Sheet Metal Prototyping

What is Sheet Metal Fabrication?

Sheet metal fabrication is a set of manufacturing processes used to turn sheet metal stock into functional parts. The sheet metal is usually between 0.006 and 0.25 inches (0.015 and 0.635 centimeters) thick.


There are several processes that fall under the umbrella of ‘sheet metal fabrication’. These include cutting, bending and punching, and can be used either in tandem or individually.


Sheet metal fabrication can be used to create either functional prototypes or end-use parts, but end-use sheet metal parts generally require a finishing process before they are ready for market.

After two years, we successfully developed relationships with a handful of medium-size casting partners who can meet our quality requirements and lead time requests. We are now able to offer high-pressure die casting in aluminum, magnesium and zinc, as well as investment casting in brass and all types of steel.

Why use Rons for Metal Casting?

It might sound counterintuitive to use an RP company for metal casting services, but we offer very good reasons for doing so:


We have built up an excellent relationship with our partners for pressure die casting and investment casting.

We have a huge amount of precision CNC machines for post-machining

Rons Advantages of CNC Milling

Cost Efficient

Most aspects and mechanical parts can be CNC milled within minutes or seconds by optimizing tool paths and special cutting tools. With automatic programming, CNC milling is most cost efficient for both low and high volume production comparing with additive manufacturing.

Materials & Finishes Options

We provide more than 50 types plastic and metal block with different specifications for CNC milling. In addition, different surface finishing is available for milling parts, such as painting, anodizing and chroming. This will combine function and appearance process greatly.

Complexity Requirement

Our multi-axis milling machines can create CNC milling components with complex shapes by approaching work-piece form different angles. Especially for irregular shapes.

Custom Surface Finishes

You can select various surface finishes on solid metal and plastic parts from precise design specifications. We provide different surface finishes such as standard machined, smoothed, bead blasted, anodized clear or color, anodized hard-coat, power coated, electropolished, black oxide, chromate conversion coating, brushing.

+/- 0.0005’’Tolerance

Our minimum tolerance of milled parts has achieved +/-0.0001’’, as our typical tolerance is +/-0.0005’’, this will vary due to component size and material types.

CNC Milling Metals

CNC aluminum machining is our main part of Runsom CNC service catalog, we also provide CNC milling for various metals, such as steel, stainless steel,magnesium, brass,copper, bronze, titanium, zinc and nickel alloy. Sterling Silver, Bronze, and graphite.


We cooperate with partners from automotive, aerospace, medical and electronics industries to provide different aluminium CNC milling parts as engines, enclosures, heat-sinks and frames. We can produce great accuracy and superior surface finish parts with aluminum materials in the reason of its great mental machinability.

Casting Materials & Finishes









Powder coating


The type of cutting machine used depends on the chosen material and the gauge of the sheet, as well as factors like desired lead time and tolerances.

We know which projects need which equipment, so you don’t need to specify a particular cutting machine.

In general, a part that is cut, bent and punched will cost more than a part that is, for example, just cut using a laser cutter.

However, most sheet metal parts demand a combination of forming processes, and this will not increase the price by a drastic amount.

No. You can order a one-off prototype or 1,000+ units002E.
