Plastic mouldings
Static, moulding flash, colour range, nesting and surface marking affect presentation.

Small parts counting machines.
Count clips, O-rings, springs, mouldings, connectors, terminals and miniature fixings into accurate batches for bags, kits, stock packs or assembly processes.
- Representative-part trials
- Defined batch acceptance
- UK project support
Direct answer
How do you count small components automatically?
A small-parts counting machine meters the bulk supply, separates components into a controlled presentation, detects each accepted part and creates a positive boundary at the required batch quantity.
For parts that cannot be reliably singulated, vision or a validated count-by-weight method may be assessed instead.
Component families
Small size is only one part of the problem.
O-rings and seals
Flexible parts can cling, roll or overlap and may need controlled contact materials.
Clips and springs
Interlocking and tangling risk can govern product depth and feeder technology.
Connectors and terminals
Fine features, orientation and damage risk may justify compact sensing or vision verification.
Caps, plugs and inserts
Stable repeat mouldings can suit vibratory, step, centrifugal or flexible feeding routes.
Miniature fixings
Fine screws, washers and pins require proven spacing and sensor response margin.
Trial inputs
Send production variation, not only ideal samples.
- Minimum and maximum dimensions and mass
- All colours, translucencies, finishes and suppliers
- Good parts plus known burrs, flash or contamination
- Parts after normal storage and transport
- Target quantities and sustained completed batches
- Bag, box, kit or assembly receiving condition
Risk-to-method map
Start with the dominant uncertainty.
| Application risk | Likely engineering response | Evidence required |
|---|---|---|
| Parts overlap or nest | Dedicated singulation and recirculation | Sustained feed test across all variants |
| Low optical contrast | Alternative sensor, lighting or vision | Signal margin under production conditions |
| Parts tangle | Low product depth, step or special separation | Refill and long-duration recovery test |
| Surface damage risk | Gentle feed path and controlled drop | Approved cosmetic acceptance samples |
Frequently asked questions
Direct answers for your specification.
Final suitability and performance depend on representative components, operating conditions and agreed acceptance criteria.
Ask about your component →What is classed as a small part for automatic counting?
There is no universal size threshold. Detection margin, geometry, mass, material, surface and how parts separate matter more than one dimension, so the real component set must be assessed.
Can tiny black or transparent parts be counted?
Often, but the sensing route must be tested. Fibre-optic, laser, background-suppression, transmitted-light or vision methods may be considered according to the material and presentation.
How are light components prevented from bouncing?
Track material, slope, vibration, air movement, drop height, chute design and controlled speed can reduce unstable movement. Trials show whether a reliable detection window can be maintained.
Can different small components run on one machine?
Compatible families may use recipes and adjustable or change tooling. Very different geometries can need separate dedicated feed channels, particularly where cross-contamination must be prevented.
Can small parts be counted into heat-sealed bags?
Yes. The counter can feed an automatic bagger or a supported open-bag station and exchange ready, complete and fault signals with the packaging equipment.
