Machine Introduction
70 Screw Double Station 2-Cavity Electric Semi-Hydraulic Fully Automatic Blow Molding Machine
This model is a high-efficiency and stable fully automatic extrusion blow molding machine specially optimized for small-capacity HDPE plastic containers. Equipped with a 70mm high-precision plasticizing screw, it delivers uniform plastic melting, stable extrusion volume, and excellent material compatibility for HDPE and PP raw materials.
Adopting double-station and 2-cavity design, the machine greatly improves production efficiency compared with single-station equipment, realizing continuous and mass production of small bottles. The electric semi-hydraulic control system balances fast running speed and stable mold clamping pressure, effectively reducing machine vibration, lowering failure rate, and ensuring consistent bottle wall thickness and finished product stability.

Key Features
1. High Production Capacity
Adopts double-station and double-cavity alternating working structure. The production efficiency is nearly doubled compared with single-station machines, supporting stable and mass production of 0.1L to 1L small plastic bottles.
2. Excellent Plasticizing Performance
Equipped with a 70mm high-precision extrusion screw. It provides uniform plastic melting, stable discharging speed and consistent parison thickness. Perfect for processing HDPE and PP raw materials with smooth bottle surface and no obvious weld lines.
3. Electric Semi-hydraulic System
Adopts electric-assisted and semi-hydraulic driving design. It features fast running speed, balanced clamping force, low vibration and high stability. Effectively reduces machine failure rate and ensures long-term continuous operation.
4. Wide Production Compatibility
Capable of producing various small-capacity hollow containers, including round bottles, square bottles, flat bottles, irregular shaped bottles, small handle bottles, daily chemical bottles and pharmaceutical bottles. Mold replacement is simple and flexible.
5. Full Automatic Operation
Realizes automatic mold clamping, automatic blowing, automatic deflating and automatic product discharging. Only one worker is required for supervision, greatly saving labor costs and improving production automation level.
6. High Molding Precision
The machine body adopts rigid structural design with precise mold positioning. The finished bottles are full-shaped, burr-free and deformation-free, maintaining a high qualified rate.
7. Energy Saving and Cost Effective
Optimized specially for small bottle mass production. It consumes lower energy, runs stably and requires simple daily maintenance. It is an ideal cost-effective equipment for small and medium packaging factories.
