Injection molds often trap residual plastic in tight cavities: flash whiskers, burrs, sealed particles, thermal deposits, short shots left in the cavity, or degraded material after downtime. Conventional steel picks can scratch or bruise polished tool steel. MoldPick Copper uses a 100% soft copper working tip that lets you pry, scrape, or push out polymer residue while minimizing the risk of surface damage.
Key Benefits
Precision flat tip – 5 × 10 mm working end shaped like a screwdriver blade; ideal for tight channels, corners, micro pockets; user modifiable (file, grind, shape).
Extended reach – 200 mm overall length accesses deep cores, vents, and multi cavity tooling.
Soft copper contact – gentle on high polish, textured, etched, or coated mold surfaces.
Safe mold service – remove flash, short shots, deposits, and freeze offs around gates.
Hot work capable – can be used on warm/hot tooling (with PPE: heat gloves, insulated grip, short contact cycles).
Technical Data
| Parameter | Value | Notes |
|---|---|---|
| Overall length | 200 mm | Reaches deep cavities / core pockets |
| Working tip size | 5 × 10 mm | Flat screwdriver style; easy to reshape (file / abrasive) |
| Tip material | 100% copper | Non marring on tool steel surfaces |
| Handle material | Anti slip grip (TPR / technical rubber) | Secure hold; thermal buffer; optional full copper handle |
Use Cases
Removing residual thermoplastic from mold cavities.
Prying or lifting trapped short shots / parts from deep recesses.
Scraping light thermal deposits and polymer build up.
Clearing gate freeze offs and hot runner gate obstructions.
Touch up work on high polish and textured mold surfaces.
Quick Use Guide
1. Make safe: confirm operator safe temperature. MoldPick Copper can be used on warm/hot molds with proper PPE.
2. Plan access: align approach to the cavity, core pocket, or gate area.
3. Pry / scrape lightly: use short controlled strokes with the copper tip.
4. Inspect surface: confirm no marking; wipe clean.
5. Reshape tip if needed: file, grind, or stone to match part geometry.
FAQ
1. What is MoldPick Copper used for?
Manual, non marring removal of plastic residue, flash, short shots, and deposits from injection mold cavities.
2. Why copper?
Copper is softer than tool steel, helping prevent scratches on polished or textured surfaces.
3. What are the dimensions?
Overall length: 200 mm. Working tip: 5 × 10 mm flat, screwdriver style; user modifiable.
4. Can I reshape the tip?
Yes. File, grind, narrow, round, or bend the copper to fit your tool geometry.
5. Can I use it on a hot mold?
Yes, for targeted interventions (e.g., blocked hot runner gate) with heat gloves, insulated grip, and short contact time.
6. Is it safe on textured or high polish surfaces?
Yes – designed for sensitive mold finishes.
