Custom Sheet metal Fabrication Forming Bending Welding stamping Parts
Progressive die stamping
Progressive die stamping uses a sequence of stamping stations. A
metal coil is fed into a reciprocating stamping press with
progressive stamping dies. The die moves with the press, and when
the press moves down the die closes to stamp the metal and form the
part. When the press moves up, the metal moves horizontally along
to the next station. These movements must be precisely aligned as
the part is still connected to the metal strip. The final station
separates the newly-fabricated part from the rest of the metal.
Progressive die stamping is ideal for long runs, because the dies
last a long time without becoming damaged, and the process is
highly repeatable. Each step in the process performs a different
cut, bend, or punching operation on the metal, thus gradually
achieving the desired end-product shape and design. It is also a
faster process with a limited amount of wasted scrap.
Transfer Die Stamping
Transfer die stamping is similar to progressive die stamping, but
the part is separated from the metal trip early on in the process
and is transferred from one stamping station to the next by another
mechanical transport system, such as a conveyor belt. This process
is usually used on larger parts that may need to be transferred to
different presses.

| About us | Our company was founded in October, 2000, specializing in the production of CNC/AUTO lathe, springs, shafts, screws, stamping parts and other metal parts. Our main production modes are designing and proofing based on customers’ drawings or samples. |
Bending: When you are designing the bends into your stamped metal part, it
is important to allow for enough material — make sure to design
your part and its blank so that there is enough material to perform
the bend. Some important factors to remember:
Coining: This action is when the edges of a stamped metal part are struck
to flatten or break the burr; this can create a much smoother edge
in the coined area of the part geometry; this can also add
additional strength to localized areas of the part and this can be
utilized to avoid secondary process like deburring and grinding.
Our company has strong R&D capability and develops many new products every year. In production, we strictly follow the ISO 9001 quality system to control quality and arrange production:
1. Don’t accept defective, strict inspection of supplier's raw materials.
2. Don’t manufacture defective, the production process is strictly controlled. For all products, the workers are strictly self-inspected on each machining process, and the quality inspectors do a regular inspection and spot inspection.
3. Don’t transferring defective, the defective products found in the previous process shall never be allowed to be transferred to the next process. Before shipment, the finished products shall be inspected again, and if any quality problems are found, and the products shall be reworked or rejected according to the relevant requirement.
Four-slide stamping is also called multi-slide or four-way stamping. This technique is best-suited for crafting complex components that have numerous bends or twists. It uses four sliding tools, instead of one vertical slide, to shape the workpiece through multiple deformations. Two slides, or rams, strike the workpiece horizontally to shape it, and no dies are used. Multi-slide stamping can also have more than four moving slides.
Four-slide stamping is a very versatile type of stamping, as different tools can be attached to each slide. It also has a relatively low cost, and production is fast.
Fine blanking, also known as fine-edge blanking, is valuable for providing high accuracy and smooth edges. Usually done on a hydraulic or mechanical press, or by a combination of the two, fine blanking operations consist of three distinct movements:
Fine blanking presses operate at higher pressures than those used in conventional stamping operations, hence tools and machinery need to be designed with these higher operating pressures in mind.
The edges that are produced from fine blanking avoid fractures as produced with conventional tooling and surface flatness can exceed that available from other stamping methods. Since it is a cold extrusion technique, fine blanking is a single-step process, reducing the overall costs of fabrication
