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.

1. Necessary laser cutting machine protective equipment, wear protective glasses to prevent laser damage to human eyes. laser cutting machine ，Others in the work area should not look directly at the laser while cutting.
2. There must be a matching dust removal device, try to operate in an environment with unobstructed air, and wear masks as much as possible.
3. When arranging the cutting site, paint the site and walls of the working environment with dark colors to reduce radiation.
4. Do not touch the incision site immediately to avoid residual heat burns.

At the moment, the big-range sculpture supplies out there generally involve rock, cement, steel, sandstone, sculpture design，window dietary fiber reinforced plastic-type, and so forth. So, what resources are available to the sculptures we have seen in the open air?
Stone sculpture is divided into granite sculpture and marble sculpture. Granite includes a challenging consistency which is not easily eroded or weathered by acidity and alkali, whilst the texture of marble sculpture is delicate, wonderful, solemn and stylish. For that reason, generally speaking, granite sculptures are suggested for outdoor usage, and marble sculptures are suggested for interior use.
The concrete sculpture utilizes galvanized stainlesss steel as the keel and cement because the principal fabric. Cement sculpture is additionally the most typical sculpture material at present. Due to its strong plasticity and wind resistance, it offers solid resistance to the climate, h2o and standard levels of acids, alkalis, salts, and other fats and chemicals. As well as the longer some time, the stronger the strain level of resistance.
