ALLJACK Main Office

At ALLJACK our customers are our top priority.  It is our mission to deliver products that exceed expectation while maintaining the security and confidentiality necessary in the competitive marketplace.  Our extensive employee training and multi-tiered quality control system ensure that nothing leaves our factory short of perfect. Our relationship with our customers doesn’t end once we ship the finished product.  We are here to be your partners in design and manufacturing now and for years to come.

A Message from the CEO & Founder

In 1984, as an apprentice model-maker, I entered the exciting field of Research and Development.  In 1997, after years of perfecting my craft, I founded ALLJACK to serve ID & ME designers worldwide.  Since then I have traveled the map extensively, developing a global vision for the company in terms of aesthetics, regional nuances, and culturally-appropriate design.

I firmly believe that you are never done learning and I enjoy taking an active role in discussions with designers.  Tastes and design preferences vary from region to region, and advancements in technology keep us all on our toes.  Studying new techniques and learning about new industries are personal hobbies of mine.

20 years later ALLJACK continues to evolve, offering mass-production services globally while maintaining the close, personal relationship with our customers that brought us so much success as leaders in prototyping.  Today ALLJACK is, without a doubt, the design industry’s best partner for the future.  We welcome designers from the world over to visit with us and see our state-of-the-art manufacturing capabilities.


-Simon Duh, Founder & CEO


From the beginning, we have always held ourselves to the highest standard as corporate citizens.  We prioritize our contributions to society while simultaneously pursuing corporate growth and sustainable product development.  We pride ourselves on the quality of the product we deliver, our customer service, and the skill of our team members.


ALLJACK was founded in 1997 by Simon Duh, an engineer dedicated to quality manufacturing and artistry since 1984.  Since then ALLJACK has grown exponentially – what began as a small prototyping shop in Taipei has become an international powerhouse.  20 years later ALLJACK has global reach with several factories, and sales offices in Taiwan, Japan, and California.

Today, with the same focus and attention that established ALLJACK as an industry leader in prototyping, the company provides mass-production services for customers worldwide.  We know that our growth and success is made possible by the relationships we share with our customers, our partners in the industry.  It is our privilege to offer unparalleled levels of service, security, and quality for all your manufacturing needs.
