CONSISTENT PART REPLICATION

Vacuum casting helps you make every part the same. You get the same size, shape, and surface each time. This is important for medical devices that must meet strict rules. You can trust that each prototype will match your design.

POST PROCESSING AND FINISHING

After you take the part out of the mold, you need to finish it. This step makes your prototype look and work like a real product.

PAINTING POLISHING AND TEXTURING

You check the part for any extra bits. You can use sandpaper to make it smooth. Sometimes, you need to cure the part again to make it stronger. You can polish and paint the part to get the look you want. You can also add texture for better grip or style.

FUNCTIONAL TESTING PREPARATION

You get your prototype ready for testing. You check if it fits, looks good, and works right. This helps you make sure your medical device works as it should. You can use your prototype to test your design before making lots of them.
