WHY DESIGN TOLERANCE MATTERS?
Exceeding M1 Class: While the industry standard ISO 3302-1 Class M1 is often the limit for others, it is our baseline. We specialize in high-precision molding where others fail.
Shrinkage Control: Our In-house Tooling compensates for material contraction at the micron level, ensuring the final part matches your STEP file perfectly.
Structural Integrity: Using Vacuum Compression Technology, we ensure that even at 0.2 mm, the material density is uniform and free of micro-bubbles.
