What To Do If Your Cold-pressed Needle Crimping Device Rusts? Here Are Some Maintenance Tips

When you're messing around with strong and weak current wiring, if you don't maintain your contact crimper device properly, spots of rust will appear on its surface in just a few months. Many people think this is just a cosmetic issue, but rust directly increases friction on the jaws, leading to improper crimping or damage to terminals. Today, let's talk about how to properly prevent rust and extend the life of your tools.

Why does your cold-press crimping tool always get moldy?

Many people simply toss their d sub contact crimper crimping tool into a damp tool bag after finishing work, or wipe their sweaty hands directly onto metal parts without wiping. Once the metal surface comes into contact with moisture and salt in the air, an oxidation reaction begins. Especially for pliers that haven't undergone special surface treatment, the rusting speed is alarmingly fast. Poor storage conditions are the main cause, and not lubricating them for a long time is also a major problem.

Condensation caused by environmental temperature differences

In basements or construction sites with large temperature differences between day and night, tiny water droplets easily form on the surface of metal tools. The condensate seeped into the gaps between the precision gears and springs of the contact crimping, corroding them from the inside. By the time it was discovered, the gears were no longer rotating smoothly.

This simple rust-prevention technique can make a cold-pressed needle crimping tool look brand new.

The most direct way to prevent rust is through physical isolation. Spending an extra 30 seconds before finishing work each day is far more effective than spending hours on rust removal later.

Apply an oil film

Take a clean cotton cloth and apply two drops of sewing machine oil or WD-40. Evenly coat the metal parts of the cold-pressed needle crimping tool. Don't apply too thickly; a thin layer of shine is sufficient. The oil film acts like plastic wrap, keeping moisture out. If you find aluminum or copper shavings in the jaws, remember to clean them with an old toothbrush before applying oil.

Pay special attention to the moving pins:

The biggest problem with cold-pressed needle crimping tools is jamming at the joints. Spray a penetrating lubricant at the lever fulcrum and spring positions. Knead repeatedly a few times to allow the lubricant to penetrate. Regular maintenance like this keeps the handle's rebound force feeling as crisp as when it was new.

Storage Tips: Don't let the environment ruin your good tool.

Rust prevention isn't just about oiling; how you store it is also important.

• Desiccants are a great help: Just throw a few packets of desiccant from food packaging into your toolbox—the cost is practically zero.

• Don't store with corrosive substances: Acidic fumes from lead-acid batteries or cleaning agents are the enemy of cold-press crimping needles.

• The resealable bag method: If you're not going to use this cold-pressing needle crimping needle in the near future, it's recommended to apply oil, put it in a resealable bag, remove the air, and then store it.
