Verfahren zur Herstellung einer Düsenplatte mit zwischen Grundkörper und Schneidkörper eingelagerter Zwischenschicht

摘要

The jet plate, for the granulation of plastics under water,has at least one intermediate layer (13) of a metal powder mixt. with a nickel content, at a layer thickness of 0.5-2.0 mm to compensate for generated heat tensions. The intermediate layer (13) is compressed in a hot isostatic press action and is formed as a hard material alloy by diffusion welding over the whole surface of the base body (2) with the included jets (6) and bonded to the cutting plate (12) for wear protection. The structure gives a jet plate without joints and prevents damage to the cutting plate from thermal tension.
