  Excellent productivity
 
It realizes the maximized sewing speed of 2.500SPM, and thoroughly studies and analyzes all the sewing-related operation mechanisms regarding X-Y feed, thread trimming, wiper, and pressing plate to bring the best productivity to the work site. And the provision of the sewing range of 50mm × 40mm, the widest range among the similar models, enables a wide range of tasks.
  Various patterns
 
This series provides 56 types of basic patterns with diverse sizes and stitch lengths according to diverse purposes, and shows the prompt and powerful function in any sewing project.
 
  Stable and elegant sewing
 






The sewing stability is brought by adopting the sewing mechanism to extend the sewing range in order to perform the fine stitch under the diverse work environments, and mounting the high-reliable shuttle hook.
The SunStar's control technology-intensive X-Y feed control system is controlled in a smooth and accurate way to show the best performance in the difficult oblique line and curved sewing project.

 
  Best workability
 

This series realizes the optimal work range of 50mm(X) × 40mm(Y) for the shaped needle, labeling task, part task, and supplementary needle.
 
  Pivotal Motor (directly attached)
 
















Through the application of directly attached motor driven method, excellent responsibility and comfortable working environment is provided.

SunStar newly developed the direct driven-motor, which is directly attached to the sewing machine. It is optimized into the high quality sewing process by the use of the coupling method to link AC Sub Motor to the upper level to enhance the responsibility and accuracy of stopping location of the sewing machine.

Since the directly driven motor doesn't use V-belt, the noise and vibration is significantly decreased to provide the pleasant working environment and the fatigue of a site-worker was decreased to help enhance productivity.

In addition to that, as there is no weight-load found when the V-belt is operated, the durability of the machine is considerably increased, and the amount of electricity power consumption was decreased since the rotation loss disappears resulting from the V-belt usage. Since the motor is directly attached to the body of sewing machine, it brings easier access to the installation process by removing the need for attaching and adjusting the sewing machine motor and V-belt. And sewing machine motor and V-belt are not exposed to the worker to prevent the safety accidents in the work-sites.
 
  Operation box
 




Our fullest effort was made for the worker's convenience and increase of productivity by enabling the operation box to be attached anywhere into the upper table or lower table

For the operation box, various function such as pattern change, speed adjustment, zoom-in, zoom-out, and bobbin counter setting are represented through icons for the operation box, and all such functions can be set by one-touch mode. And seven patterns are saved through three function keys to realize the prompt task and cycle task with the combination of various patterns.
 
  Electronic wiper device
 





The electronic solenoid driven-wiper a device to elaborate the sewing fabric for the next task. And you can easily select on/off option by selecting the parameter.

 
  Upper thread holding device (optional)
 






Since the remaining amount of upper thread needed for the first stitching after thread trimming is consistently maintained regardless of the thread type, the first stitching has its own stability to reduce defective rate and increase the productivity.


 
 
 






Since the presser foot can be basically raised up to a maximum height of 20MM, it shows the excellent performance in the pattern task or bar-tacking task regardless of the fabric type.



 
 
 






The right and left presser feet are designed to separately operate to bring the convenience of location control when the fabric is fed. And the simple process of parameter selection makes it possible to easily change the operation sequence of both feed plates and freely change into the integrated driving mode. It maximizes the user's applicability.
