Injection Stretch Blow Molding Machine ISB800
This machine has three stations, injection preform, blowing & stretch and product release. The raw material comes from the hopper to the injection screw to inject preform; the plate rotates preforms to blow/stretch blow station with themselves heat, without any reheating for blowing,then the product will rotate to release station and drop down, It's fully automatically cycle rotation working mode,no need to buy bottle preform, no waste, high degree of automation, finished products smooth and beautiful.
Commonly used in 10-1000 ml PET cosmetic bottle, milk bottle, sports water bottle, pharmaceutical packaging, PC bottle, red wine cup and LED lampshade, etc

1. The wheel rotation is driven by electrical servo motor, not hydraulic.
2. Full automatic controlling system, easy operating.
3. The temperature of material barrel and hot runner is controlled accurately by PIT.
4. More cost is saved than traditional machine.
5. Compact structure; less space needed.
6. Injection: Hot runner and temperature control device are standard configuration. Only change mold for making a new product;
Stretch Blow: Hydraulic mold clamping, core insert, stretch blow and bottom molding are standard configuration;
Product Release: Equipped with a standard ejector.
With the increasing requirement of high quality and elegant appearance in the packing field of food, beverage, and cosmetic, the plastic containers made by the old style extrusion blowing machine cannot meet the customer’s demand any more. However, by one step injection stretch blow molding machine, from the raw material to product processed are all by one step.The whole process includes preform injection,stretch blow and release. No need trimmings, No runner gate material ( no scrap ), but perfect neck, bottom and line, higher transparent, higher rigid. Stretch-blowing molding products come with thinner wall and save more material. PET water bottle stretch blow molding machine completes a high speed molding without preform reheated. With the heat from preform injection to stretch and blow, unnecessary reheating and shorten preform cooling time to save energy. Injection Stretch blow molding machine optimizes the working structure, removes molding disadvantage factor, cuts off the complicated working procedure to ensure molding more reliable and increase the reject rate. One Step Injection Stretch blow moulding machine decrease the convey cost and avoid the second contamination, special for food and pharmaceutical company. For example, to transit the 19g 500ml bottle, if the 1m³ trunk used, it can load 1024 bottles, or 9280 preform, but if buy the raw material that can produce 56421 bottles. The logistic cost of material comparing with transiting bottles can be reduced by 98.2%; Comparing with the cost of transiting preform, the cost can be reduced by 83.6%.

Molding | Process | Structure | | Product Quality |
Dawson One-step Injection Stretch Blow Molding Machine | From preform to product in one machine | One machine | Little | Not affect by damp and less pollution; Various kinds of shape |
Other machine | Injection and blow molding are two separated process | 1.Injection molding machine 2.Preform transiting machine 3.Reheating, stretch and off-moulding machine | More | Easy affect by damp and polluted; Singleness shape |
