injection molded plastic for LFRT materials
PA66/PA6/PP/PBT/PPS/TPU with long glass/carbon fiber
ISO9001, SGS, CTI, ROHS
LKM Mould Base
rmoplastic resin in LFT has a large viscosity and contains long glass fibers, so flowability of injection molding is poor. In order to improve fluidity of LFT, method including increasing gate and diameter of runner, increasing injection-pressure, increasing temperature of cylinder and temperature of mold, and dispersibility of fiber can be improved by control of back pressure of screw. During injection molded plastic for LFRT materials process, fibers will be damaged to some extent due to shearing. Fiber breakage can be reduced by adjusting size of gate and runner and associated process conditions.
injection-molded plastic for LFRT materials generally uses an injection-molding machine with a clamping force of more than 100 tons. cylinder and screw should be treated with wear resistance. If possible, better to use bimetallic carbide steel. In general, actual injection-volume should be 40%-60% of machine's maximum injection-capacity.
biggest problem in whole process of injection molded plastic for LFRT materials is that appearance is not beautiful. solution points are mold temperature and holding time.
Since fiber in LFT material is much longer, if exposure has a great influence on appearance, it is necessary to increase mold temperature of surface and reduce mold temperature of back surface, so that base material PP flows to appearance surface, and glass fiber is deposited on back surface, reby achieving good appearance requirements.
