锁模力 Clamping Force精密注塑的另一个重要因素是锁模力。 原因是： 模腔更好的排气 (90%的空气从分型面排出) 减少机器和模具的磨损 节省能源One other important aspect for precise injection molding is the clamping force. Reasons for that are: Much better venting of the cavities during injection. (ca. 90% of the air inside the cavity escape over the parting line) To prevent machine and mold from unnecessary wear. Saving energy

锁模力 Clamping Force怎样计算锁模力锁模力 = 单位锁模力 X (产品投影面积 + 流道投影面积)

如果有滑块，需要将滑块投影面积的 30% 加入产品投影面积

How to calculate the clamping force ?clampingf orce specif icclampingf orce (projectedarea of all molded part proj. area sprue)

If the mold contains sliders! You have to add 30% of the projected slider area to the projected area of molded part.

选择注射单元规格的准则 Criteria to Select the Injection Unit注射单元的欧洲橡塑机械协会 (EUROMAP)规格表示注射单元的最大注 射功。计算方法最大注射压力 X 最大行程容量 / 1000 举例 按注塑机 320 C 600-250 规格表 最大注射压力(35 mm 螺杆): 1820 bar 最大行程容量 144 ccm 1820 bar X 144 ccm /1000 250

The size of the injection unit is according to EUROMAP and indicates the working performance of the injection unit.The working performance is calculatemax. spec. injection pressure x max. stroke volume / 1000 Example:

According to the technical data of 320 C 600-250 Max. Injection pressure (screw diameter 35mm) = 1820 bar Max. Stroke volume = 144 cm31820 bar x 144 cm3 / 1000 250
