Case Study: TRANSITIONING TO CONTROLLED SCREW SEQUENCING IN SE ASIA’S HI-FI SECTOR

How a High-End Audio Manufacturer in Malaysia Reduced Assembly Errors by 80% Using Controlled Auto Screw Feeding

Customer Context 

• Industry: High-End Audio Equipment Manufacturing 
  
• Location: Ipoh, Malaysia
  
• Application: Manual screw fastening in final assembly
• Production Type: Precision audio systems

The manufacturer produces premium audio equipment where mechanical precision and cosmetic quality are critical.

The Operational Bottleneck

Manual screw fastening presented several operational risks: 

• Risk of dropping screw bits (tooling fall hazard)
• Operator fastening in incorrect sequence
• Inconsistent screw angle during insertion
• Over-torque or under-torque conditions
• Assembly errors due to human variability

For high-end audio products, incorrect torque or misalignment can affect: 

• Mechanical integrity
• Cosmetic finish
• Acoustic stability
• Brand perception

The Requirement:  

Reduce human error while improving cycle time and fastening consistency.

Solution Architecture 

Toki implemented an auto-feeding screw system with process control integration.

Key features deployed:

• Automatic screw bit feeding to eliminate drop risk  
• Torque-controlled fastening with digital meter
• Tilting angle monitoring and control
• Pre-programmed screw sequence control
• Controlled screwing order to standardize assembly
  

This converted a variable manual process into a controlled fastening system.

Results 

Post-implementation performance improvements:

• 80% reduction in assembly errors
• 15–20% reduction in cycle time
• Improved torque consistency
• Reduced rework and adjustment
• Increased assembly standardisation

Operators no longer needed to manually pick or align screw bits, reducing handling time and error exposure.

Strategic Impact

1. Quality Protection 

Consistent torque and angle control reduced risk of misalignment and cosmetic damage. 

2. Error-Proofing

Automated feed and sequence control minimized human error variability. 

3. Productivity Improvement

Cycle time reduction improved throughput without increasing manpower.

4. Brand Safeguarding

For premium audio equipment, mechanical precision directly supports product positioning.
