About ATI Engineers

This website provides educational plastic-part design worksheets and injection-molding calculations. It does not establish the identity, facilities, credentials or project history of a consulting engineering firm.

Use the method, review the assumptions

Each worksheet is a bounded estimate, not production validation. Supplier data, mold trials and competent engineering review remain necessary for real designs. No team size, founding date, medical certification or client result is asserted here.

Start with the polymer comparison, then review shrinkage assumptions and the flat-wall cooling estimate.

Examples and corrections

The project examples are explicitly hypothetical, not evidence of completed client work. For questions about the resource, use info@ati-engineers.com or read the contact page.
