AI Technical Summary

Technical Problem

Existing brake pad hot pressing molding machines suffer from uneven heating of brake pad raw materials during the heating process, resulting in inconsistent curing of the binder, affecting the uniformity of the internal structure of the brake pad, and increasing the defect rate.

Method used

The system employs a dual heating assembly, including a coordinated design of an electric telescopic rod and electric heating columns, to ensure comprehensive and uniform heating within the brake pad molding cavity. The staggered arrangement of the electric heating columns and the avoidance hole design prevent them from touching each other. Combined with hydraulic cylinders and pressure sensors, it achieves precise mold closing and demolding.

Benefits of technology

This technology enables comprehensive and uniform heating of brake pad raw materials, reduces product quality defects caused by uneven local temperatures, and improves the hot pressing molding quality and production quality of brake pads.
