Stamping Parts Production Lines
As a one-stop shop and supplier for all machining services, we have invested in a stamping factory with high-speed presses, mechanical presses, and pneumatic presses ranging from 3T to 110T, including one dual-spindle 110-ton pneumatic stamping machine, to offer our clients a variety of stamping production services such as deep drawing, blanking, bending, etc.
Furthermore, we are also capable of NCT automatic punching, laser cutting, laser welding services to extend our stamping production line capabilities.
What is a Stamping Part?
A stamping part is made by a stamping mold that forms the metal into shape by blanking, piercing, drawing, bending, and embossing. Both single-stage stamping molds and progressive stamping molds can produce the required metal form via every stroke of the press.
A single-stage stamping mold, featuring a simple structure and lower cost, is generally designed and built for a single stamping operation.
A progressive stamping mold features a set of dies for various stamping operations in a row, where a metal strip moves through one stage per punch. However, a progressive stamping mold is more expensive than a single-stage one and is usually recommended for high-throughput products or complex workpieces. Contact our team for a project review, and our engineers will check and advise in detail.
Stamping-Deep Drawing
Deep drawing is a sheet metal forming process of stamping in which the sheet metal is radially drawn into forming dies by the continuous mechanical action of several punches. It is thus a shape transformation process with material retention. The process is called "deep" drawing when the depth of the drawn part exceeds its diameter.
Stamping-Blanking
A shearing cutting process of stamping, featured by a punch and a die to define the hole profile on metal sheet.
Stamping-Bending
To produce V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly metal sheet.

In Addition To CNC Machining Services
In addition to parts made by CNC machining, an instrument or machine may be assembled from many other kinds of spare parts. For example,
- frame chassis, support structure made of metal sheet, produced from stamping machine
- electrical insulator, chassis of instrument or chemical resistance container made of plastic, produced from plastic injection molding
- electronic connectors/housings, light shell/heatsink, device bracket made of aluminum, manufactured from die casting molding
As a one-stop shop for all parts manufacturing services, we also provide tooling for plastic injection, die casting, and stamping services. The R&D team at Apporo has marvelous manufacturing experience and knowledge, and our clients often comment on how gorgeous our machining workmanship is.
Stamping, Casting and Injection Molding Compared To CNC Machining
CNC machining is not the only way for large scale precision parts mass production. We also offer various production methods to enhance our core services:
- Stamping
- Manufacturing parts from metal sheet which is supplied with limited kinds of thickness.
- Part features can be formed in a single step at a high frequency.
- Progressive stamping molds are highly recommended for high speed, complex, or tiny parts production.
- Much more cost-effective compared to the CNC manufacturing process for large-scale mass production.
- Deep drawing mold can offer a much more flexible manufacturing method for sheet metal forming.
- Aluminum die casting
- An alternative metal forming production for 5-axis CNC production, but parts will have draft angles on their internal or external surfaces.
- Feasible for thin shell, heat sink, complex profile parts production.
- Much more cost-effective compared to the CNC machining process for large-scale mass production.
- Capable of various kinds of surface treatment, such as nickel plating, electroless nickel plating, powder coating, liquid coating.
- Production speed of aluminum die casting can be much higher.
- Injection molding
- An alternative plastic forming production for 5-axis CNC production, but parts will have draft angles on their internal or external surfaces.
- Much more cost-effective compared to the CNC machining process for large-scale mass production.
- Production speed of injection molding can be much higher.
- Capable of manufacturing parts made of thermoplastic compounds that offer excellent colorability, clarity, flexibility, and elasticity.
Apart from the above, parts manufactured via CNC could be generally stronger and have much better production quality and finish. Eventually, CNC machining is typically used from early to late stages of project development whenever parts are ready to be sample tested for functional accuracy or mass production.
