Designing Your Product
Starting with an idea, an outline drawing or concept 3D Model, we can quickly provide detailed drawings and diagrams that will help you finalise your design requirements.
We use Solidworks™ software to enable you to visualise the final product. There are some design guidelines that need to be considered.
Investment Casting Design Considerations
There are several key points that we need to consider to ensure that we can deliver your finalised product on time and within budget.
We have listed some of the more important aspects below:
Keep casting sections to a uniform thickness and avoid several sections meeting at one point
We do not require draft angles
Avoid heavy isolated sections
Avoid sharp internal corners; a small radius of 0.5mm is preferred
Most holes can be cast at clearance, reaming or tapping sizes
Specify all numbering, logos and lettering required and whether embossed or de-bossed is required. Embossed within a sunken recess is generally preferable
Indicate the machining allowance, if required
Casting feed pads should normally be placed at the heaviest section, in a flat area for ease of removal
Avoid deep narrow blind channels or pockets if possible
Select a suitable alloy from the standard alloy ranges cast
Section sizes of less than 1.0mm can be cast locally, with sections > 1.5mm preferable
Below is a table with our cast hole preferences:
|Maximum length of hole||Diameter of hole (d)|
|Through Holes||2.5 - 5.5mm||≤ 1.5 d|
|5.5 - 10mm||≤ 2.8 d|
|> 10mm||≤ 5.0 d|
|Blind Holes||3 - 5mm||≤ 1.0 d|
|5 - 15mm||≤ 2.0 d|
|> 15mm||≤ 3.0 d|
Note: Features that exceed these design constraints can be cast utilising preformed ceramic cores.
