1. Solve the influence of injection molding machine and mold elements

　　要選擇與注（zhù）塑加工容量相當的注塑機，如果注塑機有材料死角等問（wèn）題，還是（shì）替換設備比較好。模具澆注係統、排氣槽等色差的原因可以（yǐ）通過對應部分的模具的維護模具來。須先設備和模（mó）具的問（wèn）題，才能組織生產，減低問題的複雜性。

　　Choose an injection molding machine with the same processing capacity as the injection molding machine. If the injection molding machine has problems such as material dead corner, it is better to replace the equipment. The causes of color difference such as mold gating system and exhaust slot can be solved by maintaining the mold of the corresponding part. We must solve the problems of equipment and molds before we can organize production and reduce the complexity of the problem.

　　2、原料樹脂、色母（mǔ）的影響（xiǎng）

　　2. Solve the influence of raw resin and color masterbatch

　　在生產淺色（sè）產品的情況下，不能忽視原料樹脂的（de）差異對產品色調變動的（de）影響。

　　In the case of producing light color products, the influence of the difference of raw resin on the color change of products cannot be ignored.

　　3、混合不均的影響

　　3. Address the impact of uneven mixing

　　注（zhù）塑加工材料和色母的混合不好，產品的顏色就會變（biàn）化無常（cháng）。和色母機械均勻混合後，用下（xià）吸引材料送入料（liào）鬥，在靜電的作用下色母和料鬥分離，容易吸（xī）附在（zài）料鬥壁上（shàng），射出（chū）循環（huán）中的色母的（de）量發（fā）生變化，產生色差。濟南注塑加工

　　If the injection molding materials and color masterbatch are not mixed well, the color of the product will be changeable. After evenly mixed with the color masterbatch machine, the lower suction material is sent to the hopper. Under the action of static electricity, the color masterbatch is separated from the hopper, which is easy to be adsorbed on the hopper wall, and the amount of color masterbatch in the injection cycle changes, resulting in color difference.

　　4、減（jiǎn）少汽缸溫度對色差（chà）的影（yǐng）響

　　4. Reduce the influence of cylinder temperature on color difference

　　在生產中，由於（yú）某加熱線圈的破損故障或（huò）加熱控製部分的失控引起的汽缸溫度的急劇變化，經常會產生色差。

　　In production, the color difference often occurs due to the sharp change of cylinder temperature caused by the damage fault of a heating coil or the out of control of heating control part.

　　這種原因引起的色差很容易判定（dìng），但一般加熱線圈的破損故障在發生色差時會導致塑（sù）化不均勻現象，加熱控製部分的失控經常會伴隨產品的紅斑、嚴重（chóng）變色、錫化（huà）現（xiàn）象。因此（cǐ），在生產中須經常檢查加（jiā）熱部（bù）分，如果加熱（rè）部分破損或（huò）失控，要（yào）及時替換修理（lǐ），減少這（zhè）種色差的發生（shēng）概率。

　　The color difference caused by this reason is easy to determine, but the damage fault of the general heating coil will lead to uneven plasticization in case of color difference. The out of control of the heating control part will often be accompanied by product erythema, serious discoloration and tinning. Therefore, the heating part shall be checked frequently in production. If the heating part is damaged or out of control, it shall be replaced and repaired in time to reduce the occurrence probability of this color difference.

　　5、減少注塑過程調整時的影響（xiǎng）

　　5. Reduce the influence of adjustment in injection molding process

　　如果（guǒ）因為色差（chà）以外的原因需要調整注塑加工工藝（yì）參數，如果盡可能不改變注塑溫度、背壓、注（zhù）塑周期和色母的添加量，還須觀察工（gōng）藝參數的變化對色差的影響。

　　If the injection molding process parameters need to be adjusted for reasons other than color difference, if the injection temperature, back pressure, injection cycle and the addition amount of color masterbatch are not changed as much as possible, the influence of the change of process parameters on color difference must also be observed.

　　盡量免除高注（zhù）塑速度、高背（bèi）壓等引起強剪切（qiē）作（zuò）用的注塑過程，以免因局部過熱（rè）和貪婪等因素（sù）引起的色差（chà）。嚴格控製汽缸各加熱部的溫度，尤是噴嘴和靠近噴嘴的加熱（rè）部。

　　Try to avoid the injection process with strong shear caused by high injection speed and high back pressure, so as to avoid the color difference caused by local overheating and greed. Strictly control the temperature of each heating part of the cylinder, especially the nozzle and the heating part close to the nozzle.

　　6、掌握汽缸溫度、色母量的影響

　　6. Master the influence of cylinder temperature and color masterbatch quantity

　　在進行色差調整之前，有需要（yào）知道產品的顏色根據溫度、色（sè）母（mǔ）量而變化的傾向。不同顏色的（de）母親根（gēn）據生產的（de）溫度和（hé）顏色的母親的量，其注塑加工的產品（pǐn）顏色變化規律（lǜ）不同。可以通過嚐試顏色來決定變化規律。

　　Before adjusting the color difference, it is necessary to know that the color of the product changes according to the temperature and the amount of color masterbatch. According to the production temperature and the amount of color mother, the color change law of injection molding products is different. You can determine the change law by trying color.
