Analysis of Vertical vs. Horizontal Electric Wall Thickness
Many customers who do hollow blow molding may encounter a problem when choosing an electric wall thickness control system:
What is the difference between vertical electric wall thickness and horizontal electric wall thickness? Why are the equipment structures different when both have electric wall thickness? In fact, the core purpose of both is the same - to achieve dynamic adjustment of the billet wall thickness through precise control of the die gap. The real difference lies more in the structural layout and transmission mode of the actuator, as well as the matching method with the machine head and the entire machine.
Why are they divided into vertical and horizontal types when they are all electric wall thickness?
PART01Vertical electric wall thickness
Vertical electric wall thickness, the overall layout of the actuator adopts a skewed vertical direction, integrated with the head structure.
Through servo drive, the position of the core rod or related adjustment components is changed to achieve precise clearance between the mold mouth. Its characteristics are mainly reflected in:
01Intuitive layout of execution mechanism
The matching relationship between the direction of motion and the head structure is relatively clear, which facilitates the overall structural design.
02Easy to integrate with the machine head
Targeted design of wall thickness actuators can be carried out based on the head structure and overall equipment layout.
03Suitable for devices of different specifications
Especially in large hollow blow molding equipment, factors such as head size and equipment height can affect the layout of the wall thickness control mechanism, so it is necessary to comprehensively consider the overall structure.
PART02Horizontal electric wall thickness
The horizontal electric wall thickness adopts a layout of actuators that are inclined towards the horizontal direction.
servo motorAfter outputting the motion, it is transmitted to the head adjustment component through the corresponding transmission mechanism to achieve dynamic control of the die gap.
Its characteristics are more reflected in:
01Flexible spatial layout
Combining the overall structure and horizontal layout can better utilize equipment space.
02compact structure
For some equipment structures, a horizontal layout can better utilize equipment space.
03Convenient for different models
Different structural design schemes can be adopted based on the head structure, equipment space, and product requirements.
Vertical vs horizontal, who is better?
In fact, there is no absolute 'who is better'.
Vertical and horizontal are essentially two different structural layout schemes.
What truly affects the effectiveness of wall thickness control is not just whether it is "vertical" or "horizontal", but also includes:
Product structure - Raw material characteristics - Wall thickness requirements - Head structure - Wall thickness actuator - Control system - Actual production pace
Only when each link is matched with each other can a wall thickness control scheme truly suitable for production needs be formed.
