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.
