uniway — Hot Runner Systems
TECHNICAL SUPPORT

Our Work Does Not End at Delivery — It Continues Throughout Production

From system selection to commissioning, from troubleshooting to spare parts supply, we provide technical support throughout the entire service life of your hot runner system. Field service across Türkiye, with a technical team reachable 24/7.

The Three Stages of Support

01

Before the Sale — Choosing the Right System

We determine the combination of nozzle, manifold and temperature controller together with you, based on part geometry, material and cavity layout. The cost of a wrong choice is paid after production starts.

02

Commissioning — First Start-Up

After the system is mounted in the mold, we support you through the first heat-up, zone settings and initial start-up.

03

Throughout Production — Ongoing Support

For problems that arise during production, we are there with troubleshooting, field service and spare parts supply.

Common Situations and First Checks

This list is not a repair manual; it is a starting point that shows where to look first.

Drooling or stringing at the nozzle tipPossible causeTip zone temperature too high, insufficient decompressionFirst checkReview the tip zone temperature and the decompression setting
Gate mark, flash or cold weld line at the gatePossible causeGate zone temperature too low, or tip type not suited to the materialFirst checkCheck the gate temperature and the tip type–material match
Unbalanced filling between cavitiesPossible causeManifold balancing issue or temperature differences between zonesFirst checkCompare zone temperatures and review the balancing
Residue during colour or material changesPossible causeDead spots in the flow channel or insufficient purgingFirst checkReview the changeover procedure and flow channel cleanliness
A zone does not heat up or the temperature driftsPossible causeFaulty heater or thermocouple, poor cable/connector contactFirst checkMeasure the heater resistance and check the thermocouple connection
The controller raises a zone alarmPossible causeReversed thermocouple polarity or incorrect zone assignmentFirst checkVerify thermocouple polarity and the zone-to-nozzle assignment
Plastic leakage in the systemPossible causeAssembly temperature / thermal expansion balance, tightening valuesFirst checkReview the heat-up procedure and the assembly tightening values

If you have identified the symptom, get in touch — let's assess the system and the controller together.
