To further enhance the processing accuracy and consistency of the finished products of air filters, our company has been continuously promoting technological improvement, comprehensively optimizing and upgrading the key link in the production process of air filters - the precise side cutting process. The improvement of this process marks that the enterprise has entered a new stage in terms of refined manufacturing and quality stability.
Why is the precision side-cutting process so crucial?
After the air filter is folded and formed, it needs to be precisely cut on the side to keep the corrugated structure of the filter paper consistent and ensure a complete match with the frame size. The accuracy of side cutting is directly related to:
Whether the filtration area has been fully utilized
Whether the sealing performance with the shell is reliable
Whether the filter element structure is stable and durable
Whether the product appearance is neat and beautiful
Therefore, a high-level side-cutting process is the core link to ensure the performance and quality of air filters.
The highlights of the upgraded side-cutting precision process of our company
To achieve higher product consistency and stricter precision control, the company has comprehensively upgraded from multiple dimensions such as equipment, processes, and inspection.
The new equipment is equipped with
±0.2mm high-precision cutting control
Multi-blade synchronous cutting technology
High-speed cutting does not burn edges or cause stringing
Automatic deviation correction and voltage stabilization function
Effectively solve common industry problems such as large human errors and uneven cutting surfaces.
Second, adopt a laser positioning system to enhance cutting stability
The upgraded laser positioning system can achieve:
Automatic alignment
The tangent line is precisely linearized
Automatic Angle calibration
Ensure that highly consistent cutting quality can still be maintained during large-scale continuous production.
Iii. The corrugated protection structure has been further optimized
To prevent ripple collapse during the cutting process, our company has added: Before the side cutting process
Special clamping structure
Corrugated protective guide rail
Ensure that the filter element maintains its structural integrity during the cutting process to avoid deformation and indentation.
A perfect post-cutting inspection process
All side-cut filter elements must pass through:
Edge flatness detection
Width dimension verification
Inspection of the integrity of corrugated structures
Assembly trial fitting test
Ensure that the finished product adheres closely to the casing without any loosening, lifting edges or air leakage issues.
The quality improvement brought by precise side cutting
Through technological upgrades, our company's air filters have been further improved in the following aspects:
The consistency of product dimensions is higher
The appearance is flatter and neater
The filtration area is utilized more fully
The sealing performance has been significantly improved
The complaint rate and the return rate have declined
It has been unanimously recognized by many overseas customers, providing a strong quality guarantee for the enterprise to further expand the international market.
