Sheet Metal Fabrication Service

What is Sheet Metal Processing?
 

Sheet metal process or sheet metal fabrication includes: folding, shearing, punching, welding, riveting, splicing and other processes. In general, the process of forming a sheet by hand or mechanical is called sheet metal processing. Sheet metal processing is to cut and bend metal materials into various shapes and their thicknesses can vary significantly. According to the materials, sheet metal fabrication can be divided into several types, including aluminum sheet metal fabrication, stainless steel fabrication and brass fabrication. 

Sheet metal process:

Sheet metal processing drawing design -> Laser processing or (CNC stamping) -> Bending -> Welding Molding -> Electrostatic powder spraying or (liquid paint) -> Packaging and shipping.

1. Drawing design:

In general, the customer provide drawings or samples, then our engineers perform the measurement, design, and development, and form the machining decomposition map and assembly drawing to the production department for processing.

2. Laser processing:

It has a large laser cutting machine, it can be cut by laser cutting  such as carbon steel, stainless steel, etc material. After the workpiece is processed, the section is neat, smooth and beautiful, and the size is accurate. It has advantages for the workpiece with arc. CNC stamping can not replace the processing method.

3. CNC stamping:

With imported turret CNC punching machine, CNC punching is mainly for the thickness of product processing materials, generally suitable for materials below 2.5mm. Sheet metal processing workpieces have more holes or need to open special molds to process the workpiece. CNC punching has a certain cost advantage.

4. Bend:

After the workpiece is cut, if most of them need to be bent and formed, the CNC bending machine not only has a fast speed, but also the workpiece is processed more accurately.

5. Welding molding:

The workpiece needs to be assembled and formed after cutting the material, and the assembly method is various. Some are directly formed by non-welding processes such as screws and riveting. Generally, the mechanical casing is made of welding, and the company adopts argon arc welding, bump welding, carbon dioxide welding, etc., we will polished them after welding, so that the workpiece is relatively firm and beautiful.

6. Electrostatic powder spray:

Electrostatic powder spraying is mainly for carbon steel workpieces. In the process, oil removal and derusting, surface cleaning, phosphating, electrostatic powder spraying and high temperature baking are generally carried out. After processing, the surface of the workpiece is beautiful, it will not rust within a few years, and the cost is low.

Liquid paint: This process differs from electrostatic powder spray. It is mainly used for large workpieces. It is convenient and low-cost to use liquid paint when it cannot be handled. The liquid paint is divided into two steps, and the primer is applied to the paint after the workpiece is processed.

7. Packaging and shipping:

100% inspection before packaging and inspection data.

Advantages of Sheet Metal

Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, large-scale mass production performance, etc. It has been widely used in the fields of electronics, telecommunications, automotive industry, medical equipment and so on. For example, in computer cases, mobile phones, and MP3s, sheet metal is an essential part.

CNC Machining Services

What is CNC Machining?

CNC machine offered by cnc machining companies in china is commonly used in manufacturing and industrial production. But exactly what is CNC machining?

CNC (Computer Numerical Control) machining is a kind of subtractive manufacturing process. In CNC manufacturing, the software control system issues commands to make the tool meet the required movements. In this process,various precision tools are used to remove layers of raw materials and make parts or products. Therefore, it can also be called cnc precision machining.

Types of CNC Machining

Three-axis CNC machining

The 3-axis machining is performed by straight lines to the axes X, Y, and Z. 
Machining features: the cutting tool orientation remains constant during movement along the entire cutting path. 
The 3-axis machining center has the advantages of high precision and high efficiency. It is commonly used to machine general parts, but it is more troublesome when machining complex workpieces, which may cause the workpiece to fail. Therefore, multi-axis simultaneous machining is the first choice when machining more complex workpieces.
Three-axis CNC machining

Five-axis CNC machining

Five-axis machining is the use of CNC to move parts or cutting tools on five different axes simultaneously, which can process very complex parts. 
The remarkable feature of the five-axis linkage CNC machine tool is that it can complete the surface machining, and no special fixture is needed during machining, which greatly reduces the number of clamping and improves the machining accuracy, quality and efficiency. The five-axis machining center has unparalleled advantages in the processing of complex workpieces.
Five-axis CNC machining

CNC milling

CNC milling machine processing is based on the technical requirements of the shape, accuracy, size and surface roughness of the workpiece to determine the processing technology and processing parameters. Program the machining program into the controller and send the command to the servo. CNC milling machines can process parts with particularly complex contours or difficult to control dimensions, such as mold parts and housing parts. It has the advantages of strong adaptability, high processing precision, stable processing quality and high efficiency.

CNC turning

CNC turning is one of the most used machining methods in CNC machining. During CNC turning, the workpiece makes a rotary motion, and the tool moves in a straight line or a curve. While the tool tip moves relative to the workpiece, a certain workpiece material is removed to form a corresponding workpiece surface.

With only thirty years around of development, rapid prototyping technology, as its name implies, has already been widely used in many areas. Meanwhile, the rapid prototyping services are still growing at a fast speed.

Different Rapid Prototyping Processes

Prototypes can be made through different rapid prototyping processes. With thirty years around of development, a variety of prototype manufacturing processes are available. In addition, they are continuing to evolve. Since companies or customers have different requirements and demands, different types of rapid prototyping processes will be chosen. So how does rapid prototyping work? Reading the following contents and you will know which rapid prototyping service suits you best.
 

SLA(StereoLithography)

  • Description: SLA is a photo-curing molding technology, which refers to the method of forming three-dimensional solid layer by layer through the polymerization reaction of liquid photosensitive resin by ultraviolet irradiation. The work piece prepared by SLA has high dimensional accuracy and is the earliest commercial 3D printing technology.
  • Printing Material: Photosensitive Resin
  • Strength: photosensitive resin is insufficient in toughness and strength and is easily broken. At the same time, under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.
  • Features of finished product: SLA printed workpieces have good details and smooth surface, which can be colored by spray painting and other processes.
 
Selective Laser Sintering (SLS)
  • Description:SLS is a selective laser sintering technology, similar to SLM technology. The difference is the laser power. It is a rapid prototyping method that uses infrared laser as a heat source to sinter powder materials and form three-dimensional parts layer-by-layer.
  • Printing Material:Nylon powder, PS powder, PP powder, metal powder, ceramic powder, resin sand and coated sand (common printing materials: nylon powder, nylon plus glass fiber)
  • Strength:material performance is better than ABS products, and the strength and toughness are excellent.
  • Features of finished product:the finished product has superior mechanical properties and is suitable for direct production of measurement models, functional models and small batch of plastic parts. The disadvantage is that the precision is not high, the surface of the prototype is relatively rough, and it is generally required to be polished by hand, sprayed with glass beads, ash, oil and other post-processing.

Fused Deposition Modeling (FDM)

  • Description: FDM is a melt lamination technology, that uses high temperature to melt materials, extrudes them into filaments through the print head, and builds up on component platform. FDM is the simplest and most common 3D printing technology, which is commonly used in desktop 3D printing devices.
  • Printing Material:usually ABS or PLA wire
  • Strength: PLA is brittle,its surface hardness is higher, and it is easier to break when bending. ABS parts are more resilient than PLA parts, and are easy to bend rather than break under pressure. Moreover, ABS has higher strength, better plasticity, and easier post-processing.
  • Features of finished product: the printing layer is thick, the precision is poor, and the stratification of the surface is very obvious. Under high temperature conditions, the printed parts are easy to bend and deform, and the bearing capacity is insufficient.
 
CNC
  • Description: CNC machining is a subtractive manufacturing process in which the software control system issues instructions to make the tool perform various required movements. In this process, various precision tools are used to remove the raw materials and make parts or products.
  • Materials: CNC processing materials are quite extensive, including plastics and metals. Plastic hand model materials are: ABS, acrylic, PP, PC, POM, nylon, bakelite, etc.; Metal hand model materials are: aluminum, aluminum Magnesium alloy, aluminum zinc alloy, copper, steel, iron, etc.
  • Strength: different materials have different strengths and are difficult to list
  • Features of finished product: CNC machined parts have a smooth surface, high dimensional accuracy, and the best compactness, and there are a variety of post-processing options.
 

Vacuum Casting

  • Description: vacuum casting technology is to use the prototype (rapid prototyping parts, CNC hand parts) to make a silicone rapid prototyping mold under vacuum condition. It also uses PU, ABS and other materials to pour, so as to clone the same copy with the product prototype.
  • Material: ABS, PU, PVC, silicone, transparent ABS
  • Strength: the strength and hardness are lower than the CNC hand parts. Common PU material is relatively brittle, toughness and high temperature resistance are poor. ABS has higher strength, better plasticity, and easier post-processing.
  • Features of finished product: easy to shrink and deform; the accuracy is generally only 0.2mm. In addition, the vacuum casting hand parts can only resist high temperature of about 60 degrees, and is lower than CNC hand parts in strength and hardness.
 

Advantages of Rapid Prototyping
