Detail Basics About Hengxin The Blow Moulding
Injection blow molding is widely referred to as a manufacturing process. This process combines the precision of injection molding with minimal waste and rapid Blow Moulding. It can work with plastic. It specializes in creating divine shapes such as bottles. Because blow molding methods are less expensive than manufacturing methods, these methods are commonly used to make larger containers by using extrusion blow molding. The output of this technique is usually not clear glass seams.
The blow mould process involves three stages, including injecting material into a preform mold, blow molding, and final product discharge from the machine. The commonly used machine configuration is a blow molding machine with these stages. The machine can rotate 120 inches at each stage of the molding process.
The injection phase begins when molten glass or plastic is injected into the preform mold on the mandrel. It can form the interior of the parison, you can also complete the neck. Then, the parison is separated from the mold and then inserted into the blow mold. In the blow mould, the parison will be pressurized air to inflate. Then, after cooling, the product will be discharged from the machine. The final step is to test whether the product leaks and then move it to another station for collation or labeling.
When designing a model of the product you are about to make, you have to think about some important issues. You must consider choosing the right thermoplastic resin for your application, designing the geometry of the mold, shrinking the material during the cooling phase, and calculating the amount of material to be injected. Another important factor you have to consider is choosing the right pressure to inflate the parison. At design time, the tolerances of the mandrel and the preform mold must be taken into account so that core erosion can be perfectly placed on the center of the mold and the parison can have a constant wall thickness. There are many products that can be made by blow mould, especially bottles, cans, and small containers.
