Cómo funciona el plegado de metales?

El plegado de metales es un método crucial en la fabricación de metales que consiste en deformar el metal para darle la forma deseada aplicando fuerza, normalmente con una prensa plegadora o una máquina similar. Este proceso permite un conformado preciso a lo largo de una línea recta para crear formas como curvas en V, en U o en canal en chapas metálicas. La técnica puede variar desde métodos manuales hasta avanzados sistemas CNC (control numérico por ordenador), que ofrecen mayor precisión y repetibilidad. 

Esta técnica de plegado de metales se utiliza ampliamente para producir piezas resistentes y funcionales de forma eficaz. Se emplea habitualmente para crear componentes que van desde pequeños soportes hasta grandes elementos arquitectónicos. Con la evolución de la tecnología CNC, las tareas de plegado complejas y de alta precisión son ahora más factibles, lo que ofrece una mayor flexibilidad de diseño y ciclos de producción más rápidos. Los sistemas CNC son especialmente beneficiosos para la producción en serie, ya que reducen al mínimo las variaciones y garantizan una calidad uniforme en grandes lotes.

Control de calidad y pruebas certificadas

In our metal bending services, quality control is a very strict process that involves all the bent metal parts to fit precisely to the dimension and functionality specifications. The individual components are checked with calibrated instruments and coordinate measuring machines (CMM) to ensure the accuracy of the bend angles, size and accuracy of the whole component. This guarantees quality in a prototype and production run even in a tight-tolerance application.

Bent metal components are all checked against GD&T specifications and also ISO and ASME standards to ensure that they meet design specifications. In case of projects that need surface finishes, further testing is used to evaluate the coating thickness, adhesion, and appearance which will ensure durability and similar quality of finish when bending.

We are fully traceable by offering full documentation with material certificates, inspection reports and quality records. This open practice helps customers to trust in the quality, consistency and certified quality of our metal bending services.
