Complete Project Engineering : Aluminium Sand Casting



Robust Engineering Australia is proud to introduce it's new Aluminium Sand Casting Design & Manufacturing Project Management Services within Melbourne, Victoria, Australia.
We are using our own state of the art Pro engineer CAD/CAE design software. We have used this software to produce several hundred quality casting components over the last 7 years, designing and delivering the product within record time and within the allocated budget.
We can produce the same casting design services for your future projects in a cost effective manner within your time and budget.
We guarantee you the best outcome through our efficient design services and high expertise with Pro engineer CAD systems. Our competitive prices and timely delivery of solutions will assist you to win business over your competitiors. We fully guarantee to deliver your design within the agreed time frame. To find out more about our guarantee, please contact Lucky through 

 lucky@robust-engineering.com.au




Our service includes :

  • 3D Casting Engineering Modelling & 2D Drafting Services.
  • 3D Pattern Designs and CNC Tool Path assistance.
  • Design Jig & Fixtures and 2D drafting.
  • Complete Tooling guidance throughout to manufacture your cost effective casting patterns.
  • Precision Casting and Assistance to Manufacture your Final Machining Component.

Since 2002, we have been working with leading engineering companies who design and manufacture automotive components all around the world. We assist them to develop 3D design modelling; casting pattern designs manufacturing; and jig & fixture design drafting.
A signifciant number of projects involved high level 3 - 5 Axis CNC manufacturing tool paths for it's component manufacturing.

We successfully project managed and produced several hundred quality Aluminium, Nodular Iron casting through an Australian company within record time frames and budget. We serviced
companies within Automotive, Industrial, defence and motorsport.


As we have started a new venture in Northern region of Melbourne, Victoria, Australia to serve Australian companies. We will work directly with you and project manage your design project, utilizing our strong connections with leading chineese Aluminium casting technologies. We can also do the same to manufacture your precision casting part through leading CNC manufacturers, who specialise in casting technologies and precision CNC manufacturing.

Making a New Plastic Product


End of this Session, I will take you to the level where you will have 100% knowleadge to design your own plastic product.



How does a designer begin to make the new or redesigned product?

First of all, the designer must decide which type of plastic to use for his product?

Secondly he must select the best method for [processing the plastic to create the finished product.

Step 1:

Choosing the proper plastic.

There are so many plastics, each with specific chemicals and physical properties which will effect the performance of the product. There can be vast differences in processing these plastics.

There are two basic types of plastics Thermosets and thermoplastics.
Engineering Plastic materials

Selecting the Best Processing Method.

Thermoforming
Rotational molding
Structural form molding
Extruding
Extrusion blowing( Blow molding)
Injection Blow molding
Stretch blowing
Compression molding
Transfer molding
Injection moulding
Injection-Compression molding
Reaction- Injection moulding
Expandable bead molding
Lost-core molding

Not all plastics are suitable for this process.

Advantages and Disadvantages of the above methods.


Processing under this category includes compression, transfer or Injection molding of thermosets or thermoplastics

  • Advantages: Suitable for any size product from those weighing fractions of a gram to large
  • pallets and containers weighing 40kg and more.
  • Excellent surface definition
  • Good accuracy
  • Good repetitiveness
  • High Productivity
  • Product finishing usually is not required after molding
Disadvantage:

High Mold and machine cost

We are only going to focus Injection and Blow moulding process in this blog, however we should consider some of the other Plastic processing methods which is available to use.

Extruding:

Engineering Design Analysis

FEA analysis in



Pro Engineer /Mechanica



We make consistent reference throughout this blog to engineering judgement and wisdom. Some of this wisdom is acquired through years of practice in the design profession, but much of it is gained through close association with my inspired and creative business directors.

Engineering design is an engineering discipline.

  • Design Against Failure

    Engineers/Designers use materials, whose properties they do not properly understand, to form them into shapes, whose geometries they cannot properly analyse, to resist forces they cannot properly assess, in such a way that the public at large has no reason to suspect the extent of their ignorance. John Ure Engineer 1998.


One of the real problems we shall face in this area is that of relating the strength of an element to the external loads which are imposed upon it. These external loads cause internal stresses in the element. In this analysis we shall concern ourselves with the determination of these stresses.

We will introduce the concept of strength and begin the process of relating strength and stress to achieve safety.It is worth observing that the stresses which are calculated are only as reliable as are the external loads and geometries which are used in the determination. Once a product has been manufactured and placed in the hands of the consumer, the manufacturer has no control over that product and , to some extent, over external loads to which it may be subjected.

It is for this reason, among others, that testing and experimental proving are so important in the design and development of any Product development.
