Custom Aluminum CNC Milled Flowmeter （Protokomer） Assembly

Product Introduction

This part is a flowmeter housing used in the automotive industry. The automotive air flow meter is an important sensor of the car engine. Its core function is to detect the air intake of the engine and convert it into an electrical signal to transmit to the Engine Control Unit. Based on this signal, the ECU accurately controls the fuel injection quantity, enabling the air and fuel to be mixed in an optimal ratio. This ensures efficient combustion of the engine, stable power output, and can also optimize fuel economy and reduce exhaust pollutant emissions.

Material and process

The parts are made from aluminum alloy. There are several parts for this protokomer assembly, include body,adapter, cover and so on.

The housing are worked directly by aluminum billet, use 4 axis CNC machine.

The hole is pretty deep, and hard to work.

We use special deep hole drill machine to meet customer's requirement.

For the protokomer, below are the 3D drawings:

Regarding its structure, we hot forged the aluminum rod by hot press die, then heat treatment – anneal to make soft , and CNC milling and turning by programming.

It is ec-center for the main holes.

Apart from this, there are still has a ring to assembly and the ring need to make thread.

Packing

For flowmeter components, each part is individually wrapped with bubble wrap to safeguard the surface finish.

Then put them in cartons and laid on pallet, wrapped with protective film to avoid them scattering.
