We just completed a new medical project – prototypes of a maternity TENS machine.
A maternity TENS machine, is a device designed to provide pain relief during labor and delivery. TENS stands for "Transcutaneous Electrical Nerve Stimulation," and the machine works by sending low-frequency electrical impulses through electrodes placed on the skin. The electrical impulses stimulate the nerves, which can help to block the transmission of pain signals to the brain. This can provide a natural and drug-free form of pain relief for women in labor.
We work with our customers on the DFM(design for manufacturing) of mechanical parts. We discussed the product requirements, the material of the parts, and the manufacturing process for each part. Then we identify those areas where the design could be improved to make it easier and more cost-effective to manufacture. In the end, we simplified the design, reduced the number of components, and changed the materials used in a couple of parts.
The second step is physically to build those prototypes. These prototypes allow their engineers to test the design, identify potential issues, and make improvements before building the injection molds.
The first step in building a prototype is to prepare all of the necessary materials and components. This includes raw materials such as metal, plastic, and fasteners. Some parts require RIM, some require vacuum forming, some require CNC machining, and some need to be 3D printed.
For CNC machined parts and 3D printed parts, we need 3D models to program the machine to make them.
For the vacuum-formed parts, we 3D printed a masterpiece, and get it measured to make sure it meets our dimensional requirements. Then we built the silicon mold for it. We fill the material into the silicon mold under the vacuum. Secondary processing and finishing are needed after that.
For the RIM parts, we machined aluminum molds with the 3D models. We fill the mold with mixed liquid material. Secondary processing, painting, and printing were done after those parts solidified.
We did the full dimensional inspection on all the parts. Then we did all kinds of functional testing with our customers to simulate the machine’s working environment.
At the end, our customer is very happy, they said they loved the whole process of working with Goodtech engineers. The communication, technical support, lead time and price are all beyond their expectations.
