48 cav Pet Preform Injection Molding Machine

Demark 48 cavities pet preform injection molding system@(injection moulding system@injection moulding machine@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 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; 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.
