CNC Machining Service

CNC machining is a subtractive manufacturing process include CNC milling, CNC turning, drilling presses, and CNC routing to produce highly precise parts. This process removes material from a workpiece to form the final shape and is essential in plastic fabrication.

CNC machining offers several advantages for plastic part production. It is a fast, cost-effective method for producing tight-tolerance parts without the tooling fees as injection molding.

With over 20 years of experience in precision CNC machining of engineering plastics, particularly polycarbonate sheet and acrylic sheets, Excelite Plastics provides a comprehensive manufacturing facility. We utilize the latest CNC equipment, combined with manual and automated machinery, to support both prototyping and production runs.

FAQ

Most frequent questions and answers

1. Do you have a minimum order quantity?

Excelite offers CNC machining services without minimum quantity requirements, catering to prototypes and short to medium-run production needs. Our precision machining capabilities enable us to deliver high-quality products with flexibility and efficiency, ensuring that your specific requirements are met, whether for prototyping or production purposes.

2. What's the type of design files accepted for quoting?

For the 3D drawing, we would prefer STEP, IGES, or X_T format. For the 2D drawing, we would prefer PDF format there are tolerances with the dimensions if possible.

3. How can I pay to Excelite?

You can pay Excelite through various convenient methods, including but not limited to:

1. Bank Transfer: You can opt to make payments to Excelite via bank transfer.
2. Paypal

4. What general tolerances can Excelite achieve?

General Machining Tolerances on plastics and composites will be +/- 0.010”(+/- 0.254 mm).

5. How quickly can I get my parts?

Lead times are 2 to 3 weeks for prototypes and 4 weeks for production runs. Some special urgent orders can be discussed beforehand.

6. What is the high impact resistant plastic for CNC machining?

polycarbonate is the strongest plastic for CNC. But it is easy to machine with a CNC.

7. What is the cheapest plastic for CNC machining?

Polyethylene (PE) is the cheapest plastic for CNC machining. Known for its affordability and excellent machining properties, PE is used widely in a variety of applications, including wear strips, gears, and consumer goods.
