時(shí)間
完成一次注射過(guò)程所需的時(shí)間稱為成型周期。成型周期包括充模時(shí)間、保壓時(shí)間、冷卻時(shí)間和其他時(shí)間（開(kāi)模、脫模、閉模等），直接影響勞動(dòng)生產(chǎn)率和設(shè)備利用率。TPU的成型周期通常決定于硬度、制件厚度和構(gòu)型，TPU硬度高周期短，塑件厚周期長(zhǎng)，塑件構(gòu)型復(fù)雜周期長(zhǎng)，成型周期還與模具溫度有關(guān)。TPU成型周期一般在20~60s之間。
注射速度
注射速度主要決定于TPU制品的構(gòu)型。端面厚的制品需要較低的注射速度，端面薄則注射速度較快。
螺桿轉(zhuǎn)速
加工TPU制品通常需要低剪切速率，因而以較低的螺桿轉(zhuǎn)速為宜。TPU的螺桿轉(zhuǎn)速一般為20~80r/min，則優(yōu)選20~40r/min。
