This product line focuses on providing rapid development and low-volume manufacturing solutions for mission-critical 3D printed parts for the defense, aerospace and high-end industrial fields. Military components often face challenges such as extreme environmental adaptability, high strength-to-weight ratio, complex internal structures, and emergency spare parts requirements. However, traditional manufacturing methods have long cycles and high costs. With its profound background in precision mold manufacturing, JinYi Mold innovatively combines the Design for Additive Manufacturing (DfAM) concept with a variety of SLA/SLS/FDM 3D printing services, providing one-stop services covering conceptual design, rapid prototyping and direct manufacturing of functional parts, effectively shortening the equipment development and maintenance cycle.
We are not only a manufacturing service provider, but also a partner in 3D printed product development support for our customers. Through the early participation process, we assist customers in redesigning parts, leveraging the technical advantages of 3D printing to achieve integration, lightweighting and performance improvement, and perfectly combine additive manufacturing with traditional subtractive manufacturing (CNC) or injection molding processes to provide customers with hybrid manufacturing solutions that are time and cost-effective.

Our engineers use DfAM principles to perform topology optimization of parts, remove redundant materials and achieve lightweighting while ensuring mechanical properties; design complex lattice structures or internal flow channels, which cannot be achieved by traditional processes. For shell components, we quickly verify assembly and ergonomics through plastic 3D printing.
We select the best process based on the end use of the part, Use SLA (light-curing) technology to produce models or inspection tools with high detail and smooth surfaces. Engineering plastics such as nylon are used using SLS (Selective Laser Sintering) technology to create strong and heat-resistant components. Through metal 3D printing for industrial use (such as SLM/DMLS), titanium alloy, aluminum alloy or stainless steel are used to manufacture end-use parts that can withstand high loads and high temperatures, such as brackets, heat sinks or customized tools.
Professional post-processing of 3D printed parts enables final dimensional accuracy, surface finish and mechanical properties. These processes include support removal, sand blasting, polishing, heat treatment (for metal parts) and CNC finishing. We can also precisely assemble complex core components manufactured through 3D printing with other parts produced using traditional processes to form complete finished components.

We have established a strict additive manufacturing quality control system for the military and industrial fields.
Traceability and certification of every batch of printing materials. The metal printing process parameters have been verified, and material mechanical property test reports (such as tensile and fatigue tests) can be provided according to customer requirements.
From digital model comparison, online monitoring during the printing process, to post-finished three-dimensional coordinate measurement (CMM) or industrial CT scanning, we ensure that the geometric dimensions and internal quality of each component meet strict standards.
Components can undergo vibration testing, salt spray testing, high and low temperature cycle testing and other environmental adaptability verification as required to ensure their reliability under actual working conditions.
We offer a highly flexible and responsive service model: from single-piece rapid prototyping to low-volume end-part production of tens to hundreds of pieces. Whether it's a custom mount for a gear upgrade, a lightweight housing for an unmanned device, or replacing a discontinued legacy part, we can provide a solution in a fraction of the time.
If your project is limited by the cycle time and cost of traditional manufacturing, or you are designing the next generation of products with innovative structures, JinYi Mold's advanced 3D printing comprehensive solutions will be your powerful partner.
