表格
| Type | Heat‑transfer Medium | Operating Temperature Range | Main Features |
|---|---|---|---|
| Water‑type Mold Temperature Controller | Clean water | Ambient ~ 180 °C | High heat‑conductivity, low cost, clean & eco‑friendly. Sealed pressurized system is required above 100 °C to avoid medium vaporization. Suitable for general‑grade plastics such as PP, ABS and nylon. |
| Oil‑type Mold Temperature Controller | Thermal‑conducting oil | 180 °C ~ above 300 °C | Achieves high operating temperature with good thermal stability. Lower thermal efficiency compared with water; thermal oil needs periodic replacement leading to slightly higher running cost. Suitable for high‑performance engineering plastics e.g. PEEK, LCP and special processes. |
Detailed Core Technical Specifications
Temperature Control Accuracy: Key performance indicator. Ordinary meter‑controlled models reach ±1 °C. Micro‑computer PID controlled units achieve ±0.5 °C or better, ideal for high‑precision products sensitive to temperature fluctuation.
Heating Power (kW): Determines heating capacity and heating‑up speed. Higher power shortens time to reach target mold temperature. ‑ Small injection‑molding machine (＜100 t): 6 kW‑9 kW ‑ Medium injection‑molding machine (150‑500 t): 9 kW‑12 kW ‑ Large injection‑molding machine (＞500 t): ≥15 kW, up to 60 kW for heavy‑duty applications.
Pump Parameters (Power / Flow / Pressure): Pump serves as the heart for circulating medium to all mold cooling channels and guarantees uniform temperature distribution. ‑ Pump power: HP or kW (0.5 HP, 1 HP, 2 HP etc.) ‑ Flow rate (L/min): Higher flow enables sufficient heat exchange. ‑ Pressure (bar / m head): Overcomes resistance of complex narrow‑long mold channels; high‑pressure pump required for intricate mold waterways.
Cooling Mode ‑ Direct cooling: Low‑temperature cooling‑tower water is injected directly into circulation loop. Fast cooling speed, high water‑quality requirement; widely used for water‑type units. ‑ Indirect cooling: Heat exchanged via heat‑exchanger between process medium and cooling water without medium mixing. Slightly slower cooling; prevents contamination & corrosion; standard configuration for oil‑type and high‑temperature water‑type machines.
Circuit Configuration ‑ Single‑circuit: One temperature zone for most conventional molds. ‑ Dual‑circuit / Multi‑circuit: Independent heating & circulation loops. Supplies different set‑points for moving half / fixed half of one mold, or serves multiple molds simultaneously for sophisticated molding processes.
Selection Guidelines
- Select unit type according to target temperature: Water‑type is cost‑effective below 120 °C. Oil‑type is preferred for process temperature above 120‑150 °C.
- Determine heating power referencing injection‑machine tonnage.
- Match pump performance to mold waterway geometry: Simple large‑size channels emphasize high flow; narrow‑long complex channels emphasize high pump head. Provide mold waterway information to supplier for accurate selection.
- Verify safety functions: Confirm low‑medium‑level, over‑temperature and overload alarm plus power‑supply protection. Prefer micro‑computer PID models for high‑precision requirements.
