The development of plastic packaging products in my country is relatively late. After more than 20 years of development, the market demand for blow molding products is increasing every year, and the market will be even larger in the future. Today we will introduce what is the hollow molding equipment?
Hollow molding equipment is actually used to produce all kinds of hollow products, such as common warning posts, plastic barrels, roadblocks, septic tanks, kayaks, double-ring barrels, pallets, solar tanks, mobile toilets, floats, and medical beds. Heads and IBC barrels belong to the production range of hollow molding equipment.
The production of hollow molding equipment in my country started late, but the development is very fast. Now and on a large scale, there are also many large-scale hollow molding equipment in China, which can produce from 0.5L to 1000L, and some manufacturers can produce tens of thousands of liters of blow molding products. It also has technical production capacity. In the course of years of development, product types have increased, while the level of automatic control is also improving, of which PLC automatic control accounts for more than 70%.
The output of large-scale hollow molding equipment is low and the variety is small, but there will be various problems in the production process. The wall thickness may not be uniform, thick, thin, and the production efficiency is relatively low. There is still a certain gap with foreign technology. .
At present, the existing domestic hollow product molding methods include: blow molding hollow molding equipment, injection molding machines, plastic film extrusion molding machines, thermoforming rotary molding, compression molding and other production forms. Among the many hollow product molding methods, blow molding and injection molding are one of the two most widely used and most productive molding methods, and most of the plastic containers on the market are blow molded, such as various types of bottles. , Tanks, barrels, storage tanks, etc.
The materials of the hollow products produced by the large-scale hollow molding equipment mainly include polypropylene, polyethylene, and polycarbonate. From these materials, various hollow pallets, clean water buckets, and hollow plastic fuel tanks are produced, which can be used in various industries. In the manufacturing process.
