Semi Automatic Capping Machine

Semi Automatic Capping Machine is a versatile, compact machine that combines manual and automatic operations. It is ideal for small to medium batch production of syrups, oral liquids, tonics, and other products in the pharmaceutical, cosmetic, and food industries.

Step-by-Step Working Process:

• Manual Bottle Placement The operator manually places the filled and stoppered bottle (with the screw cap loosely placed on the bottle neck) under the capping head. Some models come with a slide track or small conveyor to help position the bottle correctly.
• Cap Placement The operator manually places or positions the screw cap (plastic or metal) on the bottle neck. In some configurations, the cap can be pre-placed by the operator before moving the bottle under the head.
• Capping Operation Once the bottle is properly positioned, the operator activates the machine using a foot switch or push button. The capping head descends automatically and rotates with controlled torque. The chuck grips the cap and tightens it to the preset torque value.
• Torque Control The machine uses an adjustable torque control system (mechanical or magnetic clutch) to ensure the cap is tightened uniformly. This prevents over-tightening (which can damage threads) or under-tightening (which can cause leakage).
• Completion & Removal After the cap is securely tightened, the capping head automatically retracts upward. The operator removes the capped bottle and repeats the process for the next bottle.

Key Highlights of Operation:

• No manual pressure is required for tightening — the machine handles the threading and sealing automatically.
• The cycle is activated by a foot switch, making operation easy and less tiring for the operator.
• Changeover for different bottle and cap sizes is quick with adjustable height and change parts.
• The machine is equipped with safety features like overload protection and emergency stop.
