Direct answer: Zhengna Technology manufactures custom injection molding parts from customer drawings, covering material selection, mold design review, sampling, dimensional inspection, and production control. This page is for buyers comparing a custom plastic parts supplier, not for off-the-shelf molded products.
| Buyer check | Why it matters |
|---|---|
| 2D/3D drawings | Defines dimensions, tolerances, gate marks, surface requirements, and assembly interfaces. |
| Material and application | Controls shrinkage, strength, heat resistance, appearance, and cost. |
| Tooling and volume | Determines mold steel, cavity count, cycle target, and production economics. |
| Critical dimensions | Guides inspection plans for fit, flatness, hole position, and functional surfaces. |
| Finish and packaging | Prevents scratches, deformation, contamination, and mixed-lot risk. |
Send drawings or 3D files, material target, surface finish, annual volume, tolerance requirements, color, assembly needs, and any testing or packaging requirements.
Yes. Zhengna Technology supports mold design review, tooling coordination, sampling, injection molding production, inspection, and shipment preparation.
Custom injection molding price depends on mold structure, material, part size, cavity count, cycle time, inspection level, and order volume.
