Production Capacity of Various Window Fabrication Equipment
Equipment Capacity Calculation (Based on 1,000㎡ Daily Output of Doors & Windows)
(1) Single Equipment Capacity Reference (8-Hour Workday)
Equipment Type | Single Unit Capacity (㎡/Day) | Notes |
CNC Double-Head Precision Cutting Saw | 300-400 | Higher efficiency for aluminum profiles than plastic profiles |
Four-Station UPVC Profile Welding Machine | 200-250 | Only for upvc doors/windows |
Automatic Insulated Glass Production Line | 500-600 | Including cleaning, lamination, gluing and full process |
CNC Corner Crimping Machine | 350-450 | Core equipment for aluminum door/window corner assembly |
Automatic Gluing Machine | 400-500 | 3x more efficient than manual gluing |
(2) Equipment Quantity Configuration (Matching 1,000㎡ Daily Output)
• Raw Material Processing: 3 set of CNC double-head precision cutting saws (2 for aluminum profiles + 1 for UPVC profiles), 2 sets of profile end milling machines, 1 set of knurling and strip feeding production line, 4 sets of four-station welding machines (increase if UPVC doors/windows account for a high proportion).
• Glass Processing: 1 set of automatic glass cutting machine, 2 sets of insulated glass production lines, 1 set of glass edging machine, 1 set of drilling machine.
• Assembly & Inspection: 3 sets of CNC corner crimping machines, 2 sets of automatic gluing machines, 8-10 assembly workbenches (zoned operation), 1 set of physical performance testing machine (for random inspection).
Staffing Configuration (Divided by Process, Including Management & Support Personnel)
(1) Core Production Process Staff (Based on 1,000㎡ Daily Output)
Process | Job Description | Staff Quantity | Skill Requirements |
Raw Material Cutting | Operating cutting saws and end milling machines; profile blanking | 6-8 people | Familiar with CNC equipment operation; proficient in profile dimension conversion |
Profile Processing (Strip knurling and feeding/UPVC Welding) | Broken-bridge aluminum assembly machine; upvc profile welding | 4-6 people | Master strip feeding and pressing technology or welding parameter adjustment |
Glass Processing | Glass cutting, edging, and insulated glass assembly | 8-10 people | Understand glass dimension precision requirements; familiar with insulated glass line operation |
Hardware Assembly | Hardware installation and screw fastening | 10-12 people | Familiar with different door/window hardware configurations; strong practical ability |
Door & Window Assembly | Profile splicing, corner crimping, and gluing | 12-15 people | Master corner crimping technology and sealant application skills |
Finished Product Inspection | Testing air tightness, water tightness, etc. | 3-4 people | Understand national standard testing criteria; proficient in operating testing equipment |
(2) Support & Management Positions
• Raw Material/Finished Product Warehousing: 4-5 people (responsible for warehousing, inventory of profiles, glass, hardware, and finished product delivery).
• Equipment Maintenance: 3-4 people (responsible for daily equipment maintenance and troubleshooting to ensure equipment operation rate ≥95%).
• Quality Inspection: 2-3 people (random inspection of semi-finished products in each process to prevent defective products from flowing to the next process).
• Management Positions: 1 Production Supervisor, 2 Process Technicians, 1 Dispatcher.
(3) Total Staffing
• Core Production Workers: 50-60 people (balanced allocation by process to avoid bottlenecks).
• Support & Management: 13-16 people.
• Total Employees: 63-76 people (adjustable based on automation level; higher automation reduces staffing by 10%-15%).
IV. Scheme Optimization Suggestions
1. Automation Upgrade: Large-scale door and window factories are advised to gradually introduce intelligent production lines (e.g., automatic profile loading, automatic glass transfer, automatic finished product palletizing), which can reduce labor costs by over 30% in the long run and improve product consistency.
2. Flexible Capacity Adjustment: To expand capacity, prioritize adding core bottleneck equipment (e.g., insulated glass production lines, corner crimping machines) instead of blindly increasing staff to avoid labor redundancy.
3. Personnel Training: Focus on training CNC equipment operators and inspectors to maximize equipment capacity and reduce defective product rate (target: ≤1%).
4. Equipment Maintenance: Establish a regular equipment maintenance system; conduct weekly maintenance on core processing equipment (e.g., cutting saws, corner crimping machines) to extend equipment service life and reduce maintenance costs.
