First of all, in the production of extruded PEEK sheets or PEEK rods, it is more common to select the performance parameters of raw materials, especially the melting point of the raw materials, which involves the flatness of the extruded sheet surface and the roundness of the round bars. High temperature will increase the difficulty of controlling the thickness/flatness/roundness/straightness of extrusion molding, while the profiles made with lower melting point are difficult to have better performance guarantee in terms of performance, so appropriate raw materials The melting point has a great relationship with the control of the forming and size control of the extruded profile; Secondly, whether the supporting parts Read more
