Product Details

HS series machine is our high level series extrusion blow molding machines. Equipped with hydraulic servo system.
Save energy and with more stable running. The clamping unit adopts elbow style so that with higher and uniform clamping force. Using proportional valve control the mold open & close, and linear guide rail, the movement for the mold open & close will be more stable and fast.
This machine is suitable for producing HDPE/PP jerry cans size below 12liters.
It can be also equipped with multi head die-heads to make small bottles with higher output.
The main parts of this machine are designed and manufactured by ourself. We do the independent R&D and inspection. If you have other special requirements, we can provide customized services for you.

. Each component before assembly needs strictly control by inspecting personnel.
. Each assembly is in charged by a master who has working experience for more than 10 years.
. After all the equipment are completed, we will connect all the machines and run the full production line for at least 12 hours to ensure the stable running in customers’ factory
1) Correct the abnormal shape of the die properly;
2) The product is not cooled enough, and the cooling water temperature needs to be lowered, or the cycle should be appropriately extended;
Need to provide the specific information of the old mold, our engineers help confirm whether it can be directly installed on our machine.
We can make oblique products, but we need to look at the angle for details, so please send product pictures to confirm.
Normally small continuous die head extrusion blow molding machines all has single station and double station , the difference is output , single station machine exist more round and back mold moving time.
