Hello everyone,
I'm a long time subscriber but infrequent poster. I've asked for help in the past and this forum has never let me down.
I have a 94 van dorn 170 ton, 14 oz molding machine with a Pathfinder EL control. This machine has been sitting idle for over 2 years but it needs to run...
Hello everyone. It's been a while since I posted here but I know where to get solid advice when I need it. :)
Does anyone know of company that offers repair parts for older injection molding machines? I have an old Cincinnati Milacron (1974) 250 ton Extended Platen machine that needs a new...
Thanks everyone. Making the connectors/tabs/gates(?) thinner really isn't an option right now. I'm hoping to make good parts by trying alternate resins and, to a limited extent, playing with the process. Someone else here mentioned trying a lower molecular weight (sp. gr.). I think we'll...
Hi Everyone:
I have inherited a mold that produces a tamper evident cap almost identical to those used in plastic milk/water jugs. The cap has a ring that sits below the cap body that must break away from the cap at 9 evenly divided points along the circumference when the cap is initially...
The lead read "PC". The repair shop said that there was a thermistor installed but they had forgotten to install it initially. They sent a guy out he installed it here at my shop. The motor seems to be running just fine now.
Thank you moira. I'm the owner of a modest injection molding company. So basically, I'm the maintenance man, purchasing agent, set up man, salesman, tooling engineer, expert troubleshooter...you get the picture. I do have a few people working for me such as operators and foreman. But the...
I installed the motor back in the machine and connected the power to motor...correctly!!! After pump ran for a few minutes and all of the air was bled from the hydraulic system the motor/pump combo run nice and smooth. The thermistor (165C rating) is connected to the PLC and that should take...
Thank you everyone. A technician from the repair shop is installing one right now as I type. They admitted that it was their fault for not installing one. I hope to have this motor back in the machine and connected by the end of the day. Again, thanks everybody.
I haven't traced the wires yet, but one of the wires coming out of the motor was labeled "PC". The two wires from the control panel are labeled but I'm having a hell of a time finding their reference in the machine schematics. If it is a connection for a thermocouple then I can do with out it...
The repair shop called me today and informed me that I indeed have the motor hooked up incorrectly; the motor is a delta not star. that explains why I burnt it out. Please keep in mind that there's no info on the face plate. next time I will do a continuity check. Expensive lesson on my...
The shop insisted again that I had the connection correct. I'm thinking the bearings on visual inspection looked fine but under rotation and load they were not. The motor was rewound and the bearings will arrive/be installed on Monday.
I believe I mentioned that the pump had been rebuilt a...
