This product line focuses on providing the Military Manufacturing sector with high-reliability custom engineered plastic parts that meet specifications such as MIL-STD-810. These components are key infrastructure components that constitute modern military product systems (such as field communication terminals, reconnaissance equipment casings, and vehicle control modules). The core requirements are to maintain dimensional stability, electromagnetic shielding (EMI) effectiveness, and long-term reliable connections with metal components under extreme environmental stress.
As a precision engineering link in the supply chain, JinYi Mold not only provides injection molding, but also focuses on material selection for environmental adaptability, lightweight and reinforced design based on finite element analysis (FEA), and digital production process control to ensure batch consistency. Our engineering capabilities also support the development of highly integrated lightweight modules and protective housings for a wider range of tactical survival equipment and tactical recovery equipment.

Mainly used are glass fiber reinforced nylon (PA66+GF30, tensile strength >180 MPa), polyetheretherketone (PEEK 450G, continuous use temperature 250°C) and polycarbonate/ABS alloy (PC/ABS, notched impact strength ≥50 kJ/m²). Material selection was based on data on its resistance to wide temperatures (-54°C to 85°C), salt spray, hydraulic fluids and JP-8 fuel.
For radome-like components that require both high strength and signal transmittance, glass fiber-reinforced PPS or PPA materials with specific dielectric constants will be used.
The mold is made of S136 (mirror polished), H13 (hardness HRC 48-52) or NAK80 steel. In response to the wear and tear of glass fiber materials, key core components are treated with PVD coating (such as CrN) to extend the mold life to more than 800,000 mold cycles.
Through Moldex3D mold flow analysis, the gate and cooling system design is optimized to control the molding warpage of large thin-walled parts (such as equipment casings) within 0.2%, and eliminate the negative impact of weld lines on structural strength.
An all-electric injection molding machine is used, combined with in-mold sensors to monitor cavity pressure and temperature in real time and lock the process window (CpK ≥ 1.67) to ensure batch stability.
CNC precision machining (guaranteed mounting surface flatness 0.05mm), ultrasonic welding (air tightness reaches IP67), laser marking (for permanent component traceability), and selective electromagnetic shielding (EMI) coating.

Our quality control system follows the AS9100D Aerospace Quality Management System Framework and meets Military Manufacturing requirements for traceability.
In addition to conventional dimensional testing (CMM), UV aging (ASTM G154), salt spray corrosion (ASTM B117), vibration (MIL-STD-167), drop and high and low temperature cycle tests can be performed according to customer specifications, and data reports are provided.
For housings with integrated electronic components, conduct EMI shielding effectiveness testing (up to 40dB or more) and heat dissipation simulation verification. All parts pass functional assembly inspection before shipment.
From raw material batches, mold maintenance records to process parameters of each production shift, all are entered into the MES system to support complete traceability.

JinYi Mold supports flexible modes from rapid prototyping (using 3D printing or soft molding) to small and medium batch (100-10,000 pieces) production. In response to the common rapid iteration requirements of tactical survival equipment and tactical recovery equipment projects, we can complete design changes and deliver new version prototypes within 2-3 weeks through modular mold design.
If your military product project requires a plastic component solution that combines lightweight, environmental resistance and precision integration, we can provide professional engineering and manufacturing support. Please provide performance requirements and initial drawings and we will initiate a manufacturing feasibility analysis.
