450 T Custom Plastic Injection Stretch Moulding Machine Melting Time Less
CWI-450GB, reinforced steel plate and square tube for machine frame Strengthened toggle, bushing and platen tie bars are manufactured from high grade steel. Longer mould opening and ejector stroke and stronger ejection force. Moving platen using lubrication free bushing.
The plasticizing unit has more advantages, adopt high quality material, barrel screw, plastic melting is fast, so reduces melting time.
Injection nozzle and front flange connection design is inside position, result in better connection, hard to leak and can withstand high pressure and high-speed injection.

Advantage of the improved clamping unit and machine structure:
Platen design by finite element analysis to eliminate deformation and fracture and optimise toggle locking system.
Vertical screen can display more data in the main screen simultaneously, different from traditional display
1.process and be freely adjusted to suit different processing needs
2.USB 2.0 interface support for the Ethernet connections, printer and other equipment
3.Eight section of PID control functions, heating each section of the barrel separately, improve plasticisation and prevent overheating
4.Output of the 48 point digital transistor with shot circuit and over load protects function
5.Clamping, injection and ejection strokes are controlled precisely by the linear transducers
6.Automatic mould thickness adjustment -Heating time can be set a week in advance to improve production efficiency
7.Five stages control on mould opening, closing and injection makes the operation more stable and precise
Advantage of computer control unit: Our European computer control unit has high speed CPU and DSP module and it increases high control to analogue output module, back plane module, bus module etc. and has fast response.
