1. The temperature of the molten plastic is too high, which will increase the cooling time of the product.Injection Industry， At this time, the temperature of the barrel should be reduced, the screw speed or back pressure should be reduced, and the temperature of each section of the barrel should be adjusted.
2. The temperature of the injection mold is high, which affects the cooling and shaping of the molten plastic, which will cause the injection molding product to be closed and closed and shut down. To improve this situation, targeted cooling of the water channels is required.
3. Insufficient heating of the injection molding machine barrel. In this case, a machine with a large plasticizing capacity should be used or the preheating of the material should be strengthened.
4. The injection molding machine nozzle drools. In this case, the temperature of the barrel and nozzle should be controlled or the self-locking nozzle should be replaced.

Each laser marking equipment is equipped with an industry discipline mirror which can also be called horizontal industry attention mirror and scanning mirror. fiber laser marking machine ，Field mirrors are primarily used to focus the sunlight released by the galvanometer on the aircraft.
The main features of the galvanometer are:
1. Increase the detector side light accident capability
2. Homogenize the uneven brightness of the photosensitive surface of the sensor
3. Under the same primary vision method, if the same detector position is used, the additional subject lens will minimize the area of the sensor, which can expand the viewing area as the event flux increases

There are many reasons for burrs in injection molding. It is necessary to comprehensively consider various factors such as injection molds, mould supplier ，injection molding processes, and raw materials.
mold
Injection mold precision is poor. The flatness of the core can create gaps when the mold is closed, resulting in burrs on the parting surface.
Injection molding process
Too much material added during injection molding can cause burrs. If the temperature of the injection barrel, nozzle or mold is too high, the viscosity of the plastic will decrease, the fluidity of the plastic will increase, and it will also cause burrs on the parting surface.
raw materials
Too high or too low viscosity of the plastic material can cause burrs on the parting surface. The uneven size of plastic particles will change the feeding amount of the barrel, and burrs will appear on the parting surface.

You can find 4 primary versions of healthy connectors. There are lots of far more, but we simply pinpoint the principal ones.rc connector， The particular managing connector depends upon the battery maker.
Whilst the basic principles of most well balanced connectors are similar, some companies use slightly distinct wires sequences for well-balanced connections. You will find off-the-rack adapters that change one healthy connector to another.
But it's essential to successfully understand what connector your battery pack, charger, balancer or body fat alarm system utilizes.
Potential Connections A number of power connectors are offered. Determining what one is right for you is a combination of app, model sizing, and restrictions that actual physical wrapping and routing may supply.
A tiny energy connector commonly available on small versions, games, and tiny excess fat totes. JST connectors carry lower recent and are most frequently present in auto gadgets like servos, gyroscopes, receivers, and recipient switches.

There are many kinds of outdoor sports, such as extreme cycling, outdoor mountaineering, sports, skiing, golf, camping, etc. For this reason, for various sports activities, Sports Sunglasses，the efficiency requirements for sports glasses are also different, so various sports can also make sunglasses.
Different track and field sports should be designed with professional sports activity glasses. For example, track and field safety sunglasses must be risk-free, defensive, comfortable and attractive to those engaged in vigorous sports
For sports enthusiasts in areas with severe sandstorms, goggles suitable for long-term outdoor sports required by myopia track and field enthusiasts, the birth of the Myopia Sports Activity Cup has brought them good news
In addition, when exercising in the sun for a long time, be sure to buy polarized sports activity glasses for mountaineering enthusiasts. The snow around the peaks is highly reflective and easily hurts the eyes. You can wear snow goggles.
