2 Why CNC machining POM (Acetal) Materials？

Injection molding and extrusion molding are common POM plastic molding processes,

then in what case do you need to use cnc machining technology for POM molding?

CNC (Computer Numerical Control) machining technology is often used for POM in the following conditions:

**Complex Geometries**

When the part design includes intricate shapes, tight tolerances, 

and complex geometries that are challenging to achieve with traditional molding processes.

**Prototyping and Small Batches**

For producing prototypes or low-volume production runs, 

CNC machining is more cost-effective and faster compared to creating molds for injection molding.

**High Precision and Tight Tolerances**

CNC machining can achieve very high precision and maintain tight tolerances,

 which is essential for applications where exact dimensions are critical.

**Custom or Specialized Parts**

When manufacturing custom or specialized parts that cannot be mass-produced economically via injection molding.

**Material Properties**

When retaining the material properties of POM is crucial, as CNC machining does not involve the high temperatures 

of injection molding that can alter the material's characteristics.

**Rapid Turnaround**

When a quick turnaround is needed for part production, CNC machining provides a faster solution 

compared to the lead times associated with mold creation and setup.

**Surface Finish Requirements**

When the parts require a specific surface finish or post-processing that is more easily achieved with CNC machining.

In these scenarios, CNC machining of POM provides the advantages of precision, flexibility, and quality, making it a preferred choice 

for many engineers and manufacturers.CNC machined POM parts is the perfect combination of high precision and durability.

4  Lori’s Quality Control and Inspection

Quality control and inspection are crucial in ensuring the quality of CNC machined POM parts. 

We adhere to strict quality control standards through the following measures:

**Raw Material Testing** 

Before processing, we rigorously test POM raw materials to ensure they meet quality standards 

and customer requirements. This includes assessing key indicators such as hardness, density, and wear resistance 

to confirm the reliability of the raw material.

**Machining Process Monitoring** 

During CNC machining, we continuously monitor the machine tool's operating status and processing effects in real-time. 

Using professional monitoring equipment and software, we can promptly detect and address any abnormalities 

to ensure the precision and surface quality of the parts.

**Finished Product Inspection** 

After machining, we conduct a comprehensive inspection of the finished product. 

This includes checking key indicators such as dimensions, shape, and surface roughness to ensure the parts meet design and customer specifications. 

Additionally, we perform functional tests on the parts to verify they meet performance requirements in actual use.
