Generally wireless microphone housing parts are turned inside and outside by CNC lathe on-site tooling, and then CNC machining or 5-axis machining is used to complete the other steps, FULFIL 5-axis machining manufacturer enables you to complete the parts at low cost.

How does VMT use cold hydraulic drawing technology with CNC machining to complete a high quality brand wireless microphone housing part?

When we first started machining the main body housing of this microphone, the process was bar stock + CNC machining, which wasted material and took a long time to process.

After the mass production, in order to meet the customer's demand, our engineers changed the process to extrusion + CNC machining, the processing cost directly decreased by 50%, and the quality also meets the customer's requirements.

For high quality round tube aluminum parts, our traditional machining method is to use aluminum rods, which has a big disadvantage that the machining time is long and the raw material is also wasted. In the case that the material remains unchanged, the effective processing method is to use hydraulic extrusion to stretch out the embryo after the 5-axis machining method to complete the other steps, so that the parts can be completed at low cost.

Step 1: Machining and cutting with a 200T stretching machine.

Before hydraulic stretching we make a skin film on the surface of the raw material and reduce the hardness to 0 state, the purpose of this is to facilitate the mobility of the raw material in the mold sufficiently, so that a high-quality embryo is produced.

Step 2: CNC lathe machining the outer surface and inner wall.

Parts processing time we first want to confirm is a benchmark size, because the lathe processing of a part is difficult to a process can be completed, as long as the parts are divided into several times to complete the parts must be determined to ensure that a benchmark to ensure that the size of the process behind the off-chain, which is to ensure that the production process of mass production of dimensional stability of the key factors.

Step 3: Wireless microphone shell CNC machining of the mouth threads and key holes.

The size tolerance of each keyhole we have to use easy to detect the gauge to control the consistency here, and the keyhole is prone to produce sharp corners, in the surface treatment of the spraying is easy to product white bad, which is the key to the control of this process.

Step 4: Spray the oil.

Step 5: Silkscreen.

Eventually reached the customer's needs, processing costs have been reduced, the customer is very satisfied, recognized our service attitude, and later reached a long-term strategic partnership with us.
