In the production of blow molded bottles with 16l sealed round pail wholesale raw materials often encounter the following problems, so today Xiaobian will explain to you the situation that is easy to appear in the production process and the solution.

First, the situation of thick under thin, to solve: need to delay the pre-blowing time, or reduce the pre-blowing pressure, reduce the gas flow.

Second, the situation of thick on the bottom, the solution: the opposite of the solution to the problem.

Third, there will be wrinkles under the bottleneck, to solve: pre-blowing too late or pre-blowing pressure is too low, or the billet cooling is not good here.

Fourth, the bottom of the white, the solution: the main reason is that the bottle is too cold; And at the same time overstretch; Pre-blowing time is too early or pre-blowing pressure is too high.

Fifth, there is a magnifying glass phenomenon at the bottom of the bottle, too much material at the bottom of the bottle, to solve: pre-blowing too late, pre-blowing pressure is too low.

Six, the bottom of the bottle inside the wrinkle, the bottom temperature is too high (the gate cooling is not good), the solution: too late pre-blowing pressure is too low, the flow is too small.

Seven, the whole bottle looks cloudy and less transparent, solve: cooling is not enough.

Eight, local white: excessive stretching, solution: the temperature here is too low, or pre-blown too early, or touch the tensile rod.

The eccentricity of the bottom of the bottle may be related to the temperature of the bottle, stretching, pre-blowing, high pressure blowing, etc. Solution: First of all to reduce the temperature of the bottle; At the same time to speed up the drawing speed; Check the gap between the rod head and the bottom die; Delay the pre-blowing and reduce the pre-blowing pressure; Delay high pressure blowing; After processing, check whether the preform will still appear eccentric.

The above is about 16l sealed round pail wholesale blow molding bottle prone to problems and solutions to explain, read everyone know, I hope to help you.
