TOKIO, 15 de julio de 2021 /PRNewswire/ -- Polyplastics Co., Ltd., un proveedor líder mundial de termoplásticos de ingeniería, ha desarrollado un método de prueba que identifica la formación de gas durante el proceso de moldeo por inyección y ayuda a reducir los depósitos de moho. El método de investigación de gas en moldeo por inyección (GIMIM) de la empresa facilita el moldeo continuo y mejora la eficiencia de la producción.

Durante el proceso de moldeo por inyección, las duras condiciones (alta temperatura, alta velocidad) y el deterioro de los aditivos plásticos pueden liberar grandes volúmenes de gases de descomposición. Los depósitos de moho, las quemaduras de gas y los disparos cortos causados por el gas de pirólisis pueden provocar problemas de calidad, incluidos efectos no deseados en las dimensiones y la apariencia de los productos, lo que da como resultado una mayor tasa de defectos. Mantener operaciones de producción altamente eficientes es importante mientras los fabricantes trabajan para cumplir con las complejas aplicaciones actuales, como la electrificación y la automatización automotrices.

El método patentado de Polyplastics captura y evalúa los gases formados durante el moldeo e identifica el mecanismo por el cual se forma el gas de pirólisis durante el moldeo por inyección. El innovador método patentado atrapa gases de acuerdo con métodos basados en moldes, utiliza espectrómetros de masas de cromatografía de gases (GC/MS) para analizar cualitativa y cuantitativamente su composición, identifica los gases que se forman y realiza mejoras fundamentales en las fuentes de su formación.

Esta configuración simple del sistema se divide en las tres etapas de plastificación, medición e inyección, y cada unidad está equipada con trampas de gas para aislar los gases que se forman dentro de cada parte del proceso. GIMIM puede reflejar las circunstancias reales durante el moldeo atrapando y analizando directamente los gases formados durante el moldeo.

GIMIM permite medir sustancias de alto peso molecular que pueden provocar depósitos de moho. Dado que este método analiza directamente los gases que se forman dentro del molde durante el llenado, la compañía cree que produce resultados que se acercan más a las condiciones del mundo real. En investigaciones posteriores, Polyplastics planea examinar otros problemas causados por el gas de pirólisis, como inyecciones cortas y defectos de quemado por gas, así como depósitos de moho.
