Repairing and maintaining a typical hot runner system takes mold maintenance skills to the next level.
While all mold repair work should be performed methodically and carefully, successful hot runner repair requires a higher level of precision, understanding and accuracy that can only be accomplished in a systemized approach that utilizes accurate documentation of the critical elements of manifold work
.Tooling in a typical hot runner system must be handled with great care while cleaning, inspecting and reassembling.
Methodical practices must be used to prevent potential disasters that could be just a wrench slip, pinched wire or forgotten bolt away.
Adding to the challenge is various processing techniques and resins that can have a huge effect on the performance, condition and maintenance practices concerning a hot runner system.
Attendees will learn how various hot runner systems function and the critical areas of each.
Attendees will troubleshoot, document and map out several manifold systems using an ohmmeter (supplied) while learning about Ohm’s Law and how it is applied during heater inspection.
Attendees will also learn how to review manifold histories then completely disassemble, clean, inspect, document and reassemble a multi-cavity valve gate and fixed gate system and learn how to determine what elements of the manifold should be included in setting up a PM program.In addition, common issues will be discussed and useful bench techniques will be taught that include:
Performance and maintenance characteristics of several popular brands of hot runner systems used today.
Working safely on hot manifolds.
Disassembly, cleaning and assembly techniques used at the bench.
Typical problems created through bad work habits—when to utilize extreme care.
Wiring how-to, splices, repairs, resistance checking, heater size verification, and replacement.
Business indexes report that hot runners are being used on 60% of all new molds built today. Add to that the thousands built years ago that are still in service today making products all over the globe. Practically every plastics molder deals with hot runner issues every-day. These issues can offset the many benefits of using these valuable systems if they are not properly maintained for optimal performance.
In today’s lean tool rooms, companies can’t take chances on success.
In our ToolingDocs® Hot Runner Maintenance and Repair Certification course, mold repair technicians will learn solid hot runner maintenance principles that can be applied immediately from instructors with decades of bench experience in the caring and feeding of hot runner tools. And, they will learn and practice these hands-on bench techniques in a controlled, safe and state-of the art shop.
