How To Design A 360L Waste Bin Injection Mould?
1.Structural Design:
Multi-cavity molds with optimized gating systems to ensure uniform wall thickness and minimize defects.
Sliding block mechanisms for undercuts (angle ≤30°) to simplify demolding.
2.Cooling System:
Internal circulating water channels to reduce cooling time by 20–30% and boost production efficiency.
Software: Moldflow analysis for simulating flow balance and detecting potential flaws.
3.Key Equipment:
CNC milling (precision: ±0.1 mm), EDM (±0.1 mm), wire cutting, and surface grinding .
4.Tolerance Control:
Critical dimensions maintained within ±0.1 mm via high-speed milling and precision grinding.
5.Surface Treatment:
Anti-rust coatings and tempering to enhance hardness.

Daily Maintenance Checklist: 360L Plastic Waste Bin Mould
Warranty: 1-year free repair or >1 million-shot lifespan.
Maintenance Tips:
Daily: Lubricate ejector pins, clean mould surfaces.
Periodic: Clear exhaust slots, repair worn parts.
Storage: Apply rust-proofing, seal cavities.
1. Post-Production Cleaning (Every Cycle/Shift):
- Purge all resin residues from cavities, cores, and runners immediately after production.
- Use approved mold cleaners (non-abrasive, non-corrosive) and soft brass/copper brushes.
- Never use steel tools – avoid surface scratches!
2. Ejector System Care:
- Lubricate ejector pins, guide pins, and sleeves daily with high-temperature mold grease.
- Check for smooth movement; binding indicates misalignment or contamination.
3. Cooling Lines Check:
- Inspect water lines/connectors for leaks or blockages.
- Ensure consistent coolant flow – uneven cooling causes warping.
4. Surface Protection:
- Apply a thin layer of rust preventive spray (e.g., silicone-based) on polished surfaces after cleaning.
- Wipe mold faces with a dry, lint-free cloth before storage.
5. Vent & Gas Channel Inspection:
- Clear vents of debris/clogged plastic using a vent cleaner or compressed air (<80 psi).
- Blocked vents cause burns/short shots.
6. Damage Survey:
- Examine cavities, cores, and parting lines for chips, dents, or wear.
- Report defects immediately to avoid costly repairs.
7. Storage Protocol:
- Close and clamp the mould securely when not in use.
- Store in a dry, temperature-controlled area (humidity <50%).
- Cover with breathable fabric to prevent dust accumulation.
