Product Description

This is a high-precision 1×4 multi-cavity injection mold engineered for mass production of PP plastic components. Built with premium S136 stainless steel hardened to HRC48-50, it features a combined edge gate and tunnel gate system for versatile molding options, a precision-finished core, and a VDI 24# surface finish to deliver consistent, high-quality parts for a wide range of industrial and consumer applications.

Key Features

✅ 1×4 Multi-Cavity Design

Four identical cavities ensure balanced material flow, uniform part quality, and high production efficiency, significantly reducing unit cost for large-scale PP component manufacturing.

✅ Dual Gate System: Edge Gate + Tunnel Gate

The mold is equipped with both edge gate and tunnel gate configurations, offering flexible solutions for different part designs. The tunnel gate allows automatic gate break during ejection, eliminating manual trimming and leaving minimal visible marks, while the edge gate ensures stable filling for complex geometries.

✅ S136 Mold Steel (HRC48-50)

Made of high-grade S136 stainless steel with a hardness of HRC48-50, this mold provides exceptional corrosion resistance, excellent polishability, and superior wear resistance. It ensures long mold life (over 500,000 shots) and consistent performance, even with repeated injection cycles for PP material.

✅ Precision Finished Core Mold

The core mold is carefully finished to meet strict dimensional tolerances, ensuring accurate replication of complex part features such as ribs, bosses, and mounting holes. This guarantees the PP components meet all functional and assembly requirements.

✅ VDI 24# Mold Finish

The mold cavity is finished to VDI 24# standard, producing a uniform, fine-textured surface on the PP parts. This finish balances aesthetic appeal with practicality, providing a smooth yet non-slip surface that is ideal for various plastic components.

✅ Optimized for PP Material

Tailored for polypropylene molding, the mold features optimized flow paths, cooling channels, and venting systems to prevent common defects such as warpage, shrinkage, sink marks, and flow lines, ensuring consistent quality across every shot.
