Plastic sprayer was very difficult to find at the beginning of the epidemic, because most factories went to make non-woven masks, which was very profitable in early 2020. At that time, I was a fresh worker in foreign trade industry. Although I have changed careers now, I am still impressed. Okay, having said that, let's get back to the theme, have you noticed the color difference when using the injection molding machine for plastic sprayer?

Color difference of plastic sprayer in the injection molding process

Chromatic aberration is a common defect in injection molding. It is not uncommon for injection molding machines to be scrapped in batches due to color differences in matching parts. There are many factors affecting chromatic aberration, involving raw material resin, color masterbatch (or toner), mixing of color masterbatch and raw materials, injection molding process, injection molding machine, mold, etc. Because of the wide range of involvement, color difference control technology is also recognized as difficult in injection molding. Master one of the techniques. In the actual production process, we generally control the color difference from the following six aspects.

Six tips to control the color difference of plastic sprayer in injection molding 

1. Eliminate the influence of injection molding machine and mold factors

Choose an injection creating maker along with a capability substitute to that of the plastic sprayer. If the injection creating machine has issues like material stumbling blocks, the banned expressions must be actually switched out. The colorful aberration brought on by the mold and mildew putting system, exhaust canal, etc can be fixed through repairing the matching portion of the mold. The issue of injection creating machine and mold and mildew need to be addressed initially just before production could be arranged to decrease the complexity of the concern.

2. Along with the effect of basic material substance and colour masterbatch

Controlling raw materials is the key to entirely resolving colorful difference. As a result, particularly when generating light-colored plastic sprays, the evident effect of the various thermic reliability of the raw product substance on the different colors fluctuation of the product can easily not be overlooked.

In view of the reality that the majority of treatment creating manufacturers carry out certainly not produce plastic masterbatch or even color masterbatch on their own, the focus of attention could be put on production administration and also resources assessment. That is to boost the assessment of basic materials storage space; the very same item in the development is actually generated due to the same maker, the very same company of masterbatch, and colour masterbatches;

For the colour masterbatch, our company need to conduct random inspections prior to mass production. Both the same proofreading and contrast in this particular time. If the shade is very little different, it could be taken into consideration trained. Equally as the batch of different colors masterbatch has a slight different colors variation, Use the different colors masterbatch after remixing to reduce the color difference dued to unequal mixing of the shade masterbatch itself. Together, our experts also require to concentrate on assessing the thermal reliability of the raw resin as well as shade masterbatch For those with unsatisfactory thermal reliability, we advise that the supplier substitute them.

3. Remove the influence of jagged blending of masterbatch as well as masterbatch.

Poor mixing of plastic masterbatch as well as color masterbatch will likewise produce the item shade improvement transient. After the masterbatch as well as shade masterbatch are robotically mixed as well as delivered in to the hopper by means of the reduced suction material, the color masterbatch is split coming from the masterbatch as a result of static electrical energy and also is actually simply adsorbed on the receptacle wall. This are going to definitely lead to the modification in the quantity of different colors masterbatch during the treatment pattern, causing Chromatic deviance.

In this case, the raw products could be sucked in to the hopper and then manually stirred. For the production of tinted items by including skin toner, the most reliable method is to use a warm air dryer instead of a suction machine to prevent the different colors variation dued to separation of the printer toner coming from the expert set.

4. Lessen the influence of shot molding method correction

When the treatment molding process parameters require to be adjusted for non-chromatic difference causes, do not transform the shot temperature level, back tension, injection cycle and also the volume of masterbatch added as long as possible. The change additionally requires to note the effect of procedure guideline improvements on the different colors and also radiance. If shade aberration is actually discovered, it should be actually adjusted over time.

Make an effort to stay clear of the use of higher treatment speed, high back pressure as well as other injection creating processes that lead to solid shear to stop shade distinction dued to local overheating or thermic decomposition. Strictly regulate the temp of each heating system section of the gun barrel, particularly the nozzle and the heating component near to the nozzle.

If your injection molding machine is producing a plastic sprayer or other plastic products, you can effectively control the color difference by implementing the above methods. If you have other questions, we are also gald to answer you. If you want to invest in an Injection molding machine for plastic sprayer, we can provide you with a good solution. We provide customers with high-speed, high-efficiency, high-precision and high-energy-saving injection molding machines.
