FAQs

We manufacture custom metal and plastic parts from bar or tube stock to the highest standards of quality and precision. We also provide CNC turning and milling, sheet metal fabrication, and injection molding.

Our CNC machining operations are certified under ISO 9001:2015 as verified by SGS, ensuring we adhere to globally recognized quality management standards. This certification confirms our commitment to consistently providing high-quality products and services that meet customer and regulatory requirements.

We are involved with almost every industry imaginable. We serve aerospace, energy, medical, dental, automotive and many others.

Unfortunately, we now only accept wire transfers and PayPal. If you have any questions about payment methods, please feel free to contact our support team.

We offer design services to our clients, but it’s important to note that we don’t provide standalone design work for individual parts. Instead, we integrate design and subsequent production services. Each time we evaluate production for you, our engineers will conduct a free Design for Manufacturing (DFM) assessment. This ensures we can deliver our manufacturing services most efficiently and cost-effectively possible.

Typically, we require three critical pieces of information to provide you with production and pricing assessments: production drawings (either 3D files or 2D drawings), quantity, and the materials used. If any specific surface treatments are needed, please specify these in your email or on the inquiry form. However, we will need 2d drawings annotated with critical tolerances and dimensional specifications for parts with special tolerance requirements to ensure our engineers fully understand your needs.

Overall, the required information revolves around your production project. If the information you provide sufficiently describes the parts or products you need manufactured, our engineers can then proceed with production and pricing assessments. If you have any questions, please don’t hesitate to contact us for more information.

For simple production projects, our turnaround time can be as quick as 2-3 days. For standard projects, the typical lead time is 3-5 days. For complex or bulk projects, the timeline will depend on the specific requirements

You can view our surface finishing options on the Surface Finishing Options page. Additionally, if you don’t find the specific surface treatment you need, please don’t hesitate to contact us for assistance. We’re here to help！
