Part 1: How to Prevent Nozzle Tip Leaks
Instead of learning from your mistakes, stop making them in the first place.
Time to Turn Up the Heat on Your Hot-Runner Maintenance Program
Molders are running more hot-runner manifolds than ever, a trend that’s expected to continue. But once you have them, you need to keep them in shape. Follow these tips to get going.
Breaking Down Hot Runner Maintenance
Improving a manifold’s maintenance plan requires specific skills and knowledge of its functioning areas.
Mold Performance: Tap Into the Power of Data Collection
Collecting core data in a transparent way allows molders to drill into the true cost of tooling issues and develop real goals to keep production flowing.
More Effective Mold Maintenance: It’s All About the Data
When tooling issues are shutting down presses daily and you can’t muster the mold maintenance and operating records to figure out why, then like the song says, “Who ya gonna call?” The answer to that question proved crucial to Cosmetic Specialties International (CSI), LLC in Oxnard, Calif.
Tooling: Setting Up Shop: Part III
Our last column covered shop size and bench requirements for a 50 x 50 ft mold-repair shop that will have a MPP (Mold Pull Pace) of approximately 25 to 30 multi-cavity molds a week and employ four repair technicians in a six-bench layout.
Tooling: Setting Up Shop—Part II of III
Many repair shops in molding facilities are too small, poorly lit, and inefficiently designed.
Tooling: Setting Up a Mold Shop: Part I
I had a toolmaker once tell me he used to slam his hand in his car door before work every morning just to get him in the right frame of mind to work in his shop.
You Think You Know Your Molds? Try These 10 Questions to Find Out for Sure
A mold repair technician’s job has always been to make molds run—anyhow, any way.
Tooling Know-How: Troubleshooting Defects--Part II: Hot-Runner Long Gate Vestiges
Last month, we discussed the general issues of an organized and disciplined process of troubleshooting and correcting mold defects.
Troubleshooting Defects: Part I
Like the three other aspects of a typical mold clean/repair job (disassembly, cleaning, and assembly) there is usually more than one way to skin the cat of troubleshooting and correcting defects.
Enhanced Software for Mold Maintenance
WEB EXCLUSIVE: New versions of two software programs for managing mold maintenance were introduced at the recent NPE show in Chicago by Progressive Components, Wauconda, Ill.
The Eight Stages of Mold Repair
While the mold was still being disassembled, two “cleaners” began pulling tooling out of plates and putting them into buckets in preparation for a good scrubbing—and I mean a scrubbing.
How to Determine Maximum Mold Cycle Counts
At my first production meeting with my new employer, I was told, “We want you to establish a preventive maintenance program that is based on maximum cycle counts for all our molds.” Then, before I could launch into an explanation of how best to determine maximum cycle counts, I was hit with the follow-up: “So, how many cycles do you think our molds can safely run before we need to clean them?”Leaving my crystal ball at home and unable to get my x-ray vision working, there was no way to answer this question with any real accuracy.
Why Not Just Let ’r Leak?
Here’s how a typical West Coast molding facility with 20 injection presses investigated the downtime impact of water leaks in the plant.
What Toolroom Maintenance Supervisors Need to Know-Part II
September’s “Mold Shop” column presented an overview of a mold maintenance supervisor’s need-to-know priorities.
What Toolroom Maintenance Supervisors Need to Know
Those in charge of keeping molds reliable and production-ready normally start their day in the same manner—wondering what broke down since they last walked out the door—and hoping they have the resources to get it going again.
Why Mold-Maintenance Data Is Essential for Processing Technicians
When I was in the Navy, many different trades such as hydraulics, electrical, airframes, armament, and jet-engine mechanics worked side by side to get planes into the air, through their scheduled missions, returned to base, and turned around to do it all over again.
Defect Position Analysis: What It Is, Why You Need It
There are so many new technological options in mold design, moldmaking, and molding today that it boggles the mind: We can simulate melt flows to anticipate difficulties.
