What is an Extrusion Die


Extrusion dies are essentially thick, circular steel disks containing one or more openings to create the desired profile. They are normally constructed from H-13 die steel and heat-treated to withstand the pressure and heat of hot aluminum as it is pushed through the die.


While it may appear that aluminum is a very soft metal, the reality is it takes a tremendous amount of pressure to push a solid log (billet) of aluminum through a thin, multi-holed die to create the desired shape. In fact, it takes 100,000-125,000 psi of force to push a billet through an 8” inch press.


To put that force into context, a power washer to clean a car pushes out water at around 2,500 psi. Increasing that pressure to 5,000 psi can destroy the brick on a building. The pressure produced in an extrusion press is 20 times that amount.









What is Aluminum Die Casting ?


Hot chamber die casting can be used with aluminum, zinc, magnesium, and other low melting alloys using either our proprietary multi-slide or conventional tooling. 


The hot chamber machine contains the melting pot, while the cold chamber melt pot is separate and the molten metal has to be ladled into the shot sleeve. With the internal mechanism, it makes the hot chamber the faster of the two processes. Other advantages of the hot chamber process include reduced porosity and longer die life from utilizing alloys that do not erode or dissolve the machine when put under heat or high pressure.


The injection mechanism of a hot chamber machine is immersed in the molten metal. The furnace is attached to the machine by a metal feed system called a gooseneck.


The die is closed and the piston rises, opening the port, allowing molten metal to fill the cylinder.


Next, the plunger seals the port, pushing the molten metal through the gooseneck and nozzle into the die cavity where it is held under pressure until it solidifies.


The die opens and the cores, if any, retract. The casting remains in only one die half – the ejector side. The plunger then returns, allowing residual molten metal to flow back through the nozzle and gooseneck.





Ejector pins push the casting out of the ejector die. As the plunger uncovers the filling hole, molten metal flows through the inlet to refill the gooseneck.

Aluminum Anodized


Aluminium alloys are anodized to increase corrosion resistance and to allow dyeing (colouring), improved lubrication, or improved adhesion.









Powder Coating?


Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames.





(1) 冲压加工的生产效率高,且操作方便,易于实现机械化与自动化。这是因为冲压是依靠冲模冲压设备来完成加工,普通压力机的行程次数为每分钟可达几十次,高速压力要每分钟可达数百次甚至千次以上,而且每次冲压行程就可能得到一个冲件。
(2) 冲压时由于模具保证了冲压件的尺寸与形状精度,且一般不破坏冲压件的表面质量,而模具的寿命一般较长,所以冲压的质量稳定,互换性好,具有“一模一样”的特征。
(3) 冲压可加工出尺寸范围较大、形状较复杂的零件,如小到钟表的秒表,大到汽车纵梁、覆盖件等,加上冲压时材料的冷变形硬化效应,冲压的强度和刚度均较高。
(4) 冲压一般没有切屑碎料生成,材料的消耗较少,且不需其它加热设备,因而是一种省料,节能的加工方法。






Stamping Process


Die stamping is a cold forming process that takes a sheet of metal, referred to as a blank or tool steel, and cuts and shapes it using a single or series of dies to create a desired shape or profile. The force that is applied to the blank modifies and changes its geometry, which creates stress that makes the workpiece suitable for bending or shaping into complex forms. The parts produced can be exceptionally small or extremely large depending on the application.


The die stamping process, also known as pressing, includes a number of techniques such as punching, blanking, piercing, coining, and several other operations. Designs are required to be precise so that each punch produces optimal quality.


The dies in die stamping are specialized tools that have been customized to create a specific design, which can be very simple common items or complex computer components. Dies can be designed to perform a single function or be part of a series of functions that happen in stages.


Forming dies are:


  • -Bending
  • -Flanging
  • -Drawing
  • -Stretching
  • -Coining
  • -Ironing


Cutting dies are:

  • -Shearing
  • -Blanking
  • -Trimming
  • -Notching
  • -Piercing











Computer Numerical Control (CNC) machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.

When a CNC system is activated, the desired cuts are programmed into the software and dictated to corresponding tools and machinery, which carry out the dimensional tasks as specified, much like a robot. In CNC programming, the code generator within the numerical system will often assume mechanisms are flawless, despite the possibility of errors, which is greater whenever a CNC machine is directed to cut in more than one direction simultaneously.

What is Plastic injection molding do?


Plastic injection molding is known as the most common and most efficient form of molding. The process itself is extremely fast compared to other methods, and the high production output rate makes it even more efficient and cost-effective.

Speed depends on the complexity and size of the mold but only about 15-120 seconds pass between each cycle time. With the short period between cycles, a greater quantity of molds can be produced in a limited amount of time, thus increasing possible revenue and profit margins. At Rodon, we run parts 24/7 using an MRP system (Material Requirement Planning System).
