Core Design & Performance Advantages

Advantage	Detailed Description
High Production Efficiency	1-out-4 cavity symmetrical structure ensures balanced filling in each cavity, greatly improving output and reducing unit production cost.
Hot Runner Material Saving	4-point hot runner design eliminates cold runner waste, shortens molding cycle, and avoids POM material degradation.
Superior Steel Durability	S7 steel with HRC54-56 high hardness provides excellent wear resistance and thermal stability, perfectly resisting long-term friction from POM high-crystallinity molding.
Uniform VDI24 Surface	Standard VDI24 matte texture realizes consistent anti-glare surface, covers minor flow marks, and meets industrial functional part appearance requirements.
POM Professional Optimization	Optimized cooling, venting and filling balance effectively solves POM common defects: shrinkage, voids, warpage and uneven size.

Application Scope

This precision POM injection mold is widely used for producing high-precision functional parts, including automotive mechanical accessories, electronic insulating components, industrial plastic fasteners, household appliance structural parts, and low-friction mechanical moving parts.

Conclusion

Equipped with 1*4 high-efficiency cavity, 4-point hot runner system, high-hardness S7 steel and standard VDI24 finish, this mold is a professional customized solution for stable and high-volume POM part production. It balances high efficiency, low cost, durable service life and perfect surface quality, which is ideal for industrial precision plastic mass production.
