CNC Prototyping 

A plastic prototype part ensures the product design is sound when starting a new plastic injection-molding project. For most plastic parts, a CNC machined prototype can provide exactly what is needed for testing purposes. CNC machining allows designers to test the form, fit, and function of parts that will be injection molded without the cost to produce the injection mold tooling. 

Small Production Run

Plastic injection molding is the ideal process for making hundreds, thousands, or even millions of the same part but it is not cost effective for small runs. CNC plastic machining services are the perfect manufacturing process for making a small quantity of parts. All that is needed is the CAD file and a block of plastic. CNC machining can save customers a substantial amount of money during the prototyping phase or when making only a handful of parts. CNC plastic machining services do not require the time and money needed to produce an expensive mold. Parts can be created directly on the plastic CNC machine. It is the perfect manufacturing process for runs under 100 pieces. Part runs over 200 pieces may be produced cheaper with injection molding.

Quick Turnaround Time

Plastic CNC machining services are fast and efficient. The part can be cut almost immediately after receiving the CAD file. Other manufacturing processes like injection molding will take more time and effort to produce a single part. Plastic injection molding requires a larger upfront cost and many hours of milling to make the mold. CNC plastic machining services do not have any upfront costs and can enter production quickly.

High Quality Parts

CNC plastic machining services have many advantages over manual manufacturing. CNC machining is a more precise process than manual machining and provides exact repeatability. Computer control ensure the machine movement and makes the tools move precisely and simultaneously on their axes to create complex, three-dimensional shapes that would be almost impossible with manual machining.

This accuracy and control makes CNC machining an ideal manufacturing process for jobs that require a high level of precision or repetition. Jintai Mold can hold all tolerances to within +/- 0.2 mm to 0.3 mm. Customers can specify tolerances up to 0.01 in. (0.254 mm) if there are critical areas on the part where tight tolerances are extremely important.

CNC machining can produce more robust parts in plastic then compared to 3D printing. CNC plastic machining services can be done on a wide range of plastic material. In many cases, the same plastic that will eventually be used for injection molding the final part run can be used for CNC machining prototype parts. These parts can then be subjected to the same tests and conditions as the eventual injection molded production parts.
