Scientific Molding
Why GW/SM™ (Scientific Molding)?
- GW/SM™ techniques ensure high quality, repeatable production
- Consistently mold quality parts despite variation in molding materials and processing equipment
- Includes rigorous statistical qualifications
- Development of robust processes regardless of manufacturing location
- Can be used on all molds (new and transfer)
- Mold-specific process development (rather than machine-specific)
- Improved time-to-market and component quality
Critical Steps to Scientific Molding:
- Mechanical cycling
- Short shot analysis and fill study
- Viscosity curve and gate freeze
- Balance of fill between cavities
- Pressure loss through system
- Quality inspection and critical dimension review
- High/low challenge
- Weight study
- Document process sheet
- Cavity pressure transducers – pressure versus time curves
