Stamped parts Manufacturers

Stamped Parts Manufacturer & Supplier

Yuyao Hongli Optoelectronics Co., Ltd. is a China-based stamped parts manufacturer and supplier with over 20 years of manufacturing experience. From our 5,000-square-meter factory in Yuyao, Zhejiang, we produce precision stamped/stamping metal parts for automotive, electronics, home appliances, communication equipment, medical devices, and industrial machinery. Our range covers circular and square parts with holes, ultra-thin parts, metal-stamping/stamping small parts, chassis parts, base plates, and more—all customizable to your drawings or samples.

We combine high-efficiency stamping press parts processes—punching, bending, stretching, forming—with strict quality control to deliver consistent dimensional accuracy and surface finish. Whether you need prototypes, small batches, or mass production, our OEM/ODM capabilities ensure the part fits your assembly and performance requirements.

Our Stamped Parts Range

We offer a broad portfolio of stamped steel parts and other metal components, each designed for specific functional and structural roles. Below is a quick reference to our main product types and their typical applications.

Materials & Surface Finishes

We work with a wide range of metals to match your performance and cost targets. Common materials include cold-rolled steel, stainless steel, aluminum, copper, and brass. Material selection depends on required strength, corrosion resistance, conductivity, and formability.

• Steel: High strength, cost-effective, suitable for structural parts.
• Stainless steel: Excellent corrosion resistance, ideal for medical and food-contact applications—a common choice for our precision/stainless-steel stamped parts line.
• Aluminum: Lightweight, good thermal/electrical conductivity, used in electronics and automotive.
• Copper/Brass: Superior conductivity, often used for connectors and terminals.

Surface treatments are available to enhance appearance and durability: polishing, wire drawing, electroplating (zinc, nickel, chrome), powder coating, anodizing, and passivation. We recommend the finish based on your operating environment—for example, outdoor parts may require powder coating for UV and corrosion resistance, while internal components might only need a simple oil coating.

Engineering & Customization

We are not just a stamping factory; we are your engineering partner. Our team reviews your drawings or samples to optimize the part for manufacturability, suggesting material grades, thickness, and tolerance adjustments that reduce cost without compromising function. We support OEM/ODM projects from concept to production.

For each project, we consider:

• Part geometry and complexity—whether progressive die or transfer die is more efficient.
• Required tolerances—we typically hold ±0.1 mm for stamped features, with tighter tolerances possible for critical dimensions.
• Production volume—tooling design is tailored for low-volume (soft tooling) or high-volume (hard tooling) runs.
• Secondary operations—tapping, countersinking, welding, or assembly can be integrated.

Quality Assurance & Testing

Quality is embedded in every step, from incoming material inspection to final packaging. Our quality control system includes:

• First article inspection (FAI) to verify dimensions and material before mass production.
• In-process checks for dimensional stability and surface defects.
• Final inspection based on AQL standards, including visual, dimensional, and functional tests.
• Material certifications and test reports available upon request.

We also conduct salt spray tests for corrosion resistance, hardness tests, and tensile tests when required by your specification. Our goal is to deliver parts that meet your drawing exactly, every time.

Production Capacity & Lead Times

Our 5,000-square-meter facility houses multiple stamping workshops with a range of presses, from small high-speed presses for miniature parts to larger presses for chassis and base plates. We maintain a monthly production capacity of over 50,000 units, but this scales with part size and complexity.

Typical lead times are 15–30 days for standard orders, depending on quantity and tooling requirements. For new tooling, add 2–4 weeks for design and fabrication. We work with you to schedule production around your project milestones.

Packaging & Global Delivery

We ensure your parts arrive in perfect condition. Packaging is designed to prevent damage during transit—using protective wrapping, corrugated boxes, or custom foam inserts for delicate parts. We have extensive experience in international shipping, handling export documentation, customs clearance, and Incoterms to deliver to your site, whether by sea, air, or courier.

Information We Use to Configure Your Solution

To prepare an accurate quotation and production plan, please provide the following details:

• 2D/3D drawings or samples (PDF, STEP, IGES, or physical sample).
• Material specification (grade, thickness, surface finish).
• Required tolerances and critical dimensions.
• Estimated annual quantity and order frequency.
• Any special requirements (certifications, packaging, labeling).

With this information, our engineers will propose the most efficient stamping process, tooling design, and cost structure. We aim to respond with a detailed quotation within 48 hours.

Frequently Asked Questions

What is the minimum order quantity for stamped parts?

MOQ depends on part size and complexity. For standard parts, we can accommodate small batches starting from 500 pieces. For custom tooling, we typically recommend a minimum of 5,000 pieces to amortize tooling costs, but we are flexible for prototyping.

Can you work from a sample instead of a drawing?

Yes, we can reverse-engineer a part from a physical sample. We will measure and create a drawing for your approval before tooling, ensuring the final product matches your sample.

What tolerances can you hold?

Standard stamping tolerances are ±0.1 mm. For critical features, we can achieve ±0.05 mm depending on material and thickness. We discuss tolerance requirements during the quoting phase to ensure manufacturability.

Do you provide material certifications?

Yes, we can provide mill certificates for raw materials and, upon request, a certificate of conformance for the finished parts. Additional testing reports (e.g., RoHS, REACH) can be arranged.

Can you handle assembly or secondary operations?

We offer secondary services such as tapping, countersinking, welding, and simple assembly. If your part requires these, we can integrate them into the production flow to reduce your supply chain complexity.
