Mould Structure & Design Description

Injection molding pins are critical functional elements used to form internal features, channels, and fine details within plastic mould cavities.
For cosmetic mould applications, key design considerations include:

• Pin concentricity and straightness

• Surface smoothness to prevent flow marks

• Accurate fit with core and cavity components

• Resistance to corrosion and wear from resin additives

Each pin is manufactured according to the specific mould structure and cavity layout provided by the customer.

Frequently Asked Questions (FAQ)

Q1: Do you offer standard injection molding pins?
No. All molding pins are custom manufactured based on customer drawings or specifications.

Q2: Is EDM processing necessary for all pins?
EDM is applied when complex geometry, sharp internal features, or high precision is required.

Q3: Can these parts be used in multi-cavity moulds?
Yes. They are designed for dimensional consistency across high-cavity mould systems.

Q4: Can surface finishing be customized?
Yes. Polishing, lapping, and surface treatments can be applied based on mould requirements.
