1*4 Cavity POM Material Hot Runner 2344 HRC48-52 Mold Steel SPI-B2 Finish Cavity And Core Double Worm Custom Mold

Product Overview

High-efficiency 1×4 cavity custom mold for POM double worm plastic parts. Equipped with hot runner system, 2344 HRC48-52 mold steel, and SPI-B2 cavity & core finish. Optimized for precision, wear resistance, and mass production of worm gears in power transmission applications.

Key Features

✅ 1×4 Cavity High Output

Four identical double worms per cycle; balanced runner for consistent quality, high efficiency.

✅ Hot Runner System

Eliminates cold runner waste, shortens cycle time, ensures uniform filling for complex worm profiles.

✅ 2344 HRC48-52 Mold Steel

Hardened hot-work steel, high hardness/toughness/wear resistance; long life ≥1,000,000 cycles, maintains precise worm teeth.

✅ SPI-B2 Cavity & Core Finish

Fine matte texture on both cavity and core; low friction, good release, consistent appearance.

✅ Double Worm Precision Design

Accurate tooth profile, tight tolerance, optimized cooling/venting; prevents warpage, ensures smooth meshing.
