Clamping Unit

1. Highly accurate and rigid nodular graphite casting steel platens designed through CAE finite element analysis ensure optimal requirement of clamping
2. Five-point vertical double toggles and chrome-plated high tensile tie-bars give stable platen movement and sufficient clamping force
3. Clamping speed is largely increased over 80% by adopting differential hydraulic circuit
4. Extended daylight opening and enlarged platens allow accommodation of bigger moulds
5. Electrical, hydraulic and mechanical safety devices are all employed to ensure safe operation
6. Hydraulic ejector is enhanced with selectable modes of non-return, vibration or multi-stroke
7. Prompt and accurate change of every closing/opening stage ensures smooth mould travelling and mould protection
8. The application of self-lubricating bushings in platens, cylinder rods, guide rods, etc. can largely eliminate wear of mechanical parts and thus prolong machine life

Injection Unit

1. Nitrided screw and barrel
2. Productivity can be increased by high speed and high pressure injection and plasticizing
3. Screw with L/D ratio 20:1 suits moulding most engineering resins
4. Automatic screw purging and nozzle hunting
5. Double hydraulic carriage cylinders ensure secured contact between nozzle and mould and prevent nozzle leakage
6. The design and T-shape slide-way for movement of injection unit results in highly stable operation
7. Plasticizing back pressure control
8. Swivel-mounted carriage unit can ease the maintenance of screw and barrel
9. Special design of screw check valve allows the best plasticizing result in both mixing and melting

T-6 Controller

1. Specially designed computerized controller Techtronic T-6 shows all operation parameters and allows memory storage of 200 moulding data sets. It also gives warning messages in case of malfunction
2. 7 inches 16:9 color LCD monitor with Chinese/English character interchangeable display
3. Direct input of pressure, speed, position, time, moulding temperature and functions
4. 6-stage setting for injection pressure, speed and position
5. 4-stage setting for injection holding pressure, speed and time
6. 3-stage setting for plasticizing pressure, speed and position
7. 5-stage setting for mould close and 4-stage setting for mould open pressure, speed and position
8. 2-stage setting for ejection pressure, speed and position
9. Highly accurate potentiometers monitor mould, screw and ejector positions
10. Injection volume detection and screw prevention of cold start
11. Built-in PID temperature control program and solid state relays in heater circuit give accurate moulding temperature and durable control circuit
12. Independent heater temperature malfunction monitoring device to prevent barrel overheat.
13. Safety protection monitoring prevents malfunctional mould closing.
14. Control for accumulator, automatic dual core pulling, unscrewing device, dual air ejectors, photo-cell detector and extractor, etc.
15. Pre-setting product count.
16. Injection and mould data can be saved in computer or SD memory card.
17. Optional application of INET Network through internet remotely monitors production activities.
18. Multi-stage password protection, prevent data to be mistakenly changed easily.

Hydraulic Control

1. High pressure and high speed performance can be achieved by employing large displacement pump driven by high power electric motor
2. Use of imported brands hydraulic valves ensures highly precise moulding
3. Hydraulic blocks are mounted close to the actuators to reduce discrepancy
4. All-time hydraulic oil filtering (only used with variable displacement pump)
