3 Reasons Why Mold Alignment Pins Are Critical to Your Tooling Performance

In the world of injection molding, alignment pins may seem like a minor component—but they play a major role in ensuring precision. Without proper mold alignment, you risk flash, parting line mismatch, and premature wear on your tooling.

At Dongxinda, we use hardened steel guide pins and bushings to maintain precise mold registration under high pressure. This ensures:

• Consistent part quality

• Reduced risk of flashing

• Longer mold life and fewer breakdowns

Whether you're running a single-cavity or high-output multi-cavity mold, mold alignment matters.

FAQs:

• Can worn alignment pins be replaced?
  Yes, our mold bases are designed for easy maintenance and pin replacement.

• Do you use standard or custom alignment systems?
  Both. We use DME, HASCO, or custom-built pins depending on customer needs.

• How do you check alignment during sampling?
  We inspect contact points, cycle wear, and molded part quality after every mold trial.
