Precision DLC Coated Core Pins & Inserts | Durable Hasco Standard Tooling Parts

Product Overview

Senlan Precision manufactures Hasco-standard DLC coated core inserts for injection mold core plates, designed for high-cycle, multi-cavity injection molding applications. Produced strictly on a Built-to-Print (OEM) basis, these inserts combine precise dimensional control with low-friction DLC surface treatment to improve wear resistance, reduce sticking, and ensure stable long-term mold performance.

Key Features & Technical Advantages

• Manufactured according to HASCO standard dimensions

• DLC (Diamond-Like Carbon) coating for reduced friction and wear

• Improved demolding performance and reduced plastic adhesion

• High surface hardness with minimal impact on core dimensional accuracy

• Suitable for high-speed, high-cavity injection molding

• Consistent repeatability for mold maintenance and replacement

Application Scenarios / Industry Applications

• Injection mold core plates for packaging components

• Bottle caps, closures, and sealing part molds

• Multi-cavity molds with frequent opening and closing cycles

• High-volume injection tooling requiring low wear and stable surfaces

• Mold refurbishment and standardized spare part replacement

Mold Structure & Design Description

The DLC coated core insert is mounted within the injection mold core plate and directly forms the internal geometry of molded parts. The HASCO-standard interface ensures reliable interchangeability, while the DLC coating minimizes surface friction, reduces galling, and improves resistance to abrasion caused by reinforced or filled plastics. All dimensions, tolerances, and coating specifications follow customer drawings or HASCO standards.

FAQ – Technical & Procurement

Q1: What is the benefit of DLC coating on core inserts?
DLC coating reduces friction, improves wear resistance, and minimizes plastic sticking during demolding.

Q2: Do you manufacture strictly to HASCO standards?
Yes. Inserts can be produced to HASCO standard dimensions or customer-specific drawings.

Q3: Is OEM customization supported?
Yes. All parts are manufactured on a Built-to-Print (OEM) basis.

Q4: What tolerances can be achieved after DLC coating?
Dimensional deviations are tightly controlled, typically within ±0.003–0.01 mm depending on part size.

Q5: Are these inserts suitable for multi-cavity molds?
Yes. They are commonly used in high-cavity and high-output injection molds.
