Assawin Siichumphong / Dept. Manager, Design Engineering Dept.

We have a team of engineers dedicated to designing equipment and machinery tailored to our customers' specific needs.

In this department, design engineers use AutoCAD and SOLIDWORKS (3D CAD design software) to create drawings that are subsequently sent to the Manufacturing Department.

▲ The Design Engineering Department is actively engaged in meetings to share information and discuss specifications.

In the design process, we first discuss the concept according to the customer's needs, and then create a drawing.

All members of our team of design engineers are capable of designing special-purpose machinery that meets all of our customers' requirements. You can count on us for complex and highly challenging mechanical designs that other companies may consider too difficult or even impossible.

While standard parts are easy to procure and often meet quality standards from the outset, custom-made parts present greater quality control challenges and may have longer lead times than usual.


Standard parts are identified by their part codes, which makes it easier for customers to procure spare parts.
