Fifteen companies have filed prospectuses to Hong Kong's stock exchange this week for listings worth over $7 billion combined.
They include 14 Chinese firms, including semiconductor maker Nexchip, and Dtech, which manufactures micro-cutting tools.
Their efforts to raise funds there are in line with what analysts view as a deliberate push by Beijing to use the capital markets to attract the overseas capital needed to finance national technology goals.
Luxshare is set to sell 383.5 million shares at a maximum offer of HK$63.30 each, aiming to raise HK$24.3 billion ($3.1 billion), according to its filing on Tuesday.
If successful, that would surpass Chinese circuit-board maker Victory Giant Technology, which raised $2.6 billion in its Hong Kong debut in April.
Luxshare, which is headquartered and listed across the border in Shenzhen, is China's largest provider of precision intelligent manufacturing solutions, and the fifth-biggest globally, according to consultancy Frost & Sullivan.
Its products include automotive electronics, and communication and data centres.
The firm said it would put about 65 percent of the proceeds from its Hong Kong listing towards upgrading production bases and enhancing smart manufacturing capabilities.
Nexchip, China's third-largest chipmaker, hopes to raise HK$7 billion from its listing, while drill bits manufacturer Dtech is seeking HK$4.8 billion, their filings said.
"There's been a conscious effort by Beijing... to have the capital markets play a larger role in financing Chinese innovation," Han Lin, China country director for The Asia Group, a consultancy, told AFP.
US-China tensions have positioned Hong Kong -- whose currency is pegged to the US dollar -- as a critical venue for Chinese firms wanting "to access global investors... needed to finance China's technology aspirations", Lin said.
Data from the Hong Kong exchange show it is processing nearly 500 applications for listings.
Accounting giant Deloitte said this month that about 150 technology firms are planning to raise funds in Hong Kong, adding that a pipeline of Chinese industry leaders will continue to drive the trend.
