Demark 32 cavities pet preform injection system for pet preform mould,the cooling robot with 3 stations, 10000pcs/h, 2040g, 280T

Demark 32 cavities pet preform injection molding machine uses a new part cooling and handling system, which features:
    1.  Cooling on the inner surface of the preform without using compressed air, unlike most post-mold cooling systems which only cool the outer surface
    2.  Optimized cycle utilization being mounted on the moving platen, the cooling system remains active for up to 85% of the overall cycle.

Demark pet preform injection molding systems are available from 280 to 500 tonnes (2800 to 5000 kN) and up to 96 cavities.
Demark pet injection systems offer:
    1.  Faster cycles
    2.  Reduced energy consumption
    3.  Smaller footprint 
    4.  Improved repeatability 
    5.  Rapid set-up

Features:
    1.  Two state plasticizing enables plenty injection quantity;
    2.  Take out plate with three working position insures sufficient cooling time and shorter cycle time;
    3.  High quality parts and accessories from world famous brands enable higher speed and precision;
    4.  Special screw design increases torque while brings down shear force to avoid degradation;
    5.  Accumulator from world reputable manufacture increases performance while brings down power consumption; Reflex Platens
Reflex platens distribute clamp force evenly across the platen face.
Reflex platens:
    1.  Allow for 10-30% lower clamp tonnage 
    2.  Decrease mold wear 
    3.  Improve part quality 

Injection Units
demark systems offer both reciprocating screw (RS) and two-stage injection units. RS units offer the performance required for many PET applications while two-stage is appropriate for higher throughput applications.
 
Polaris Controls
PC-based controls manage all functions of our PET production systems, with optional packages to integrate auxiliaries and downstream part handling equipment. Advantages include:
    1.  Faster cycle times 
    2.  Improved shot-to-shot repeatability 
    3.  Remote connectivity through ServiceNetLink 
    4.  Control of molding system and auxiliaries from a single interface
 
Linear Bearings
Linear bearings support the moving platen directly on the machine base. This design reduces mold wear by improving platen alignment and perpendicularity, and provides a grease free molding environment.
