Mastering Extreme Processing
Standard injection molding cannot handle super-polymers. Jucheng provides the specialized infrastructure required for success.
Ultra-High Mold Temperatures
PEEK and PEI require mold temperatures above 160°C. We utilize advanced oil temperature controllers to ensure uniform crystallization and zero internal stress.
In-House Hardened Steel Tooling
Our 25+ 5-axis CNC machines cut mold cores from premium hardened steels (S136, H13) to withstand the high pressures and abrasive nature of high-performance resins.
Zeiss CMM Verification
Critical parts demand certified quality. We use Zeiss CMM inspection to verify every micron, ensuring safety in medical and aerospace applications.
High-Temperature Processing Guidelines
Our high-performance polymer injection molding capabilities focus on materials like PEEK injection molding and Ultem injection molding. These specialty resins are critical for aerospace plastic components and medical grade plastic manufacturing requiring repeated sterilization.
| Polymer Type | Melt Temperature (C) | Mold Temperature (C) | Max Service Temp (C) | Glass Transition (Tg) |
|---|---|---|---|---|
| PEEK (Natural) | 360 - 400 | 160 - 200 | 250 | 143 |
| PEI (Ultem 1000) | 340 - 400 | 130 - 180 | 170 | 217 |
| PPS (40% Glass) | 300 - 340 | 130 - 150 | 200+ | 90 |
| LCP (Liquid Crystal) | 280 - 330 | 80 - 120 | 240 | - |
