How to Get Quality CNC Plastic Services

Plastic parts are mostly using injection molding for mass production. However, CNC plastic machining offers distinct advantages over injection molding, rapid prototyping, and 3D printing. The result of CNC plastic can be bringing out tighter tolerances, and working for a wider range of materials, also it is more economical suitable for low volumes than injection molding.

1. Know the value of plastic CNC machining

In theplastic CNC machining process, the part is machined by removing a plastic material block with digital milling machines. It is commonly used as a rapid prototyping technology which is suitable for unit or low volume production (between 1 to 10,000 parts) in the pre-production run of functional testing and verification.

CNC machining of plastic prototype part is a wide selection of resins allows parts to be obtained in the exact material, which allowing mechanical properties close to the injection molded part. Often materials as ABS, PC, PP, PVC, POM, PMMA, PA, etc can be manufactured more efficient and faster than other rapid prototyping methods for plastic prototypes of small lots demand.

At Sanwo Rapid, we are good at plastic CNC machining for parts with large sizes greater than 600mm.

2. Select the optimal CNC machining methods

In general, metal machining equipment can be used for cutting plastic parts as well. Because of the large different between the mechanical properties of plastics and metals, also with the wide variety, different plastics also have great differences in machining problems. In order to avoid issues or problems in plastic machining, choosing the optimal machine tools can be help a lot in CNC machining technologies.

Over 80% ofCNC plastic parts are CNC milled. It is the most widespread method for manufacturing plastic components without a revolution axis. The rest of is usually using a lathe, which also known as CNC turning process.

3. Choose the right plastic materials

Materials choosing is usually required under two reasons: mechanical performance and cost.

ABS, PVC, and PP are the most commonly-use due to its plasticity and favorable price.

Acrylic (PMMA) has outstanding strong, stiff, clear plastic available in a variety of brilliant colors and finishes, and its cost is medium suitable.

HDPE is a durable, versatile, abrasion and chemically resistant plastic material.

Nylon, a strong, stiff engineering plastic often used to replace metal bearings, and bushings.

PC (Polycarbonate) can be transparent or opaque. It is strong and stiff thermoplastic with outstanding impact resistance.

PEEK performs over a wide range of temperatures with outstanding chemical resistance.

Below the plastic material options that Sanwo Rapid can manufacture:
