Shanghai Fanchi-tech Machinery Co., Ltd.’s solution to bottling production line quality inspection challenges

Traditional, separate inspection equipment often faces three major pain points on high-speed bottling lines: missed metal foreign bodies leading to customer complaints, weight errors causing compliance risks, and poor bottle fit causing line downtime. Our Combo Metal Detector and Checkweigher is designed to address these pain points.

Core Technology Breakthroughs
1. Dual-Mode Detection Engine
Integrates high-sensitivity metal detection (detection accuracy down to 0.3mm stainless steel) and a dynamic weighing system (accuracy ±0.5g), completing dual quality inspections in a single pass at speeds up to 300 bottles per minute.

2. Unique Bottle-Stop Design
Patented guide rail system ensures smooth passage of even uncapped bottles through the inspection channel.
Adaptive lane rejection mechanism automatically triggers pneumatic straightening for upside-down or tilted bottles.

3. Intelligent Production Line Compatibility
Supports all bottle materials, including PET, glass, and aluminum cans.
Modular structure accommodates bottle diameters ranging from 80-150mm.
Contact components are made of food-grade 304 stainless steel.

Tested Data from a Multinational Beverage Group:
After implementation at its Indonesian factory:
Metal detection rate increased to 99.99% (meets BRCGS AA requirements).
Annual quality costs reduced by $256,000.
Production line changeover time reduced by 70%.

Customer Reviews:
Customers particularly praised the Combo Metal Detector and Checkweigher's triple protection system: The metal detection module's spectrum recognition technology can distinguish the difference in gamma values between 304 stainless steel and the raw material of the product; the dynamic weighing system's temperature compensation algorithm overcomes the effects of tropical climates; and most importantly, the patented guide track design maintains a pass rate of 320 bottles per minute when filling high-viscosity products such as coconut water.
