AI Technical Summary
In existing technologies, the color area size of two-color plastic containers is easily affected by changes in equipment operating time, plastic melt quality, and ambient temperature, making it difficult for molding equipment to maintain high precision. Increasing the frequency of inspection can only reduce the number of defective products, but cannot completely solve the problem.
By setting a secondary flow channel in the extrusion blow molding equipment, the temperature, pressure and extrusion volume can be adjusted in real time. The secondary flow channel's second temperature, second pressure and second extrusion volume can be automatically adjusted according to the actual size deviating from the preset range, ensuring that the actual size gradually returns to the preset range and avoiding the generation of defective products.
It enables automatic adjustment of production parameters under the influence of external factors, ensuring that the actual size of the two-color plastic containers remains within the preset range, reducing the generation of defective products, and improving production stability and accuracy.
