We offer free ground shipping limited to customers in Taiwan and China. For other locations, our sales and fulfillment team will work with the carriers of your choice.

We understand that your 3D data and designs are invaluable to your business. Therefore, we take the protection of your intellectual property rights (IPR) very seriously. We encrypt all files that are transferred using SSL, ensuring that they can’t be intercepted while being uploaded to our servers.All the information and any files which you upload onto our platform are stored securely, and only ever shared within our organization with those employees who need access to it in order to manufacture your parts.

We ensure confidentiality across the entirety of your order; original drawings are not shared with 3rd party suppliers as all our production is done in-house.If you would like some additional reassurance, we can sign a Non-Disclosure Agreement.

JC Machining has a CNC manufacturing team of professional engineers and machinists to reduce manufacturing redundancy, optimize CNC programming, shorten machining time, improve surface finish, and deliver the best quality machined parts.We take each project personally and carefully examine each drawing, we can then enhance the 2D/3D designs by adding clarity and detailed information and further analyze your design to accommodate any special fixturing and machining strategies used to produce your parts at a very reasonable cost.

Our manufacturing team follows strict quality control standards, delivering 100% accuracy at strict tolerances. You can also call or email us at any time, and we’ll help with ordering parts, design feedback, material recommendations, and answer any questions.
