This product line focuses on using industrial-grade polymer additive manufacturing (3D printing) technology to directly produce end-use plastic parts for national defense, aerospace and high-end industrial fields. These parts replace traditional metal or injection molded parts and need to meet the extreme environmental requirements of standards such as MIL-STD-810. The core challenge is to simultaneously achieve military-standard flame retardancy (UL94 V-0), electromagnetic interference (EMI) shielding up to 60dB, resistance to fuel/hydraulic oil corrosion, and a weight reduction target of more than 50%.
JinYi Mold combines material research and development with digital production to provide small batch production from rapid functional verification prototypes to direct service parts. We draw on the strict biocompatible material control process in the additive manufacturing of medical equipment and the design experience of dynamic load structures in the additive manufacturing of automotive parts to ensure the functional integrity and long-life reliability of defense-grade hardware under harsh conditions.
We mainly use high-performance polymers such as carbon fiber reinforced polyetherketoneketone (CF-PEKK) and polyetherimide (PEI). After testing, CF-PEKK parts can continue to work in an environment of 180°C, have a tensile strength of more than 120 MPa, and meet the UL94 V-0 flame retardant rating. Working with materials laboratories, we can customize material formulations based on the mission profile to achieve specific dielectric constants, radar wave transmission or radiation resistance.
Generative design software (such as nTopology, Altair Inspire) is used to automatically generate a weight-optimal structure under given load and boundary conditions. In this case, a 62% weight reduction was achieved for a communication equipment shell. Use laser powder bed fusion (SLS) or fused deposition modeling (FDM) processes to create functional prototypes for product design verification and early testing of assembly, thermal management and electromagnetic compatibility (EMC).
Not only do we manufacture end parts, we also produce additive manufacturing molds for low-volume injection molding. Conformal cooling channels can be integrated inside these molds, shortening the injection molding cycle by approximately 25%. For the final parts, we perform post-processing through precision CNC machining, sandblasting and special coatings (such as conductive paint, scratch-resistant coatings) to ensure that they meet the surface finish below Ra 1.6 μm and strict dimensional tolerances required by the drawings.
We have established a dedicated quality control process for additive manufacturing that is in line with the spirit of the AS9100 aerospace quality management system.
From design files, printing parameters to each batch of materials, all are encrypted and traced through the blockchain-based document management system to ensure that the data throughout the entire life cycle of the component cannot be tampered with.
All parts used directly require dimensional verification through coordinate measurement (CMM) or industrial CT scanning. We perform Environmental Stress Screening (ESS) based on customer specifications, including but not limited to: temperature cycling from -40°C to 85°C, 6-axis random vibration testing at 15G, 48-hour salt spray exposure, and targeted chemical reagent immersion testing.
We can provide customers with material mechanical property test reports (including tensile, bending, fatigue data) issued by NADCAP certified laboratories, and support customers' first article inspection (FAI) process.
JinYi Mold specializes in small-batch additive manufacturing production of 50 to 500 pieces, which perfectly matches the needs of special equipment R&D and trial production, battlefield emergency spare parts support, and continuous support of legacy equipment (Legacy System). Through our digital inventory system, discontinued plastic parts can be quickly resumed based on original drawings, eliminating the risk of supply chain interruptions.
