FAQ

Quick answers before an RFQ

Can you recommend the material?

Yes. Share the application, environment and performance target. Final approval remains with the customer.

Can you make only the mold?

Yes. Tell us where it will run, required standards, machine details and export requirements.

Do you support low-volume production?

Yes. We can discuss CNC, prototype tooling, bridge molding or production tooling according to the project stage.

What happens after I submit drawings?

We check the file package, ask engineering questions and propose the next quotation or DFM step.

Get a practical molding review.

Send the part files and key requirements. We will review moldability and the appropriate tooling route.
