Complete Cold Press Machine Engineering Design

MOTORIZED COLD PRESS MACHINE – COMPLETE ENGINEERING DESIGN REQUIREMENT IMPORTANT DESIGN PHILOSOPHY This project is NOT intended to assemble purchased cold press modules. This project is intended to DESIGN, ENGINEER, MACHINE, FABRICATE, ASSEMBLE and COMMISSION a complete industrial cold press machine from raw materials and standard industrial components. Every fabricated component must be designed. Every machined component must be dimensioned. Every assembly must have exploded drawings. Every mechanism must be fully explained. Every subsystem must be fabrication-ready. No black-box assemblies. No purchased press structure. No purchased screw lift assemblies. No purchased platen systems. All major systems must be engineered. --- MACHINE TYPE Industrial Motorized Cold Press Applications: • Laminate Pressing • Plywood Pressing • Veneer Pressing • Decorative Sheet Bonding • Furniture Panel Manufacturing • Composite Panel Pressing --- CAPACITY Panel Size: 2440 × 1220 mm (8×4) Bed Size: 2550 × 1300 mm Stack Capacity: 20 Sheets Minimum Daylight Opening: 600 mm Press Force: Calculate and optimize for laminate pressing and furniture panel manufacturing. --- DESIGN DELIVERABLE REQUIREMENT Provide complete: A.
