We should enjoy a good reputation in the industry, and we can increase the added value of the products of cooperative customers through technological innovation.
1. Steel: The main structural material used in blow molding machines is steel, which provides strength and durability to the machine.
2. Aluminum: Some parts of the machine, such as the extruder, may be made from aluminum due to its lightweight and corrosion-resistant properties.
3. Plastic: The molds used in blow molding machines are typically made from plastic, such as high-density polyethylene (HDPE) or polypropylene (PP).
4. Rubber: Rubber is used for seals and gaskets in the machine to prevent leakage and ensure airtightness.
5. Brass: Brass is used for valves and fittings in the machine due to its corrosion resistance and ability to withstand high temperatures.
6. Copper: Copper is used for electrical components and wiring in the machine due to its good conductivity.
7. Stainless steel: Some parts of the machine, such as the heating elements, may be made from stainless steel due to its resistance to corrosion and high temperatures.
8. Glass: Glass is used for the viewing window on the machine, allowing operators to monitor the production process.
9. Ceramic: Ceramic is used for heating elements and insulation in the machine due to its ability to withstand high temperatures.
10. Composites: Some parts of the machine, such as the control panel, may be made from composite materials, which offer a combination of strength, durability, and lightweight properties.

2.What is the working principle of a blow molding machine?

We focus on innovation and continuous improvement to maintain a competitive advantage.
The working principle of a blow molding machine involves the use of compressed air to inflate a molten plastic tube or parison inside a mold cavity. This creates a hollow shape that is then cooled and solidified to form a plastic product.
The process begins with the plastic material, usually in the form of pellets, being fed into a hopper and then melted in an extruder. The molten plastic is then forced into a long tube or parison, which is then clamped between two halves of a mold.
Next, a nozzle is inserted into the parison and compressed air is blown into it, causing the plastic to expand and take the shape of the mold cavity. The mold is cooled to solidify the plastic, and then the mold halves are separated, and the finished product is ejected.
The blow molding process can be either extrusion blow molding or injection blow molding, depending on the type of machine used. In extrusion blow molding, the parison is formed by extruding the molten plastic through a die, while in injection blow molding, the parison is formed by injecting the molten plastic into a mold cavity.
The working principle of a blow molding machine is based on the principles of thermodynamics and fluid mechanics, where the expansion of compressed air inside the parison creates pressure that forces the plastic to take the shape of the mold. This process allows for the production of hollow plastic products with complex shapes and sizes.

3.What kind of bottle is suitable for making with the blow molding machine?

Such as washing supplies, hotel supplies, personal supplies, food, medicine, pesticides, wide-mouth bottles and other PETG and PVC packaging industries, etc., can be produced by the blow molding machine.
