Custom Manufacturing Solutions

Delivering precise realization solutions for complex structures and specialized specifications.

We have established a highly resilient manufacturing network designed specifically to tackle the challenges of complex geometric structures and specialized materials.

Unlike standard OEM models that merely execute based on drawings, we introduce Design for Manufacturability (DFM) assessments in the early stages of a project. This allows us to help you identify potential risks and eliminate process bottlenecks before production begins.

To address the common needs for "multi-process integration" and "high-precision tolerance control" in custom projects, we integrate Turn-Mill (Mill-Turn), Electrical Discharge Machining (EDM), Grinding, and various Surface Treatment resources. From single-piece Prototype Verification to Pilot Runs, we are committed to bridging supply chain gaps and providing stable, industrial-standard deliverables. We are your most reliable long-term partner for product development and specialty component manufacturing.


Our Service Scope

One-stop cross-process manufacturing support to successfully realize your designs:

✔️ Complex Structural Components
Supporting precision manufacturing needs for multi-axis machining, thin-wall structures, and freeform surfaces.
✔️ Hard-to-Cut Material Machining
Specializing in engineering plastics (PEEK, Torlon®) and special alloys (Titanium, Inconel), with process parameter optimization to ensure dimensional stability.
✔️ Global High-Mix Support
Providing a highly flexible "High-Mix Low-Volume" manufacturing mode specifically for international clients, supporting export logistics and quality standard alignment.
✔️ Prototype to Pilot Run Integration
Offering seamless process transition from high-fidelity Mockups to small-batch Pilot Runs.
✔️ Surface Treatment Management
Integrating Anodizing, Passivation, Electropolishing, and Plating services to ensure consistent final quality.
Core Advantages (Why SY Tech?)

1. Material Mastery

We possess deep expertise in the deformation characteristics of high-end engineering plastics and the machining challenges of corrosion-resistant metals. Through stress relief processes, specialized clamping design, and strategic machining sequencing, we effectively control deformation risks to ensure parts fall within design tolerances.

2. Flexible Capacity

Facing the fluctuating demands of custom projects, we can dynamically adjust production schedules and resource allocation. This represents not just equipment flexibility, but total supply chain integration, helping clients mitigate uncertainties caused by urgent orders or design changes.

3. Engineering-Grade Evaluation

Before production, every project undergoes a comprehensive DFM assessment. If high structural risks or unnecessary cost inefficiencies are identified, we proactively propose optimization suggestions to ensure the part achieves the best balance between "functional requirements" and "manufacturing efficiency."

4. Cross-Process One-Stop Integration

High-end products often cannot be completed by a single process. We integrate CNC Precision Machining, EDM, Grinding, and Surface Treatment for you. You only need to interface with a single point of contact to ensure smooth process transitions and clear accountability.

5. Rigorous Quality Inspection Standards

Even for low-volume custom parts, we maintain industrial-grade QA processes. Using high-precision metrology equipment, we ensure that Critical Feature Sizes and Geometric Dimensioning and Tolerancing (GD&T) meet drawing specifications, providing full inspection reports upon request.

Solving Common Manufacturing Challenges

We not only provide capacity but also assist you in overcoming production difficulties from an engineering perspective:

Common Field ChallengeOur Solution
Complex structure; impossible with a single processIntegrating Turn-Mill and EDM technologies to break down processes and precisely achieve complex geometric features.
Plastic parts deform easily after machiningImplementing material stress relief processes and optimizing tool paths and clamping methods to ensure dimensional stability.
Fragmented supply chain; unclear accountabilityProviding one-stop turnkey services, managing material sourcing, machining, finishing, and assembly under a single point of contact.
Low pilot run volume; low supplier supportEstablishing a high-flexibility production mode for global clients, fully supporting verification needs during the R&D phase.
Difficulty combining heterogeneous materialsProviding "Metal × Plastic" composite design and assembly advice to resolve issues related to differences in thermal expansion coefficients.
Applications & Target Sectors
🔹 Precision Mechanical Components
Automation transmission mechanisms, high-precision slide rail accessories, complex linkages, and special joints.
🔹 Special Environment Applications
Critical components for vacuum, high-temperature, strong acid/alkali, or high-wear environments (e.g., heat-resistant insulators, corrosion-resistant valve bodies).
🔹 R&D Functional Verification (R&D Prototype)
Creating high-fidelity prototypes using Real Materials prior to mass production for structural testing and functional verification.
📘 Case Studies: Manufacturing Optimization & Quality Improvement
Case 1 | Deformation Control of Complex Thin-Walled Parts
🔴 Challenge: PEEK thin-walled parts warped after machining, affecting assembly precision.
🔵 Solution: Adjusted machining allowances and introduced stress relief processes between roughing and finishing.
✅ Result: Flatness stably controlled within tolerance; established a standard manufacturing process.
Case 2 | Multi-Process Integration Development
🔴 Challenge: Parts required CNC, heat treatment, grinding, and plating. Subcontracting caused lead time delays and unclear responsibility.
🔵 Solution: We acted as the single point of contact, establishing In-Process Quality Control (IPQC) standards for each stage.
✅ Result: Total lead time reduced by 30%, with zero quality disputes.
Case 3 | Metal-to-Plastic Lightweighting
🔴 Challenge: Stainless steel inspection jigs were too heavy, difficult to handle, and scratched the products being tested.
🔵 Solution: Proposed switching to high-strength engineering plastic (Torlon®).
✅ Result: Weight reduced by 70%, maintaining rigidity while effectively protecting the product surface.
