June 2019
Summer is right around the corner and many plastic molders will have a summer shut down as a time for refreshing and recharging for most people. However, for the people that keep the tools running that make the plastic parts, this is the time to schedule tool repair, so the tools will operate within optimum parameters. Included in the repair of the tools is the inspection and or replacement of the hot runner components.
Evaluation of the nozzles and internal components.
If you are experiencing any injection issues, now is a good time to evaluate and clean the hot runner system. It is important to use a propane torch and not a MAPP torch because the hotter MAPP torch will overheat the spring and cause fatigue and failure.
Evaluation of the heaters and thermocouples.
Ring and cartridge heaters should be examined for frayed wiring, damage to the metal case, and loss of the wire seal on cartridge heaters. Frayed insulation may be repaired with high temperature electrical tape. If the conductor wire or metal case is damaged, the heater should be replaced.
Thermocouple examination is for frayed insulation, kinks and crushed areas on the metal sheath. As with the heaters, frayed insulation may be repaired with high temperature electrical tape. A thermocouple with kinks or crushed metal sheath should be replaced.
Nozzle refurbishment service.
I would also like to offer the FISA nozzle refurbishment service as an option, if you would like to send us your nozzles, recommended for AH series nozzles as the piston is more vulnerable to damage with improper removal. We will disassemble, clean and evaluate the components. We will send you a report of our evaluations along with a quote for the parts that need to be replaced. When you send us a PO to cover the refurbishment, we will reassemble your nozzles to optimum condition and return to you.
We do have an extensive inventory of all standard components in stock at our corporate headquarters in Shelbyville, Tennessee and we can ship 1-day ARO. Order your spare parts so you can have them in stock when you need them.
Until next month, be safe, keep your injection mold tools in optimum condition, and make good parts.
