December 31, 2024 – Chengdu Kalefu Polymer Materials Unveils Innovative Masterbatch Screening Device with Enhanced Protection
Chengdu Kalefu Polymer Materials Co., Ltd. has made significant strides in the field of plastic masterbatch processing technology, recently securing a utility patent for an “Enhanced Protection Masterbatch Screening Device.” The patent, bearing the authorization announcement number CN 222201261 U, was formally submitted in May 2024.

The patent abstract introduces a groundbreaking masterbatch screening device, with the core focus on the design of the screening box. At the heart of the box lies an efficient screening mechanism, comprising three major components: the screening assembly, collection frame, and drive component. The screening assembly, which includes a screening frame and mesh plate, is responsible for the precise screening of plastic masterbatch. The collection frame, strategically positioned beneath the screening frame, collects the screened masterbatch. Notably, the inner sides of the symmetrically arranged clamping side plates at the bottom of the collection frame are equipped with magnetic blocks, which connect to one side of the drive component. The other side of the drive component is securely attached to the rear lower end of the screening frame via a support frame, ensuring stable operation of the entire screening mechanism.
According to the Color Masterbatch Industry Network, another highlight of this screening device is its exceptional protection design. The device is equipped with guiding elements to ensure that the plastic masterbatch accurately lands on the screening mesh plate during the feeding process. Additionally, protective frames are installed on both sides of the screening mesh plate to prevent masterbatch from falling off during screening. Furthermore, the device thoughtfully includes splash guards that work in tandem with the guiding elements to provide precise direction for the fed masterbatch, significantly enhancing the device’s operational safety.
The acquisition of this new patent not only showcases Chengdu Kalefu Polymer Materials’ profound expertise in the field of plastic masterbatch processing technology but also lays a solid foundation for its future development.
