1、解決注塑機及模具要素的影響
1. Solve the influence of injection molding machine and mold elements
要選擇與注塑加工容量相當?shù)淖⑺軝C，如果注塑機有材料死角等問題，還是替換設備比較好。模具澆注系統(tǒng)、排氣槽等色差的原因可以通過對應部分的模具的維護模具來解決。須先解決設備和模具的問題，才能組織生產，減低問題的復雜性。
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、解決原料樹脂、色母的影響
2. Solve the influence of raw resin and color masterbatch
在生產淺色產品的情況下，不能忽視原料樹脂的差異對產品色調變動的影響。
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、解決混合不均的影響
3. Address the impact of uneven mixing

注塑加工材料和色母的混合不好，產品的顏色就會變化無常。和色母機械均勻混合后，用下吸引材料送入料斗，在靜電的作用下色母和料斗分離，容易吸附在料斗壁上，射出循環(huán)中的色母的量發(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、減少汽缸溫度對色差的影響
4. Reduce the influence of cylinder temperature on color difference
在生產中，由于某加熱線圈的破損故障或加熱控制部分的失控引起的汽缸溫度的急劇變化，經(jīng)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，但一般加熱線圈的破損故障在發(fā)生色差時會導致塑化不均勻現(xiàn)象，加熱控制部分的失控經(jīng)常會伴隨產品的紅斑、嚴重變色、錫化現(xiàn)象。因此，在生產中須經(jīng)常檢查加熱部分，如果加熱部分破損或失控，要及時替換修理，減少這種色差的發(fā)生概率。
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
5. Reduce the influence of adjustment in injection molding process
如果因為色差以外的原因需要調整注塑加工工藝參數(shù)，如果盡可能不改變注塑溫度、背壓、注塑周期和色母的添加量，還須觀察工藝參數(shù)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.
盡量免除高注塑速度、高背壓等引起強剪切作用的注塑過程，以免因局部過熱和貪婪等因素引起的色差。嚴格控制汽缸各加熱部的溫度，尤是噴嘴和靠近噴嘴的加熱部。
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，有需要知道產品的顏色根據(jù)溫度、色母量而變化的傾向。不同顏色的母親根據(jù)生產的溫度和顏色的母親的量，其注塑加工的產品顏色變化規(guī)律不同?？梢酝ㄟ^嘗試顏色來決定變化規(guī)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.
