| Aspect | Thread Molding Molds | High-Clarity Molds |
|---|---|---|
| Primary Purpose | Producing threaded parts (bottle caps, screws) | Manufacturing optical-grade transparent parts (lenses, light guides) |
| Key Technology | Rotating cores/collapsible mechanisms | Mirror polishing + conformal cooling |
| Mold Structure | Complex rotating/ejecting systems | Ultra-smooth cavities + special coatings |
| Material | Wear-resistant steel (e.g., H13) | High-polish stainless (e.g., S136H) |
| Machine Needs | High-torque drive systems | Precision temperature control |
| Typical Products | Closures, connectors, fasteners | Optical components, transparent pac |
Higher efficiency: Eliminates secondary threading operations
Stronger threads: No cutting stress compared to machined threads
Cost-effective: Lower per-unit cost for mass production
Higher tooling cost: Complex rotating mechanisms required
Design limitations: Deep threads or special profiles challenging
Maintenance intensive: Moving parts prone to wear
Optical quality: >90% light transmission, <1% haze
Flawless surfaces: Minimizes flow marks and defects
Premium applications: Medical and optical industries
Extremely high cost: Mirror polishing and coatings expensive
Stringent requirements: Cleanroom environment needed
Yield challenges: Minor defects cause rejection
| Application Need | Recommended Solution |
|---|---|
| Threaded components | Thread molding |
| Optical-quality transparency | High-clarity mold |
| Combined needs (e.g., premium cosmetic packaging) | Hybrid solution (high cost) |
Thread molding excels for mass-produced threaded components
High-clarity molds deliver optical perfection at premium cost
Hybrid solutions exist but significantly increase complexity
Recommendations:
Base selection on primary product requirements
Consider production volumes (high-clarity often for lower volumes)
Partner with specialized mold makers for optimal results
