Research and development cycle shortened by approximately 50%, mold investment cost reduced by about 90%
In recent years, Dongying Jiayang Precision Metal Co., Ltd. has successfully integrated SLA(Stereolithography) 3D printing technology with lost wax casting processes, significantly shortening the R&D cycle for casting complex parts by nearly 50%, and reducing mold investment costs by about 90%. This has overcome the long mold manufacturing cycle and high costs associated with traditional precision casting processes in many urgent projects and small batch orders.
3D printing technology generates three-dimensional solid models by stacking materials layer by layer, which has the following significant advantages over using molds to create wax patterns:
1. No mold manufacturing: Skips the time-consuming 2-4 weeks of mold opening, quickly generating high-precision resin prototypes of castings based on 3D data, compressing urgent order delivery cycles to 1-2 weeks, and the cost of SLA printed resin molds is only about 10% of that of metal molds;
2. Integrated forming of complex structures: Supports structures such as hollow channels and irregular surfaces that are difficult to achieve with traditional processes while retaining details;
Jiayang has established a 3D printing center in collaboration with Dongying Technician College, which is currently equipped with 5 SLA devices, capable of printing parts with a maximum profile of 800mmx800mmx550mm, with a monthly capacity exceeding 200 pieces. This can flexibly meet the needs for sample trials and small batch urgent orders.
â–²Application of 3D printing in precision casting
Case Study: Winning Recognition from Clients Worldwide with Technical Strength
Impellers, guide vanes, etc. (pump components, Europe, America): A globally renowned large pump client often has small batch and urgent order demands in the aftermarket. 3D printing combined with precision casting technology can quickly deliver such orders at a lower cost, perfectly meeting the client’s needs. Jiayang has completed nearly a thousand such orders for this client in recent years, greatly enhancing the client’s trust in the company.
nozzle rings (turbine parts, Europe): A newly designed nozzle ring raised uncertainties regarding its castability and potential casting defects at the initial design stage. The product has a large size profile (approximately 600mm), a high number of blades (29), and a small thickness (as thin as 1.5mm), and creating a mold for sample trials would require an investment of over 100,000 yuan and take at least 6 weeks. Jiayang quickly produced rough sample pieces at a very low cost using SLA 3D printing technology, confirming that casting defects could be effectively avoided. The samples received high praise from the client upon their first presentation.
Support frames (parts for the construction industry, Europe): The structural design provided by the client had small part thickness, and the inner holes and outer edges were prone to shrinkage defects. Jiayang optimized the product structure design and quickly provided samples at a lower cost using 3D printing technology, visually demonstrating potential defects in various structures and offering solutions, while also improving the product’s process yield. This earned high recognition from the client for Jiayang’s quick response and professional technical support.
Through continuous technological accumulation and practical application, Jiayang has successfully provided rapid response services to numerous international clients from Germany, France, Switzerland, the Netherlands, Italy, and New Zealand at economical costs.
Outlook: Deep Integration of 3D Printing and Traditional Precision Casting
Jiayang continues to deepen the technological development and practical application of 3D printing, ensuring stable casting quality through a comprehensive quality management system. Currently, the company is capable of rapid prototyping for complex structures in various fields such as pump parts, valve components, instruments, food machinery, marine machinery, and automotive parts, as well as meeting small batch urgent order demands.
In the future, with the deeper integration of 3D printing technology and traditional precision casting technology, the R&D of casting processes will accelerate towards intelligence and efficiency. Jiayang will take this opportunity to align with technological development trends, providing clients with faster, more flexible, and more economical services.
