Lingyufab (Shanghai Lingyu Industrial Co., Ltd.), established in 2003, is a premier manufacturer of tooling fixtures with over 20 years of precision sheet metal fabrication experience. We produce custom welding fixtures, machining fixtures, assembly fixtures, and inspection fixtures from carbon steel, stainless steel, and aluminum. As a Mitsubishi Electric certified core supplier adhering to Japanese quality standards, we serve clients across automotive, industrial machinery, electronics, and aerospace sectors. From 1-piece prototypes to high-volume production, we deliver reliable, cost-effective tooling solutions.
As a China-based manufacturer located in Shanghai, Lingyufab leverages the region's robust supply chain and skilled workforce to produce high-quality tooling fixtures at competitive prices. We adhere to ISO 9001:2015 quality management system. Our in-house production eliminates outsourcing costs, delivering 15 to 20 percent cost savings to customers. We support 1-piece samples, 100-piece pilot runs, and high-volume mass production with monthly output exceeding 5,000 units.
Our tooling fixtures are engineered to precise specifications.
Lingyufab specializes in producing custom tooling fixture parts including:
Each part is tailored to your workpiece geometry, production process, and accuracy requirements. Our engineering team provides upfront technical support, including design optimization, tolerance analysis, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.
What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, stamping, welding, and surface treatment, into a seamless manufacturing workflow for tooling fixtures. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. With our in-house fastener manufacturing, we can pre-install locating pins, clamps, and assembly hardware directly onto your fixtures, eliminating external sourcing and reducing setup time on your end. The result is a streamlined, cost-effective solution that provides reliable positioning, repeatable accuracy, and long-term performance in demanding production environments.
Tooling fixtures offer precise positioning and secure clamping with several key features. They are constructed from carbon steel, stainless steel, or aluminum for high structural rigidity and dimensional stability. Standard features include accurate locating pins and datum surfaces for repeatable positioning, quick-release clamps for fast loading and unloading, and hardened wear surfaces for long service life. Modular designs allow for easy reconfiguration, and custom designs can be tailored to specific workpiece geometries. Surface finishing options include powder coating, galvanizing, and anodizing. Full material traceability with Mill Test Certificates (MTC) for every batch.


Our tooling fixtures are widely deployed in welding production lines for precise positioning and clamping of metal structures, CNC machining centers for secure workpiece holding during milling and turning, sheet metal assembly for accurate component alignment and fastening, and quality inspection for repeatable measurement and first-article verification. They are also used in automotive manufacturing for body-in-white assembly and powertrain machining. They ensure production accuracy, repeatability, and efficiency in demanding manufacturing environments. Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.
A tooling fixture is a metal structure used to securely position and clamp workpieces during production processes such as machining, welding, assembly, and inspection. It ensures repeatable accuracy, reduces setup time, and maintains consistent quality across production runs. Fixtures are typically made from carbon steel, stainless steel, or aluminum, with locating pins, datum surfaces, and clamping mechanisms designed for specific workpiece geometries. They are essential in automotive, industrial machinery, electronics, and aerospace manufacturing.
Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.
When designing and fabricating tooling fixtures, consider the following guidelines:
Thickness typically ranges from 3.0mm to 20.0mm depending on load and rigidity requirements.
Precision is critical for tooling fixtures to ensure proper workpiece positioning, repeatable production, and consistent quality. Lingyufab maintains the following accuracy standards:
These standards are maintained through advanced laser cutting, CNC bending, and welding equipment, combined with rigorous in-process inspection and final quality control checks.
Lingyufab implements a comprehensive quality control system for tooling fixtures:
Tooling fixtures can be fabricated into various configurations to suit different applications:
