What Is Scientific MoldingGlossary FAQ
Questions buyers often have about molding terminology
These answers help connect glossary terms to practical quoting and DFM conversations.
Do I need to understand every injection molding term before requesting a quote?
No. A basic understanding helps you interpret feedback, but NetProto can review your files and explain the terms that matter for your specific part.
Which terms usually have the biggest cost impact?
Tooling, undercuts, tolerances, material selection, cavity count, and secondary operations often have the largest effect on cost and lead time.
Why do glossary terms matter during DFM review?
DFM feedback often uses terms like draft, wall thickness, gate, sink, and parting line. Understanding them makes it easier to evaluate changes and approve a manufacturing plan.
Can NetProto help explain quote assumptions?
Yes. For injection molding projects, NetProto can clarify tooling assumptions, material choices, tolerances, production quantities, and any design risks behind the quote.
