Introduction: Not More Services — The Right Ones
When customers ask, “What manufacturing services do you offer?”, they’re not looking for a long list.
They’re trying to answer a more practical question:
•Can you actually make my part?
•Can you handle it from prototype to production?
•Can I avoid dealing with multiple suppliers?
Many suppliers list everything — CNC, molding, casting, printing — but in reality, only a few processes truly matter for most mechanical parts.
At SzCrealink, the focus is simple:
Do a few manufacturing processes well, and make them work together.
This article breaks down the four core services we provide, and more importantly, how they apply to real-world projects.

Overview of Our Core Manufacturing Services
We focus on four essential capabilities:
•CNC Machining
•Sheet Metal Fabrication
•Surface Finishing
•Assembly
These are not isolated services.
They are designed to work together as a complete manufacturing solution.
CNC Machining: The Core of Precision Manufacturing
What CNC Machining Actually Solves
CNC machining is the most reliable way to produce:
•High-precision parts
•Complex geometries
•Functional mechanical components
It is the backbone of most industrial products.
Our CNC Machining Capabilities
•3-axis, 4-axis, and 5-axis machining
•CNC milling and turning
•Tight tolerance control (±0.01–0.05 mm)
•Prototype to batch production
Supported Materials
Metals
•Aluminum (6061, 7075)
•Stainless steel (303, 304, 316)
•Carbon steel
•Copper and brass
Plastics
•ABS
•POM (Delrin)
•PTFE
•Acrylic (PMMA)
•Nylon
When to Use CNC Machining
CNC is the right choice when:
•You need tight tolerances
•The part has complex geometry
•Material strength matters
•Quantity ranges from 1 to a few thousand
Real Example
Part: Aluminum heat sink housing
Requirements:
•Complex internal channels
•Tight tolerance for assembly
•Good surface finish
Solution:
•5-axis CNC machining
•Secondary finishing
Result:
•Stable fit
•Reduced assembly issues
Sheet Metal Fabrication: Efficient for Structural Parts
What Sheet Metal Is Best For
Sheet metal fabrication is ideal for:
•Enclosures
•Brackets
•Cabinets
•Structural frames
Our Sheet Metal Capabilities
•Laser cutting
•CNC bending
•Welding
•Riveting
Materials
•Stainless steel
•Carbon steel
•Aluminum sheets
When to Choose Sheet Metal Instead of CNC
| Scenario | Better Choice |
| Flat or folded structures | Sheet metal |
| Thick solid parts | CNC machining |
| Large enclosures | Sheet metal |
Key Advantage
Sheet metal significantly reduces cost for large, thin-walled structures.
Real Example
Part: Electrical enclosure
Requirements:
•Lightweight
•Corrosion resistance
•Medium batch production
Solution:
•Laser cutting + bending
•Powder coating
Result:
•Lower cost than CNC
•Faster production
Surface Finishing: Not Just Appearance
Surface finishing is often treated as optional.
In reality, it directly affects:
•Corrosion resistance
•Wear resistance
•Product appearance
•Assembly performance
Our Finishing Capabilities
| Process | Function |
| Anodizing | Corrosion resistance (aluminum) |
| Powder coating | Durable protective layer |
| Sandblasting | Matte texture |
| Polishing | Smooth or transparent surface |
| Plating | Conductivity / protection |
When Finishing Becomes Critical
•Outdoor applications
•High-humidity environments
•Visible consumer products
•Precision fitting surfaces
Common Mistake
Many designs ignore finishing until the end.
Result:
•Dimension changes
•Poor appearance
•Rework
👉 Finishing should be considered at the design stage
Assembly Services: Turning Parts into Products
What Assembly Includes
•Mechanical assembly
•Fastener installation
•Sub-assembly integration
•Functional testing
Why Assembly Matters
Without assembly support:
•You manage multiple suppliers
•Risk of mismatched parts increases
•Lead time becomes unpredictable
With Assembly Integration
You get:
•Better consistency
•Shorter lead time
•Fewer errors
Real Example
Project: Industrial device housing
Scope:
•CNC machined parts
•Sheet metal enclosure
•Surface finishing
•Final assembly
Result:
•Single supplier coordination
•Faster delivery
•Reduced overall cost
How These Services Work Together
Most real projects are not single-process.
Typical Workflow
1.CNC machining for precision parts
2.Sheet metal for structural components
3.Surface finishing for protection and appearance
4.Assembly for final product
Key Advantage
Integration reduces risk more than it reduces cost.
How to Choose the Right Manufacturing Approach
1. Based on Geometry
•Complex solid → CNC
•Flat or folded → Sheet metal
2. Based on Quantity
| Volume | Recommended Approach |
| 1–10 | CNC machining |
| 10–500 | CNC + sheet metal |
| 500+ | Optimized hybrid solution |
3. Based on Cost
•Avoid machining large flat parts → use sheet metal
•Avoid tight tolerances where unnecessary
4. Based on Function
•Load-bearing → CNC
•Enclosure → Sheet metal
Common Mistakes Buyers Make
1. Choosing the Wrong Process
Using CNC for sheet metal parts = unnecessary cost
2. Over-Specifying Tolerances
Not every dimension needs ±0.01 mm
3. Ignoring Finishing Impact
Surface treatment changes dimensions
4. Splitting Suppliers
More suppliers = more problems
FAQ
What is your core manufacturing service?
CNC machining is the primary capability, supported by sheet metal, finishing, and assembly.
Can you handle both metal and plastic parts?
Yes, including aluminum, steel, copper, and engineering plastics.
Do you support small quantity orders?
Yes, from prototype to batch production.
Can you provide finished products?
Yes, including surface finishing and assembly.
How fast can you deliver?
•CNC machining: 3–7 days
•Sheet metal: 5–10 days
•Assembly: depending on complexity
Final Thoughts: Focus Beats Variety
Offering more services doesn’t make a supplier better.
What matters is:
•Depth of capability
•Process control
•Integration
At SzCrealink, the focus is not to offer everything, but to deliver reliable manufacturing where it actually matters.
If you have a project in mind, the fastest way forward is simple:
Send drawings → review process → optimize early
Because in manufacturing,
the biggest cost is usually not production — it’s correction.
