Wall Thickness Map & Sink Risk
Color-coded thickness map with sink mark probability zones and recommended rib geometry corrections.
Gate Position & Mold-Flow Simulation
Weld line prediction, fill balance, and pressure drop analysis with screenshots from Moldex3D simulation run on your actual geometry.
Parting Line Proposal & Venting Plan
Recommended parting line with cosmetic impact assessment; vent slot locations and dimensions specified.

§ 05 -- REPORT-VERIFIED SHIPMENT
Every mold we build exits our dock with a full Zeiss Contura G2 CMM dimensional report -- English, GD&T annotated, with measured values compared against your approved drawing tolerances line by line. No exceptions. No verbal sign-offs.
Full Dimensional CMM Report
English-language report with GD&T callouts, measured vs. nominal comparison for every critical dimension, and raw CMM data file delivered with the mold.
Timestamped Trial Shot Video
Continuous T0/T1 trial video with mold number, date, and process parameters on screen. You see the actual shot before the mold leaves our factory.
Client Written Sign-Off Required
Shipment is only scheduled after you provide written approval of the CMM report and trial video. No automatic releases. No assumptions.

§ 06 -- TRANSPARENT QUOTING
Every quotation we issue is itemized to the steel grade, cavity count, hot runner brand, and number of included revision rounds. You know exactly what you are paying for before signing.
Every cost component is listed separately. You can compare line by line against other suppliers without guessing what is bundled.
The number of included steel modification rounds is written into the quote. No surprise charges for reasonable design-related changes within agreed scope.
The sample above is illustrative. Your final quote is issued after the free DFM review, so pricing reflects your actual geometry -- not a generic estimate.
§ 07 -- PROJECT TIMELINE
