sealed round pail is the prototype of PET bottle molding, then let's take a look at the molding and production process of sealed round pail.

sealed round pail forming

sealed round pail is generally formed by hot runner mold, and it is best to have a heat insulation plate between the mold and the injection molding machine template, whose thickness is about 12mm, and the heat insulation plate must be able to withstand high pressure. The exhaust must be sufficient to avoid local overheating or fragmentation, but the depth of the exhaust port is generally not more than 0.03mm, otherwise it is easy to produce flash.

sealed round pail's production process

The quality of the bottle depends on the quality of the supplied sealed round pail, sealed round pail injection molding is divided into two types, one is a long gate, the other is a short gate. Domestic bottle germ manufacturers choose more short gate bottle germ, while foreign countries choose more long gate. Since the bottom gate of the bottle embryo is cut off, the tension is evenly distributed in the blowing process, so that the quality of the bottle will be better, and the cut part can be recycled, which is conducive to saving raw material costs, in today's increasingly scarce oil resources, domestic manufacturers will be more inclined to long gate bottle embryo. The quality control of the bottle embryo in the production process depends on the degree of control to avoid scratch of the bottle embryo during transportation.

sealed round pail tube wall thick, high transparency, and can be sealed with a general plastic bottle cap, coupled with the advantages of breaking, can stand on the table, you can do a lot of use instead of test tubes.
