Cast Blank Single-Pitch Helical Flight

Product Overview

Jiahe Conveying's Cast Blank Single-Pitch Helical Flight is a precision-cast conveying component designed for heavy-duty industrial applications. Manufactured through advanced foundry processes, these cast blank flights provide superior structural integrity and excellent wear resistance as the base material for final machining operations.

Technical Specifications

Manufacturing Process

1. Precision Casting

• Sand casting with resin-bonded molds

• Investment casting for complex geometries

• Lost foam casting for large components

2. Material Properties

• High-Cr White Iron: 550-700 BHN hardness

• Ni-Hard IV: Excellent impact-abrasion resistance

• Duplex Steel: Superior corrosion resistance

3. Quality Control

• X-ray inspection for internal defects

• Spectrometer analysis for composition

• Dimensional verification with 3D scanning

• Hardness testing across multiple points

Design Features

1. Single-Pitch Consistency

• Uniform pitch throughout flight length

• Precise helix angle maintenance

• Optimized for consistent material flow

2. Machining Allowance

• 3-5mm excess material on critical surfaces

• Pre-machined reference surfaces

• Balanced weight distribution

3. Structural Integrity

• Reinforced flight root design

• Gradual thickness transitions

• Stress-relieved construction
