Frequently Asked Questions
Custom Parts Manufacturing Capabilities
Strict quality control in precision machining workshops ensures the quality of complex parts prototypes to final products.
Can aluminum be welded?
Aluminum is a tricky material to weld. Tuofa has the trained welders with experience and proper equipment for welding aluminum, even light-gauge aluminum components, including retail shelving, cabinets, electrical boxes and support framework.
Can you provide finishing services?
Yes. Many of our customers take advantage of our wonderful relationships we have with outside vendors to provide finishing services such as anodizing, passivation, plating, polishing, grinding, and heat treating.
Do we machining plastics?
Yes. We regularly machining PVC, Peek, Teflon, Delrin, PPS, PDFE and others.
Can composite materials be machined?
We can machine most carbon-fiber composites, but special tooling is required, and experimentation must be done on each new part to set the correct feeds and speeds.
.What is the CNC Machining Process?
The process of CNC Machining is when the machining tool operation is automated by pre-programmed software. CNC stands for “Computer Numerical Control” which means, the complex machining and tool movement such as speed, coordination, and rate in which the part is fed into the machine is all controlled by software. CAD professionals design and draw up the part in the CAD program and then the machine carries out the repetitive movements rather than human operators so that consistent and precise parts production can be accomplished.
What's your QC system?
We can provide all kinds of testing certificates, material and dimensional inspection, etc.
How to enjoy the OEM services?
Usually, base on your design drawings or original samples, we give some technical proposals
and a quotation to you, after your agreement, we produce for you.
