This product line is designed to provide high-reliability, weather-resistant plastic component solutions for military equipment in extreme field environments, covering tactical communication equipment casings, electronic warfare component casings, and individual soldier equipment structural parts. These components need to be able to withstand the environmental tests of wide temperatures, high humidity, salt spray, vibration shock and electromagnetic interference. As a manufacturer deeply engaged in the field of high-end medical device injection mold manufacturing and precision test kit plastic molds, JinYi Mold has transformed the medical industry's ultimate pursuit of sterility, biocompatibility and precision sealing into engineering standards for absolute reliability, absolute sealing and long-term stability of military products, achieving cross-domain quality sublimation.
We know that whether it is medical equipment to protect lives or military equipment to ensure mission success, the inherent quality requirements for core plastic components are the same - zero defects, full traceability, and ultra-long life. With an engineering team of more than 500 people and the systematic process of ISO 13485 medical device quality management system, we provide one-stop manufacturing services for military projects from scientific selection of materials, anti-environmental stress design to strict verification.

Drawing on our experience in dealing with complex chemical reagents in kit plastic injection molds, we select engineering plastics (such as high-performance PC, PPS, PEI) with extremely high levels of chemical resistance, UV aging resistance, and flame retardancy for military parts. At the same time, the knowledge of biocompatible materials accumulated in plastic injection molding of medical parts is used to ensure that the selected materials are safe and stable when exposed to skin for a long time or in special environments.
The mold uses highly corrosion-resistant and high-toughness mold steel, and focuses on optimizing filling balance and cooling uniformity through Moldflow mold flow analysis to offset the internal stress of components under extreme temperature cycles and prevent cracking or deformation. As a professional medical device injection mold manufacturer, the ultra-high surface finish processing and micron-level tolerance control we are good at are also used to ensure the electromagnetic sealing (EMI/RFI) performance and waterproof level of military enclosures.
We provide value-added services beyond basic molding, including metal insert molding, conductive coatings, vibration-resistant structural design, and permanent laser traceability markings that meet military regulations. Our clean shop environment ensures cleanliness during the packaging of highly sensitive electronic components.
We will implement a more rigorous validation process than commercial standards that combines medical rigor with military-grade reliability.
Conduct DFMEA (Design Failure Mode Analysis) from the beginning of the project and ensure the robustness of the production window through process validation (IQ/OQ/PQ). The entire process follows the management and control standards of ISO 9001 and ISO 13485.
In addition to dimensional accuracy (CMM) and mechanical performance testing of product components, we can assist customers in arranging or providing high and low temperature cycle, damp heat, salt spray, vibration and impact testing that comply with MIL-STD-810 and other standards to simulate real battlefield environments.
We have established a full-chain traceability system from raw materials to finished products, which can provide complete material certification reports, first article inspection reports (FAI), process parameter records and test reports for each batch of products, and can support the qualification review and acceptance required by customers.
We understand the strict requirements for confidentiality, supply chain security and delivery nodes of military industry projects. With the rapid response and flexible batch adaptation capabilities we have developed as a kit manufacturer, we can efficiently support needs at all stages, from emergency prototyping to mid- to long-term stable supply.
