Hardened 62 HRC Round Taper Interlocks | High-Precision Mold Positioning

Product Overview

The 62HRC Round Taper Interlock is a high-hardness mould alignment component manufactured in accordance with DME / DIN standards. It is designed to provide precise mould half positioning and long-term stability in injection mould systems. Senlan Precision supplies these interlocks strictly on a Built-to-Print basis, ensuring dimensional accuracy, repeatable alignment, and reliable performance in high-cycle and multi-cavity mould applications.

Key Features & Advantages

• Heat-treated hardness up to 62 HRC for extended service life

• Round taper design for accurate mould alignment and self-centering

• Manufactured to DME / DIN standard geometry or customer drawings

• Excellent wear resistance for high-cycle injection moulds

• Stable performance in multi-cavity and high-precision mould structures

• Custom dimensions and tolerances available (OEM / Built-to-Print)

Applications / Industry Use

• Plastic bottle cap and closure moulds

• Packaging moulds requiring precise parting-line alignment

• Medical consumable injection moulds

• Multi-cavity mould systems with tight alignment control

• High-speed injection moulding environments

Mould Structure & Design Description

Round taper interlocks are installed between the cavity side and core side of an injection mould to ensure accurate positioning during mould closing. The tapered geometry provides automatic centering while reducing lateral movement under injection pressure. High surface hardness and controlled tolerances help maintain mould accuracy and minimize wear over long production runs.

Manufacturing Capability & CNC Machining

Senlan Precision manufactures round taper interlocks using precision CNC machining combined with controlled heat treatment and finishing processes to achieve consistent hardness and dimensional stability.

Manufacturing processes include:

• CNC turning for taper accuracy and concentricity

• CNC milling for mounting features and positioning surfaces

• Heat treatment to achieve uniform 62HRC hardness

• Precision grinding for mating surface accuracy

• Dimensional and hardness inspection

Production is supported by advanced machining equipment, including Japanese MAKINO machining centers and U.S. HARDINGE precision turning machines, enabling stable tolerance control for mould-critical components.

FAQ – Technical & Purchasing

Q1: Are these interlocks fully compatible with DME / DIN standards?
Yes. Standard DME / DIN geometries can be produced, as well as custom variants based on customer drawings.

Q2: Can hardness be adjusted if 62HRC is not required?
Yes. Hardness levels can be customized according to application and service life requirements.

Q3: Do you stock standard sizes?
No. Senlan Precision focuses on Built-to-Print manufacturing rather than stock items.

Q4: Are these suitable for multi-cavity moulds?
Yes. They are commonly used in multi-cavity mould systems requiring precise and stable alignment.
