What is a Prototype in Sheet Metal Fabrication?
A sheet metal prototype is a physical example that allows designers to test the function and form of a part prior to mass production. Sheet metal can be used to make both functional and non-functional prototypes. More interest from investors is possible with a prototype as it serves as a tangible example of a design’s durability and aesthetics. It is easier to transition from a metal prototype to the final version of a metal product than it is to transition from a plastic prototype to metal part.


Processes Used in Sheet Metal Prototyping

1. Laser Cutting Service

CAD/CAM and engineering capabilities, and machines equipped with automation. We can meet tolerances to ±0.15mm.Fiber laser cutting uses laser diodes transmitted through optical fibers to create desired cuts. The process makes less noise while decreasing any personal risk to the machine operator. Fiber laser cutting uses a high-power output and high-intensity level, making it a very efficient manufacturing process.

2. Water-Jet Cutting Service

Water-jet cutter is able to cut material without interfering with the material's inherent structure as there is no 'heat affected zone' or HAZ, this allows metals to be cut without harming or changing their intrinsic proerties.

5.Sheet Metal Stamping

During stamping, a blanked or coiled slit to width sheet metal is loaded in a press where the stamping tool is pressed onto the material. The stamping tool or die contains the desired shape of the part. Stamping may involve punching, blanking, bending, drawing, embossing and more.We offer experience in all areas of precision metal stamping processes. As a result, we can readily develop a full range of both standard and custom metal products. Some of those products include: deep drawn stampings (deep 3D parts) like pots and pans, metal brackets, spring clips, metal clips, exterior building panels (ex. roofs, doors, bonnets, side panels, deck lids and fenders), interior building panels, metal brackets, eyelets, lasers, gauges, radio system components, medical stampings, helicopter parts, vehicle engine parts, weapons parts, navigation systems, landing gears and dimensionally critical panels. Metal stamping is also used to make jewelry, household items and plumbing accessories.





6.cnc machining

CNC, or computer numerical control machining, is a widely used manufacturing process that uses automated, high-speed cutting tools to form designs from metal or plastic stock. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. Machines may vary in how CNC parts are cut—the workpiece may remain in place while the tool moves, the tool may remain in place while the workpiece is rotated and moved, or both the cutting tool and workpiece may move together.


Skilled machinists operate a CNC machine by programming tool paths based on the geometry of the final machined parts. The part geometry information is provided by a CAD (computer-aided design) model. CNC machines can cut almost any metal alloy and rigid plastic with high precision and repeatability, making custom machined parts suitable for nearly every industry, including aerospace, medical, robotics, electronics, and industrial. Hongmingsheng offers custom CNC quotes on over 40 materials ranging from commodity aluminum and acetal to advanced titanium and engineered plastics like PEEK and Teflon.


7.Production Etching

Like prototype etching, production etching uses photochemical machining or chemical milling to create metal parts with high precision and intricacies. Production etching is perfect for transitioning prototypes into production because it is fast, cost-effective and offers great design flexibility.




Our welding team uses a combination of heat and pressure to fuse two or more parts together. Welding services include arc welding, metal inert gas (MIG), tungsten inert gas (TIG), resistance spot welding, laser welding and oxyfuel welding and cutting.



9.Sanding/Grinding

Sanding and grinding services are both offered by Hongmingsheng. Grinding removes weld or adds any desired cosmetic surface. Sanding can remove scratches or burrs from parts after laser cutting or punching.


Surface finishes not only make prototypes and final products look aesthetically presentable and unique, but also crucial in ensuring that they can perform as intended to and last longer as finishes provide protection from outside elements, corrosion, wear and rust.

We has an entire finishing department, offering a full range of finishing services which range from simple one or two-stage process like cleaning, sanding in 3D printed parts to complex multi-stage process in prototypes, like painting or special surface treatments to meet even the most demanding applications. You can obtain the most realistic prototype for fit, form and function testing in project development, sales and marketing purposes when collaborating with us.




Quality Control Of Sheet Metal Fabrication

Strict quality control is HONGMING SHENG MFG’s corporate life. From raw materials to product packaging and transportation, every link is under our supervision, ensuring that 99% of high-quality sheet metal stamping Parts are delivered to customers.


01. Raw Material Quality Inspection
Long-run participation with large steel mills, all materials will have a material examination report by the sheet metal stamping company, HONGMING SHENG MFG. (chemical report and physical report) before they are put into storage.


02. Initial Size Inspection
Before the CNC milling services,Measure the size of the material to prevent insufficient machining allowance and poor material.


03. Production Interaction Control
Develop a production schedule flow chart, control time nodes and production plans, and prevent delayed delivery.


04. Mid-Term Dimensional Investigation
Pay attention to each cnc milling processing node, review possible quality risks during product processing, and stop the processing of problem products in time


05. Final Size Examination
Relying on advanced CMM and other inspection equipment to carry out size inspection on cnc milling parts.


06. Surface And Establishment Test Review
100% shape quality control, and install and test product functions, reject and isolate parts with quality problems such as scratches and unqualified surface treatments.
