The mechanical engineering design stage is extremely important in product development. It is in this stage that we design, develop, build and test the mechanical systems by using physics principles and materials science.
Haltian has developed mechanics for several demanding and extremely miniaturized products. For these products, special attention should be paid to DFA (Design for Assembly), DFM (Design for Manufacturability), and DFT (Design for Testing) at the very beginning of product development.
The first prototypes of mechanics are usually made by 3D printing, machining, or silicone molds. Sheet metal parts can be done with proto tools. In this way, the mechanics can be evaluated cost-effectively and based on the feedback, further developed towards mass production.
For demanding products, we can perform mechanical simulations in terms of reliability and water tightness. Highly efficient electronics generate a lot of heat that must be transferred out of the product in a controlled manner. Thermal simulation saves time and money on such products. We use computer-aided engineering (CAE) to perform thermodynamics and fluid mechanics including calculations, FEA, and CFD analysis to reduce the number of prototypes, and thereby the cost and time to get to a final design.
Similar to extreme miniaturization, water, dust-proof, and shock-proof needs careful design as sealing a device to meet these requirements will drive design decisions. Haltian has experience with IEC 60529 standards and has implemented IP codes up to IP68 (dust-tight and water-tight beyond 1 meter of submersion for over 30 minutes). We’re also quite experienced with shock-proof designs and products.
