How to demonstrate the impact resistance of plastic toolboxes

The impact resistance of plastic toolboxes is mainly reflected through structural design, material properties, and practical performance. The core is to withstand external impact without breaking or deforming, and to protect the internal tools. 1.

       The impact resistance of plastic toolboxes is mainly reflected through structural design, material properties, and practical performance. The core is to withstand external impact without breaking or deforming, and to protect the internal tools.
1. Core embodiment dimensions
       The impact resistance of the material itself: Mainstream engineering plastics such as ABS, PP, HDPE, etc. are used, which have strong toughness and high impact strength. Some materials also add impact modifiers to enhance their resistance to brittle cracking in low-temperature environments.
       Structural design reinforcement: The box adopts thickened side walls and rounded transition design to avoid sharp angle stress concentration; Some products have built-in reinforcing ribs or honeycomb structures to disperse impact energy; The connection between the box cover and the box body is made of high-strength hinges and buckles, which are not easily detached during impact.
       Performance in actual use: During the drop test (such as dropping from a height of 1-2 meters to a cement floor), the box has no cracks or fractures; When subjected to collision or compression, only minor scratches may occur, which does not affect the closure and protective functions; Long term outdoor or complex environmental use, the impact resistance is not easily degraded.
2. Key influencing factors
       Plastic thickness: The more uniform and sufficient the wall thickness of the box, the stronger its impact resistance.
       Processing technology: Products formed by injection molding have a denser structure and better impact resistance than those formed by splicing.
       Environmental temperature: Excellent products can maintain stable impact resistance and avoid low-temperature brittleness within a wide temperature range of -20 ℃~60 ℃.
