Mold Making FAQs
What information is needed for a mold quote?
Please provide 3D CAD files, part drawings, material requirements, production quantity, and expected mold life. Our engineers will review the design and recommend a suitable tooling solution.
How do you ensure mold quality?
We inspect mold dimensions, cavity accuracy, assembly fit, and surface finish throughout the manufacturing process to ensure stable molding performance.
Can you make both prototype molds and production molds?
Yes. We manufacture prototype tooling for design validation as well as production molds designed for repeatable long-term manufacturing.
How long does it take to make a mold?
The typical machining and manufacturing time for a mold ranges from 20 to 30 days, depending on the mold's complexity, cavity structure, material selection, and finishing requirements. (This timeframe refers specifically to the mold manufacturing process itself.)
What surface finishes are available for molds?
Mold finishes include polishing, mirror finishing, EDM texturing, sandblasting, and surface treatments to achieve specific part appearance and molding performance.
What tolerance can mold making achieve?
Mold accuracy depends on design complexity, material selection, and machining requirements. Critical mold features can be manufactured to tight tolerances with precision machining and inspection.
What materials are used for mold making?
Common mold materials include P20, 718H, NAK80, S136, H13, and other tool steels. Aluminum molds are also available for prototype tooling and low-volume production.
What mold making services do you offer?
We provide prototype tooling, injection molds, mold inserts, and production molds for plastic part manufacturing. Our capabilities support product validation and long-term production needs.
