Three sealing methods are suitable for a liquor filling machine: pressing, rolling, and screwing. Pressing the T-cork stopper into the bottle neck. Rolling produces a metal cap over the glass thread. Unscrewing caps from the finish using a pre-threaded cap. For 100–500 ml glass bottles, the Innofluid liquor filling and sealing machine does all three.
Innofluid has been working on fluid handling R&D for 20 years. All numbers below are taken from the respective product info sheets. This guide explains how each closure works. It also clarifies what bottle each one requires and what the figures signify in real-world situations.
What Does a Liquor Filling and Sealing Machine Do?
The primary filling equipment of a liquor bottling production line is a liquor filling and sealing machine. It fills the bottle, puts the closure on, and seals it. Pressing, rolling, or screwing is used to seal. The filling and sealing are done on one machine; therefore, it is small in its build.
The machine accepts 100-500 ml glass bottles. But that decision of closure is up to the bottler, not the machine. It decides what can go through the bottleneck.

Pressing, Rolling, or Screwing: How Does Each Method Seal?
Each method closes a bottle in its own way. Each one also needs a matching neck shape.
Pressing: Seating a T-Cork Stopper
By inserting a cork stopper into the bottle's neck, pressing seals it. The glass wall grips the cork. Not held by a thread, but by friction. Premium spirits often use T-cork stopper pressing. Part of the ritual involves opening the bottle by hand. Force must be kept uniform. Too much pressure drives the cork in too far.
Rolling: Forming a Metal Cap Onto the Glass
By forming a soft aluminum cap over the glass thread, rolling seals a bottle. First, the cap is put on the neck. The metal is then pressed into the shape of the thread by microscopic rollers. So the closure happens in situ; it is not prepared up front. This procedure leaves a tamper evident strip. That’s why brands like gin, vodka, and whisky prefer it. For rolled caps, the neck must be built.
Screwing: Turning a Pre-Threaded Cap
By attaching a ready-made threaded cap to the bottle neck, screwing it seals it. The machine sets the torque, the power of turning. When it comes the cap is completed, thus nothing is created on the line. It is the setting of torque that counts. Too tight, and the bottle leaks. Too tight, and the glass can crack. Screwing requires the least amount of setup time of the three.

How Does One Frame Handle All Three Sealing Actions?
A single frame handles all three motions. We don’t have two stations for filling and sealing; it’s all built into one machine. Here is the idea of the monoblock filling and capping machine. One pass fills and seals the bottle.
The true gain is one less transfer point from fill to seal. That works for high proof spirits. Open bottles spray when moved.
Why One Less Transfer Point Helps
Open bottles spend less time moving between stations
Fewer handovers mean fewer knocked or tipped bottles
One footprint instead of two frees floor space
A single frame means one set of controls to learn

This is a mid-speed liquor bottle filling machine, and it fills between 40 and 60 bottles per minute. It is more suitable for artisan and regional distilleries than major facilities. This line covers 100 – 500 ml, miniatures, half-bottles, and 500 ml formats. Bottles larger than 500 ml are not inside that range. This amount excludes a 700 ml and a 750 ml bottle.
The sealing rate is above 99%. Compare it to your own reject limit before committing. The precision of the measurements is given as 0–2%. This is the fill tolerance of this unit. Power supply 380V, 50Hz, three-phase, four-wire 2kW. Check this out before they purchase, for buyers on 60 Hz or single phase electricity.
How Do You Pick the Right Sealing Method for Your Bottle?
Pick the method your bottle neck already supports. Then check it against your brand and your changeover pattern. Glass comes first, because it cannot be changed later.
Start With the Neck, Not With the Machine
A cork bore cannot take a screw cap. A threaded neck will not hold a cork. Ask your glass supplier for the finish drawing first. Do that before you shortlist any liquor bottle filling equipment. That one drawing saves weeks of guesswork on both sides.
Match the Closure to How the Brand Reads
Cork reads as premium and slow. Screw caps read as easy and resealable. Rolled aluminum sits between the two. It also adds clear proof of tampering. For glass bottle filling and capping, the closure is part of the product story. It is not just a technical choice.
How Often Will You Switch Closures?
A distillery running one closure all year has simple needs. A contract bottler switching products each week does not. Frequent switching favors screw caps, since setup is simple. Steady single-format work makes it easy to justify cork or rolled caps.
Here is the short version. Let the glass rule out what is not possible. Then let the changeover frequency pick from what is left.
Where Does This Unit Sit in a Full Bottling Line?
This unit is the liquor-specific member of Innofluid's wider Liquid Filling Machine range. Buyers comparing an automatic liquor filling machine with other formats often want to see the full range first.
Related Units and Their Published Output
Filling and Capping machine - 6,000 bottles per hour
Straight Line Filling Machine - 2,500–3,600 bottles per hour

Read together, the list shows one thing. Spirits bottling equipment sits inside a wider liquid handling family.
Which Errors Do First-Time Buyers Make Most Often?
The most common error is picking the sealing method before checking the bottle neck. A few others come up often:
Giving a bottle size in millilitres, but never sending the neck drawing
Assuming a 500 ml machine will stretch to a 700 ml bottle
Missing voltage and frequency, then needing a transformer on arrival
Comparing speed in different units, such as per minute against per hour

Häufig gestellte Fragen
Can one liquor filling machine do pressing, rolling, and screwing?
Yes, the Innofluid unit does filling, capping, pressing, rolling, and screwing and sealing. The action used on any run depends on the closure and the bottleneck.
Cork, rolled aluminium, and screw caps each need a matching neck
Confirm your closure type with the supplier before you order
What bottle sizes does the Innofluid liquor filling machine accept?
The stated range is 100–500 ml glass bottles. Sizes outside that range are not covered by the published spec.
Miniatures, half bottles, and 500 ml formats fit the range
For 700 ml or larger, ask Innofluid rather than assume
How fast is this liquor filling and capping machine?
Output is 40–60 bottles per minute. That works out to roughly 2,400–3,600 bottles per hour. The real figure depends on bottle shape, closure, and handling.
Compare the number with your own daily target
Check the unit used before you compare two quotes
What sealing rate should a spirits bottler expect?
The published sealing rate for this unit is above 99%. Treat it as the benchmark for your own reject limit.
Higher-value products usually need tighter internal limits
Cork, rolled, and screw closures each fail in their own way
Does the machine need three-phase power?
380V, 50Hz, three-phase, four-wire, 2 kW is the specified power supply. Before making a purchase, sites outside of the 50 Hz range should check this.
Talk to your electrician to be sure of the voltage, frequency, and phase.
During the inquiry step, notify the provider of any discrepancy.
Is the filling and sealing combined or separate?
A single machine does both filling and sealing. The structure is described as compact, and the design is advanced in the published description.
Two separate stations are replaced with a single frame.
Open bottles of high-proof liquor need fewer handovers.
Fazit
First, the bottle chooses the sealing method. The remainder is shaped by brand position and switching patterns. The three methods of pressing, rolling, and screwing are distinct in their applications. Success does not always come from a single strategy.
Are your bottles 100 milliliters to 500 milliliters in capacity? Can you have the filling and sealing done on a single frame? In such a case, you should check out the Innofluid liquor filling and sealing machine right now. A single published specification addresses all three closure actions.
