Unexpected Downtime, Avoidable Costs!

A customer recently asked us to inspect a brand-new blow moulding machine with parison control issues. Our technicians discovered metal contamination — metal trapped between the parison rod and mandrel — causing significant disruption. The parts had to be reconditioned, and the machine was offline for an entire week.
💸 The Impact:
Product weight and wall issues
Costly repairs or part replacements
A week of lost production
✅ Simple Steps to Prevent It:
Install Metal Detection
Use Lidded Material Bins
Inspect Recycled Materials Thoroughly
Protect your machinery. Avoid delays. Keep production moving.
