PMMA模塑焦点

（1）熔融速度可降低约40%至50%以增加熔融热的产生，熔融橡胶压力在70至90kg/cm2之间更合适，以便调整材料温度水平。　　

（2）当出现收缩或真空气泡，其他条件无法解决时，可以添加背压，在5kg/cm2~20kg/cm2之间，以解决背压过高的问题，但会使土堆形状过热和行驶困难。　　

（3）如果在加热物料管中停留时间过长，容易产生过多的气体，有时由于气体的阻力，螺杆不容易驱动，可以通过连续注射和放松来消除气体。　　

（4）如果肉厚的成品通过冷却缩短而不变形，可以用温水浸泡并缓慢冷却，但表皮和中心之间的温差不会太大，以防止收缩真空气泡的发生。　　

（5）当成品有残余应力时，在与溶剂接触时，成品的强度会降低，以消除热模产生的内应力，材料温度升高，注射压力降低，如压缩成型，内应力几乎不存在。　

（6）如果成品已经大量生产，为了不因内应力过高而报废，可以进行抗火处理，这可以缓解外表面的张力，缓解内应力。　　

（7）丙烯酸亚基回收是清洁物料管道的最佳材料，设定温度为240°C左右。　　（8） 如果在低温下成型，材料管后部的温度较高，螺钉不会产生尖锐的声音

PMMA molding focus

(1)The melting speed can be slowed down by about 40% to 50% to increase the generation of melting heat, and the melting rubber pressure is more appropriate between 70 and 90kg/cm2, so that the level of the material temperature can be adjusted. 　　

(2)When there is shrinkage or vacuum bubbles, other conditions can not be solved, you can add back pressure, between 5kg/cm2 ~ 20kg/cm2 to solve the ‘back pressure if too high, but will make the shape of the mound overheating and driving difficulties. 　　

(3)If it stays in the heated material pipe for too long, it is easy to produce too much gas, and sometimes the screw is not easy to drive due to the resistance of the gas, and the gas can be eliminated by continuous injection and relaxation. 　　

(4)If the meat thick finished product is not deformed if it is shortened by cooling, it can be soaked in warm water and cooled slowly, but the temperature difference between the epidermis and the center will not be too large, so as to prevent the occurrence of shrinkage vacuum bubbles. 　　

(5)When the finished product has residual stress, in contact with the solvent, the strength of the finished product will be reduced In order to eliminate the internal stress can be produced by the thermal mold, the material temperature is increased, the injection pressure can be reduced, such as the compression molding, the internal stress is almost non-existent. 　

(6)If the finished product has been produced a lot, in order not to scrap due to the internal stress is too high, it can be implemented to defy the fire treatment, which can alleviate the tension of the outer surface and ease the internal stress. 　　

(7)Acrylic substate recovery, the best material for cleaning the material pipe, set about 240 °C. 　　(8) If it is formed at low temperature, the temperature of the back section of the material pipe is higher, and the screw will not produce a sharp sound.
