In the fiercely competitive environment of precision manufacturing, Shengpeng Hardware has stood out by leveraging its expertise in stainless steel CNC Machining, and has become a trusted partner.
With 18 years experience, we specialize in transforming high-quality stainless steel into precise and durable components, serving industries such as automotive, medical, aerospace, and household appliances.
Our commitment to precision, efficiency, and customer satisfaction has made us the preferred choice for enterprises seeking reliable CNC processing solutions for stainless steel.
Whether you need small-batch prototypes or large-scale production, we will customize services according to your unique requirements.
At Shengpeng Hardware, we integrate advanced technology with meticulous craftsmanship to offer outstanding Stainless Steel CNC Machining. Here are our key advantages:
The precision of our CNC machines can reach ±0.005 mm, ensuring that every stainless steel component meets the strict design standards.
This high level of precision is crucial for industries such as healthcare and aerospace, as even small deviations can affect performance.
We have purchased the most advanced machines: CNC lathes, milling machines and engraving machines - including five-axis machines - which can handle complex stainless steel geometries with ease.
Our equipment is calibrated regularly to maintain optimal performance and enhance production efficiency.
No two projects are exactly the same. We work closely with our clients to understand their design goals and provide tailor-made stainless steel CNC processing solutions.
From adjusting part sizes to optimizing surface treatments, we can meet your specific needs.
Our process is structured to ensure consistency and quality at every stage. The table below outlines key steps, equipment, and specifications:
| Step | Equipment Used | Tolerance Range | Typical Stainless Steel Grade |
|---|---|---|---|
| Design & Programming | CAD/CAM Software (AutoCAD, Mastercam) | N/A | 304, 316, 430 |
| Material Preparation | Precision Saws | ±0.1mm | 304, 316, 430 |
| CNC Machining | 3-axis/5-axis CNC Mills/Lathes | ±0.005mm to ±0.02mm | 304, 316, 430 |
| Surface Finishing | Polishing, Passivation, Sandblasting | N/A | 304, 316, 430 |
| Quality Inspection | CMM (Coordinate Measuring Machine) | ±0.001mm | 304, 316, 430 |
Every step is monitored by our quality team to ensure there are no defects – from the inspection of raw materials to the testing of final components.
Stainless steel is a top choice for CNC machining, and for good reason. Its unique properties align with the demands of high-performance industries:
Corrosion Resistance: Unlike carbon steel, stainless steel contains chromium (≥10.5%), forming a protective oxide layer that resists rust—ideal for outdoor or wet environments (e.g., marine parts).
High Strength: It maintains structural integrity under high temperatures and pressure, making it suitable for automotive and aerospace applications.
Hygiene: Stainless steel is non-porous and easy to clean, meeting strict hygiene standards for medical devices and food-processing equipment.
At Shengpeng, we primarily work with grades 304 (versatile, cost-effective), 316 (high corrosion resistance), and 430 (magnetic, ideal for household appliances).
Our components power critical operations across multiple industries. Here are some common use cases:
Medical Industry: Surgical instruments, implantable parts, and diagnostic equipment components (machined to FDA standards).
Automotive Industry: Exhaust system parts, fuel injectors, and brake components (resistant to heat and vibration).
Household Appliances: Oven doors, sink drains, and refrigerator hinges (durable and easy to maintain).
Aerospace Industry: Engine brackets and hydraulic system parts (meet AS9100 quality standards).
The product quality of Shengpeng Hardware Company is extremely strict. Our quality control process involves verifying each stainless steel CNC-machined component. The following table lists our key quality control measures:
| Check Item | Testing Method | Acceptance Standard | Frequency |
|---|---|---|---|
| Dimensional Accuracy | CMM & Calipers | Meets client’s design tolerances | 100% of parts |
| Surface Smoothness | Profilometer | Ra ≤ 0.8μm (per client request) | Random sampling (20% of batch) |
| Corrosion Resistance | Salt Spray Test | No rust after 48–96 hours | Per batch |
| Material Authenticity | Spectrometer | Matches specified stainless steel grade | Per raw material lot |
We also hold ISO 9001 and IATF 16949 certifications, ensuring our processes align with global quality standards.
Our MOQ is very flexible - we accept small batch orders (the minimum can be 1 piece for prototype production), and also large-scale production orders (10,000 pieces or more).
The delivery time depends on the complexity and quantity of the product. Prototyping takes 3 to 7 days, while mass production requires 2 to 4 weeks. For urgent orders, we offer expedited services.
Yes! We regularly machine grades like 304, 316, 430, 321, 410. If you need a specific grade, we can source it from trusted suppliers.
Absolutely. We provide polishing, passivation, sandblasting, electroplating, and powder coating to enhance durability and aesthetics.
We will sign NDAs with all our clients. Your design files and project details are stored in a secure system with password protection.
We are ISO 9001 (general manufacturing) and IATF 16949 (automotive) certified. For medical projects, we comply with FDA regulations.
Yes. We collaborate with reliable logistics providers, which enables us to deliver goods to over 50 countries, including the United States, the European Union, Japan and Australia. We handle the relevant customs declaration documents to simplify the delivery process.
We offer a 100% rework or refund guarantee. If a part doesn’t meet standards, we immediately reprocess it at no extra cost.
Whether you are developing new products or expanding production scale, Shengpeng Hardware can provide you with the precision, reliability and flexibility required for stainless steel CNC processing.
Our engineers and technicians will work with you from the design stage until delivery, ensuring that your project can be completed on time and exceed expectations.
