금형 인서트에서 완벽한 평행성을 달성하는 방법

In precision mold manufacturing, it’s very critical to achieve perfect perfect parallelism on mold inserts. Even a minor deviation in mold insert parallelism can lead to uneven wear, flashing, unstable part quality, and reduced tool life. To be fair, parallelism and dimensional accuracy are equally important.

Therefore, we will explain how to achieve parallelism on mold inserts through proper process selection, with a focus on PG grinding for mold inserts in this article.

Why Parallelism on Mold Inserts Is Critical

Based on the past experience, many mold failures not only because dimensions are out of tolerance, but also because parallelism control in mold manufacturing was overlooked.

Common Causes of Mold Insert Parallelism Errors

Before selecting the machining process, let’s understand the root causes of insert parallelism first

Why We Choose PG Grinding for Mold Insert Parallelism

PG grinding for mold inserts is a popular choice when tight parallelism is needed.

With proper setup, PG grinding can consistently achieve parallelism within ±0.001–0.002 mm. It is ideal for high precision grinding services.

Steps to Achieve Perfect Parallelism on Mold Inserts

Inspection and Parallelism Verification

PG Grinding vs WEDM for Mold Insert Parallelism

Process	Parallelism Capability	Typical Application
PG 그라인딩	±0.001–0.002 mm	High-precision mold inserts
WEDM	±0.003–0.005 mm	Complex profiles
CNC Milling	Limited	Pre-machining only

When comparing PG grinding vs WEDM for mold inserts, PG grinding offers superior parallelism and surface stability for critical components.

Conclusion

Therefore, to achieving perfect parallelism on mold inserts, only accurate machines is far from enough. It also requires the right process, correct datum strategy, and experienced execution. Among numerous options, PG grinding remains the most reliable solution for precision mold inserts made from hardened tool steel

Professional precision grinding services can help reduce manufacturing risk, improves mold performance and extends tool life.
