We are a national high-tech enterprise dedicated to the research, development, and manufacturing of high-end precision injection molds. With years of experience in the daily necessities and home appliance sectors, we specialize in the design and manufacture of insulation box molds. Leveraging our extensive technical expertise and innovative spirit, we provide customers with one-stop, cost-effective solutions from concept to mass production.
Why choose our insulation box molds?
1. Accurate and proactive Design for Manufacturing (DFM) analysis ensures success from the start.
Before mold design begins, our team of engineers will provide you with a professional Design for Manufacturability (DFM) analysis report. Using advanced Moldflow software, we simulate the filling, packing, cooling, and shrinkage of the melt within the mold cavity. This accurately predicts and addresses potential sink marks, air pockets, weld line locations, and deformation risks. This ensures a first-time success rate for your mold solution, significantly reducing development time and costs.
2. Ingenious Mold Structure Design
Given the double-walled, hollow interior, complex structure, and high sealing requirements of insulated boxes, we offer customized structural solutions:
High-Efficiency Core Pulling System: Utilizing a combination of a long-stroke inclined lifter and high-precision slides, or sequential core pulling with a hydraulic cylinder, this system perfectly solves the mold release challenges of complex internal structures, delivering smooth and reliable operation.
Perfect Sealing Solution: The sealing grooves between the box body and lid utilize slow-cut wire cutting (accuracy ±0.005mm) and precision mirror-finished EDM, ensuring dimensional tolerances of only ±0.02mm and superior airtightness.
Uniform Cooling Design: Based on mold flow analysis, a multi-circuit, zoned cooling system is designed to prioritize cooling in the thick-walled areas of the box body, effectively minimizing product deformation, shortening molding cycles, and improving production efficiency.
3. Superior Mold Quality and Material Selection
We understand that mold life directly impacts your production costs.
Core Steel: Major inner mold components are made of imported high-quality steel, such as Swedish ASSAB 718H and S136, offering high wear and corrosion resistance and excellent polishing properties.
Surface Treatment: Based on customer requirements, the inner cavity can be mirror-polished to international standards (A0-A1), or various custom etched (leather) effects can be applied to meet diverse product appearance requirements.
Standard Parts: Key standard components such as hot runners, guide pins, and precision positioning are all sourced from internationally renowned brands, ensuring long-term stability and reliability of the mold.
4. Stable and Efficient Automated Production Support
Our mold designs fully meet the requirements of modern intelligent manufacturing.
Hot Runner System Application: High-performance hot runners are standard, effectively reducing runner waste and saving material costs while enabling fully automated injection molding.
Automation Interfaces: The mold features a built-in interface for robotic part removal, and the optimized mold opening stroke and ejection mechanism ensure seamless integration with automated equipment, enabling unmanned workshop production.
