Product Overview
This custom injection mold is professionally developed for manufacturing ABS charger base plastic parts, widely applied in power adapters, mobile chargers, small home appliance power bases and other electronic plastic components. Adopting a practical 1+1 cavity structure, the mold realizes dual functions of sample trial production and mass production, which is more flexible and cost-effective than traditional single-cavity or multi-cavity molds.
The mold is built with high-standard 738H pre-hardened mold steel with hardness reaching HRC 35-40, ensuring stable mold structure, strong compression resistance and long service life. Matched with a large sprue horn feeding system, it solves the filling difficulty of thick electronic plastic parts, guarantees uniform melt flow and stable mold filling. The entire cavity surface adopts standard VDI 24 fine texture, presenting a delicate matte surface for finished charger bases, compliant with the appearance requirements of consumer electronic products. All mold structures are optimized for ABS material characteristics to effectively control product warpage, size deviation and surface defects.

Core Advantages
1. Flexible 1+1 Cavity Dual-Purpose Structure
The exclusive 1+1 cavity design enables one mold to complete both sample verification and batch production. Customers can first confirm product appearance, size and assembly performance through trial cavity, then start formal mass production, which effectively avoids mold modification risks, saves secondary mold opening costs and accelerates product launch progress.
2. Large Sprue Horn Solves Filling Defects
Charger base parts are usually equipped with mounting columns, reinforcing ribs and thick wall areas, which are easy to cause insufficient filling and shrinkage. The upgraded large sprue horn increases feeding flow and speed, ensures full cavity filling, stabilizes injection pressure, and greatly reduces defective rate of finished electronic parts.
3. 738H Steel Ensures Stable Long-Term Production
738H mold steel with HRC35-40 moderate hardness has good toughness and pressure resistance, not easy to deform or crack during long-term repeated injection. It features excellent polishing and texturing performance, perfectly supports VDI24 uniform texture processing, and maintains consistent surface effect in mass production.
4. Standard VDI24 Texture for Electronic Grade Appearance
VDI24 fine matte texture is a mainstream appearance standard for consumer electronic shells. It effectively covers minor mold marks and injection lines, provides uniform and delicate matte touch, makes the charger base look more high-end, and meets strict appearance requirements of electronic products.
5. Professional ABS Material Mold Optimization
Aiming at ABS material’s shrinkage and fluidity characteristics, we optimize cooling channel layout and venting system. The finished charger base features high size accuracy, good assembly compatibility, no obvious warpage or burrs, fully adapting to mass assembly production of electronic products.

FAQ
Q1: What is the advantage of 1+1 cavity mold compared with ordinary single cavity mold?
A1: 1+1 cavity has both trial production and mass production functions. It can verify product design in advance, avoid overall mold modification, greatly save time and cost for new product development.
Q2: Why adopt large sprue horn for charger base mold?
A2: Charger bases have irregular structures and thick ribs. The large sprue horn provides faster and more stable material feeding, ensuring full filling and reducing shrinkage and short shot defects.
Q3: Is VDI24 texture suitable for electronic product shells?
A3: Yes. VDI24 fine matte is the most commonly used surface standard for consumer electronics, with uniform texture, good anti-slip performance and high-grade appearance.
Q4: Can we customize different textures or polish surfaces?
A4: Absolutely. We can provide VDI, SPI and other custom surface finishes according to customer requirements.
