June 30 (Reuters) - Five Chinese technology and advanced

manufacturing companies launched Hong Kong listings on Tuesday

to raise up to HK$44.1 billion ($5.6 billion), one of the

busiest days for new share sales this year, according to their

company filings.

The biggest of the five offerings is Shenzhen-listed Apple ( AAPL )

supplier Luxshare Precision Industry, looking to

raise up to HK$24.27 billion ($3.15 billion) after contemplating

a Hong Kong listing for more than a year.

The rush of new deals announced on Tuesday adds to a run of

Chinese companies turning to Hong Kong for fresh capital as

Beijing encourages more domestic champions to list close to

home.

There has been $22.45 billion worth of new listings in Hong

Kong in the first half, up nearly 57% from a year earlier,

making it the busiest start to the year in five years, according

to LSEG data.

Luxshare is selling 383.5 million shares at a maximum offer

price of HK$63.28 apiece, according to its prospectus. The final

price will be set on July 8, with trading set to commence the

following day. The company manufactures electronic devices,

including routers, wireless charging modules and video

conferencing equipment.

Chaozhou Three-Circle, which makes electronic ceramic

materials and parts used in electronics, cars and chip

equipment, is seeking up to about HK$7.16 billion, according to

its prospectus.

Nexchip Semiconductor, which manufactures chips designed by

other companies, said it would seek up to HK$6.98 billion.

Guangdong Dtech Technology, a maker of tiny drill bits and

other tools used to produce printed circuit boards, is aiming to

raise up to HK$4.80 billion, its filings showed.

Rokae (Shandong) Robotics Group, the smallest of the five

deals, said it would sell 23 million shares at HK$38 each to

raise about HK$875 million. The company makes industrial robots,

collaborative robots that can work near people and newer

AI-linked robots.
