Visual Counting and Weighing Machine for Small Parts

What This Machine Does

Counting small parts by hand is slow and error-prone - and a pure counting camera cannot confirm weight. This compact unit combines one camera with a weighing sensor to count and verify parts at one station, which is what packing lines and inventory control need when both the piece count and the batch weight matter. Configuration facts below come from the Shengyi New Material (Huzhou) Co., Ltd. brochure. Details are also on the counting and weighing machine page (/products/counting-visual-weighing-machine).

Key Specifications at a Glance

• Machine size: 420 x 250 x 563 mm.

• Configuration: 1 camera + weighing sensor.

• Weighing accuracy: +/- 0.03 g.

• Parts handled: Precision hardware, rubber seals, sealing plugs, medical accessories, automotive parts, electronic components, magnetic materials, food, ceramics, jewelry, buttons, plastics.

All specifications above come from the Shengyi New Material (Huzhou) Co., Ltd. machine brochure and are confirmed per configuration at quotation.

Why Counting Plus Weighing in One Station

Count and weight answer different questions: the camera answers how many pieces left the line, the sensor answers whether the batch weight matches what that count should weigh. Doing both at one station helps close the gap where a counting-only check would pass a batch whose weight does not match the count - mixed or wrong parts are caught only when their weight differs. The compact frame keeps the station small enough for a packing bench.

Parts It Handles

The list above shares one factor: small parts packed or inventoried in batches. Confirm your specific part and batch size with the factory so the counting configuration matches - counting speed depends on part size and feeding, and is confirmed on samples rather than quoted as a fixed rate.

Accuracy and Limits

Weighing accuracy is +/- 0.03 g per the brochure. For very light parts or very large batches, confirm your parts and batch weight range with our engineers so the configuration matches - the accuracy figure is the machine's, and your acceptance criteria should be set on your own samples. If you are drafting those criteria, start with how to define OK/NG defect criteria (/posts/defining-defects-ai-visual-inspection).

Where It Fits on the Line

As a parts counting machine, it sits on packing lines and inventory control where pieces must be counted and weighed at one station. It does not inspect surface quality or dimensions the way a turntable machine does - the HZXX-JC01 standard model (/posts/hzxx-jc01-single-table-inspection-machine) is the complementary machine for appearance inspection, and the two usually sit at different points of the line.

How It Compares with Other Machines

• The integrated packaging machine (/products/integrated-packaging-machine) inspects, counts and packs in one machine - choose it when the whole flow must be automated end to end.

• The HZXX-JC01 standard model inspects appearance and dimensions on a turntable - choose it when surface quality is the requirement.

• This counting and weighing unit is the standalone station - choose it when your line already packs and inspects elsewhere, and the missing link is batch verification.

What to Prepare Before You Ask for a Quote

Prepare: the parts you count and weigh, the batch sizes you pack, and your tolerance for count and weight errors. Send samples so the factory can confirm the counting configuration, the counting speed and the batch range on your actual parts at quotation.

Frequently Asked Questions

Which parts does it handle? Small parts packed or inventoried in batches - precision hardware, rubber seals, sealing plugs, medical accessories, electronic components and more, per the brochure's list.

How accurate is the weighing? +/- 0.03 g with a single camera plus weighing sensor on a compact 420 x 250 x 563 mm frame.

How is this different from a plain parts counting machine? A counting-only machine verifies quantity; this unit adds a weighing sensor, so a batch whose weight does not match the count is caught - when the weight differs, mixed or wrong parts surface.

What batch sizes can it verify? Confirm your batch size and weight range with the factory; the configuration is matched to your parts and confirmed on samples.

Does it inspect surface quality? Not per the brochure's configuration - it counts and weighs; appearance and dimensional checks are not part of its listed scope.
