Case

A real-world case study on solving cracking around molded holes in an EPDM rubber component through mold optimization, precision hole forming, material testing, and production quality control.

Following customer feedback regarding mold growth on electric toothbrushes after a period of use, our company promptly established a dedicated technical team to conduct an in-depth analysis of the root causes of mold formation and to initiate systematic research focused on material formulation and anti-mold performance.

In March 2026, our company engaged in in-depth technical exchanges and discussions with a long-term cooperative supplier to address the efficiency bottlenecks and process challenges in the post-process gating and punching operations. The two parties exchanged design concepts and process expertise extensively, focusing on key technical aspects such as punching precision, operational cycle time, die adaptability, and automation integration. Based on these discussions, a collaborative direction was established to jointly develop an integrated post-process gating and punching machine.

March 2026 – In response to customer requirements for enhanced product wear resistance, our company launched a dedicated technical research initiative in March 2026. Through multiple rounds of formulation design and systematic process optimization, the project team conducted in-depth experiments focusing on material composition, ratio optimization, and molding processes, ultimately establishing an optimized solution with exceptional wear-resistant performance.
