SHOCK ABSORBERS
What the Buffer Does During Operation
During machine operation, the buffer slows down moving parts before they reach a hard stop. This reduces sudden force transfer to the mold frame.
In practical use, this leads to:
More stable mold movement
Less vibration during high-speed cycles
Reduced stress on mechanical connections
The buffer works in the background and does not affect the normal running speed of the machine.
Effect on Machine Condition Over Time
On high-speed rotary machines, impact-related wear often appears first on mold mounting points and surrounding structures. After the buffer is installed, these areas are exposed to lower peak loads.
This helps reduce:
Abnormal noise during mold movement
Wear on joints and contact surfaces
Impact-related damage between maintenance intervals
As a result, machines are able to run more smoothly during long production periods.
Use in Food and Beverage Bottle Production
For food and beverage applications, stable operation is critical. Excessive vibration or shock can affect not only mechanical parts but also hydraulic systems.
By limiting impact and vibration, the buffer helps reduce risks related to food-grade hydraulic oil systems, such as leakage or contamination caused by mechanical stress. It also supports more consistent mold stretching and mold opening behavior on high-speed lines.
Materials and Internal Structure
The buffer is produced using industrial-grade materials selected for durability under repeated load cycles. Its internal structure is designed to handle continuous motion rather than occasional impact.
This makes it suitable for rotary blow molding machines that operate for long hours with short cycle times.
Available Types and Installation Options
Different buffer models are available for various installation positions. Thread size and mounting details can be adjusted according to customer requirements.
This allows the buffer to be installed on different mold frame designs and machine configurations without major changes to existing equipment.
Where the Buffer Is Commonly Used
Rotary blow molding machines
Mold opening and closing mechanisms
Stretching cylinder systems
PET bottle production equipment
The buffer is used in positions where movement needs to stop smoothly instead of abruptly.
Basic Working Concept
When a moving part reaches the end of its travel, the buffer absorbs kinetic energy and slows the movement in a controlled way. This avoids a direct hard stop and reduces the load transferred to the machine structure.
Over time, this contributes to more stable operation and longer service life of mechanical components.
