Machine Introduction
Automatic Dual-Station 4-Cavity Blow Molding Machine
This equipment is a fully automatic, all-servo-driven, four-head extrusion blow molding machine featuring an 80mm screw and a dual-station alternating operation design. It utilizes a "one-out-of-four" die head configuration and full servo control for all movements, ensuring high automation and high output. It is suitable for the mass production of small-to-medium-sized HDPE and PP plastic containers, such as bottles for daily chemicals, disinfectants, and food products, as well as motor oil jugs.

Key Features
1. Extrusion System:
Features an 80mmspecialized blow molding screw with an optimized L/D ratio, ensuring uniform and stable plasticization.
Multi-zone independent temperature control and air cooling facilitate thorough material melting;
compatible with various raw materials (HDPE, PP), it offers stable extrusion flow and allows for quick color or material
changes.
2. Station Structure:
Dual-station alternating clamping allows the left and right mold carriages to
operate independently without waiting for one another, significantly shortening the cycle time.
Equipped with a four-parison die head (1-out-of-4 configuration),
it produces four bottles simultaneously, substantially boosting production capacity.
3. Drive System (All-Servo):
Servo motors drive all key functions—clamping,
carriage movement, extrusion, and wall thickness control. This ensures precise positioning and rapid response.
Compared to traditional hydraulic models, energy consumption is reduced by 30%–40%;
the absence of hydraulic oil leakage maintains a clean workshop environment and lowers maintenance costs.
4. Control System:
Features a PLC and large touchscreen HMI for fully automated operation.
It supports the storage and recall of multiple product process parameter sets.
Includes programmable wall thickness control for precise adjustment of thickness across the bottle body,
ensuring uniform wall thickness in the finished product; also equipped with fault alarms and safety interlock protection.
5. Automation Functions:
Supports automatic mold opening, blowing, part removal, and flash trimming.
It can integrate with conveyor belts and scrap recycling systems to enable low-manning or unattended production.
Applications
Applications:
This versatile machine is well-suited for manufacturing a wide range of hollow products, including:
