Key Structural & Molding Advantages
1. 1×2 Balanced Cavity High Production Structure
The symmetrical 1×2 cavity layout ensures completely consistent melt flow speed, filling pressure and cooling effect for two control panel parts at the same time. It effectively avoids size deviation, warpage and unbalanced shrinkage easily occurred in large flat PC panels. Double output greatly improves production efficiency and reduces the unit mold cost for mass production.
2. Large Gate Design Specially Optimized for PC Material
PC material features high viscosity and high melting point, which is easy to produce silver streaks, air lines and incomplete filling with small gates. This mold adopts a large gate feeding structure to reduce shear force during injection, make melt flow smoothly, exhaust air rapidly, and completely eliminate common PC defects. It ensures full filling of thin and large panel surfaces with uniform and stable transparency.
3. S136 Heat-Treated Steel for High Transparent Parts
Cavity and core adopt S136 stainless steel after strict heat treatment, with stable internal structure, high hardness, excellent corrosion resistance and super high polishing performance. It can achieve ultra-smooth mirror surface, ensuring the finished PC panel has high light transmittance, no mold point, no pitting and no water ripple. Heat treatment greatly improves mold toughness, effectively avoiding mold deformation and abrasion during long-term high-pressure PC injection.
4. High Flatness & High-Precision Panel Molding
Switch control panels and horn panels require extremely high flatness, assembly tolerance and surface clarity. The mold is equipped with optimized circulating cooling system and precise positioning structure, which effectively controls PC shrinkage and prevents panel bending and warpage. All assembly holes, buckles and mounting positions maintain high consistency to ensure perfect assembly matching.
5. Stable Quality for Long-Term Mass Production
With S136 anti-rust steel and scientific cooling runner layout, the mold is not easy to rust, stain or scale during long-term production. It keeps the transparent PC parts always bright and clean, greatly reducing mold maintenance frequency and improving production stability. It is the most reliable customized mold solution for electronic transparent panel mass production.
Application Scope
This PC injection mold is widely used for producing transparent panels for household appliances, smart electronic devices, audio speakers, switches, industrial control equipment and other fields, including horn decorative panels, touch switch panels, transparent display covers and functional transparent plastic parts.
Conclusion
The 1×2 cavity PC large gate injection mold adopts heat-treated S136 high-quality steel and PC professional large-flow gate design. It perfectly solves various difficult molding problems of transparent PC panels, realizing high transparency, high flatness and high-precision mass production of switch and horn panels. It is a high-stability and long-life professional electronic plastic mold.
