Product Overview
This is a high-efficiency 1*4 cavity injection mold purpose-built for mass production of PC electronic control panel housings. Featuring a sub gate (submarine gate) system, it delivers clean, invisible gating marks on finished parts. Constructed from premium 1.2083ESR mold steel with heat-treated hardness of HRC 48-52, this tooling offers excellent wear resistance, anti-rust performance, and long-term dimensional stability. Optimized for PC material, the mold balances high-volume production efficiency with the precision and surface quality required for electronic control panel housings.

Core Advantages
1. 1×4 Multi-Cavity High Efficiency
The 1*4 balanced cavity layout quadruples production output per cycle, significantly reducing unit manufacturing costs. All four cavities feature identical runner distribution, injection pressure, and cooling rates, ensuring every control panel housing has consistent size, wall thickness, and appearance quality. This design is ideal for large-scale orders of standardized electronic components.
2. Sub Gate System for Flawless Appearance
Invisible Gating: The submarine gate automatically breaks during ejection, leaving no visible marks on the housing surface, eliminating the need for manual trimming.
Balanced Flow: The optimized runner path ensures uniform melt distribution across all four cavities, preventing flow marks, weld lines, and short shots in complex housing geometries.
3. Premium 1.2083ESR Mold Steel
Made from ESR-refined 1.2083 stainless steel, this mold offers ultra-pure internal texture, superior anti-corrosion properties, and excellent polishing performance. After vacuum heat treatment to HRC 48-52, it delivers exceptional wear resistance and deformation resistance, maintaining stable precision and surface quality over hundreds of thousands of production cycles.
4. Optimized Surface Treatment for PC Parts
The cavity is finely polished to a smooth finish, while the core uses a semi-polished treatment. This combination prevents vacuum sticking during demolding, reduces ejection marks, and ensures both the outer appearance and internal assembly features of the control panel housing meet strict quality standards.

FAQ
Q1: What are the benefits of using a sub gate for control panel housings?
A: Sub gates automatically separate from the product during demolding, leaving no visible marks on the surface. This eliminates manual trimming, improves production efficiency, and maintains the housing’s clean appearance.
Q2: Why is 1.2083ESR steel ideal for this mold?
A: 1.2083ESR is ESR-refined high-purity stainless steel with superior anti-rust performance and polishing capabilities. It maintains consistent hardness and precision during long-term production, making it perfect for high-quality PC electronic parts.
Q3: Can this mold produce transparent or colored PC housings?
A: Yes. The polished cavity and optimized sub gate system eliminate weld lines and flow marks, supporting production of transparent, translucent, and solid-color PC control panel housings.
Q4: Is custom modification available for the housing design?
A: Absolutely. We support full customization of housing shape, size, hole positions, mounting features, and surface textures based on your drawings or samples.
