1. PP Micro Foam Sheet Applacations:
PP foam sheet has a unique advantage, the density of more than 0.45g / cm3 PP foam has a good bending resilience, not easy to deformation, in the field of the folder has a broad use of the prospects of density 0.6g / cm3 PP hair Foam has good mechanical properties, in the field of automotive interior has a very broad future, can be processed into carpet support materials, shading board, noise board, luggage rack, interior trim, cover, box, etc .; density 0.3g / Cm3 PP foam sheet has a good flexibility and resilience, suitable for packaging, shelves and other fields.

2. Sheet Extrusion Line:
 **Extruder:  Appropriate single-screw extruder (exhaust or not) should be chosen on the basis of different materials. Specially designed screw and advanced temperature controlling system ensure the good plasticization, high output and stable extruding.
 

**Screen changer and mould:The quick screen changer of hydraulic system ensures the short course of screen changing without material-leakage. Reasonable structure of mould should be chosen in terms of material, whereas moulds of clothes-rack mode are widely accepted to regulate flow-distribution and guarantee even thickness of plates (sheets).

 

**Three-roller calendaring machine:Inclined and vertical three-roller calendaring machine should be chosen according to the thickness of the plates(sheets). Temperature controller operates separately and gap among the three rollers can be adjusted freely, and the central roller has special design of regulating angle. Both ensure the excellent calendaring effect and even thickness of plates (sheets).

 

**Bracket of cooling roller:Equipped with corresponding guide roller, the cooling effect is better. In addition, the edge-shearing device equipped can guarantee fixed width of plates (sheets) and quality of edge.

**Edge side cutting device online, so the side of sheet will be smooth and uniform, the cutting wastage can be reused for production
**Cutting side online crushing and recycling device, it can make the cutting wastage into small flakes.
**Haul-Off Device.
**Landscape orientation cutting machine:

It is of length-fixed cutting with cutting precision less than 2mm and adopts alloy blade or rigid alloy saw bit to ensure the good cutting effect and constantly stable performance.

 

**The winder 

It is of friction winder and other forms as well can be supplied according to customers'requirements

 

**Auto stacker

**Electricity control system:

Siemens PLC touch screen computer control, Schneider contractor, ABB inverter,Temperature control table RKC or OMRON.
 

**Raw material drying device and color mixing device.

 

3. Extrusion Line Characteristic:

1. Adopting the oversea advanced technology to make the optimization design with big screw L/D ratio and high production capacity.
2. To change the net by full-auto hydraulic changing net, easy and fast.
3. The upper and lower roll wheel of 3-roll calendar are adopted the hydraulic moving, the pressure can be adjusted, suitable for the different materials.
4. Adopting double station center winding for the winding device, matched the magnetic powder tension control.

4. Technical Parameters.

Sheet Metal Fabrication

Sheet Metal Fabrication

Definition of sheet metal fabrication

Sheet Metal fabrication is the creation of useful metallic parts and structures by the application of multiple fabrication processes. Sheet metal fabrication is basically a broad term that involves various complex processes like cutting, forming, bending, welding, machining, and assembling. The instructions include below: materials, processes, and tools required for sheet metal fabrication.

Types of Sheet Metal Fabrication Materials

The choice of metal depends on the final use of the fabricated parts.

Common fabrication processes:

· Carbon Steel

· Stainless Steel

· Aluminum

· Bronze

· Copper

· Brass

· Aluminized steel

· Galvanized steel

Types of Metal Fabrication Processes

The journey to the final product from raw sheet metals proceeds through various sheet metal fabrication processes. All the sheet metal fabrication processes can be grouped into the following three categories:

· Cutting

· Deformation

· Assembly

Sheet metal fabrication: Cutting

i. Laser Cutting

ii. Water jet cutting

iii. Plasma cutting

Sheet metal fabrication: Forming or Deformation

Bending: Sheet metal bending is one of the most popular deformation processes. A machine known as a Press brake is used to bend sheet metals into V, U, or other complex shapes. With an increase in gauge thicknesses of sheet metals the force required to bend increases.

Stamping: In the stamping process, a hydraulic or mechanical stamping press equipped with a tool and die is used to perform specific tasks like curling, drawing, embossing, flanging, etc

Hemming: Hemming is a process by which the edges of sheet metal are folded over itself or another piece of sheet metal to create a rounded edge. In the sheet metal fabrication process, two types of hemming processes are widely involved. They are roll hemming and conventional die hemming. Conventional hemming is used for mass production. A hemming roller is used for roll hemming.

Spinning: Spinning is a metal fabrication process where a lathe machine is used to rotate the sheet metal against a tool to produce conical or cylindrical shapes.

Sheet metal fabrication: Assembly

Assembly is basically joining sheet metal components produced using above mentioned cutting or bending processes. The common sheet metal assembly process consists of joining by Welding and joining using fasteners.

Welding: In the welding process, sheet metal components are joined together by melting sections with the application of heat to form a solid connection. There are various processes available that are used to weld sheet metals.

Joining using Fasteners: Similar or dissimilar sheet metal parts can easily be joined using fasteners like bolts, screws, rivets, etc.

Brazing: Brazing is a process similar to welding that operates by melting a filler without melting the sheet metals.

Adhesives: Adhesives can be used to hold metal sheets together in conjunction with other joining methods

Advantages and Disadvantages of Sheet Metal Fabrication

As sheet metal fabrication covers a wide area of techniques and methods, the advantages and limitations will vary depending on the process used during fabrication.

Benefits:

i. Sheet metal fabrication is fast and can produce high-quality components.

i. A large number of processes are available with wide range of materials

ii. High strength to weight ratio for sheet metal fabricated parts.

Disadvantage:

i. Each fabrication process has their own limitations.

ii. High initial cost for set up of equipment and tools.

iii. Requirement of skilled labors for each process.
