Product Overview
This is a high-efficiency 1*4 cavity precision injection mold specially designed for mass production of PC electrical switch plates, outlet panels and plastic housings. Adopting a mature large sprue + horn gate runner system, the mold provides smooth filling, balanced flow and clean automatic gate breaking for high-viscosity PC material. The entire mold structure adopts premium 1.2083ESR stainless mold steel with vacuum heat treatment hardness of HRC 48-52. The cavity is finely polished for glossy product appearance, while the core applies professional stoning finish to ensure perfect demolding, stable ejection and long mold service life. Ideal for high-volume, cost-effective production of standard household and commercial electrical wall plates.

Key Mold Advantages
1. 1×4 High-Efficiency Cavity Design
With four identical cavities in one mold, this tooling greatly improves daily production output and reduces unit manufacturing cost. The runner system is fully balanced to ensure consistent filling speed, pressure and cooling effect for every cavity. All finished switch plates and outlet panels maintain uniform size, weight and appearance quality, perfectly suitable for large-scale mass production orders.
2. Large Sprue & Horn Gate for Perfect PC Molding
PC material features high viscosity and is easy to produce flow marks and short shots during injection. The upgraded large sprue provides fast, stable and sufficient material feeding. The horn curved gate reduces melt shear force, avoids surface defects, and realizes automatic gate break during product ejection. No manual trimming is required, greatly improving production efficiency and keeping the product surface clean and flawless.
3. 1.2083ESR HRC48-52 Premium Mold Steel
Adopting ESR electroslag remelting refined 1.2083 steel, the mold has ultra-pure internal structure, high uniformity and excellent anti-rust and anti-corrosion performance. After vacuum heat treatment to HRC 48-52, the mold achieves high hardness, strong wear resistance and deformation resistance. It can withstand long-term continuous injection molding and maintain stable precision for a long time.
4. Cavity High Polish + Core Stoning Finish (Professional Matching)
This mold adopts a scientific dual surface treatment process: the product outer surface (cavity) is high-gloss polished to obtain a smooth, beautiful and high-grade panel appearance without scratches or orange peel. The inner core adopts stoning finish (fine grain stone polishing), which provides excellent demolding performance, prevents vacuum sticking, reduces ejection marks and protects mold texture during long-term mass production. This combination perfectly balances appearance quality and production stability.

FAQ
Q1: What is the benefit of core stoning finish?
A: Stoning finish on the core creates a fine uniform matte surface, which effectively increases demolding resistance, prevents vacuum sticking, reduces ejection marks, and improves production stability, while not affecting the outer high-gloss product appearance.
Q2: Why use horn gate for PC switch panel mold?
A: Horn gate provides smooth arc transition for high-viscosity PC melt, eliminates flow lines, and automatically breaks after molding. It requires no post-processing and keeps the panel surface perfect.
Q3: Is 1.2083ESR steel good for high-gloss PC parts?
A: Yes. 1.2083ESR is the best steel for high-gloss electrical plastic parts. It has fewer impurities, excellent polishing ability and strong rust resistance to keep stable gloss for long-term production.
Q4: How many shots can this mold reach?
A: With standard maintenance, the mold can reach 500,000+ shots with stable precision and surface quality.
Q5: Can you customize panel size and logo?
A: Yes, we provide full customization for panel shape, size, hole position, logo engraving and structural modification.
