CNC Machining Plastic Parts Service

CNC machining plastic is a subtractive manufacturing process that uses computer numerically controlled machines to cut material, the process of removing plastic or metal from a block (“blank”) using high-speed, precision machines to create parts.

With hundreds of professional production equipment and rich experience, SEAL-RP can provide customers with prototype CNC manufacturing services for various mechanical plastic to ensure part quality and precision, and fast production speed.

As prototyping CNC machining does not require the creation of molds, manufacturers can start production faster than other processes. Prototype CNC machining is highly automated and can be produced with minimal labor input during and outside of working hours.

What‘s more, multiple CNC machines can work from the same design, simultaneously producing identical parts, ultimately shortening the production cycle time, getting the product to market faster than others to take advantage of the market.

The CNC milling process is flexible and cost-effective, and offers the following key benefits

1. Excellent mechanical properties
2. Established technology
3. Wide variety of materials
4. Scalability
5. Consistency and precision
