Injection molded prototypes

Why do make the injection molded prototypes?
There’s no denying that 3D printing have become useful to industrial designers and manufacturers, especially at the earlier operational or appearance stages of your product development,But later in the process, when alpha, beta or pre-production prototypes are being built, 3D printed parts are not as useful. when injection molded prototypes are much helpful. As the injection molded prototype’s accuracy is almost same as the regular injected parts, thus it can help our clients to do the test to check and verify overal performance index and production stability before mass production:

1,Verification of the plastic parts design
2,Verification of the mold design
3, Verification of the resin flowability
4, Verification of the Function and the strength of the plastic parts 
5,  Verification of overall performance index of the plastic parts
