WPC （wood plastic composites） are a young generation of composites with rapidly growing usage within the plastics industry. The advantages are the availability and low price of the wood particles, the possibility of partially substituting the polymer in the mixture and sustainable use of the earth＇s resources. The current WPC products on the market are to a large extent limited to extruded products. Nowadays, there is a great interest in the market for consumer products in more use of WPC as an alternative to pure thermoplastics in injection mold.ng processes. This work presents the results of numerical simulation and experimental visualization of the mold.filling process in injection mold.ng of WPC. The 3D injection mold.ng simulations were done with the commercial software package Autodesk~ mold.low Insight 2016 （AMI）. The mold.filling experiments were conducted with a box-shaped test part. In contrast to unfilled polymers, the WPC has reduced melt elasticity so that the fountain flow often does not develop. This results in irregular flow front shapes in the mold.d part, especially at high filler content.

High productive technique for polishing free surface with elastic ball type wheel on grinding center

引用

Journal of Shanghai University(English Edition) 2007年第6期11卷 603-606页

作者：吴晓君孙树栋 Department of Mechanical Engineering Xi'an University of Architecture and Technology Department of Mechanical Engineering Northwestern Polytechnical University

Polishing is an important finishing process in die and mold.manufacturing. Hand polishing takes long time and much labor. Efforts are made to automate the polishing process while keeping accuracy. Recently grinding centers have been developed, which are used for free surface polishing in the present work. The new polishing technique applies the same cutting locus as used in the cutting process to remove only cusp height effectively, keeping the form accuracy generated in the cutting process.

关键词： polishing free surface grinding center ball type wheel die mold.
