Product type
Blow molding machines are specialized equipment used for manufacturing hollow plastic parts by inflating heated plastic within a mold. They typically consist of an extruder, a mold, and a blowing mechanism. The process involves melting plastic resin, forming it into a parison, and then inflating it to take the shape of the mold. These machines are commonly made from high-strength steel and incorporate advanced control systems for precision and efficiency.
| Machine type | Extrusion blow molding or injection blow molding |
| Mold capacity | Typically ranges from 1 to 100 liters |
| Production speed | Up to 1200 bottles per hour |
| Power supply | Electric or hydraulic |
| Control system | PLC or computer-based control |
When selecting a blow molding machine, consider the type of molding process that best suits your production needs, such as extrusion or injection. Specify the desired mold capacity and production speed based on your output requirements. Additionally, inquire about the machine's power supply options and control systems for better automation. Certifications and tolerances may also be important depending on the industry standards you need to meet.
