A bigger shift toward PLA in injection molding has been slowed by serious processing issues. There are several challenges that convertors have faced when processing injection molded PLA parts, especially when using existing equipment and tools, including:
Due to these issues, processing PLA was not even possible in many cases – until now.
A Release Agent facilitates the separation of the cured part from the mold. SUKANO® Mold Release Masterbatch migrates to the surface of the final product facilitating demolding of the injection molded part from the metal surface of the cavity, hence reducing the demolding force.
Customer cases have demonstrated that the switch from fossil-based plastics to PLA for injection molding is very much possible, all without major financial investments.
SUKANO ® Mold Release Masterbatches can reduce the friction between the polymer chains. This leads to a lower melt viscosity and therefore a higher melt flow without increasing the temperature. This can help to fill the cavities, especially in thin wall applications.
