China Custom SS316 Deep Drawn Closed-End Flanged Sensor Housing for Temperature Probes (4mm OD) Manufacturers, Factories
Product Description
Product Overview
We specialize in the precision manufacturing of custom Stainless Steel 316 (SS316) deep drawn temperature sensor housings. This particular product features a seamless, closed-end tubular design with an integrated flange at the open end. Designed to house delicate temperature probes, such as thermistors or RTDs, this housing provides an impenetrable barrier against environmental factors like moisture, pressure, and corrosive substances. We produce these sensor shells with an outer diameter of 4mm, but can adjust all dimensions to meet your specific application requirements. Sunmy Hardware is dedicated to providing tailored solutions for your most critical sensor protection needs.
Process & Manufacturing Insights
This temperature sensor housing is produced using advanced sheet metal deep drawing and stamping technology. Deep drawing allows us to transform a flat SS316 blank into a complex, seamless tubular form with a perfectly closed and rounded end in a single production line. Our multi-stage deep drawing process ensures uniform wall thickness and a smooth interior surface, crucial for efficient sensor insertion and thermal transfer. The flange is simultaneously integrated during the stamping process, ensuring structural integrity and precise positioning for mounting. We utilize state-of-the-art precision presses and custom tooling, developed in-house, to achieve tight tolerances and exceptional surface quality. This method eliminates the need for welding, resulting in a cleaner, stronger, and more reliable product.

Main Features & Advantages
- Uncompromising Corrosion Resistance: Manufactured from genuine Stainless Steel 316, providing superior resistance to corrosion from salt water, chemicals, and elevated temperatures compared to SS304. Ideal for marine, food-grade, medical, and industrial applications.
- Seamless Integrity: Produced via deep drawing as a single, seamless piece. No welds means no potential points of failure, ensuring complete waterproof integrity and higher pressure ratings.
- Advanced Protection: Engineered to be waterproof, shockproof, and dustproof, safeguarding the internal sensor elements in harsh environments.
- Precision Engineering: We utilize multi-stage inspection processes (CMM, gauges, visual check) to guarantee dimensional precision, especially the critical outer diameter (4mm) and flange dimensions.
- Full OEM/ODM Customization: We pride ourselves on our extensive development and production capabilities. We can fully customize this sensor housing based on your technical drawings (CAD/PDF) – including changing dimensions (length, diameter), adjusting flange type (flat, threaded, grooved), specifying wall thickness, or using alternative materials (SS304, Titanium, Nickel Alloys). Our team will work closely with you from concept to mass production.
Technical FAQ
Q: Can you produce sensor housings with other diameters?
A: Yes, we can develop custom tooling for various outer diameters, ranging from small probes (e.g., 2mm) to larger industrial sensor shells.
Q: What surface finishes are available?
A: Our standard finish is a clean, polished surface from the deep drawing process. We also offer electro-polishing for enhanced corrosion resistance and a superior aesthetic.
Q: Do you offer materials besides SS316?
A: While SS316 is popular for its corrosion resistance, we can also deep draw parts from SS304, Titanium, and other specialized alloys depending on your needs.
Q: What is the typical lead time for custom mold development?
A: Depending on complexity, initial mold design and development typically take 3-4 weeks. Sample production follows. We strive for efficiency throughout the process.
Q: Can we request material certifications?
A: Yes, we provide full Material Test Certificates (MTCs) upon request for all batches to ensure material traceability and quality.
