Our Process

Here’s a look at our process and how we handle all levels of the development process.


Our first step customers is a consultation to learn more about the hardware needs for the products being developed. With decades of industry experience we are sure to offer input regarding design and construction.

Initial Designs

After our initial consultation we begin developing the initial designs of the hardware. Customers provide us with anything from simple sketches, CAD drawings, or physical samples.

3D Samples

Whether you provide us with physical samples to match, or simple sketches, we use these to develop 3D drawings called STL files. We use these STL files to print plastic samples from our 3D printer in Massachusetts.

Brass & Zinc Samples

After the initial plastic samples are approved we move to brass or zinc sampling. These will be used as the pre-production samples from which the father mold is created.


Once the brass or zinc samples are approved we move to production. Our factory has the capacity to handle both large and small scale production runs.


The hardware is packed and can be delivered anywhere in the world. We also ship ocean containers every 3 weeks from our facility in Asia direct to our Massachusetts warehouse at no cost to you.
