Controlling Crystallinity in Injection Molded PLA

Currently, use of PLA for injection molded articles is limited for commercial applications because PLA has a slow crystallization rate when compared with many other thermoplastics as well as standard injection molding cycle times. The overall crystallization rate and final crystallinity of PLA are controlled by the addition of physical nucleating agents as well as optimization of injection molding processing conditions [4].

The development of different microstructures because of the applied thermomechanical conditions during injection molding depends upon the operative parameters involving melt processing temperature, mold temperature, 

4 Porous Lamellar Poly (Z-Lactic Acid) Scaffolds Made by Conventional Injection Molding Process 

The 50/50 wt% PLLA and PEO was compounded in a tumbler mixer in solid form and put into the hopper. The lamellar structure is developed by injection molding of the blend above the melting temperature of PLLA and PEO, and the
