Reversing the Crisis in 48 Hours: How Tomaster's Electric Tailgate Technical Team Saved Tank300's Overseas Customer
In February 2025, Max (a pseudonym), the head of an international trading company, flew to China urgently with 200 sets of problematic tailgate components. Previously, he had purchased Tank300 electric tailgate from another supplier, which had a 23% return rate due to seal failure and motor overload, and the overseas customer threatened to terminate the cooperation. By searching “Tank300 electric tailgate OEM solution” on Google, he contacted our factory - this crisis eventually became the starting point of our deep cooperation.
Chapter 1: Traceability of the problem - from customer despair to precise positioning
“We tested all the components, but could never find the core failure point”
--Marx team engineer
When Marks arrived at the factory with the problematic component, the technical team completed the full-link inspection within 3 hours:
Environmental simulation test: in -30℃ extreme cold/70℃ high temperature box, reproduced the motor torque drop 43% failure
Waterproof structure disassembly: found that the hardness of the original supplier's waterproof adhesive tape was not up to standard (measured 65 Shore A vs. demanded 75 Shore A)
Circuit analysis: the control module has no overload protection, resulting in motor burnout during voltage fluctuations.
Diagnostic report core conclusions:
▶ 72% of failures originated from defective seal assembly materials
▶ 18% due to control logic not adapted to Tank300 off-road conditions
