cycles, in every cycle: −40 to 130°C, 10°C/h, the highest and lowest temperatures were maintained for 4 h, room temperature was maintained for 2 h.PA6 can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor. where S L is the shrinkage ratio of the injection molded products, L m is the mold cavity size (the real size after considering the shrinkage volume compensation of 0.5%), and L p is the size of the injection molded products. From the aforementioned comparisons, it can be concluded that the dimensional accuracies of the undried parts treated by route II are the highest for the peripheral dimensions and the diameter of the central hole. Nevertheless, its corresponding dried part can also basically meet the accuracy requirements. But in the usage of the plate, moisture should be prohibited to ensure its insulating and antibreakdown properties; hence, re-drying after the boiling water bath is recommended. 4.2 Mechanical property improvements of the plate treated by the three routes

Some conclusions are presented here. Data availability statement: The datasets generated during and/or analyzed during the current study are available from the corresponding author on reasonable request. The tensile fractured surfaces of the samples treated by the three routes were coated with gold to prevent electrical charging. The surface morphological images of all samples were observed by using scanning electron microscopy (SEM; Sigma 300, Germany) at an acceleration voltage of 5.0 kV. 4 Results and discussion 4.1 Dimensional accuracies of the plate treated by the three routes The structural characterization of the plates (untreated and treated by the three routes) were carried out by X-ray diffraction (XRD, D/max-2500/PC, Japan). Data were collected over the range 2 θ = 10–40° in the fixed time mode with a step interval of 0.02.
