Preform Inspection System
Catch preform defects before they become bottles.
PIS100 inspects PET preforms right after injection moulding — gate, body and neck finish — so contamination, bubbles, short shots and neck damage are removed before blow moulding or shipment.
Overview
Clean preforms, fewer bottle rejects.
A single bad preform can burst in the blow-moulder or leak in the field. PIS100 checks every preform at the gate, along the body and around the neck finish, and removes defective parts before they reach the blow-moulding line or the customer.
Each mould and colour is taught once as a recipe, and defect images and counts help the moulding team fix problems at the source.
- Gate, body and neck-finish inspection
- Detects contamination, bubbles and short shots
- Thread and sealing-surface check
- Automatic rejection with image log
How PIS100 inspects
1. Feed
Preforms singulated onto the inspection conveyor
2. Gate view
Injection point, holes and stringing
3. Body view
Bubbles, black specks, haze and contamination
4. Neck view
Threads, support ring and sealing surface
5. Decision
Each defect classified against the recipe
6. Reject
Defective preforms removed automatically
Defect detection
What PIS100 detects.
Every preform is checked after moulding. Defective preforms are flagged and rejected automatically.
Black specks
Burnt material and dark particles in the wall.
Bubbles & voids
Air bubbles and voids in the body or base.
Short shot
Incomplete filling of the mould.
Gate defects
Long gate, hole or stringing at the injection point.
Neck & thread damage
Damaged threads, support ring or sealing surface.
Ovality & deformation
Out-of-round or bent preforms.
Haze & crystallinity
White haze and unwanted crystallisation.
Colour variation
Wrong colour or shade outside the limit.
Key features
Built for PET preform lines.
Gate, body & neck cameras
Dedicated views cover the whole preform in one pass.
Recipe teaching
Teach each mould, weight and colour once and recall it in seconds.
Automatic rejection
Defective preforms removed in step with the conveyor.
Defect trends
Counts and images per defect type help fix problems at the mould.
Fits existing lines
