What should be paid attention to in the acceptance of new equipment of blow molding machine? Whether the new equipment of the blow molding machine is installed in place is very important to the future use effect. Our newly purchased blow molding machine should be installed as far as possible on a concrete floor with good ventilation and sufficient light. The environment around the equipment should be open to facilitate the operation and maintenance of the equipment. It is generally…

Today, let’s talk about how to shut down a large blow molding machine during a power outage or abnormal accident during normal production. Hollow blow molding is a method of inflating a hot melt parison closed in a mold to form a hollow product by means of gas pressure. It is one of the most commonly used plastic processing methods, and it is also a rapidly developing plastic molding method. The mold used for blow molding is only a female…

Today, let’s analyze the reasons and solutions for the plastic barrel blow molding machine’s scissors not cutting. When the plastic barrel blow molding machine does not cut the scissors, we must first consider the material supply and eliminate it step by step from the process flow. The first reason is that the cutting installation is unreasonable, the cutting edge of the scissors is not sharp enough, the scissors handle is larger, and the scissors spray too much water to reduce…

Today I recommend everyone to watch a video of the production and operation of a hollow blow molding machine. The video shows the entire process of Yankang’s 1000L-6 layer plastic barrel large blow molding machine in production. This blow molding machine can produce multi-layer plastic barrels of different models and specifications, ranging from 200L to 1000L, with 1-6 layers.  In addition to blowing plastic barrels, this equipment can also support other product customization, such as customized transportation facilities, roadblocks,…

The reason why the extrusion material of the blow molding machine is long and short is the main content of this post. There are many reasons for the extrusion material of the blow molding machine to be longer and shorter. The most important point is the control of the temperature. It can be divided into the following types: no-flow temperature, flow temperature, decomposition temperature, melting temperature, and glass transition temperature. It is very important in the extrusion blow molding production…

The reason and solution for the abnormal discharge of the blow molding machine screw is the subject of this post. The phenomenon that the screw of the blow molding machine is abnormally discharged is mainly caused by the excessive clearance of the screw and barrel of the extruder. We all know that the screw and barrel gap is too large, the flow of the extruded material is unstable, and the surface of the blown product is prone to horizontal wrinkles.…

Today, let’s talk about how to change the filter screen of a hollow extrusion blow molding machine. Let’s take a look at the impact of the hollow extrusion blow molding machine filter on plastic extrusion molding. In the production process of the plastic blow molding machine, the plastic raw material is transported to the die through the filter. The material can be filtered and the mixing effect of the material can be improved. It is worth noting that the filter…

Today, I will talk to you about what raw materials are used for blow molding of hollow blow-molded trays? How is its performance? The production of hollow blow-molded trays is mainly made of high-density polyethylene HDPE as the main raw material. A certain proportion of secondary recycled materials can be added according to customer requirements, and appropriate fillers and masterbatch can be added according to the different uses of the product. Most of the HDPE used in the production of…

Whether the plastic road barrier is better for blow molding or rotomolding has always been an issue of constant debate in the plastic products industry. The plastic road barrier is also called isolation barriers. Commonly used are cement barriers, fiberglass barriers, and plastic road barrier. Isolation barriers are mainly used for transportation facilities and play a protective role. The main thing to be discussed today is plastic road barrier. The plastic road barrier of the blow molding process can make…

Today, let’s talk about the causes and solutions for the unsmooth surface of blow-molded products. Do customers often ask why the products blown by the blow molding machine are not smooth, like sharkskin? So why does this strange shark skin phenomenon occur? The following editor will analyze the causes and solutions of this phenomenon from several aspects. To find out the reasons and solutions for the unsmooth surface of blow-molded products, we must first understand the blow molding process: hopper…
