Optical materials & transparent components：

We machine high-quality optical components using transparent materials such as PMMA (acrylic) and polycarbonate (PC). These materials are widely used for transparent parts in automotive lighting, home appliances, compressors, displays, and other applications where clarity and appearance matter.

Our custom optical components are designed to meet both functional and aesthetic requirements. Transparent parts are often used to enable optical performance, allow visibility of internal structures, or enhance the overall appearance of a product.

To achieve excellent clarity and light transmission, we apply advanced finishing processes. PMMA components are polished through precision mechanical and manual polishing, while PC components achieve high transparency through controlled vapor polishing.

We support 3-axis, 4-axis, and 5-axis CNC machining, enabling flexible production of optical parts from prototypes to medium-volume orders (1 to 10,000 pieces) with consistent quality.

* Material selection support is available to optimize performance, cost, and machinability.

Strict Quality Inspection Standards

SzCrealink applies rigorous quality inspection standards throughout the CNC machining process to ensure high precision while maintaining cost efficiency. Every project is managed under controlled processes, with strict attention to material properties, machining methods, and tolerance requirements.

We follow recognized tolerance standards to ensure consistency and reliability: metal components are produced according to DIN 2768-1 Fine, while plastic components comply with DIN 2768-1. Based on material type and processing requirements, all critical dimensions are carefully monitored during production to achieve the required machining accuracy.

Our quality assurance system is supported by a full range of inspection equipment. Manual measuring tools include calipers, micrometers, height gauges, plug and ring gauges, thread gauges, and surface roughness testers. For high-precision inspection, we use advanced measuring instruments such as CMM (Coordinate Measuring Machines), optical projectors, image measuring systems, roundness gauges, and cylindricity gauges. This combination ensures comprehensive inspection and reliable verification of every part before delivery.

CNC Machining Tolerance Standards

1.For metal parts, use the DIN-2768-1-FINE standard.
2.For plastic parts, use the DIN-2768-1 standard.

Comprehensive CNC Machining Services for Precision Manufacturing

We provide a full range of CNC services, including metal and plastic machining, advanced surface treatments, and complete manufacturing solutions. From prototyping to mass production, our precision CNC capabilities ensure high accuracy, durability, and fast delivery for industries worldwide.

From Raw Material to Shipment - How Our CNC Machining Factory Gets It Done

At our CNC machining factory, every project follows a clear, step-by-step process to ensure quality and consistency from start to finish.
It all starts with your quote request. Once the order is confirmed, we source raw materials and run them through strict Incoming Quality Control (IQC) before storage. Then, machining begins – with a First Article Inspection (FAI) to confirm everything is on track.
Next comes mass production, supported by ongoing In-Process Quality Checks (IPQC). For complex parts, we repeat the inspection and machining cycle to ensure accuracy at every stage. Once finished, the parts are stored, carefully packed, and shipped to your door.
Every step is controlled, documented, and handled with care – so you get reliable results, every time.

Material Matters. And We Prove It.

Q: What happens if the material quality isn’t guaranteed in CNC machining? How do you handle this?

A: Poor material quality can lead to serious problems – parts may fail, dimensions can be off, or the final product might not meet performance standards. It can also damage trust if there’s no proof of what material was used.

Here’s how we make sure that doesn’t happen:

– Trusted suppliers only – We buy materials from certified, reliable sources.

– Material certificates – We provide official material reports or third-party test results with your order.

– Incoming inspection – Our team checks materials before they’re used to ensure they meet the required specs.

– Full traceability – Every batch of material is tracked so we always know where it came from.

– Clear communication – We let you know exactly what material we’re using before production starts.

This way, you can be confident that the parts you receive are made from the right materials – every time.

Worried About Part Quality?

Q: What if the parts I receive don’t meet the quality I expected?

A:That’s a common concern – and it’s a big one. If parts aren’t made to the right specs, it can cause delays, extra costs, or even product failures.

Here’s how we make sure your parts meet your standards:

– Clear checks at every step – We inspect your parts before, during, and after production.

– Detailed quality reports – You get full inspection reports with key measurements.

– Precision tools – We use professional equipment like CMMs to check accuracy.

– Consistent quality – Our team follows strict processes to keep every batch the same.

– Reliable support – If something’s not right, we’ll fix it – fast.

We stand behind our work, so you don’t have to worry about surprises.

Clear. Fair. Explained. How We Handle CNC Pricing

Q: CNC machining prices are often unclear. How do you make it more transparent?

A: We get that a lot – many customers come to us after getting vague or inconsistent quotes elsewhere. That’s exactly why we’ve built a clear and transparent quoting process.

When you send us your drawings (ideally in STEP format), we don’t just throw out a number. We provide a detailed breakdown: material cost, machining time, setup, surface finish, and any custom features. If anything isn’t clear, we’re happy to explain how each part of the price is calculated.

We also use digital tools to estimate machining time more accurately, based on your actual part geometry. For repeat orders or similar parts, we keep pricing consistent and fair – and we always update quotes if there are design changes.

In short, we want you to feel confident about what you’re paying for – and to know there are no hidden costs.

Trust Through Security: How We Handle Your CNC Files

Q: Is data and protection a concern in CNC machining? How do you handle it?

A: Yes – and we take it very seriously. When customers send us 3D files or technical drawings, they’re sharing more than just shapes – they’re sharing valuable designs, sometimes even patented ideas. We understand how important that trust is.

That’s why we keep all files secure and private. We never share your data with anyone else, and access is strictly limited to the engineers who need it to make your parts. If you prefer, we’re always ready to sign an NDA before reviewing any files.

Your design stays your design – we just help you bring it to life, safely and professionally.
