YONGDA provides plastics solutions.

Plastic Injection & Mold & Solutions:

YONGDA's knowledgeable engineers assist customer in mechanical design-review to reduce faults in advance, either it’s single part or assembly.  
Considering mechanism, tooling, injection, machine, manufacture, production, and their economy, we have to take care good to make product being produced fluently, and both with customer get advantage.  Design review / Proposal feedback by 3D model if necessary, to let you understand what's the issue clearly.

After mechanical design reviewed, we make DFM (Design For manufacturability) for part, according its 2D or 3D, to make those latent issues being found, avoided and solved, even at the same time while mechanical design reviewing.
According to the DFM, tooling designed will be more safe, correct, faster, and perfect. Then part will be produced fluently. More details see "Mold design / Mold DFM" page. 

YongDa, more than two decades of numerous experiece in tooling design and manufacture. 
Specialize in single-shot injection mold, double-shot injection mold, IMD mold, soft tooling for test. More details see "Mold Manufacture" page.

Currently, more than 10 sets injection machines working, adjacent to the mold plant, tooling and product would be taken care extrimly.
With good mold which follows DFM mentioned above, basicly, there will be no big issue in injection. Machines show on "Plastics Injection" relative page.
