成型温度对PP和ABS试样表面颜色和光泽度的影响

以K31皮纹为例,研究了成型温度对聚丙烯(PP)和丙烯腈-丁二烯-苯乙烯塑料(ABS)试样表面颜色和光泽度的影响。结果表明,随着模具温度和熔体温度的升高,无论是PP还是ABS,其试样颜色的L值均呈增加趋势而光泽度均呈降低趋势,且ABS试样的光泽度降低程度比PP试样高。注塑温度和模具温度升高,材料的流动性提高,冷却时间延长,试样复制模具皮纹的能力提高,使得PP和ABS试样表面皮纹深度均有所增加,从而使试样的光泽度降低、同时L值升高。与PP结晶型材料不同,ABS作为非结晶型材料,其流动性受温度影响更为显著,随着成型温度的升高,使得ABS试样的光泽度降低的程度更大。

Effects of mold cavity temperature on surface quality and mechanical properties of nanoparticle‐filled polymer in rapid heat cycle molding

Acrylonitrile‐butadiene‐styrene (ABS)/poly methyl methacrylate (PMMA) and ABS/PMMA/nano‐CaCO₃ composites were prepared in a corotating twin screw extruder. Single‐gate and double‐gate samples were molded based on a rapid heat cycle molding (RHCM) system. Effects of mold cavity temperature on surface quality and mechanical properties of single‐gate and double‐gate samples in RHCM process were conducted. The results showed that surface quality of plastic parts can be improved significantly by increasing mold cavity temperature. Nano‐CaCO₃ particles on the surface of plastic parts can be eliminated by using high mold cavity temperature. The roughness and gloss of two kinds of plastic parts (ABS/PMMA and ABS/PMMA/nano‐CaCO₃) stabilized at the same level when the mold cavity temperature is above glass transition temperature of resin material. Weld line can be eliminated in RHCM process during high mold cavity temperature. The tensile strength of both ABS/PMMA and ABS/PMMA/nano‐CaCO₃ exhibited decreasing trend with the increase of mold cavity temperature. Reduction of internal stress gave rise to the increase of Izod impact strength of ABS/PMMA for both sing‐gate and double‐gate samples. However, influence regularity of mold cavity temperature on Izod impact strength of ABS/PMMA/nano‐CaCO₃ is depended on the number of gates. For all the samples in this study, too high of mold cavity temperature (higher than 125°C) deprave Izod impact strength of plastic parts. Both ABS/PMMA and ABS/PMMA/nano‐CaCO₃ are not susceptible to weld line. When the mold surface temperature is approximately equal to glass transition temperature of resin material, all the samples are found to give the best combination of properties. © 2014 Wiley Periodicals, Inc.

Shrinkage behavior and optimization of injection molded parts studied by the taguchi method

Shrinkage behavior of a plastic plays a critical role in determining the final dimensions of an injection‐molded part. It is well known that process conditions affect many properties of plastic parts, including shrinkage. This study applies the Taguchi method to systematically investigate the effects of process conditions on the shrinkage (along‐ and across‐the‐flow directions) of three plastics: high‐density polyethylene (HDPE), general‐purpose polystyrene (GPS), and acrylonitrile‐butadiene‐styrene (ABS). The results show that HDPE, a semicrystalline plastic, shrinks more than GPS and ABS, two amorphous materials. The extent of anisotropic shrinkage in the along‐the‐flow and across‐the‐flow directions for HDPE is different from GPS and ABS. More shrinkage occurs in the across‐the‐flow direction of HDPE than in its along‐the‐flow direction. The reverse is true for GPS and ABS. Mold and melt temperatures, along with holding pressure and holding time, are the most significant influences on the shrinkage behaviors of three materials, although the importance of each is different for each plastic. The optimal conditions for reducing shrinkage identified by the Taguchi method are experimentally verified and validated by t‐statistic tests. The prediction matches very well with the experimental value for the along‐the‐flow shrinkage of GPS.
