Inspect for scoring, abrasion, or excessive clearance. Worn components cause inconsistent shot volumes and poor melt quality.
Measure for parallelism ; misalignment can damage molds. Look for cracks, pitting, or rust on the tie bars.
Ensure the tie-bar spacing and platen size can physically accommodate your molds. Check the ejector stroke and pattern to ensure parts can be removed without damage. Drive Type: buy used injection molding machine
A well-documented history is often more important than the machine's age. Used Injection Molding Machine Buying Guide - Meadoworks
Never buy a machine based on photos alone. Use this checklist during a physical inspection: Inspect for scoring, abrasion, or excessive clearance
Cheaper upfront and easier to repair, but uses more energy.
This is the pressure required to keep the mold closed during injection. A common rule is to add a 10–20% safety margin to your calculated minimum to prevent "flash" (excess plastic). Look for cracks, pitting, or rust on the tie bars
Verify the touchscreen responsiveness and check for any active error codes. Note that obsolete controls are extremely difficult to service.
