AVI Visual Inspection Machine for Sheet Materials
Background of the Panel Industry: From Manual Inspection to AVI Quality Control
Wood flooring is a consumer product used in home decoration and renovation. It is primarily divided into five major categories: laminate flooring, engineered wood flooring, solid wood flooring, bamboo flooring, and cork flooring, with the first three being the mainstream products.
Currently, manual inspection is the most common method used for detecting and classifying surface defects on sheet materials. However, the overall accuracy rate of manual inspection is less than 75%, making it difficult to meet the needs of companies with high quality standards. As a result, an increasing number of companies are adopting AVI inspection equipment to reduce costs and improve efficiency.
Manual Inspection
1. High labor costs
2.High error rate/low efficiency
3.Difficulty in standardizing procedures
4.Inability to trace data
AVI Quality Inspection
1.Reduce Overall Costs
2.Reduce customer complaints and enhance brand image
3.Real-time inspection, compatible with a variety of textures and materials
4.High inspection accuracy, helps improve manufacturing processes, and increases production yield
