Demark 48 cavities pet preform injection moulding machine@(injection molding machine@injection moulding system@injection molding system@) 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 systems are available from 280 to 500 tonnes (2800 to 5000 kN) and up to 72 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;
Flexible Platens
Flexible platens distribute clamp force evenly across the platen face.
Flexible 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.

Demark Control System
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.

Bronze Self Activated Balancing Valve

Actuated Gate Valve,Pressure Actuated Valve,Pneumatic Actuator Valve,Self Actuated Pressure Control Valve

In the air-conditioning and heating systems, especially in variable flow system, the situation changed when the system is running, the differential pressure of control valve or both ends of terminal equipment will change also.
Once differential pressure was changed too high to precise control will lead to a series of problems: low precision or heavy noise generation in control valve actuation, more serious will cause the control valve cannot be closed, the system function failure even and so on.
