Home - Service - Rapid Prototyping

Rapid Prototype(RP) is a physical part that reflects the design intention. One or several samples been made according to the CAD drawing to check the rationality of appearance or structure.

Usually, the first step is to check the feasibility of a newly developed or designed product, which relies on prototypes in the process as it can identify flaws or abnormals efficiently. deficiencies and disadvantages of the designed product which can help improving the product defects at the point. A small trail production is usually done for improving flaws in the batch as the newly designed products normally come with issues. It will also cause a great deal of loss in material resources and time if to put into production directly. Thus, the prototype literally is just few samples and the process is labor saving, material saving, and time saving. By it’s appearance and testing the prototype, we can quickly find out the insufficient of product design and can improve it, so as to provide sufficient basis for mass production.

In order to support our customers to gain more competitiveness in the market , Our strategic partner is not only equipped with a variety of manufacturing and processing equipment, but also has a group of professional manual craftsman with years of practical experience. We specialized in making difficult, flexible and creative product models that cannot be completed by machining, and can quickly complete samples according to our customers’ needs, which saves a lot of your time.

What is the purpose of prototypes or why use prototypes?

   •  In prototyping industry, a prototype will be made to test if the size, appearance and structure etc, is reasonable, after the CAD drawing for the new product design completed.
   •  From which we can find out the deficiencies of a product design, and then to modify it appropriately.

   •  Prototype is a combined process that integrates various processing methods to produce samples that meet our requirements. We Heran mainly makes prototypes 

    by increasing and reducing materials.

What are the uses of prototypes?

   Prototypes can improve the work efficiency in the R & D department, reducethe risk of product development cost, time. 

   It also helps the verification in some structural performance in the R & D process.

Our advantages

   •  Dozens of prototyping manufacturing methods, including 3D printing, CNCmachining, Vacuum Casting(Urethane Casting), RIM, etc.

   •  More than 10 years’ experience in prototype industry

   •  Capable of making all kinds of high-precision, difficult and particularly complex prototypes.

   •  Offer free evaluation for the future mass production possibilities.
   •  Able to run each project at low cost.
   •  No material restrictions.

Rapid Prototype Manufacturing Service


    CNC Machining

    Main processing methods of rapid prototype,CNC is a computerized numerical  control machine equipment, 

    which cuts a whole plate by controlling the tool path according to the programmed program. 

    At present, it is the most widely used machining process domestically.

    The main plastic materials are ABS, PC, POM, PMMA, etc.

    The main metal materials are aluminum, steel, copper… And so on.

    CNC milling machines aims to fabricate some irregular products.

    CNC lathe is used to manufacture some round parts.

    CNC milling can manufacture some large parts, which is cheaper than SLA  and suitable for many kinds of prototypes.

    Up to 3000 × 1200× 600mm in size, accuracy +-0.1mm

     3D Printing & Machining Capabilities

     • Selective Laser Melting - SLM 3D Printing
     • Direct metal laser sintering - DMLS 3D Printing
     • Stereolithography - SLA 3D Printing
     • Selective laser sintering - SLS 3D Printing
     • PolyJet 3D Printing
     • Surface Finish and Assembly

     3D Printing Materials

     Metals : Aluminum ,Stainless Steel ,Titanium, Inconel, Cobalt Chrome, Copper .

     Plastics : Nylon ABS Polyethylene Polycarbonate TPU

     3D Printing Parts Surface Finishing Options: Powder Coating/ Bead Blasting/ Polishing/ Painting


     Sheet Metal Fabrication

    Sheet metal is a kind of comprehensive cold processing for sheet metals 

    Usually less than 8mm in length 

    Including shearing, stamping, laser cutting, bending, welding, riveting, splicing and forming. 

    Its remarkable feature is the same thickness in the same part, 

    and been widely used in products such as enclosures and covers.

    Sheet metal materials: aluminum, copper, steel and other metal plates, 

    Plastic materials can also be used for bending.

    Please click below for more detail of sheet metal.




    Vacuum Casting or Urethane Casting

    Firstly, a silicone is made by putting the prototype in a vacuum environment in which filling it

    with polyurethane materials so the replica can be duplicated through the process. It minimizes

    the risks during production and offers advantages, like high efficiency and low cost.

    • Mold materials: imported silicone, transparent silicone, special silicone.
    • Product materials: imported PU, transparent PU, soft PU, POM, ABS, PP, PC, high temperature resistant ABS, etc.
    • Diagram of vacuum casting molding.

    • Vacuum Casting Steps

    • Closed silicone mold—Vacuumize–polyurethane resin 

      and curing agent— Casting— Curing — Open the mold and get the copies



3D Metal printing


•3D Metal printing (DMLS)is to melt metal powder materials into the three-dimensional shape of the CAD drawings through high-temperature nozzle.

3D Metal printing can produce products with complex shapes which 

may not be completed by CNC, or the processing cost of CNC is too high.

•Heran’s 3D metal printing materials mainly includes stainless steel, 

aluminum alloy and titanium alloy.

Aluminum rapid mold or mild steel rapid mold

Use CNC, EDM, high-speed EDM and other equipment to 

fabricate metal and other hard metal materials such as aluminum

 or low carbon steel into molds (the lifetime of molds can reach 

more than 10000 times).

Product materials: ABS, PC, PP, POM, PMMA and

 other plastic materials.
