Now most of the industrial industry is already automated production management mode, you think that 1l sealed round pail only need to put the PET bottle on the machine can shape itself, that is wrong! In fact, some process details will affect the quality of 1l sealed round pail, so what should we pay attention to in production?

1l sealed round pail processes and methods in the production process: including extrusion, injection molding, blow molding, calendering, laminating, casting and other ways. 1l sealed round pail Transfer, blow molding, plastic heat melt, then press into a special blow molding mold and internal air pressure, pressure, molding plastic, The shape of the final product is formed because of the external pressure of the bottle shape time, so the focus is on the bottle itself, when the heating temperature reaches a certain degree, the plastic will be softened, the pressure resistance is small, so the bottle will become smaller and smaller. In certain processing characteristics and production of 1l sealed round pail, according to a certain grace period treatment means, and to ensure the quality of production and processing and good performance of the use. Here are some of the processing characteristics of 1l sealed round pail in different aspects:

First: The high shrinkage rate enhances the shrinkage of small plastics than the general pressure, which is mainly through the shrinkage of the thermal shrinkage of the composition and chemical structure. The first factor that affects the variety of shrink plastics. Compared to ordinary epoxy phenolic resin, epoxy phenolic resin, unsaturated polyester, etc., a minimal shrinkage unsaturated polyester material influences factors such as the shape and thickness of shrinkable plastic parts, large thick walls such as plastic and glass fiber filling contain a small volume shrinkage, the volatile content is also very suitable for large shrinkage, forming pressure, volume shrinkage, than cold load heat shrinkage, lack of large Type of curing shrinkage stripping. Will affect the use of plastic bottles, in order to reduce and prevent the use of shrinkage is an important phenomenon is one of the important factors of shrinkage, affecting the actual use effect.

Second: strong mobility of plastic bottles than the general pressure, enhance the plastic material of the liquid resin is easy to produce excessive accumulation and glass loss respectively. The formation pressure and temperature will increase significantly, and the fluidity is affected by many factors, and the evaluation of the fluidity of certain materials must be analyzed specifically, which is the factor that affects the fluidity.

Well, this is the basic precautions of the 1l sealed round pail production process, there are still many small details to pay attention to in the production process, which requires you to constantly sum up experience in the production process!
