DMK-PET72B plastic injection machine

Injection Machines for 72 Cavities Pet Preform Mould Injection machine Plastic Injection machine Preform Injection machine Demark72 cavities pet preform injection moldingmachineusesa new part cooling and handling system, whichfeatures: 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. Optimizedcycle utilization being mounted onthe moving platen, the cooling system remainsactive for up to 85% of the overall cycle. Demark pet preform injection molding systems are available from280 to 500 tonnes (2800 to 5000 kN) andup to72 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.
