ABSTRACT:
In this study two molds were designed and used in MuCell_technology to generate implants with a porous structure. To arrive the desiredpore structure many process parameters were investigated for indicating theeffects of process parameters on the pore morphology. This process parameterinvestigation was performed on each mold respectively, so that the influencesof the mold design on the pore morphology have been researched by the sameprocess parameter setting. It was found that the mold design also had effectson the pore structure in MuCell_ technology. A proper mold design couldimprove the generated pore structure, such as porosity, pore diameter, andinterconnectivity.
KEY WORDS: mold design, cell morphology, MuCell_, injection molding,medical implant, porous polymer, polyurethane.
摘 要
在这项研究中，两副模具都用微孔泡沫注塑技术MuCell设计和使用以生成具有多孔结构的植入物。为了到达所需孔隙结构，对许多工艺参数进行了调查用以说明工艺参数对孔形态的影响。这个过程参数的调查分别在每个模具上进行严格地实验，这样模具设计对孔形态的影响可以通过相同工艺参数设置来研究。于是研究发现，模具的设计对MuCell技术的孔隙结构确有影响。一个适当的模具设计能提高生成的孔隙结构，比如孔隙率，孔径等，并且互相影响。
