【正文】 Printed: 12/2/2020 壓力轉(zhuǎn)換系數(shù) ：一般在注塑機(jī)上或者說明書上可以找到類似右側(cè)的壓力 圖表，可以看出對(duì)應(yīng)不同的螺桿直徑有相應(yīng)不同的斜線，這也說明壓力的轉(zhuǎn)換是基于機(jī)器所使用的螺桿的直 徑。 有效壓力 是指實(shí)際作用于螺桿前端塑料上的壓力 如何進(jìn)行有效壓力與液壓壓力的轉(zhuǎn)換： Specific pressure is the actual pressure on the plastic material in front of the screw. 有效壓力是指實(shí)際作用于螺桿前端塑料上的壓力。 注塑機(jī)設(shè)定手冊(cè) Prepared/by: Updated/by: Version
