Precision Metal Thread Forming & Tapping

Everyone involved in designing and production of automotive electronics parts understands that tapping is a delicate exercise: automotive gearbox housings are of high-strength steel, and deep tapping marks the tool; electronic connector terminals are of thin-walled aluminum, and even a small amount of force will bend them; more problematic is the fact that changing the parameters with each production change may require half a day to cut qualified parts. This is a thread forming/tapping process with the specific design intention to address these issues. It uses automobile hard metal and soft electronic component processing logics which are customized. The threads formed are dimensionally accurate and assembled smoothly, and meet assembly criteria of automotive quality and precision standards of electronic components, a first-pass yield in mass production is always above 99%.

Its main strength is its dual-mode flexibility, which means that one is not required to switch procedures between hard and soft materials. In aluminum, copper and magnesium alloys which are a common material in electronics the thread forming mode, which is a chip-free machining, ensures that the metal fragments do not become lodged in micro-terminals and have no impact on conductivity. Upon hitting hard metals, such as carbon steel and stainless steel, such as automotive chassis components and engine fittings, it automatically engages the cutting mode where the cutting edge of the tool is pushed uniformly along a predetermined path, and even large diameter M16 threading will be chip free.

And, between the holes micro-threaded in the M1 of the mid-frame of the phone and the fixing threads of the M16 of the gearbox housing, everything is included in the specifications, enabling the production to be smooth without the necessity of altering equipment.

Because even small mistakes in automobile electrical components might prevent assembly, precision is entirely worry-free. Real-time monitoring and pre-positioning calibration are included in the procedure. In order to ensure that thread size deviations are controlled within ±0.015mm and that thread peak and valley fit exceeds 98%, the center point is precisely identified prior to cutting during machining. For instance, the mounting threads of the phone's mid-frame prevent stripping even when fully screwed in, thus minimizing the inconvenience of rework during subsequent assembly; the fixing threads of automobile brake pad brackets, for instance, have almost no play after bolting.
