Plastic part feeding
Plastic moulded parts feeding
Plastic moulded parts can be good bowl-feeder candidates, but static, flash, surface finish and part balance must be checked with real samples.
Why plastic moulded parts need a sample-led feeding review
Plastic mouldings can look simple but behave differently in a vibratory bowl depending on ribs, flash, mould split lines, surface finish, static, weight and centre of gravity. Real samples are therefore essential before Lancing can confirm a feeder route.
| Issue | What it can affect | What to send or confirm |
|---|---|---|
| Static attraction | Parts sticking together, clinging to tooling or failing to settle into the track. | Material, surface finish, production environment and any anti-static requirement. |
| Flash or mould variation | Jams, inconsistent orientation and rejection of otherwise acceptable parts. | Good parts, worst-case parts and acceptable variation from production. |
| Surface marking | Cosmetic damage on visible faces or functional contact areas. | Mark-sensitive areas, finish requirement and acceptable contact surfaces. |
| Lightweight geometry | Bouncing, floating, double-feeding or poor track control. | Weight, dimensions, natural resting faces and required exit orientation. |
| Downstream presentation | Whether the part needs a chute, escapement, nest or pick point. | Receiving machine drawings, height, pick face and confirmation sensor requirement. |
Plastic part feeder questions
Can vibratory bowl feeders handle plastic mouldings?
Vibratory bowl feeders can handle many plastic moulded parts, but suitability depends on geometry, weight, finish, static behaviour and the orientation needed by the downstream process.
What makes plastic parts difficult to feed?
Common issues include static, burrs or flash, very light weight, similar-looking faces, nesting, tangling and surface marking. Those issues are best assessed with production samples.
Can a feeder avoid marking cosmetic plastic parts?
Marking risk can often be reduced through tooling shape, lining, feed settings and contact-point planning, but it must be checked against the actual part and acceptable finish.
Should I send drawings or real samples?
Send both where possible. Drawings help an early review, but real samples show static, friction, balance, surface finish and variation that drawings do not prove.
Need this checked against your application?
Send sample parts, drawings, required orientation, output target, discharge height and downstream machine details. Lancing can review the practical feeder route before quotation.
