Our Heritage: 2006 to Today

Guangchenxin (GCX)

Guangchenxin (GCX) builds every cap it sells at one facility in Liaobu, Dongguan. Our die-casting heritage dates to September 2006, when our founders established Changbao Hardware Factory (东莞市寮步长宝五金制品厂), a zinc alloy die-casting workshop. In January 2013 the family formalized the business as Dongguan Yihan Hardware Products Co., Ltd. (东莞市亿晗五金制品有限公司). On June 28, 2017, the current legal entity — Dongguan Guanchengxin Metal Products Technology Co., Ltd. (东莞市冠铖鑫金属制品科技有限公司) — was registered, and the GCX brand, all export contracts, and every quality certificate we hold have belonged to this entity since.

One factory, one team, two registered entities. Guanchengxin and its affiliated company Yihan operate side by side at No. 5 Ximen Street, Shilongkeng, Liaobu Town, Dongguan — the same production floor, the same engineering and QC staff, the same management team. Whichever entity appears on your paperwork, your caps are cast, finished, and inspected by the same people, on the same lines, under the same quality system that has run since 2006.

Why we state this openly: some suppliers blur their history. We publish our registration details — legal name, registration date, and certification numbers — so your QA team can verify every claim against public records: the National Enterprise Credit Information Publicity System for the company record, and CNAS plus our certification body for the ISO certificates listed on our Certifications page.

When buyers ask “how long have you been in business?”, the honest answer is: two decades of die-casting heritage since 2006, under the current legal entity since 2017.
