Customer & Material Customer: Ningbo Huawei Precision Manufacturing Co., Ltd. Material: Small cylindrical metal inserts (3mm in diameter, 8mm in length, dry surface, non-sticky)   Original Problems The workshop space was tight – a standard vibratory bowl feeder occupied too much floor area and could not fit into the existing line. Additionally, the cylindrical parts tended to roll and accumulate, causing unstable feeding with conventional bowls.   Adopted Solution – Double-Line Feeding System Linear circulation feeding saves approximately 40% of floor space compared to a standard vibratory bowl feeder. Dual lanes transport parts simultaneously, doubling throughput. Ideal for small, cylindrical parts, reducing rolling and jamming.   Implementation Results Successfully installed in a narrow station only 400mm wide. Stable double-line output speed: 120 parts per minute (60 parts/min per lane), meeting the customer’s capacity requirement. No jamming or overlapping of cylindrical parts; the system ran continuously for 72 hours without failure.   Customer Feedback “The double-line feeding solution perfectly solved our problems of limited space and rolling parts. It is also much quieter than a standard vibratory bowl feeder.   Key Success Factors Dry, non-sticky material – fully leverages the advantages of linear circulation feeding. Guide channels for cylindrical parts, combined with dual-lane separation, prevent pile-ups.

Customer & Material Customer: Zhejiang Liming Material: Thin metal sheets with an oily/sticky surface (sheets readily stick to one another)   Problem Description A push plate feeding system was adopted, consisting of a sheet pusher plus a return screening plate at the end of the linear feeder. Due to the sticky surface, the push plate could not effectively separate the sheets: When the push plate retracted, stuck-together sheets were pulled back into the hopper, resulting in empty strokes. The sticky residue gradually accumulated in the push plate gaps and clogged the screening holes.   Result The system required cleaning every 2 hours, making it slower than manual feeding. Sheets became deformed, and eventually the motor overloaded and burned out.   Customer Feedback We wanted to improve efficiency, but everything stuck to the machine – it was completely unusable.   Direct Losses Approximately 3,500 sheets were scrapped, representing a material loss of over 10,000 RMB. Motor repair plus production downtime caused a 2-week project delay.   Lessons Learned Push plate feeding is unsuitable for sticky thin sheet materials – it works only for dry, non-sticky, long-rod type parts. For oily/sticky materials, alternative methods such as pneumatic separation, PTFE coating, or ultrasonic vibration must be used, and physical sample testing should always be conducted beforehand.
