WHY CLIENTS COME TO US

Product Problems We Avoid:

When your injection molding provider cuts corners and doesn’t prioritize quality, you’ll notice a few problems:

Inconsistent parts – Variations in weight or dimensions between parts
Sink Marks – Small, visible depressions
Weld Lines – Surface imperfections and weak spots
Jetting – Increased resistance in the mold
Flow Lines – Off-color streaks or patterns that look unprofessional
Burn Marks – Dark discoloration
Warping – Bending or twisting out of shape during cooling

Our machines are designed for ultimate precision, making these all-too-common issues a thing of the past.
