3D and 2D files
STEP, STP, IGS, X_T or other 3D files help evaluate parting line, undercuts, gate location and mold complexity. A 2D drawing is useful when it marks critical dimensions, tolerances, assembly areas and cosmetic surfaces.
Material and finish requirements
Material affects shrinkage, flow, drying, cooling and mold wear. Finish requirements such as texture, painting, printing or laser marking should be shared before tooling because they can change gate and parting-line decisions.
Quantity and production plan
Sample quantity, first batch quantity and annual volume help decide cavity count, steel, spare parts and production rhythm. If the project may grow, tell the supplier early so the mold plan does not block future scaling.
What to send if drawings are not ready
Clear photos, sample dimensions, target material and application notes can start a rough review. Huanze can then tell buyers what information is missing before preparing a more accurate mold and molding quote.
