lcp料筒温度通常料筒温度、喷嘴温度、材料熔融温度如表所示。如考虑到螺杆的使用寿命，可以缩小后部、中部、前部的温差。为了防止喷嘴流涎，喷嘴温度可以比表中所示的温度低10℃，如果要流动性的话，所设温度可以比表中所示的温度高出20℃，但是必须注意下列情况。料筒温度时：滞留时间过长，不会引起粒料在料筒中老化，也不会产生腐蚀性气体，所以滞留时间长一般不会产生什么大的问题。但是，如果长时间中断成型的话，请料筒温度，再次成型时，以扔掉几模为 美国rtp 、lcp 3400 fc-110、lcp 3400 fc-120、lcp 3400 fc-130、lcp 3400 fc-210

lcp the compression pressure / holding time is the best appearance&size control for the plastic parts,&the pressure holding time plays an important role. in theory, the holding time is the time needed to solidify the gate. compared with other engineering plastics, pa46 usually requires only a very short holding time due to its rapid solidification characteristics. it can reduce the sag&hole caused by the volume contraction through the long enough pressure protection stage. however, the pressure protection should not be too high to oid the stress. one way to determine the correct pressure level is to increase the pressure pressure until the depression is not seen. after the complete cooling, it is cut at the thickest part of the plastic part to check if there is a hole. if necessary, the pressure protection pressure can be increased. one way to determine the holding time is to measure the weight of the plastic part,&then increase the holding time until the constant weight is obtained. a more complex approach is to install sensors in the city to determine the exact setting time of the gate. compared with pa66, pa46 needs only about half of the holding time. this combined with its higher mold temperature can explain why pa46 has a shorter period of time than other engineering plastics.
