Product Overview
This is a high-efficiency, high-precision 1*4 cavity injection mold specially developed for mass production of PC electrical equipment control board housings. Designed with a large sprue and horn gate gating system, this mold ensures smooth, balanced and residue-free filling for high-viscosity PC material. The mold adopts imported 1.2083ESR high-purity stainless mold steel with vacuum heat-treated hardness of HRC 48-52. The cavity is finely polished for neat outer surface quality, while the core adopts professional oil stone finish to achieve excellent demolding performance and stable long-term production. Suitable for mass manufacturing of electrical control shells, circuit board housings and electrical panel covers with strict dimensional and appearance requirements.

Core Advantages
1. 1×4 High Production Efficiency
Four-cavity balanced layout greatly improves output and reduces unit production cost. All cavities run synchronously with consistent pressure, temperature and filling volume, ensuring uniform size, flatness and assembly precision of every PC control housing. Perfect for large-volume industrial electrical part orders.
2. Large Sprue & Horn Gate for PC Material
PC material has high melt viscosity and is prone to flow marks and short shots. The large sprue provides stable and fast material supply, while the smooth arc horn gate reduces shear lines and filling defects. The gate breaks automatically during demolding, leaving no residual marks on the housing surface and eliminating manual trimming processes.
3. Premium 1.2083ESR Steel HRC48-52
1.2083ESR is ESR refined high-purity stainless steel with ultra-low impurities, excellent rust resistance and superior polishing performance. After vacuum heat treatment to HRC 48-52, the mold obtains high hardness, strong wear resistance and anti-deformation ability, maintaining long-term stable precision for electrical housing mass production.
4. Professional Core Oil Stone Finish
Different from full gloss molds, the core adopts oil stone finish (fine stoning surface). This treatment effectively prevents vacuum sticking, reduces ejection marks, improves demolding smoothness and avoids product deformation. It greatly stabilizes continuous injection molding while keeping the outer cavity surface clean and beautiful.

FAQ
Q1: What is oil stone finish used for?A: Oil stone finish on the core creates a fine, uniform matte surface. It prevents vacuum sticking, improves demolding efficiency, reduces ejection marks and ensures stable continuous production.
Q2: Why use horn gate for PC housing?A: Horn gate offers smooth melt flow for high-viscosity PC, eliminates surface flow lines, and auto-cuts during demolding, saving labor and ensuring flawless housing appearance.
Q3: What is 1.2083ESR steel advantage?A: 1.2083ESR has higher purity, better anti-rust performance and finer polishing effect than ordinary steel, ideal for long-term production of high-quality electrical plastic parts.
Q4: Can you customize the control housing size and structure?A: Yes, we provide full customization according to customer drawings, samples and technical requirements.
