💡 Tip:
The following mold design steps are a simplified version, intended as a general reference.
In practice, different 3D modeling or CAD software (such as SolidWorks, Fusion 360, Creo, etc.) may have variations in feature names, user interfaces, or command locations. Please adjust accordingly based on the software you are using—the overall design logic and workflow remain the same.
Mold Design Process
Step 1: Model or Import the Product
Start by creating or importing the 3D model of the product you want to mold.
Step 2: Create an Assembly with the Product
Use the product model to generate a new assembly file.
Step 3: Insert a New Part (Mold Block)
Insert the mold block (new part) into the assembly.
Step 4: Apply the Cavity Command
Use the cavity feature to “hollow out” the product shape from the mold block.
Step 5: Add Injection Gate and Venting Channels
- Injection Gate Position: Place at the highest point of the product or the geometric center’s highest point.
- Injection Gate Hole Spec: Ø10.3 mm, depth 5 mm
- Runner Hole Spec: Ø6–8 mm, depth 5 mm
- Venting Channel Position: Farthest point from injection gate, or raised features inside mold cavity
- Venting Channel Spec: 0.4 mm wide × 0.2 mm deep
Step 6: Split the Mold (Choose a Suitable Parting Line)
- Select the direction with the largest projected area as the mold opening direction.
- Use the center of the thickness direction as the parting surface for mold splitting.
Note: Since Saltgator mainly injects soft-gel materials, undercuts or draft differences less than 2 mm can generally be ignored without affecting demolding.
