1. مقدمة في صب الراتنج
صب الراتنج هو تقنية متعددة الاستخدامات تستخدم للإنشاء مفصل, دائم, ولامع الكائنات, من المجوهرات والتماثيل إلى الأجزاء الوظيفية والقطع الفنية. تتضمن العملية صب الراتنج السائل في قالب, السماح لها بالشفاء, وإزالة القوالب من المنتج النهائي.
التطبيقات الرئيسية:
- صناعة المجوهرات (المعلقات, حلق, اقراط)
- المنمنمات & التماثيل (ألعاب منضدية, هواتف محموله)
- الأجزاء الوظيفية (أغطية المفاتيح, المقابض, النماذج)
- فن & ديكور (طاولات النهر, الجيودس, أوزان الورق)
2. أنواع الراتنج للصب
| نوع الراتنج | وقت العلاج | ملامح | أفضل ل |
|---|---|---|---|
| راتنجات الايبوكسي | 24-72 ساعة | وضوح عالي, مقاومة للأشعة فوق البنفسجية, التسوية الذاتية | المجوهرات, أجهزة الكمبيوتر اللوحية, يصب عميق |
| راتنج البولي يوريثين | 10-30 دقيقة | علاج سريع, دائم, slightly flexible | Rapid prototyping, industrial parts |
| UV Resin | 1–5 min (UV light) | Instant cure, no mixing needed | Small jewelry, quick fixes |
| Polyester Resin | 30–60 min | Strong, brittle, strong odor | Large sculptures, fiberglass work |
Safety Note: Always work in a well-ventilated area and wear gloves, goggles, and a respirator when handling resin.
3. Essential Tools & Materials
Basic Supplies:
✅ راتينج & Hardener (correct ratio is critical)
✅ Silicone Molds (food-grade for flexibility)
✅ Mixing Cups & Sticks (graduated cups for precise ratios)
✅ Isopropyl Alcohol (IPA) (for cleaning bubbles)
✅ Heat Gun or Torch (for bubble removal)
✅ Release Agent (for easy demolding)
Advanced Tools (Optional):
? Pressure Pot/Vacuum Chamber (eliminates bubbles)
? Digital Scale (for precise resin mixing)
? Pigments & Glitters (for coloring effects)
4. Step-by-Step Resin Casting Process
Step 1: Prepare the Mold
- Clean the mold (dust-free) and apply mold release spray if needed.
- Secure the mold on a level surface (prevents uneven curing).
Step 2: Mix the Resin
- Measure راتينج & hardener by weight/volume (follow manufacturer’s ratio).
- Stir slowly for 2–3 minutes (avoid whipping to reduce bubbles).
Step 3: Add Color & Effects (Optional)
- Mix in alcohol inks, mica powders, or glow pigments.
- Layer different colors for geode or ocean effects.
Step 4: Pour the Resin
- Pour slowly in a thin stream to minimize bubbles.
- For deep molds, pour in layers (cure 2–3 hrs between layers).
Step 5: Remove Bubbles
- Heat Gun/Torch: Pass lightly over the surface to pop bubbles.
- Toothpick/Needle: Manually pop stubborn bubbles.
- Pressure Pot (Best): 40–60 PSI for 30 min eliminates nearly all bubbles.
Step 6: Cure & Demold
- وقت العلاج: 24-72 ساعة (depends on resin type).
- Demolding: Gently flex the silicone mold to release the piece.
Step 7: Post-Processing
- Sanding: Use wet sanding (400–3000 grit) for a smooth finish.
- Polishing: Buff with resin polish or UV top coat for shine.
5. Troubleshooting Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Sticky/Tacky Resin | Incorrect ratio, cold temps | Re-mix properly, warm resin before use |
| Bubbles in Casting | Fast pouring, no degassing | Use a pressure pot, pour slower |
| Resin Won’t Harden | Old resin, wrong ratio | Check expiration date, remix |
| Cloudy Finish | Moisture contamination, poor sanding | Seal with clear coat, polish |
6. Advanced Techniques
A. Embedding Objects
- Flowers, beads, or metal leaf can be suspended in resin.
- Tip: Seal organic materials (e.g., dried flowers) to prevent discoloration.
B. Creating “Fake” Geodes
- Layer crushed glass, metallic pigments, and clear resin for a crystal effect.
C. Two-Part Molds for 3D Objects
- Use silicone putty to capture complex shapes (e.g., figurines).
7. Safety & Best Practices
⚠️ Work in a ventilated space (resin fumes can be toxic).
⚠️ Wear PPE (nitrile gloves, goggles, respirator).
⚠️ Dispose of waste properly (uncured resin is hazardous).
