You need one injection molding machine only, with replacing different molds only to produce normal injection molding production, but also can make injection blow molding products like lots of bottles and plastic drums with different shapes in different materials PP, PE, PS, ABS, BAREX, PC, PVC, etc. Our injection blow molding system has very strong adaptability and a very high machine utilization rate, helping you expand the production line and bring down the manufacturing cost.
Why We Developed Horizontal Injection Blow Molding System
Our research found that there are 4 ways to produce bottles.
1. Produced by an extrusion blow molding machine
2. Two-step method: Made preform with an injection machine and then blow to bottle on a blow molding machine.
3. Vertical injection blow machines with the rotary platen and 3 WORKING STATIONS
4. Vertical injection blow machines with the rotary platen and 4 WORKING STATIONS
Both above solutions need additional blow molding machine or a new kind of extrusion blow molding machine for a traditional injection molding factory. But it causes big investment and high risk to expand their production line.
WE then picked this important piece and worked with engineers and developed new series of one step injection blow molding machines to fill the gap. To develop horizontal injection blowing molding machines with high output capacity, high quality but low manufacturing cost & very low investment & low risk. Helping our customer expand their market very quickly and gain great profits.
Now Guanxin Plastic Machinery offers a series of special plastic injection blowing molding machines with extremely competitive prices to help traditional injection molding manufacturers break into a new market.
What Is Horizontal Injection Blow Moulding System
A NEW PATENTED horizontal injection blowIing molding machine running with injection blow molding mold.
A NEW PATENTED mold combined with injection and blowing molding function into ONE mold.
High repeatability precision.
High speed and efficiency, energy-saving and stable, easy for operation and maintenance.
The hydraulic, pneumatic, and electrical controller is adjustable.
Suitable for most thermoplastic plastic, like PE, PP, PS, PC, etc.
The best solution for bottles used in the medical and food packing industry, and high appearance industry like LED lights diffuser, cosmetic bottles, etc.
How These One Step Injection Blowing Molding Machine Works
The preform is a precise shape, with precise wall thicknesses. After the one step injection molding machine open the clamp, then the blow mold cavity will be closed from two sides.
Compressed air is then injected into the center of the part, forcing the unsupported walls of the preform tube to stretch and expand outward, until they hit the walls of the blow mold. Once the material cools and solidifies, the mold is opened and the part is removed.
Injection blow molding allows for the production of hollow parts with some areas of the parts being very precise. Our one step injection blowing molding system can be running with high speed and output capacity. Like running 28 cavity injection blow mold with cycle time about 25 seconds. The output capacity is about 4000 pcs per hour.
Applications for injection blow molding include plastic bottles and plastic packaging with screw top lids.
