3D design (STEP format) is a must for quotation, and quotations based on 3D design are accurate.
No 3D design:
You can find a local design company to make 3D drawings.
Of course, silicone manufacturers can also design, but it is not cost-effective in terms of time and cost. If there is one locally, it is best to do it locally.
Only physical samples:
If you don't want to design locally, you can also send us the sample. After receiving the sample, we will design it according to the actual object. Its cycle will be longer.
In short, 3D design is a must for customization. If the product structure is simple, such as silicone seals, silicone gaskets, etc., there must also be drawings with marked dimensions.
A complete design should include: 3D design, PDF drawings
