With the rapid development of science and technology, the use of plastics in modern medicine is steadily increasing. Medical devices made from injection-molded plastics help reduce health care costs, infectious diseases and pain management. High-tech polymers are used in medical device prototyping and are often used to create improved prosthetics and devices to reduce the risk of infection. Medical plastic injection molding directly improves patient safety and the ability to save more lives. High-gloss injection molding: the basic process of high-gloss injection molding is to rapidly heat the surface of the mold with high temperature and high pressure steam before injection molding, so that the surface temperature of the molding mold cavity reaches above the glass transfer temperature (TG) of the resin plastic, and then inject the plasticized plastic melt into the closed mold cavity. During the injection phase, the mold temperature is kept constant by high temperature and high pressure steam. After injection molding, stop the air supply, blow out the steam in the tube with the air pressure of the duct, and then inject cooling water to make the mold temperature drop rapidly, until the mold is cooled and opened to take out the product.

To prevent the battery from suddenly losing its electricity, the best way is to pay more attention to the "help signal" issued by your car. This signal has the following manifestations: First, the starter does not turn or rotate so weak that the starter cannot be started; second, the headlights are darker than usual; and third, the speaker volume is small or not sounded. When the above problem occurs, the owner must check whether it is a battery problem.
In order to minimize the battery's power consumption, the expert put forward two suggestions: First, to avoid turning on the lights or listening to the radio for a long time in the event of engine stall; Second, even if the engine is running, if the parking time is long, it should be unnecessary. The power of the used electrical equipment is turned off. To develop good car habits can avoid unnecessary difficulties.
But if there is a sudden battery outage, there are several ways to "self-help":
First, the start of the cart is the most familiar and most effective emergency starting method, but this is a last resort and cannot be used often because it has some damage to the engine and the clutch. The automatic vehicle should especially avoid using this. Method start.
Second, in order to prevent the battery from being discharged when the battery is dead, the owner should prepare a jumper cable in the vehicle, which can be purchased in general auto parts stores. However, when connecting jumper cables, you must not mistake the connection sequence of jumper cables. The positive terminal of the dead battery is connected to the positive terminal of the rescue vehicle battery, and the negative terminal of the rescue vehicle battery is connected to the metal part of the interior of the engine compartment. After the jumper cable is connected, the engine of the rescue vehicle can be started, and the engine speed can be slightly increased. After about 5 minutes, the uncharged battery can be charged. After charging is complete, remove the jumper cable in the reverse order of connecting the jumper cables.
The most reliable way is to contact the rescue vehicle in time, then connect the jumper cable and temporarily charge the rescue vehicle to start the engine.
Finally, experts advise that the battery life is generally 2 to 3 years. After this period, the car pays special attention to the maintenance of the battery, and if necessary, it is replaced in time to avoid danger.
