Key FactorsConventional Applications Thinwall Applications
| Typical wall | 2.0 – 3.0 mm | 1.2 -2.0 mm | less than 1.2 mm | ||||||
| Machinery | Standard | High-end | Customized high-end | ||||||
| Inj. pressures | 9,000 – 14,000 psi | 16,000 – 20,000 psi | 20,000 – 35,000 psi | ||||||
| Hydraulic system | Standard | Standard | Accumulators, servo valves | ||||||
| Time to fill | less than 2 sec | 1 to 2 sec | 0.1 to 1 sec | ||||||
| Cycle time | 40 – 60 sec | 20 – 40 sec | 6 – 20 sec | ||||||
| Tooling | Standard | Better venting, | Extreme venting, mold interlocks, | more ejector pins, | precise mold surface prep., | better polish | extensive ejection features, | mold costs 30 – 40% higher | vs. standard |
