Where the HAI-8556 Sits in the Longsheng Range

Shantou Longsheng Industry Co., Ltd. builds three cup making platforms so a producer can match drive technology to product mix rather than compromise. The FS-8556 uses full servo motion, the HSS-8556 combines hydraulic power with servo control, and the HAI-8556 is the hydraulic machine: a mature, mechanically robust platform aimed at steady, high-volume runs of standard cup formats.

For a factory making one or two cup sizes around the clock, that simplicity is an advantage. Fewer control layers mean fewer parameters to disturb, and the hydraulic clamp holds forming pressure consistently through long shifts.

What the Machine Produces

With the right mold, the HAI-8556 forms and trims drinking cups and small containers in PP, PS, HIPS, PVC, PET, PLA, PE and biodegradable materials:

• Cold drink cups in 7oz, 12oz, 16oz and 24oz formats, plus 4oz tasting cups
• Thick-wall PP cups for hot drinks and milk tea
• Yogurt, jelly, pudding and mousse cups with flat rims for lid sealing
• Sauce and condiment cups, dessert bowls and ice cream cups
• PLA cups for markets that require compostable packaging

Mechanics That Matter on the Shop Floor

Three details decide whether a hydraulic cup machine earns its place on a line. First, the frame: a heavy welded structure absorbs forming shock so the trim edge stays clean over millions of cycles. Second, heating control: zone-by-zone temperature regulation keeps sheet sag uniform, which is what makes wall thickness repeatable. Third, the tooling interface: Longsheng manufactures precision molds in-house, so cavity count, rim profile and stacking pitch are defined together with the machine rather than adapted afterwards.

Choosing Between the Three Platforms

Full servo suits frequent size changes and the fastest cycles. Hydraulic servo suits heavy-gauge or deep-draw work. The hydraulic HAI-8556 suits producers who value mechanical reliability and straightforward maintenance, especially where local service technicians are trained on conventional hydraulic systems.

Company Background

Longsheng was founded in 1998 in Shantou City, Guangdong Province, and operates a 30,000 square metre plant with 25 authorised patents (1 invention, 24 utility model) as a high-tech enterprise.
