Sheet metal parts in the home appliance industry commonly require the processing of mounting threaded holes. Traditional processes involve stamping, followed by transfer to separate equipment for secondary tapping, resulting in fragmented processes and time-consuming turnover.
In-mold tapping technology enables simultaneous, integrated stamping and tapping, perfectly suited to the continuous, high-speed mass production model of the home appliance industry, significantly reducing processing cycles.
Simultaneously, it eliminates the need for semi-finished product transfer and secondary loading/unloading, facilitating the construction of fully automated stamping production lines and meeting the intelligent upgrading needs of home appliance manufacturers.
The case study demonstrates its application on the compressor base plate.
The motor housing has a large number of threaded holes and is produced in large quantities. The long-term vibration of the equipment places extremely high demands on the thread strength and the cleanliness of the housing.
Compared with the traditional post-processed multi-axis tapping process, in-mold tapping can complete the tapping process simultaneously during the stamping stage, which is suitable for continuous stamping and significantly improves the production cycle time. The extrusion molding process eliminates the residue of cutting chips.
This case study demonstrates the application of a tapping station on a motor housing.
Using in-mold tapping in automotive parts production unifies the machining datum with stamping, resulting in higher thread and hole accuracy and meeting the stringent tolerance standards of automotive parts.
It enables full-process production with raw materials, eliminating tooling clamping and pressure damage to sheet metal, and reducing shaping processes.
It also eliminates the need for multiple transfers of semi-finished products, reducing bumps and defects and improving first-pass yield.
This case demonstrates the application of tapping unit in the production of automotive parts.
In-mold tapping units have a wide range of applications in various general hardware parts fields. Relying on progressive dies, they can complete punching, forming, tapping, and blanking simultaneously in one go. Whether it is the fine threads of thin-film micro precision hardware or the heavy-duty threads of thick-plate building supports and bathroom accessories, they can be processed stably.
In-mold tapping is gradually becoming the preferred process for mass production of various hardware parts.
This is a case study of hardware parts manufacturing.
