This product series focuses on the defense and combat equipment sector, dedicated to producing engineering plastic core components that can withstand harsh environments, possess high strength and impact resistance, and achieve lightweight design. These components can be used not only as independent components but also integrated with metal parts, such as metal stampings, primarily for vehicle platforms, individual soldier equipment, and weapon station interfaces. Our unique advantage lies in our ability to control the entire process of plastic components, from mold design and material selection to injection molding, ensuring they possess characteristics such as vibration resistance, impact resistance, a temperature range of -40℃ to 85℃, and chemical corrosion resistance, thereby guaranteeing the combat readiness of equipment.
Jinyi Mould, leveraging its manufacturing system in the precision engineering field, extends its quality management experience from the automotive sector to the military industry. We are proficient in the assembly and integration of plastic parts and metal structural components such as military Humvee parts, and are committed to providing solutions from rapid prototyping to large-scale, efficient delivery.
The materials we use include glass fiber reinforced nylon (PA6+GF30), polyetheretherketone (PEEK), and PC-ABS alloy. For example, PA6+GF30 material has high rigidity but is 50% lighter than aluminum alloys of equivalent strength. To manufacture parts compatible with the "Condor" tactical equipment components, we employed an optimized surface treatment process that comprehensively considered material properties, actual operating environments, and other factors. This improved wear resistance ensures that parts maintain a good surface condition under various friction and scratching forces, reducing wear and damage. It also enhanced weather resistance, guaranteeing stable performance and quality under harsh environments such as high temperature, high humidity, extreme cold, and strong ultraviolet radiation, preventing premature aging and corrosion due to environmental changes.
The molds are made of H13 hot work die steel and S136 stainless steel. Key components undergo special surface treatments to enhance wear resistance. Through Moldflow simulation, we predicted and optimized the filling path and cooling rate, controlling the molding shrinkage of large, complex plastic parts within ±0.15%. Simultaneously, military components made from metal stampings ensure precise assembly.
We provide rapid prototyping services to our clients to test new designs. For example, designing prototypes for new ballistic helmet accessories (such as night vision goggle mounts). We can efficiently handle modifications or special orders for surplus military parts kits to meet urgent spare parts needs.
Ballistic helmet accessories made of materials such as ultra-high molecular weight polyethylene (UHMWPE) offer excellent shrapnel and ballistic protection while being lighter than traditional materials.
These housings are primarily used to enclose and protect electronic equipment. Engineering plastics such as PC/ABS and reinforced PBT can be used through injection molding to achieve excellent dustproof, waterproof, and shockproof capabilities.
In relevant applications, using glass fiber reinforced plastics (GFRP) or composite materials to replace traditional materials can effectively reduce the overall weight of the equipment and the maintenance costs associated with material wear and tear and damage.
Rifle stocks, handguards, magazines, pistol grips, and scope mounts for military equipment. Made with materials such as glass fiber reinforced nylon, which is lighter than metal, non-conductive, and corrosion-resistant, significantly improving soldier mobility and sustained combat capability.
Furthermore, we conduct more stringent quality verification than in the commercial sector to ensure these parts meet military requirements.
All batches of components undergo high and low temperature cycling testing (-40°C to 85°C), triaxial vibration testing (compliant with MIL-STD-810G), salt spray corrosion testing (ASTM B117), and UV aging testing. Components used in ballistic helmet accessories also undergo special testing.
We use coordinate measuring machines (CMMs) for 100% inspection or high-frequency sampling inspection of critical assembly interfaces. We also regularly test materials for their mechanical properties, including tensile strength, flexural modulus, and impact strength, and maintain these test records to ensure traceability.
We implement a traceability process from raw material granules to final product batches. All materials are certified to meet RoHS, REACH, and military standards.
The company can support full lifecycle manufacturing needs, from small-batch R&D and pilot production to medium-batch equipment upgrades and large-scale installations. Whether developing lightweight plastic components to replace existing military Humvees or manufacturing system components for next-generation Condor tactical equipment, we provide design and manufacturing support.
