Purchasing & supplier management · Plastics & injection molding
Keep resin in the silo and presses running.
A resin's lead time triples and the buyer is qualifying an approved alternate before a silo runs dry. One missed reorder idles every job that runs that grade.
The reality
Resin buying is a continuity problem.
A supplier pushes the lead time on a base resin from two weeks to six, the buyer scrambles to find an equivalent grade, confirm it's approved for the part, and place a PO before the silo runs out. Colorant and additive orders slip through the cracks until a run can't start.
The operator owns resin and colorant procurement end to end: it tracks consumption against silo and bin levels, watches supplier lead times, raises POs ahead of need, qualifies an approved alternate when a grade goes long, and tracks vendor performance — so material is always there and a press never waits on resin.
How the operator runs purchasing & supplier management
Resin · PP homopolymer
below min- Silo level 18% vs reorder 30%
- Scheduled runs netted against on-hand
- Reorder triggered
01Track consumption and levels
Watches resin and colorant on hand against run demand and reorder points across silos and bins.
PO-4418 · Confirm
confirming- PO placed for 40,000 lb
- Lead time confirmed at 2 weeks
- Ship date acknowledgement requested
02Place and confirm the PO
Raises the PO to the supplier, confirms price and lead time, and chases the acknowledgement and ship date.
Alternate · grade sub
qualifying- Lead time extended to 6 weeks — flagged
- Approved equivalent grade identified
- Same-day PO placed to alternate supplier
03Qualify an alternate
When a grade goes long, sources an approved equivalent resin, confirms it's released for the part, and places a same-day PO.
The outcome
−55% of time on resin PO and follow-up
Material available, no production stoppages.
- Reorders fire ahead of the silo running dry
- A long lead time gets an approved alternate, not a stopped press
- Vendor performance is tracked, so the next PO goes to who delivers
