Precision-Ground Mold Locating Pins | ±0.01mm Tolerance CNC Machined Parts

Product Overview

CNC High Precision Machined Mold Locating Pins are critical alignment components used in injection mould systems to ensure accurate positioning between mould plates and inserts. Manufactured by Senlan Precision, these locating pins are produced strictly on a Built-to-Print (OEM) basis, with controlled tolerances down to ±0.01 mm, supporting stable mould alignment and repeatable production performance.

Key Features & Advantages

• CNC-machined locating pins with ±0.01 mm dimensional tolerance

• Stable positioning for mould plates, cavities, and core assemblies

• Consistent fit to reduce mould wear and misalignment risk

• Suitable for single-cavity and multi-cavity mould systems

• Material, hardness, and surface finish customized per drawing

• Designed for long service life under repetitive mould cycles

Applications / Industry Use

• Injection mould locating and alignment systems

• Packaging moulds for bottles and caps

• Multi-cavity moulds for daily packaging products

• Medical consumable injection moulds

• Precision mould bases and tooling assemblies

Mould Structure & Design Description

Mold locating pins play a fundamental role in maintaining positional accuracy between moving and fixed mould halves. Improper alignment can lead to uneven cavity wear, flash formation, and shortened mould life.

Senlan Precision manufactures locating pins with attention to:

• Concentricity and straightness for precise alignment

• Controlled fit with bushings and mould plates

• Stable performance under repeated opening and closing cycles

• Compatibility with standard and non-standard mould base designs

All parts are manufactured strictly according to customer-supplied drawings and technical specifications.

Manufacturing Capability & CNC Machining

Locating pins are produced through a controlled CNC machining workflow, including:

• CNC turning and milling for structural accuracy

• Precision grinding for tight tolerance control

• Optional heat treatment for strength and wear resistance

• Final inspection using calibrated measuring equipment

Production is supported by high-precision equipment from MAKINO and HARDINGE, ensuring repeatability suitable for export-grade mould tooling.
