Blow molding machine is a kind of equipment that makes plastic particles into hollow containers through a blow molding process. Currently, there are two common types. One is a single hollow extrusion blower using PP and PE, and the other is using PET. , PC or PP secondary injection injection stretch blow molding two-step bottle blowing machine. The two-step bottle blowing machine is widely used in any shape of carbonated beverage bottles, mineral water bottles, cosmetic bottles, edible oil bottles, pesticide bottles, large-caliber bottles, high-temperature bottles and other packaging containers with crystalline plastics, such as PET and PP For raw materials. Many novices in the plastic bottle industry need to understand and learn a lot of knowledge before buying, and they need to buy according to their own needs. The more expensive the blow molding machine, the better it is, but it may not be right for you. Since there are many types of blow molding machines, they are usually divided into semi-automatic blow molding machines, manual insertion automatic blow molding machines and automatic blow molding machines. Taihui Machinery Co., Ltd. can be customized according to customers' different output and bottling volume.
Now briefly introduce the two steps of the next two-step blow molding machine in production
1. Warm up
The preform is irradiated with an infrared high temperature lamp, and the preform is heated and softened. In order to maintain the shape of the preform, there is no need to heat the preform mouth, so a specific cooling device is required to cool it.
2. Blow molding
At this stage, the pre-heated preform is put into the finished blow mold, the stretching rod is stretched downward for high-pressure inflation, and then the preform is blown into the desired bottle shape.
Features of semi-automatic bottle blowing machine:
1. Blow 0.1-5 liter PET bottle (choose one of the two), 5L-20L (single cavity)
2. Using two cavity molds to blow 500ml bottles, the output can reach 2000 per hour
3. Advanced PLC control system, time control can be accurate to 0.01 second
4. Dedicated gas storage device
5. Using infrared tube heating, strong penetrating power, revolving heating of the preform, orbital revolution, uniform heating, fast and reliable
6. Different heating lamps are equipped with independent temperature control devices to ensure the ideal heating effect of the preform
7. The direction of the heating lamp can be adjusted according to different preforms
8. Only one person can operate, no special training is required
9. Simple installation and startup
10. The scrap rate of finished products is less than 0.1%
