pp moldingcharacteristics: 1. crystalline material, hygroscopicity is small,easy to happen melt break, long-term contact with hot metal easy todecompose. 2. good fluidity, but shrinkage range and shrinkagevalue, prone to occur shrinkage hole. dents, deformations. 3.cooling speed, pouring system and cooling system should be slowlycooling, and pay attention to control molding temperature.materials tend to be oriented at low temperature and high pressure,mold, temperature less than 50 degrees, plastic parts are notsmooth, easy to produce bad fusion, flow marks, 90 degrees or moreprone to warpage deformation. 4. plastic wall thickness must beuniform to avoid lack of glue, sharp angle, to prevent stressconcentration. ] pp properties overview: 1, density pp is allsynthetic resin medium density, small. pp plastic products can beadded only main and auxiliary antioxidants, without the need to addultraviolet absorbent. 2. the tensile strength and rigidity ofmechanical properties of pp are good, but the impact strength isbad, especially at low temperature. in addition, if there isorientation or stress during the molding process, the impactstrength will be significantly reduced. although the impactstrength is poor, after being filled or reinforced, its mechanicalproperties can compete with the engineering plastics with high costin many fields. 3, surface hardness pp surface hardness in fivegeneral purpose plastics is low, only better than pe. when thecrystallinity is higher, the hardness is also increased, but stillless than pvc, ps, abs and so on. it has good electricalinsulation.
