48 Cav Pet Preform Moulding, Injection Molding Systems

Demark pet injection systems offer: 1. Faster cycles(10s) 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.
