Advantages: The device is relatively simple, less investment. Relatively smooth finish, a good seal. Faster product development, lower tooling costs, the cost price, low.
Disadvantages: injection tube and blow molding step by step, easy transfer of pollution, the seizure difficult to guarantee the identity of the product is poor, do not adapt to mass production.
(3) one-step "Note - blowing" One step injection-Blow moulding. "Injection blow molding" done on the same machine. According to the different models divided into the three-position and two-position "Note - blowing." Three-position "Note - blowing" bottle machine three stations to 120 ° angle of an equilateral triangular distribution, the first station for the injection molding station, a second station for the blow molding station, the third station a bottle off the station. Three stations can be run at the same time, high production efficiency, short cycle, and can be connected to the conveyor belt automatic counting packaging, pharmaceutical plastic bottle production to realize the whole process and manpower "non-contact" to ensure clean and hygienic products. Two-position "Note - blowing" plastic machine two stations can be up, down or in tandem; a first station for the injection molding station, a second station for the blow molding stations; due to the small bottle and a dedicated cooling off station, so difficult to achieve automatic counting packaging (typically bulk manual counting). In addition, longer production cycle, production efficiency is lower than three-station.
Advantages: High degree of automation, high production capacity. Bottle flatness, excellent seal. Choose HDPE / PP raw materials, sidewall evenly, excellent barrier properties, charging shelf long period of storage. At present, domestic enterprises standardized kits are basically one-step "Note blowing" technology equipment, including the "three-position" the main structure.
Cons: large investment in equipment, tooling complexity, system configuration higher requirements. Do not adapt to the small variety, small batch production.
