Hollow blow molding machine

▶ Hollow blow molding machine

It mainly consists of extruder, head, hydraulic system, clamping system, electrical control system, inflation system, automatic chuck, etc. The basic framework is mainly composed of two main structures: power part and heating part. The power part mainly consists of a frequency converter and a power output motor, which are the main working components for energy transmission and wind power output. The heating part is composed of an electromagnetic heater and a bracket, which can be used to heat plastic that needs to be wind molded, maintaining the characteristics of long-term softening.

▶ Process flow of hollow blow molding machine principle

Quantitative automatic feeding - Plasticizing raw materials - Heating and insulation of the machine barrel mold head - Starting extrusion - Forming a molten plastic mold - Entering the mold - Closing - Blowing needle up - Cutting knife cutting off excess mold - Mold head up - Mold base moving right - Blowing needle down - Blowing air cooling forming - Blowing needle micro extraction - Pulling down - Mold opening - Product removal - Automatic cycle.

If it is a fully automatic extrusion hollow blow molding machine equipment, the entire production process from material loading to product completion can be automated, and only 2-3 people are needed on the production site.

▶ Classification of hollow blow molding machines

Hollow blow molding machines can be divided into continuous extrusion hollow blow molding machines and intermittent extrusion hollow blow molding machines based on their extrusion methods.
