Double Mitre Saw

The double mitre saw is one of the most important machines in every fabrication workshop.

It cuts window profiles accurately at various angles, typically 45° and 90°.

Advantages include:

• High cutting accuracy
• Smooth surfaces
• Fast production
• Reduced waste

It is used for both aluminium and uPVC profile cutting.

---

CNC Machining Center

Modern CNC machining centers automate many fabrication processes.

Typical operations include:

• Lock openings
• Handle holes
• Drainage slots
• Hardware pockets
• Hinge drilling
• Connector preparation

Benefits include:

• High precision
• Repeatability
• Reduced manual work
• Faster production

CNC technology is now standard in professional window manufacturing.

---

End Milling Machine

End milling machines prepare profile ends before assembly.

They are mainly used for:

• Mullions
• Transoms
• Frame connectors
• Structural joints

Accurate end milling improves assembly quality and structural strength.

---

Corner Crimping Machine

Used primarily for aluminium windows.

The machine permanently joins mitred aluminium corners using corner cleats and hydraulic pressure.

Benefits include:

• Strong corner joints

• Consistent quality

---

Corner Welding Machine

Exclusive to uPVC manufacturing.

Profile corners are heated and fused together under pressure.

Advantages include:

• Permanent joints
• Excellent sealing
• High structural strength
• Smooth appearance

Automatic four-head welding machines significantly improve production efficiency.

---

Corner Cleaning Machine

After welding, excess material must be removed.

Corner cleaning machines:

• Remove weld beads
• Smooth profile surfaces
• Prepare frames for hardware installation
• Improve appearance

Most modern systems are fully CNC controlled.

---

Copy Router Machine

A copy router is used for precision routing operations.

Typical applications include:

• Handle holes
• Lock openings
• Ventilation slots
• Drainage channels

Although CNC machining centers can perform many of these tasks, copy routers remain popular for smaller workshops.

---

Profile Punching Machine

Punching machines quickly create standardized openings in aluminium profiles.

They are commonly used for:

• Hardware fixing points
• Drainage holes
• Connection slots
• Assembly holes

Mechanical punching increases productivity.

---

Glazing Bead Saw

Glazing bead saws cut glazing beads to precise lengths.

Accurate bead cutting ensures:

• Better glass retention
• Improved appearance
• Faster installation

---

Glass Handling Equipment

Modern factories often use specialized equipment for insulated glass handling.

Examples include:

• Vacuum lifters
• Glass transport tables
• Glass storage racks
• Automatic glazing stations

These systems improve safety while reducing glass damage.

---

Assembly Tables

Assembly tables provide a flat, stable workspace.

Many include:

• Adjustable supports
• Pneumatic clamps
• Measuring systems
• Roller conveyors

They improve assembly accuracy and worker efficiency.

---

Hardware Installation Stations

Dedicated workstations simplify the installation of:

• Hinges
• Locks
• Handles
• Rollers
• Restrictors
• Multi-point locking systems

Proper installation ensures smooth operation and long service life.

---

Quality Control Equipment

Every finished window should undergo inspection.

Quality control may include:

• Dimension verification
• Corner strength testing
• Hardware testing
• Water tightness tests
• Air permeability tests
• Surface inspection
• Glass inspection

Consistent quality control reduces customer complaints and warranty issues.

---

Factory Automation

Modern window factories increasingly use automation technologies.

Examples include:

• Barcode tracking
• Production management software
• CNC integration
• Automatic conveyors
• Robotic profile handling
• Digital production planning

Automation improves productivity while reducing errors.

---

Choosing the Right Machines

The ideal equipment depends on:

• Production volume
• Window material
• Available space
• Budget
• Automation level
• Workforce experience
• Product range

Small workshops may begin with manual or semi-automatic equipment, while large manufacturers often invest in fully automated production lines.
