The Spirit of 協和 (Xiéhé) — Our Journey to High Horizon

A Heritage of Accord

Our story begins with the principle of 協和 (Xiéhé), meaning Concord and Accord—a philosophy of harmony and collective progress. It was upon this foundation that our founder, Leong Kam Yoon, established Hip Hoe Engineering. The name “Hip Hoe” was a phonetic tribute to these characters, signifying a commitment to building lasting partnerships through integrity and engineering excellence.

Evolution to High Horizon

As we advanced, this legacy of craftsmanship evolved into HH Precision. Under Mr.Leong’s guidance, we became synonymous with technical mastery in mould making. Today, we have moved beyond the phonetic name “Hip Hoe” to embrace High Horizon as our credo. This identity reflects our vision to achieve greater heights of engineering excellence while honoring the “Accord” established at our founding.
