PMMA Welding Process
Fenómeno do problema
PMMA welds have insufficient strength, and visible weld seams affect transparent appearance
Análise das causas
PMMA can be welded by hot knife, hot gas, ultrasonic, or spin welding; molecular bonding and stress state at the weld determine strength; transparent parts have high requirements for optical treatment of weld seams
Solução
①Select a suitable welding process according to the structure; ②optimize welding parameters to ensure sufficient fusion; ③polish weld seams after welding for transparent parts; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PMMA has good weldability, but weld seam management is delicate work; process selection and post-weld treatment are equally important; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
