This product line provides engineering development and manufacturing services for plastic and metal integrated components for military equipment. The core is to solve system-level challenges such as structural connection, thermal expansion matching, electromagnetic compatibility (EMI) and lightweight integration between heterogeneous materials (such as engineering plastics and aluminum alloy/stainless steel). Such components are commonly found in modular communication terminals, individual soldier system carrying frames, quick disassembly interfaces and equipment-level impact-resistant structures. Through the "Design for Manufacturing and Assembly (DFMA)" process, we integrate injection molding, die casting, CNC machining and joining processes up front, aiming to deliver highly integrated subsystems that can be directly assembled, rather than just discrete parts.
Our engineering practices incorporate experience in serving clients with high international standards. In the process of participating in projects that comply with the harsh environmental regulations of Israeli defense forces equipment and providing key structural components for the American security products market, the full-process traceable quality control system and rapid prototyping response capabilities established by JinYi Mold form a solid foundation for serving global Military-grade equipment projects.
Mainly made of glass fiber reinforced high-temperature nylon (such as PA66-GF35, heat distortion temperature HDT @1.8MPa >250°C), polyetherimide (PEI/Ultem) and polyetheretherketone (PEEK) to meet the requirements of structural strength, weather resistance and low outgassing.
Use 6061-T6 or 7075-T6 aluminum alloy (CNC machining), magnesium alloy (die-casting) or 17-4PH stainless steel for critical connection points that require high specific strength, fatigue resistance or electromagnetic shielding.
Use topology optimization technology to embed metal inserts in the plastic body, or design various connection interfaces such as buckles, ultrasonic welding, and structural bonding to ensure the reliability of heterogeneous material interfaces under vibration and impact loads.
Plastic molds are made of S136, H13 (hardness HRC 48-52) steel, and have special flow channels and ejection designs for insert molding (Insert Molding) or in-mold assembly. The metal die-casting mold is made of high-quality H13 steel and nitrided to extend its life.
Equipped with a five-axis linkage CNC machining center, it can perform finishing processing on plastic-metal composite parts under one-time clamping, ensuring that the position accuracy across the material reference plane is ≤0.05mm. Provides military-standard surface treatments such as micro-arc oxidation (applicable to magnesium-aluminum alloys), electroless nickel plating, Dacromet coating, etc.
The production line integrates in-mold sensing and visual inspection systems to monitor the cavity pressure curve of plastic injection molding and the tool wear status of metal CNC machining in real time to achieve predictive maintenance.
Plastic pellet batches, metal billet sources, process parameters and quality data are bound and traced through the Manufacturing Execution System (MES).
Our verification system is based on standards such as MIL-STD-810 (environmental engineering considerations) and MIL-STD-461 (electromagnetic compatibility), and is tailored and deepened according to specific project requirements.
Focus on vibration (three-axis random vibration), mechanical shock (half sine wave, peak acceleration up to 50G), high and low temperature cycles (-54°C to 85°C) and salt spray corrosion combined tests to assess the long-term integrity of the connection interface of heterogeneous materials.
For components containing circuits or signals, conduct EMI shielding effectiveness (≥30dB attenuation) testing and waterproof and dustproof (IP67 level) verification. All connection interfaces must pass a plug-in, pull-out or disassembly life test of ≥500 times.
In the Designing Military Grade Product stage, finite element analysis (FEA) is used to conduct multi-physics (structural, thermal, electromagnetic) coupling simulation to reduce physical iteration risks with virtual testing.
JinYi Mold supports the entire process from "rapid functional prototyping (using 3D printing and rapid CNC)" to "small and medium-sized batch flexible production". Drawing on our experience in developing products for brands that have extreme requirements for durability, such as tuffy security products, we can quickly adapt and meet the specific design needs of various military-grade equipment in terms of field maintainability and modular upgrades.
If your equipment project involves a complex plastic-metal integrated structure and requires a solution that combines lightweight, high reliability and rapid deployment capabilities, we can provide professional support from conceptual design, engineering simulation to manufacturing integration. Please provide initial requirements and performance specifications and we will initiate a technical feasibility analysis.
