Explore our core manufacturing outputs, featuring high-precision custom non-standard castings and precision CNC machined metal alloys designed for extreme environments.
Titanium and its prominent alloys, notably Grade 5 (Ti-6Al-4V), have emerged as the structural foundation for next-generation industrial advancements. In the aerospace sector, the drive towards fuel efficiency and structural optimization requires materials with an exceptional strength-to-weight ratio and fatigue resistance. Similarly, medical device engineers rely on titanium's unmatched biocompatibility and osseointegration properties for long-term orthopedic implants and cardiovascular housings. However, machining these components demands specialized manufacturing intelligence due to the material's unique physical traits.
At Dongguan SX Technology Co., Ltd (Shixin), we address these metallurgy challenges with advanced tooling geometry, optimized speeds and feeds, and rigid multi-axis setups. Titanium's low thermal conductivity prevents heat dissipation through the chip, localizing high thermal energy directly at the tool cutting edge. Our optimized CNC processes mitigate tool degradation through high-pressure, targeted coolant delivery and advanced physical vapor deposition (PVD) coated tooling, ensuring dimensional accuracy up to ±0.005 mm.
Unlike stainless steels or aluminum, titanium exhibits low elastic modulus, meaning it deflects easily under tool pressure. Deflection results in dimensional errors, tool chatter, and compromised surface finishes. Overcoming this requires rigid workholding systems and advanced CNC programming toolpaths, such as trochoidal milling, which reduce tool-engagement angles and control thermal buildup.
Our commitment to manufacturing efficiency, precision, and global delivery is backed by rigorous quantitative engineering metrics.
Bridging engineering excellence and supply chain efficiency to deliver world-class metal component solutions.

How our machined and cast parts perform in high-demand environments globally.
Weight reduction is critical in modern flight. Our Grade 5 titanium brackets and electronics enclosures provide essential strength while saving weight, surviving extreme temperature shifts, and resisting fatigue over long service cycles.
Titanium alloys (specifically ELI grade) feature high biocompatibility. Our climate-controlled workshop manufactures orthopedic bone plates, surgical instruments, and prosthetic connectors with ultra-low surface roughness (Ra < 0.4) to eliminate cellular friction and improve longevity.
Marine components must withstand chloride pitting. Our custom stainless steel casting brackets and titanium pressure bodies operate reliably in deep-sea conditions, resisting saltwater corrosion and reducing maintenance costs for oil, gas, and renewable energy sectors.
International OEMs face supply chain volatility, raw material shortages, and shipping delays. Sourcing parts from Shixin in Dongguan offers distinct efficiency and reliability advantages. Dongguan is home to a complete industrial manufacturing ecosystem, containing raw material refineries, heat-treatment providers, standard metrology labs, and logistics centers all in close proximity.
This geographic consolidation minimizes lead times. Rather than transporting semi-finished components between isolated suppliers, our machining facility conducts roughing, precision finishing, custom heat treatment, and post-surface passivation within a localized radius. This ecosystem integration reduces material transport delays, optimizes lead times, and allows us to offer cost-competitive manufacturing solutions.
Our infrastructure supports rapid scaling, moving seamlessly from DFM design verification to CNC prototyping, pilot production, and monthly volume runs of up to 100,000 components.
Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better.
Since 2014, Shixin has continuously upgraded its quality management systems. We maintain a climate-controlled inspection lab featuring advanced measuring equipment to verify dimensional compliance before shipping.
Every production batch goes through structural inspection stages:

Get technical answers to common questions about titanium machining, casting tolerances, and project lead times.
Grade 5 titanium features high tensile strength, excellent corrosion resistance, and low density, making it ideal for high-stress applications. We machine it using slow cutting speeds, high feed rates, rigid fixtures, and continuous high-pressure coolant to prevent work hardening and localized heat damage to the tool.
For high-precision features, we consistently maintain linear tolerances down to ±0.005mm (0.0002 inches) and geometric tolerances down to ±0.01mm. We verify these dimensions in our climate-controlled metrology lab using calibrated CMMs and digital micrometers.
Yes. We offer various surface finishes, including bead blasting, electropolishing, passivation, chemical etching, and physical vapor deposition (PVD) coatings. These treatments enhance wear resistance, corrosion protection, and cosmetic appearance.
Investment casting is cost-effective for complex geometries and larger production runs, reducing raw material waste. CNC machining is ideal for tighter tolerances, simpler designs, or prototypes. We often combine both processes, using investment casting for near-net shapes and CNC machining for precision interfaces.
We provide full material test reports (MTRs) showing chemical composition and physical properties, dimensional inspection reports (CMM data sheets), and certificates of conformance. We align our quality control processes with international standards to ensure reliability for critical industrial components.
