Product Overview
This 1×4 cavity plastic industrial part injection mold is professionally engineered for high-volume, high-precision production of POM industrial components. Equipped with a 4‑points hot runner system, the mold ensures stable, balanced melt flow, zero runner waste, and consistent part quality across all four cavities. The core and cavity are made from S7 tool steel precisely heat‑treated to HRC54–56, delivering exceptional wear resistance, stability, and long service life for continuous POM molding. The mold cavity features VDI24 standard texture for a uniform matte surface that hides flow lines and improves part appearance.
Fully manufactured under ISO9001 quality management system, this mold integrates optimized cooling, reliable ejection, and robust structural design to minimize shrinkage, warpage, and short shots common in POM processing. It is widely used for gears, bearings, fasteners, structural supports, and various precision industrial plastic parts.

Core Advantages
1. 1×4 Cavity + 4-Points Hot Runner
Balanced 4‑points hot feeding ensures synchronized filling of all four cavities, improving dimensional consistency, reducing cycle time, and eliminating cold runner scrap. Ideal for high‑efficiency mass production of POM industrial parts.
2. S7 Steel HRC54–56 High Hardness
S7 tool steel with HRC54–56 hardness provides outstanding toughness, wear resistance, and anti‑deformation performance. It withstands long‑term high‑frequency POM molding, maintains precision, and extends mold life.
3. VDI24 Mold Finish
VDI24 texture creates a uniform, fine matte surface on POM parts, enhances wear resistance, covers minor molding marks, and improves assembly performance and appearance stability.
4. ISO9001 Full‑Process Quality Control
Every step from design, CNC machining, EDM, polishing, to assembly and testing follows strict ISO9001 standards. Stable dimension, reliable structure, low defect rate, and consistent batch quality.
5. Optimized for POM Molding
Targeted runner design, cooling layout, and ejection system effectively control POM shrinkage and warpage, ensuring straightness, roundness, and structural stability of industrial parts.
Applications
This mold is widely used to produce high‑performance POM components for industrial equipment, automotive systems, home appliances, power tools, office machinery, transmission mechanisms, and precision assembly parts.
FAQ
Q1: Why use 4‑points hot runner for this 1×4 POM mold?
A1: 4‑points hot runner provides independent, balanced feeding for each cavity, ensures stable filling, eliminates runner waste, shortens cycle time, and improves consistency of POM parts.
Q2: Why choose S7 steel HRC54–56 for POM industrial molds?
A2: S7 steel offers high hardness, toughness, and wear resistance. HRC54–56 enhances durability against POM friction and long production runs, maintaining precision and extending mold life.
Q3: What is the effect of VDI24 finish on POM parts?
A3: VDI24 provides a standard matte texture that improves surface quality, hides flow lines, reduces gloss, enhances grip and wear performance for industrial parts.
Q4: Is this mold certified under ISO9001?
A4: Yes. Design, processing, assembly, and testing are fully controlled under ISO9001 quality system to ensure stability, reliability, and repeatable precision.
Q5: Can this mold be customized for different part structures or materials?
A5: Yes. We can customize cavity shape, gate position, hot runner layout, steel type, hardness, and surface texture based on your 2D/3D drawings or samples.
Q6: Does this mold support long‑term mass production?
A6: Yes. S7 steel HRC54–56, robust structure, and ISO9001 quality control make it ideal for millions of shots in stable mass production.
Q7: Can we adjust the number of cavities?
A7: Yes. We can modify the mold to 1×1, 1×2, 1×8, or other cavity layouts based on your production volume and cost requirements.
