What kinds of heads are used for hollow blow molding machines? In what situations does each apply? There are three kinds of heads used for blow molding, one is a common pipe head, one is a material storage cylinder head, and the other is a parison adjusting head. These three heads are respectively used in the following three situations. Below I will give you a brief introduction. The types and applications of three common hollow blow molding heads: 1. Ordinary…

What are the commonly used blow molding methods? The hollow blow molding process is divided into extrusion blow molding, injection blow molding, stretch blow molding, and stretch blow molding has two kinds of blow molding processes: extrusion stretch blow molding and injection stretch blow molding. What are the characteristics of blow molding? This article will give you a detailed summary. 1. Blow Molding Methods-extrusion blow molding It is suitable for various types of plastics, with high production efficiency, uniform parison…

There are several options for the material of the blow molding machine mold: iron and steel, aluminum and aluminum alloy, beryllium copper alloy, and high-grade zinc alloy. The following is a detailed introduction to the hollow blow molding machine molds of these four materials, which are suitable for each situation. 1. Iron + steel blow molding machine mold Steel material not only supports the frame and structure of the hollow blow molding machine but also can be used as the…

The hollow blow molding machine is one of the main pieces of equipment in the hollow blow molding industry. This article will discuss with you the development status of hollow blow molding machine technology in recent years.   The hollow blow molding machine has gradually become a hollow blow molding machine production line. The advent and continuous development of these intelligent production lines of hollow blow molding machines have greatly reduced the number of operators on the production site, and…

Today, let’s talk about the reasons and solutions for flow marks on blow molding machine products. The processing speed of blow molding products is fast, and the processing speed of ceramic wood products containers is relatively slow, which is time-consuming and labor-intensive and cannot reach the required accuracy. Moreover, plastic containers are cheap, which can effectively reduce the cost of living. However, during the blow molding process, flow marks and jet lines are often found in blow molding machine products.…

Inadequate sealing or air leakage of the storage blow molding machine is caused by many reasons. Today, let’s talk about the reasons and solutions for the inadequate sealing of the storage blow molding machine. One is the insufficient pressure of the sealing cylinder. If a low-pressure sealed cylinder is selected, the low-pressure pressure can be kept below 8 kg, and the general product is no problem. But it also depends on the high-pressure blowing pressure. If the high-pressure blowing pressure…

Today, let’s talk about the reasons and solutions for the soft bottom of the hollow blow molding machine. The wall thickness of plastic blow molded products is one of the important factors affecting product quality. If we want to produce high-quality plastic blow-molded products, the wall thickness control of plastic blow-molded products cannot be ignored. Let me share with you the reasons and solutions for the soft bottom of the hollow blow molding machine. 1. Adjust the gap of the…

Today, let’s talk about the precautions for the pressure gauge detection of blow molding machines. The blow molding machine pressure gauge is an important pressure reference instrument. Before installation, it needs to be inspected by the relevant national measurement units, and the relevant inspection qualification certificate will be presented after the inspection is qualified. To ensure the qualification and accuracy of the pressure gauge, it can be determined according to the frequency of use. Generally, the measurement verification of the…

The blow-molded floating pontoon is made of ultra-high-density polyethylene resin as raw material and produced by a blow molding process. Today, let’s talk about the advantages and disadvantages of a blow-molded floating pontoon. A blow-molded floating pontoon has the characteristics of lightweight, high buoyancy, strong resistance, strong impact resistance, long service life, and strong durability. The floating bridge has no gaps, no water seepage, one-time forming, anti-freezing, anti-ultraviolet, alkali resistance, environmental protection, and pollution-free. Quick installation, flexible assembly, anti-skid technology…
