PLA Injection Grade Modified Application
Problem Phenomenon
Pure PLA injection applications are limited, and modification significantly expands the application range
Cause Analysis
Pure PLA has high transparency and high gloss but is hard and brittle, difficult to process, and not heat-resistant; modified resins (toughening, heat-resistant, high crystallization) sacrifice transparency for processing and application performance, and are the mainstream of injection applications
Solution
①Injection applications prioritize modified PLA grades; ②Select the modification system per toughness, heat resistance and crystallization needs; ③Evaluate modification losses for transparency requirements; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Modified PLA is the realistic answer for injection applications; pure PLA's transparency advantage must yield to performance in most scenarios; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
