Capping machines can be divided into several types according to closure style, bottle size, and production environment. Below are three common types used for metal caps, aluminum seals, and screw caps.
Low-Bench Metal Anti-Theft Cap Sealing Machine
This machine uses a motor-driven rotating action to raise the base and press against the top of the cap. The locking device then automatically completes cap sealing. It operates entirely through mechanical principles, offering convenient operation, simple installation, reasonable structure, stable sealing quality, high production efficiency, easy adjustment, and simple maintenance. The machine also has functions such as sealing and thread pressing.
Main technical parameters: power supply 220V 50Hz, power 370W, electric operation, sealing diameter φ25–φ35mm, cap height 7–35mm, production capacity ≤20 bottles/min, applicable bottle height 70–330mm, overall dimensions 520×200×900mm, weight 65kg.
For such machines, the locking heads, pressure rollers, and bottle support bases are subject to repeated contact wear and require precise dimensional matching with the cap and bottle neck. Hansheng Automation can custom-machine these components based on customer drawings or sample parts.
Oral Liquid Cap Locking Machine
This machine is mainly suitable for sealing aluminum caps and pull-off caps on various glass bottles. It is not suitable for screw caps. It is often used as a temporary replacement model during equipment maintenance in the pharmaceutical, health product, chemical, and cosmetics industries, and is also an ideal choice for laboratories that need small-batch or trial sealing work.
Main technical parameters: power supply 220V 50Hz, power 50W, sealing diameter φ10–40mm, cap height 5–20mm, applicable bottle height 30–180mm, production capacity ≤20 cycles/min, weight 20kg, overall dimensions 350×250×650mm.
Handheld Electric Screw Capping Machine
This portable device is mainly used for opening or tightening various threaded caps. It is easy to carry and suitable for tightening or loosening bottle caps in different locations. The adjustable clutch effectively prevents cap damage and reduces wear on inner plugs.
Main technical parameters: capping speed approximately 25 bottles/min, main unit net weight 0.6kg/1.1kg, voltage 220V 50/60Hz, adjustable torque clutch, capping range 28–43mm. Optional ranges: small 20–33mm, medium 28–43mm, large 30–50mm, with only one size included with the machine. Power adapter dimensions 125×80×60mm, main unit dimensions 60×60×300mm.
