We start from 3D data, resin, shrinkage, cavity count, undercuts and cosmetic surfaces, then define parting, core/cavity, mold base, inserts, cooling, ejection, 2D drawings and BOM scope.
From product data, DFM, parting and core/cavity to mold structure, mold-flow judgment and 2D/BOM delivery, we make risks, scope and responsibilities clear before tooling.
Starting from product datum and opening direction, we develop parting surfaces, core/cavity, mold base, inserts, sliders, lifters, gates, runners, cooling circuits, ejection/return and 2D/BOM outputs.
Before tooling, we check draft, wall thickness, undercuts, radii, sink, weld lines, cosmetic surfaces and machining access, then provide actionable modification advice.
We review filling balance, packing, cooling efficiency, warpage tendency, air traps and weld lines to validate gate, runner and cooling layouts.
For existing molds or production issues, we review ejection, cooling, interference, flash, dimensional stability, mold life and cycle time, then update modification plans and drawings.
For product companies, mold shops and injection molders in China and overseas, we take on design work by project, phase or long-term collaboration from 3D product data to mold-engineering delivery.
We complete product analysis, layout, parting, core/cavity, full mold structure, 2D drawings and BOM to customer data standards, with remote review support.
We repair and optimize 3D product data, checking wall thickness, draft, assembly space and manufacturability for UG/NX, STEP, X_T, IGES and related formats.
Injection mold structures for electronics housings, automotive parts, precision connectors and industrial components, with focus on cooling, ejection, sliders, lifters and standard components.
DFM, mold-flow, motion-interference checks and existing-mold diagnosis turn pre-tooling risks, trial issues and engineering changes into clear records.
UG/NX supports the complete workflow from product data, parting and core/cavity development to full mold structure and engineering validation, keeping data associative and design changes traceable.
Receive UG/NX, STEP, X_T, IGES and other CAD data, then review draft, wall thickness, undercuts, radii and shrinkage before establishing design references.
Define product orientation and opening direction, then develop parting lines, parting surfaces, shutoffs and complex core/cavity splits.
Design mold bases, inserts, sliders, lifters, gates, runners, cooling circuits, ejection and standard components in UG/NX.
Check structural interference and motion logic. When product data changes, associative designs can be updated along with drawings and BOM data.
Milestone-driven delivery supported by data, drawings and review records keeps complex mold programs clear and traceable.
Review product 3D data, resin, machine, cavity count, life and cosmetic requirements, then confirm standards, deliverables and milestones.
Typical product directions supported by Zhimo. Each engagement is engineered around product data, material and production requirements.
Focused on injection mold design, UG/NX design outsourcing and mold engineering support, we standardize product data review, DFM, structural design, validation and delivery records.
Deliverables checked for machining, assembly, mold trial and later changes
Zhimo's core capability comes from an engineering team dedicated to injection mold design. Key team members bring more than 20 years of mold-design experience across product analysis, parting, core/cavity, sliders and lifters, cooling, ejection, machining, assembly and mold-trial issue review.
For ten years, projects have been led by senior designers and reviewed at DFM, structural concept, motion-interference, machining access and 2D/BOM delivery gates. The goal is not just to finish drawings, but to make design data usable for machining, assembly, mold trial and later engineering changes.
We value engineering judgment, ownership and continuous learning. Experienced mold designers and young engineers seeking a long-term career in mold design are welcome to contact us.
Contact Recruitment →Lead complete injection mold design, concept reviews and technical support, independently delivering complex mold designs.

To help us judge risks, timeline and quotation scope faster, these answers follow the way mold-design projects are normally discussed with engineers.
UG/NX, STEP, X_T or IGES 3D data is preferred, together with resin, shrinkage, cavity count, mold life, injection-machine information and cosmetic requirements. If data is incomplete, existing files and issue notes are enough to start a first review.
Yes. We can take on DFM, product-data preparation, parting and core/cavity, complete mold structure, 2D/BOM, mold-flow analysis or existing-mold optimization by phase.
The quotation depends on product complexity, cavity count, undercuts, sliders and lifters, hot-runner or standard-component requirements, delivery scope, data completeness, review rounds and timeline.
Depending on scope, deliverables may include full 3D mold structure, 2D component/assembly/wire-cut drawings, BOM, standard-component list, DFM/mold-flow conclusions and review records.
We can sign an NDA when required. Project data is managed separately and never displayed publicly; communication, review records and design changes are logged, and client IP is strictly protected.
Yes. We can communicate by email, QQ or online meetings, align review milestones across time zones, and deliver UG/NX, STEP, X_T, IGES, PDF/DWG and related engineering files.
Submit the core requirements and our engineering team will respond with an initial risk assessment and recommended execution plan.
