Core Design & Technical Advantages
1. 1×4 High-Efficiency Multi-Cavity Structure
Equipped with four balanced cavities, the mold quadruples production output compared with single-cavity molds. The internal runner layout is scientifically balanced to ensure consistent injection pressure, filling speed and cooling effect for each cavity. All finished housing shells feature uniform wall thickness, stable size and consistent appearance, effectively reducing unit production cost and fully meeting large-batch industrial production demands.
2. Direct Gate + Horn Runner System
Combined with direct gate and smooth horn runner structure, this mold solves the common filling problems of thick and thin-wall housing parts. The horn runner reduces melt shear resistance, makes plastic fluid flow smoother, and effectively avoids short shots, shrinkage, flow lines and weld marks. The direct gating design ensures fast feeding and high molding efficiency, suitable for continuous high-speed production of equipment shell parts.
3. Premium 1.2083ESR HRC48-52 Mold Steel
Adopting ESR electroslag remelting refined 1.2083 steel, the material features ultra-pure texture, fewer internal impurities and excellent anti-rust and anti-corrosion performance. After strict vacuum heat treatment, the hardness reaches HRC 48-52, providing outstanding wear resistance, compression resistance and deformation resistance. It can maintain long-term mold precision and surface stability during continuous mass production, greatly reducing mold maintenance frequency.
4. Scientific Semi-Polish Core Design
The core adopts standard semi-polish finish, which is the most suitable surface treatment for equipment shell molds. The moderate matte surface effectively prevents vacuum sticking and ejection deformation during demolding, improves production stability and reduces defective products. Meanwhile, the fine polished cavity ensures neat and smooth outer surface of the housing, perfectly balancing production efficiency and product appearance quality.

FAQ
Q1: What are the advantages of direct gate with horn runner?A: The horn runner optimizes melt flow path to reduce flow resistance, while direct gate ensures fast feeding. This combination eliminates surface flow marks and short shots, improving molding speed and product qualification rate for equipment shells.
Q2: Why adopt semi-polish core for housing mold?A: Semi-polish core provides proper surface roughness for smooth demolding, prevents product sticking and deformation during mass production, and greatly stabilizes continuous production efficiency.
Q3: What is the advantage of 1.2083ESR steel?A: 1.2083ESR is high-purity stainless mold steel with excellent anti-rust performance, uniform hardness and good processing stability, supporting long-term high-precision mass production.
Q4: Do you support custom housing molds?A: Yes. We support full customization of shell shape, size, hole position, structure and surface finish according to customer drawings or samples.
