ECO line series is Economy pet preform line. With or without The Take-out Robot with 3 Station Cooling ,Only 10S.
Demark 24,32,48cavities pet preform plant 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 24 to 48 cavities pet preform mould.
Demark pet injection systems offer:
1. Faster cycles(10S)
2. Reduced energy consumption
3. Smaller footprint
4. Improved repeatability
5. Rapid set-up
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
Controls
DMK-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.
