Master Your Assembly Line: Choosing the Right

SUMAKE Smart Controller

In today's Industry 4.0 environment, fastening quality is no longer determined solely by torque accuracy. Manufacturers increasingly require complete process visibility, data traceability, and quality assurance throughout the entire assembly process. SUMAKE's Smart Tightening Solution addresses these challenges by combining precision fastening control with advanced data management, helping manufacturers achieve higher productivity and a zero-defect manufacturing strategy.

Precision Control for Every Application

The SUMAKE SMT Controller Series delivers outstanding fastening consistency with a repeatability of 3 Sigma ±5%. Depending on production requirements, different control methods are available:
▪  Torque & Angle Control – Available on SMT-C2 and SMT-C3, providing precise monitoring of both torque and rotational angle for critical fastening applications.
▪  Torque & Thread Control – Available on SMT-C1, enabling monitoring of fastening cycles to verify proper screw seating and tightening completion.

How Torque & Angle Control Prevents Floating Screws and Stripped Threads

Floating Screw (Not Fully Seated)
A screw may reach the target torque before the parts are fully clamped together. By monitoring the rotation angle, the system can detect insufficient screw travel and immediately flag the fastening as abnormal.

Stripped Thread
If the screw continues to rotate but cannot build enough torque, the thread may be damaged. The system detects this condition through excessive angle and insufficient torque, then stops the process and alerts the operator.

More Consistent Clamp Force
Torque alone cannot guarantee a consistent clamping result. By monitoring both torque and angle, the system helps achieve more consistent clamp force from screw to screw, reducing assembly variation and improving product quality.

Simply Put:

▪  Torque confirms the screw is tightened to the correct force.

▪  Angle confirms the screw has reached the correct position.

▪  Torque + Angle helps ensure every screw is tightened in a more consistent and reliable manner.

By combining both measurements, Torque & Angle Control helps prevent floating screws, stripped threads, and other common assembly defects while improving clamp force consistency, product quality, and long-term reliability.
