Mold design:

Information you need to provide us

1. If you have drawings, 2D drawings, 3D drawings (preferably in STEP format).

2. If there are no drawings, you need to provide specific length, width, height and weight information. (It’s best to send us samples)

3. Should the mold be sent to your country, or leave the mold in our factory and we will help you produce the product.

4. Mold material requirements, cavity number requirements (you can tell us about the size of your injection molding machine)

Transaction process:

Mold testing:

Once the mold is complete, I do a mold test. It usually takes about 3-5 days to complete. We need to assemble the mold, adjust the pressure data of the machine, and try production. We need to check whether there are problems during the normal production of the mold and make modifications.
