The tool box mold is mainly used for batch production of tool boxes and has the following important uses:
1. ensure product accuracy: the tool box mold can ensure that each tool box produced is highly consistent in size and shape with high accuracy. For example, the dimensional accuracy of the mold cavity can be controlled within ± 0.01mm, so that all parts of the tool box can be matched correctly. For example, the cover and the box can fit closely, without too large or too small gap, so as to ensure the overall quality and performance of the tool box.
2. improve production efficiency: the molding production through the mold can realize the one-time molding of multiple parts or the toolbox with complex structure, which greatly reduces the processing process and assembly time of single parts. Compared with manual production or other non mold forming methods, the production efficiency can be improved several times or even dozens of times, which can meet the needs of large-scale production.
3. reduce production cost: Although the initial investment cost of the mold is high, the mold cost allocated to each toolbox will gradually decrease in mass production. Moreover, mold production reduces material waste and labor costs, while improving production efficiency, which can effectively reduce production costs.
4. realize complex structure design: Modern toolbox often has complex structure and appearance design, such as stiffener, concave convex shape, various mounting holes and slots, etc. The tool box mold can correctly shape these complex structures according to the design requirements, so that the tool box not only has practical functions, but also has good appearance and humanized design.
5. ensure the stability of product quality: the mold production process is relatively stable. As long as the mold is properly maintained, the toolbox products with stable quality can be continuously produced. It will not be affected by human factors and environmental factors like manual production or other unstable production methods, resulting in fluctuations in product quality.
