Sprue Rings

Overview

A sprue ring—also sometimes called a register ring—is a critical alignment component in injection molding. Positioned between the molding machine and the mold, it ensures precise positioning of the mold relative to the injection unit. Typically crafted from hardened, medium-carbon steel, sprue rings help maintain consistent interface alignment and reliable operation cycle after cycle.

Sprue Rings

Key Features

Precise Alignment & Registration
Ensures the mold’s center line aligns perfectly with the injection unit, reducing misalignment and premature wear.
Durable, Hardened Construction
Made from case-hardened medium carbon steel (CHMCS), sprue rings can withstand repetitive stress while maintaining accurate positioning.
Robust Support for Mold Integrity
By holding the mold in the correct position, they reduce strain on the sprue bushing and prevent damage during injection and ejection cycles.
Facilitates Efficient Mold Changes
Acts as a durable interface that streamlines mold installation and removal, supporting faster tool changes and improved production uptime.
Universal Compatibility
Designed to fit standardized base plate configurations, sprue rings support a wide variety of molds and molding machines, making them highly versatile.
