3. Sealing structure and producing Precision
a superbly tough portion is useless if it are unable to create an excellent seal. study the design attributes carefully. The quality of the bundled O-rings or gaskets is critical; they should be made out of significant-quality products like Viton that resist chemical breakdown from present day coolants. Furthermore, the machining from the part by itself should be precise. The mating surfaces needs to be properly flat, and the bolt holes have to align particularly Using the motor block to make sure even clamping strain plus a leak-proof match.
four. model status and following-gross sales help
