Military-grade nylon injection molding is not a common type of plastic processing. It involves the use of high-quality nylon, which requires military standards, with injection molding technology used to make polymer parts for military tools with enhanced strength and reliability.
The intervention of this product series is aimed at making effective use of engineering plastics like PA6-GF/PA66-GF through high-pressure injected molding to produce important components for military equipment that possess a high structural strength, light weight, and specific functions like electromagnetic shielding. These produced components should provide geometric stability with a working efficiency that functions well in temperatures ranging from -40°C to 120°C, under constant vibrations, and in field chemical environments, thereby directly influencing the reliability of individual military equipment. We possess a strong ability to provide complete integrated injected molding services for military communication equipment with integrated radio frequency shielding.
JinYi Mould oversees the injection molding process of military projects under the IATF 16949 quality system, and our company adheres to the standards of precision manufacturing of power train automotive components to our military equipment. We specialize in the hybrid integration of plastic and metal components that meet military standards, focusing on key manufacturing process mastery, such as insert molding and ultrasonic welding, to achieve permanent bonding between the materials.
We use reinforced nylon with a 20%-50% weight ratio of glass fibers, which provides a tensile strength of 80-160 MPa. To satisfy the electromagnetic interference shield performance standard as defined for a military-grade RFI shield, we add a stainless steel fiber or a nickel-plated carbon fiber to support a 30-60 dB electromagnetic interference attenuation value at a 30 MHz to 1 GHz frequency band, as defined by MIL-STD-461 specification standards.
In fact, the molds are made from pre-hardened S136 or H13 hot-working mold steel, and the mold design has been improved in consideration for typical problems during the process of military equipment parts molding, namely wrinkles and thin walls. In addition, mold flow analysis with Moldex3D optimizes gating and cooling designs, ensuring that the dimensional difference within the nylon parts due to moisture absorption or the cooling process does not exceed ±0.08%.
To produce military-standard plastic and metal components, we carefully pre-place metal inserts in connectors into the mold cavity before injection molding and overmold them with melted nylon for structural consolidation to prevent assembly mistakes. The injection molding machine uses a closed-loop servo system to control injection pressure variation within±1% to ensure mechanical consistency for injection-molded products.
Stocks and grips don’t form critical parts of the firearm and can thus incorporate lightweight designs.
The essential items like military helmets and combat armor. Even as these are essential for protection and strength, they are designed to be as light as possible.
The products including walkie-talkie cases, battery cases, and GPS device protective cases have very good impact resistance, sealing, and electromagnetic shielding properties.
Additionally, we make use of a specifically defined verification procedure for the military-grade components made from nylon.
Volume resistivity analysis and Shielding Effectiveness (SE) verification testing are done on each lot of the shielding nylon. Tensile, bending, and Izod Notched Impact Strength tests are also done on various military plastic parts.
Finished products are also subjected to high and low temperature cycles from -40°C to 85°C, high humidity cycles, a 48-hour salt spray test, a 500-hour UV aging test, and chemical corrosion immersion tests involving materials such as diesel fuel and insect repellents.
A thorough examination of functional assembly characteristics is carried out with a 3D coordinate measuring machine (CMM). RF leakage scan testing is done for shield housings. In the case of military-standard hardware components, dynamic load testing is completed post-installation to simulate operating conditions.
The delivery capabilities at JinYi Molds are able to meet a wide variety of requirements, whether for pilot-scale production with rapid prototyping for smaller quantities to bulk deliveries of tens of thousands for production line delivery and installation projects. In upgrading current military-standard plastic products to design and develop advanced generational RF shielded self-contained radio enclosures for the military, JinYi Molds is able to offer extensive assistance.
