Aplanado y alisado en caliente
A menudo, los tratamientos térmicos pueden deformar o doblar las aleaciones utilizadas para fabricar piezas importantes que deben ser planas para encajar sin problemas.
Aplanamiento experto para obtener mejores piezas.
Durante la fabricación de metales, los materiales planos y enderezados son fundamentales para un ajuste y una soldadura correctos. El tratamiento térmico y el enfriamiento pueden dejar las piezas ligeramente deformadas e incapaces de encajar correctamente. Paulo utiliza una variedad de procesos para enderezar y aplanar aleaciones utilizando maquinaria controlada por ordenador y supervisada por nuestros expertos metalúrgicos para ofrecer resultados limpios y consistentes para cada pieza, cada vez.
Servicios de alisado y aplanado de Paulo
Enderezamiento mecánico
Se utilizan herramientas manuales y prensas para enderezar las piezas después del tratamiento térmico. Se utilizan calibradores u otros dispositivos de medición para verificar que las piezas cumplen los requisitos de rectitud.
Aplanamiento en caliente
Las piezas se sujetan entre grandes matrices y se calientan para conseguir la planicidad.
El borde de Paulo.
La distorsión es a menudo inevitable en los tratamientos térmicos. Nuestros equipos e instalaciones de última generación nos permiten realizar trabajos de enderezado y aplanado de gran volumen para garantizar que sus piezas funcionen para el fin previsto. Nuestras prensas manuales e hidráulicas pueden aplanar hasta 100 toneladas, con accesorios de aplanado y sujeción para piezas de hasta 36 pulgadas de diámetro. También utilizamos una enderezadora de 19 rodillos para piezas de hasta 0,5 pulgadas de grosor y grandes hornos controlados por ordenador para múltiples dispositivos de sujeción.
Flattening and Straightening FAQs
Can you fix warpage or distortion that happens during heat treatment?
Yes. Some level of distortion is inevitable during heat treatment due to the metallurgical transformations and thermal expansion/contraction that occur during the process. Paulo offers several solutions to bring parts back into specification:
Mechanical straightening uses a manual and hydraulic presses (up to 100 tons of capacity) combined with precision gauges and measurement devices to verify parts meet your straightness requirements.
Hot flattening is our primary method for correcting distortion in flat components. Parts that come out of heat treatment with as much as 0.025″ of variance can often be brought back within 0.010 – 0.015″ using our clamp and temper process. We can achieve flatness within 0.010″ (ten thousandths of an inch) for many applications.
Is there any risk to flattening or straightening my parts?
With straightening, there is an inherent risk because you’re applying bending force to heat-treated (hardened) material. Our operators use careful techniques and years of experience to minimize this risk, but it’s important to understand that the possibility of cracking exists, particularly with certain geometries or highly hardened materials.
Hot flattening carries significantly lower risk because the process works by relieving stresses rather than forcefully bending the material. During hot flattening, parts are clamped flat and then heated to a tempering temperature that allows the material to relax into its flattened position. This makes it a safer, more controlled process—especially for production volumes.
What types of parts are best suited for flattening?
Our hot flattening services are ideal for higher-volume production of flat components where consistency and repeatability are critical.
Ideal part characteristics include:
- Flat parts under ¼” thick (though dimensions can vary)
- Components up to 36″ in diameter
- Production quantities where systematic processing delivers efficiency
Common applications that are best suited for flattening:
- Fáseres de leva
- Componentes del embrague de transmisiones automáticas y manuales
- Herramientas
- Brackets and spacers
- Metal stampings requiring precise fit or weld alignment
- Componentes de montaje de asientos para automóviles
What's the difference between flattening and straightening?
While both processes correct warpage that occurs during heat treatment, they work differently. Straightening is a manual process where hydraulic presses are used to apply targeted pressure to specific areas of a part, carefully bending it back to specification. Parts must actually be bent past straight to spring back to the correct position when pressure is released.
Hot flattening (also called clamp and temper) is a more systematic process ideal for higher volumes of flat components. Parts are stacked between large flat plates, clamped together, and heated to relieve internal stresses. When unclamped, the parts retain their flat shape. This works particularly well for relatively thin, flat components like cam phasers, clutch components, brackets, and spacers under ¼” thick and up to 36″ in diameter.
