Editing Correction fluid (section)

== Manufacture ==

Stainless steel tanks are used to hold {{convert|3,000|gal}} or more. Specialists must consider the mixer and temperature control system carefully, and also the formula instructions, the correct types, and the amounts of raw materials at specified times by using computer controls. This process consists of 3 methods: firstly, compounding the batch; secondly, quality control check; and thirdly, filling and packing.<ref name=":0">{{cite web|url=http://www.madehow.com/Volume-4/Correction-Fluid.html#ixzz5B3imY5kO|title=How Products Are Made.

In the first phase, water will be filled into the main batch tank. The suspending agents and some of the ingredients will be added in this phase. Mixing is implemented at low rate for adequate dispersion. During the mixing, there is no air added into the mixture. In the second phase, pigment is in the process. It will be added in suitable amount into the water. Mixing is implemented at very high rate in this process which is different from the first phase. In the mixing process, when the particle is small enough, it will be added into the main batch. In the final phase, the resin and other necessary ingredients will be added such as colorants and preservatives.<ref name=":0" />

In the process of checking the quality, specialists will check in the lab for physical and chemical characteristics such as pH determination, viscosity checks, appearance and odor evaluations. In case of mistake such as the ingredients are not enough for making correction fluid, this problem will be solved by adding more ingredients. When this process is finished, the correction fluid will be pumped to a holding tank waiting for filling the correction fluid in the next method.<ref name=":0" />

Firstly, the filling process depends on the different package of each product. The filling line and the filling heads holding play a vital role in this process. The empty bottles will be in the conveyor belt and move continuously waiting for injecting correction fluid in each bottle. Secondly, when the filling process is finished, it comes to the packing process. All the filled bottles will be moved to the capping machine to sort the caps and tighten them. Finally, these bottles will be put into the box for shipping to the sellers and customers.<ref name=":0" />
