed is low, quickly remove the palm to restore the engine to its normal state.

          Repeat the above two parts several times until the engine is working properly. If the carburettor cleaning agent is available on the car, it can be used together with a better effect, so the number of times can also be reduced.

          Using this method, there is no need to worry about damaging the HONDA GCV160 carburetor. From the practical effect, after the above cleaning, failures such as weak driving and acceleration lag caused by the carburetor's poor fuel supply can be eliminated. The principle is to suddenly block the air inlet when the engine is running at high speed, and use the working inertia of the engine to generate a greater vacuum in the carburetor, thereby increasing suction to clear the oil passage and the air inlet.

Under what circumstances will RFID electronic tag fail?

RFID electronic tag is now very common in our lives. RFID is similar to bar code scanning, but RFID uses a special RFID reader and a special RFID electronic tag that can be attached to the target. The frequency signal is used to transfer information from the RFID electronic tag To RFID reader. If the RFID electronic label fails, it will not be able to scan and apply, so under what circumstances does the RFID electronic security label fail?

Generally speaking, these three situations will cause RFID tag failure. The first case is the tag damage: because the RFID electronic tag has a chip, if the chip is pressed by external force or destroyed by high static electricity, it may cause failure. . If the RFID signal is damaged by the antenna, it will also cause failure. Therefore, RFID electronic tags must not be damaged or torn by compression, so most demanding RFID electronic tags will be packed in plastic cards to avoid damage by external forces.
