What is your minimum order quantity for custom parts?

We support single-piece prototypes and low-volume runs through CNC machining, 3D printing and urethane casting, and scale to mass production through die casting, injection molding and stamping. Share your target quantity and our engineers will recommend the most cost-effective process.

What tolerances can Sunmy Hardware hold?

Standard CNC tolerances are ±0.01 mm, and critical features can be held down to ±0.005 mm. Dimensions are verified with CMM inspection and documented in FAI reports before shipment.

How do you protect my drawings and intellectual property?

We sign a Non-Disclosure Agreement with you by email before collecting any 3D or CAD files. You work directly with the factory, so your data is never handed off to brokers.

Which quality documents are available with shipments?

Material certificates, RoHS compliance documents, First Article Inspection (FAI) reports and CMM dimensional reports can be supplied per project.

Which manufacturing processes are done in-house?

CNC machining and stamping are performed in our own facilities. Casting and surface finishing are completed by audited partners. All final quality control, CMM inspection and FAI are executed in-house by Sunmy engineers before global shipping.

Which CAD file formats do you accept?

We accept STEP, IGES, STL, DWG/DXF and PDF 2D drawings. Physical samples can also be reverse-engineered.

Custom Stainless Steel Waterproof Sensor Probe Housing Thermowell OEM ODM Manufacturer Wholesale

Product Overview

Shenzhen Sunmy Hardware Co., Ltd. presents our high-performance Stainless Steel Sensor Probe Housing, specifically engineered for temperature sensing, soil moisture detection, and fluid monitoring systems.

Designed with a robust, pointed tip structure, these housings are ideal for applications requiring direct insertion into soil, viscous liquids, or pressurized water pipes. As a specialized manufacturer of Precision Turned Parts, Sunmy offers full OEM/ODM support, allowing us to customize the length, diameter, wall thickness, and flange design to perfectly match your sensor modules (DS18B20, PT100, etc.).

We provide a durable shield for your sensitive electronics against moisture, corrosion, and physical impact.

Manufacturing Process & Insights

Our probe housings are manufactured using advanced CNC Precision Turning (Computer Numerical Control) technology. Unlike standard stamping or tube drawing, our turning process ensures superior structural integrity and dimensional accuracy.

Precision CNC Turning

The pointed tip is machined directly from solid bar or thick-walled tube stock, ensuring a seamless, leak-proof transition that is stronger than welded tips.

Surface Treatment

We apply a high-grade polishing process to reduce surface roughness. This minimizes soil adhesion or fluid drag and ensures easy cleaning and sterilization (vital for food/beverage or medical applications).

Sealing Interface

The open end features a precision-machined flange or rolled rim designed to accommodate O-rings or epoxy potting, ensuring high waterproof reliability (customizable to IP68 standards).

Key Features & Advantages

Superior Thermal Conductivity

The precision-machined thin-wall design ensures rapid thermal response, transferring temperature changes from the medium to the internal sensor quickly.

Excellent Corrosion Resistance

High-quality Stainless Steel 304/316 construction provides longevity in harsh environments, including saltwater, acidic soil, and industrial chemical tanks.

High Penetration Capability

The tapered, pointed tip design allows for easy installation into compact soil or semi-solid materials without bending the tube.

OEM Customization Power

Custom logo laser engraving
Specific thread types (NPT, BSP, Metric) machined at mounting end
Adjustable wall thickness for high-pressure environments

Technical FAQ

Q1 What is the Minimum Order Quantity (MOQ) for a custom probe size?

At Sunmy, we support our clients' development phases. For custom dimensions, we can start with a low MOQ for prototyping (e.g., 50-100 units) before moving to mass production.

Q2 Can you ensure the housing is waterproof?

The metal housing itself is seamless at the tip due to the CNC turning process, making it 100% leak-proof. The final waterproof rating depends on how you seal the open end (epoxy potting or end-cap). We can design the flange specifically to hold your preferred sealing method securely.

Q3 Do you provide material certification?

Yes. We are a transparent manufacturer. We provide material certificates (RoHS, REACH, Mill Certs) for our Stainless Steel 304/316 materials upon request to ensure compliance with your local regulations.

Q4 I need a specific shape for the tip (e.g., needle-sharp vs. rounded). Can you do it?

Absolutely. Since we use CNC Lathes, we can program any tip geometry you require—whether it’s a sharp needle for piercing or a rounded bullet tip for safety.

Q5 What is the typical lead time for custom samples and bulk production?

Custom sample prototypes generally take 5–7 working days depending on structural complexity. Bulk production orders typically take 12–18 days after sample approval.

Q6 How do you guarantee precision tolerances across large batches?

We utilize high-precision CNC automatic lathes equipped with optical measuring instruments. Every batch undergoes 100% critical dimension checks and thread gauging before shipment.
