Combination weigher

When sourcing a combination weigher, you must prioritize weighing accuracy (typically ±0.1-1.5g) and speed (measured in weighings per minute, WPM). Ensure the machine features IP65 or IP67 waterproof ratings if you are handling frozen or wet products to allow for high-pressure washdowns. Additionally, check for stepper motor drive systems for precise bucket control and load cell sensitivity to ensure consistent portioning.

The number of heads directly impacts speed and accuracy. A 10-head weigher is suitable for standard speeds (up to 60-70 WPM), while a 14-head or 20-head weigher is ideal for high-speed applications (100+ WPM) or mixing multiple products. More heads provide more mathematical combinations, which significantly reduces product giveaway and increases profit margins over time.

All contact parts must be made of Food Grade Stainless Steel (SUS304 or SUS316). For sticky products, look for dimpled (teflon-coated) plates to prevent adhesion. Ensure the equipment carries CE certification for the European market or UL/FDA compliance for the US. Verification of ISO 9001 manufacturing standards is essential to guarantee long-term mechanical reliability.

Yes, professional suppliers on Made-in-China.com provide weighers that support standard signal protocols (Modbus/CANbus) to synchronize with Vertical Form Fill Seal (VFFS) machines, rotary pouch machines, or canning lines. Always confirm if the supplier provides customized timing hoppers and mounting brackets to fit your specific conveyor height and packaging interface.

Request a Factory Acceptance Test (FAT) via video call before final payment. Send samples of your actual product (e.g., snacks, hardware, or frozen food) to the supplier in China for a trial run. Ask for a detailed testing report showing the standard deviation and actual speed achieved with your specific material.

Industrial weighers are precision instruments; ensure the contract specifies seaworthy vacuum packaging and wooden crate reinforcement to prevent moisture and vibration damage. Negotiate for remote technical support or the provision of installation videos and English-language PLC interfaces. For large-scale setups, verify if the supplier can dispatch engineers or has local service partners in your region.

Use Secured Payment terms offered by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. Insist on a 12 to 24-month warranty on core components like the mainboard and load cells. Always request a wearing parts kit (springs, gaskets, and sensors) to be included in the initial shipment to avoid production downtime during cross-border logistics delays.
