View DetailsDTPPN vs DTNK: Which Tool Do You Need?
Two tools for two different date mark pin types — make sure you have the right one:
| Feature | DTPPN Screwdriver | DTNK Removal Jig |
|---|---|---|
| Function | Rotate date ring position | Extract pin from mold bore |
| Compatible With | All standard date mark pin sets (PL, Plate, Double Ring, Adjustable) | Heat-resistant pins with removable tap ONLY |
| Mechanism | Pointed tip engages pin groove | Threaded engagement into tap hole |
| Use Frequency | Monthly (date rotation) | As needed (pin extraction for maintenance) |
| Cost | $ | $$ |
Decision rule: DTPPN is for push-type extraction (PL-side pins). DTNK is for pull-type extraction (plate-side pins). Using the wrong tool damages the insert. For the full compatibility chart, see our DTPPN vs. DTNK Tool Comparison.
Tool Compatibility Chart
Which tool works with which date mark pin type:

| PL-Side Exchange (Tapered/Convex) | ✓ Compatible | ✗ Not compatible |
| Plate-Side Exchange (All types) | ✓ Compatible | ✗ Not compatible |
| Double Ring | ✓ Compatible | ✗ Not compatible |
| L Adjustable | ✓ Compatible | ✗ Not compatible |
| Heat-Resistant (Removable Tap) | ✓ For rotation | ✓ For extraction |
Application Scenarios
See how these products solve real engineering challenges across industries:
Scheduled Mold Maintenance Operations
Monthly date code changes across 20+ molds require fast, damage-free pin rotation. The DTPPN screwdriver engages standard pins in seconds, while the DTNK jig threads into heat-resistant removal taps.
Why it fits: The DTPPN screwdriver features a precision-machined tip that engages the pin head slot without slippage. The DTNK jig threads directly into the removal tap on heat-resistant pins, applying controlled axial pull force. Both tools prevent the cross-threading and head marring caused by improvised screwdrivers and pliers.
Quick-Change Production Environments
Just-in-time manufacturing with daily date changes cannot afford pin damage from improvised tools. Purpose-built removal tools prevent cross-threading and pin head marring that cause premature replacement.
Why it fits: Purpose-built removal tools reduce date change time from 3–5 minutes (improvised tools) to under 1 minute per cavity. Over 20+ molds with monthly changes, this saves 80–160 minutes of press downtime per month — equivalent to 2–4 additional production runs.
