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.

Wholesale Medical Grade Titanium Bone Screw Orthopedic Implants Manufacturer Custom OEM Surgical Screws Factory Direct

Product Overview

Manufactured from Titanium Alloy (Ti-6Al-4V), it is used in orthopedic surgery. The part requires extreme precision, biocompatibility, and a burr-free finish. Sunmy Hardware utilizes advanced Swiss-type CNC lathes to produce such micro-components.

Manufacturing Process Insight

Swiss Turning

The guide bushing technology supports the workpiece close to the cutting tool, minimizing vibration. This allows us to turn long, slender parts with zero deflection.

Thread Whirling

We use a specialized thread whirling attachment to cut the deep, sharp bone threads in a single pass. This results in superior surface quality and faster cycle times compared to single-point threading.

Deburring & Cleaning

Parts undergo ultrasonic cleaning and microscopic inspection to ensure no foreign particles remain.

Key Features & Benefits

Biocompatibility

Titanium Grade 5 is lightweight, non-magnetic, and biologically inert, making it safe for long-term implantation.

Micro-Precision

Tolerances are held to ±0.005mm to ensure secure engagement with surgical tools.

Surface Integrity

A smooth surface finish prevents tissue irritation and bacterial growth.

Traceability

Full material lot traceability is maintained for every batch, crucial for medical compliance.

Technical FAQ

Q1: Is it difficult to machine Titanium?

A1: Titanium is tough and generates heat during machining. We utilize specialized high-shear tooling, optimized feed rates, and high-pressure coolant systems to machine titanium components efficiently and accurately.

Q2: What is the smallest diameter you can turn?

A2: Our Swiss-type CNC lathes can reliably handle micro-diameters as small as 1mm while maintaining high precision and stability.

Q3: Can you provide material certificates?

A3: Yes, all medical-grade parts come with complete material certifications (EN 10204 3.1 certs), heat treatment records, and full dimensional inspection reports.

Q4: What standard tolerances can your Swiss CNC machines achieve?

A4: We consistently maintain micro-tolerances down to ±0.005mm (5 microns) depending on part geometry, critical dimensions, and material requirements.

Q5: Do you offer post-processing and surface finishing in-house?

A5: Yes, we provide comprehensive surface finishing services including ultrasonic cleaning, passivation, titanium anodizing, and microscopic deburring tailor-made for medical applications.

Q6: What is your typical lead time for custom prototype and production runs?

A6: Fast-track prototype samples can be completed in 3 to 7 business days, while standard full-scale production runs take approximately 2 to 3 weeks depending on batch volume.
