Custom Precision Mold Components | Through-Hardened 43-47 HRC Tooling Parts

Product Overview

Durable non-standard precision mould parts from Senlan Precision are manufactured for injection mold systems requiring controlled internal hardness and long-term dimensional stability. With an inside hardness range of 43–47 HRC, these components balance strength and toughness, making them suitable for continuous production environments. All parts are custom manufactured strictly according to customer drawings and technical specifications.

Core Features & Technical Advantages

• Built-to-Print manufacturing based on customer drawings

• Inside hardness controlled within 43–47 HRC

• Balanced wear resistance and internal toughness

• Stable performance under repeated injection cycles

• Suitable for non-standard and complex mould structures

• Consistent dimensional accuracy for interchangeable mould parts

Applications & Industry Use

These non-standard precision mould parts are widely used in:

• Plastic injection moulds for packaging components

• Bottle caps, closures, and dispensing system moulds

• Medical plastic moulds requiring stable core performance

• Multi-cavity mould systems with customized inserts

• High-volume production moulds with routine maintenance needs

All applications are limited to industrial packaging and medical-related injection molding.

Mold Structure & Design Description

Non-standard precision mould parts typically function as structural or forming elements within injection molds. Internal hardness plays a critical role in resisting deformation while maintaining sufficient toughness to avoid brittle failure.

Key design considerations include:

• Internal hardness distribution and heat treatment control

• Fit and alignment within the mould assembly

• Compatibility with cavity, core, or sliding structures

• Long-term dimensional stability under thermal cycling

• Ease of replacement in multi-cavity mould systems

Each component is engineered to integrate precisely into the customer’s mould design.
