Technology of BENTEK

NPF (Net shape via Press Forging ) is a new process, just like the expression, which compound forging and press stamping advantages. but it does not means simply combining the two methods. In fact it has gathered so much Know-How and technique that makes the new process to be a new technology.

By using basic means such as forging, blanking, piercing, coining, drawing , bending and extruding, and so on, material like coil or other phase is able to be rapidly formed into complicated shape precision 3-D parts that traditional stamping work cannot carry out. It is really a innovative technology matching smart production, green production and lean production.

Advantages of NPF compared with other methods

NPF has higher performance and lower cost compared with other methods for metal parts work.

By-cutting method

The Processing Method of Changing (Reducing) the Volume of Material. For example: turning, milling, grinding, etc.

Non-cutting method

Do not change the volume of material even increase the volume of material, For example: casting, sintering, MIM, die casting, forging, RP, welding, assembly, etc.

NPF is a Non-cutting process, which forms the parts just in seconds without additional works. So fast and low cost.

Technical factor index

Applications of NPF method

Automotive Functional Components
Aircraft Parts
Electronic industrial parts
IT parts
Precision machinery parts,
Medical component parts,
Clean energy-related component
Leisure equipment parts
Environmental protection-related components

NPF Technical Level
1.Precision 0.005mm
2.Surface flatness 0.25μm
3.Min Teeth module 0.15
4.Draw over 0.1mm

   Development flow

Standard tooling needs only four steps to complete. Non standard dies for press forging technology has to add the trial process and production technology development process.

Strong process conversion brings added value for the customer

Fields convertible to be instead of

1. Machining by lathe or milling

2. Metal Sintering or MIM

3. Die-cast or aluminum forging

4. Lost wax precision casting

5. Grinding or policing

6. Caulking or weld assembly

7. Fine Blanking
