Injection Mold Design Services in China
CKMold provides professional injection mold design services for plastic parts that need stable dimensions, clean appearance and reliable production. Whether you start from a sketch, sample, 2D drawing or 3D CAD model, our team reviews the part and develops a mold design that supports manufacturability, cost control and long-term tooling performance.
Our mold design work connects directly with plastic product design, injection mold manufacturing, trial molding and production support.
Custom Injection Mold Design for Production-Ready Parts
CKMold designs molds around the real production goal: part quality, cycle stability, mold life and maintenance. Before steel cutting, we review part geometry, material, shrinkage, tolerance, surface finish, gate location, cooling, ejection and expected production volume.
Our design support can include DFM analysis, mold structure planning, 2D and 3D mold drawings, material and gate selection guidance, cooling optimization and optional mold-flow analysis for complex projects.
Overmolding Design
Overmolding combines two or more materials into one finished part. CKMold reviews material compatibility, bonding area, shut-off surfaces, first-shot deformation risk, part location and mold sequence so the overmolded part can be produced more reliably.
Insert Molding Design
Insert molding places metal or other pre-formed components into the mold before plastic injection. We design around insert location, holding method, plastic flow, shrinkage, insulation, pull-out strength and operator handling to improve repeatability.
Plastic Injection Molding Design Support
Injection molding performance starts with mold design. Gate type, runner layout, cooling, venting, ejection and steel selection all affect cycle time and molded part quality. CKMold connects design decisions with actual mold making and trial results.
Build Your Injection Mold Design in 3 Steps
From idea to mold, CKMold uses a practical engineering workflow so customers can review key decisions before tooling begins.
Step 1: Share Drawings, Samples or Product Requirements
Send your 3D files, 2D drawings, sketches, samples, material target, surface finish and expected production volume. This information helps us understand the part function and mold requirements.
Step 2: Confirm Part Specifications and DFM Direction
We review part specifications and confirm the DFM direction, including draft, wall thickness, undercuts, tolerance, resin selection, parting line, gate position and expected mold structure.
Step 3: Review DFM and Mold Design Before Tooling
We provide mold design feedback and, when required, DFM notes before tooling starts. After approval, the project can move into mold manufacturing, CNC machining, assembly and T1 trial.

Injection Mold Designs We Commonly Support
Our mold design experience covers functional parts, cosmetic parts, large parts, thin-wall products, high-volume production molds and engineering plastic components. Below are common mold categories we support.
Automotive Injection Mold Design
Automotive molds require stable dimensions, assembly accuracy and durable tooling. CKMold supports mold design for interior trim, housings, brackets, grilles, panels and functional automotive plastic components.
Bucket Mold Design
Bucket molds need balanced filling, strong ribs, smooth release and cycle efficiency. We review wall thickness, handle areas, stacking features, cooling and ejection for industrial and household bucket applications.
Storage Box Mold Design
Storage box molds require lightweight structure, dimensional consistency and efficient production. CKMold optimizes ribs, corners, draft, lid fit, stacking features and ejection for stable molding.
Toy Mold Design
Toy molds often need detailed surfaces, safe materials and reliable assembly fit. We review texture, parting lines, small features, color-change requirements and production repeatability.
Plastic Chair Mold Design
Plastic chair molds require strong structure, smooth surface finish and balanced flow for large molded parts. CKMold reviews rib layout, cooling, gate location, ejection and steel strength for long mold life.
Home Appliance Mold Design
Home appliance molds need good fit, surface quality and material compatibility. We support mold design for panels, drawers, housings, vents and functional appliance components.
Electrical and Electronics Mold Design
Electronics molds often require tight tolerances, stable insulation areas and clean assembly features. CKMold designs molds for housings, connectors, switch covers, enclosures and cable management components.
Medical Device Mold Design
Medical device molds demand consistency, cleanliness and dimensional stability. CKMold supports mold design for diagnostic parts, disposable components and plastic housings where precision and repeatability matter.
Expert Injection Mold Design Services in China
As an injection mold design company in China, CKMold combines product review, DFM, mold structure design and manufacturing feedback. Our goal is to design molds that are not only accurate in CAD, but practical to machine, assemble, trial and maintain.

Injection Mold Gate Design
Gate design affects filling, weld lines, flow marks, air traps, part strength and cosmetic appearance. CKMold selects gate type and location according to part geometry, resin, wall thickness, surface requirement and trimming needs.
Injection Mold Cooling System Design
Cooling design is one of the biggest factors in cycle time and part stability. We design cooling channels around thick areas, hot spots, dimensional requirements and mold construction limits to reduce warpage and improve consistency.
Runner, Cavity and Core System Design
The molding system includes cavity, core, runner, parting line, sliders, lifters and the overall mold structure. CKMold plans these details to support machining accuracy, smooth assembly, reliable movement and stable production.
Ejection System Design
Ejection design protects the molded part during release. We review ejector pin position, ejection force, stripper plates, sleeve ejectors, lifters and possible deformation or witness marks before finalizing the mold layout.
Venting System Design
Venting helps prevent burn marks, short shots, trapped gas and poor surface finish. CKMold designs vents around flow end areas, ribs, bosses and shut-offs so air can escape during injection.
Mold Steel Selection and Durability
Mold steel selection affects cost, polishability, corrosion resistance, wear resistance and mold life. CKMold recommends steel based on resin type, fillers, production volume, surface finish and maintenance expectations.
Complete Mold Design Drawings and Engineering Workflow
CKMold follows a structured engineering process to connect design, tooling and molding. This workflow keeps project decisions visible and helps customers understand what happens before the mold is built.
1. Project Kickoff and Requirement Review
We review material, annual volume, tolerance, surface finish, assembly needs, inserts, overmolding requirements and any special part features before choosing the mold design direction.
2. DFM Analysis
Our DFM review checks draft angle, wall thickness, ribs, bosses, undercuts, parting line, shrinkage, gate area and ejection risk. We recommend changes before tooling becomes expensive to revise.
3. Mold Flow Analysis When Needed
For complex or high-precision parts, mold-flow analysis can help evaluate filling, pressure, weld lines, air traps and cooling behavior before mold manufacturing starts.
4. 2D and 3D Mold Design
After DFM approval, we prepare 2D and 3D mold design details including parting line, cavity and core, runners, gates, cooling, ejection, sliders, lifters and wear components.
5. Internal Review and Client Approval
The design is checked internally and shared with the customer for approval. We can explain key mold structure decisions so you understand the tradeoffs before steel cutting.
6. Mold Fabrication
After design approval, the project moves into steel preparation, CNC machining, EDM, drilling, heat treatment, fitting, polishing and mold assembly.
7. Mold Assembly and T1 Trial
The mold is assembled and tested at T1. We review sample appearance, dimensions, assembly fit and molding behavior, then share results for customer feedback.
8. Final Optimization and Mold Shipment
Based on trial feedback, CKMold adjusts the mold until it meets agreed requirements. After approval, we prepare the mold for export shipment or in-house molding production.
9. After-Sales Mold Support
After delivery, CKMold can provide remote technical support, maintenance suggestions, troubleshooting and repair guidance for mold performance issues.
