Miller™ Calibration & Chain Carbide Balls
Precision Calibration Solutions for Plastic & Tank Processing Equipment
Miller Carbide supplies high‑precision coated cemented carbide calibration balls and chain ball assemblies designed for industrial calibration, sizing, and inspection systems. Our products are widely used in plastic tank manufacturing, pipe calibration, and rotational molding equipment, where long service life and dimensional stability are critical.
Product Overview
Our Calibration Balls and Chain Ball Systems are engineered for demanding environments involving heat, abrasion, and filled plastics. Manufactured from tungsten carbide (WC) and available with advanced wear‑resistant coatings, these components ensure consistent internal diameter calibration and repeatable measurement results.
Typical applications include:
- Internal diameter calibration of plastic tanks and pipes
- GO / NO‑GO dimensional inspection systems
- Chain‑driven calibration fixtures
- Engineering fixtures and custom calibration tools

Application – Tube Bending Ovality Reduction Calibration
After tube bending operations, ovality deformation often occurs due to material stress and bending forces.
Tungsten carbide calibration balls are used as internal calibration tools to reduce ovality and restore roundness.
Custom Manufacturing
Miller Carbide supports custom designs based on drawings or samples, including:
- Special diameters and tolerances
- Coated or uncoated carbide solutions
- Complete chain ball or fixture assemblies
Our engineering team works closely with customers to deliver reliable calibration components tailored to specific equipment requirements.
