This mold was designed specifically to address the stringent requirements that military-grade plastic parts need in their applications. These parts have been required to remain functional for an extended period under stringent conditions that include extreme temperatures between -54°C to 125°C, high-intensity vibrations, sandstorms, as well as exposure to salt spray corrosion. By drawing experience from our knowledge base in delivering precision parts for high-security road security devices, security product safes, as well as complex security devices, we at Military Molds have optimized their precision parts molds to dizzying heights with our concept of zero defects.
JinYi Mold’s competitive advantages emanate from fully integrating military standards and the latest mold technology. Right from the molecular structure of the mold materials to mold machining, we have established an engineering preventive system. Simulations before the deployment of molds help us eliminate possible dangers in mass production, and thus when military spare parts are installed, they attain the desired reliability.

Mold life directly affects component cost and security of supply. Material: the choice for the mold will be either maraging steel or pre-hardened corrosion-resistant mold steel. Performance criteria include: a HRC 52-54 hardness, very low sulfur and phosphorus composition for improved toughness, and very high thermal conductivity for efficient cooling. For use where there may be resistance to CWAs or special corrosive environments, the mold can have a PVD coat applied.
Optimized gating and cooling systems provide balanced filling of high viscosity engineered plastics like PEEK, PEI, and PA66-GF50 with minimized molding forces.
Simulation of operating conditions of molds with long cycles and high frequency in injection molding and enhancing critical structural molds and/or slide blocks to withstand early fatigue fractures.
Core parts are processed through five-axis high-speed milling and slow wire EDM with high matching accuracy between the cavity and the slide block, as well as long-term stable operation.
The injection molding workshop is furnished with injection molding machines that are capable of closed-loop pressure and temperature measurement. These machines enable the monitoring and adjustment of the process parameters for every mold. We have implemented a traceability system that was originally established for the high-end safety product manufacturing process. Thus, digital files have been created for every mold and every batch of manufactured parts. They enable traceability from particles to finished product.
The level of validation that we carry out is significantly higher than what is expected in the civil sector. The system that we have developed meets all the strict criteria required by the military and the security sector.
Molds must undergo process window verification in order to detect the safety limits within which the production parameter must lie. This is because molds are expected to produce parts that have a defined parameter standard.

Military plastic parts manufactured have to qualify, but not be limited to, the following testing procedures.
Temperature shock, damp heat, dust, and salt spray tests as per MIL-STD-810.
Sine sweep and Random Vibration, Mechanical Shock, and Static Load.
UL94 V-0 flame retardability, UV aging resistance in critical zones, and resistance to specified chemical agents.
Our production process is compatible with AS9100D aviation standards related to quality management, while also facilitating customers in adhering to military inspection system standards like MIL-I-45208A.
JinYi Mold offers one-stop services from collaborative design, mold engineering, trial molding optimization, to mass production, as well as logistics services. In order to satisfy the demand for spare parts in the military, we have implemented a mold health management and maintenance plan to ensure that after extended periods of shelf life, molds can activate, and spare parts can be produced with their original specifications quickly. If your project needs plastic parts to work correctly in very harsh environments and an engineering firm with a strong foundation in materials science and predictive maintenance, we can help. We ask for your mission requirements, and we will start the technical coordinating process.
