Injection Mold Manufacturing Process

Product Design Analysis
Review product structure, dimensions, tolerance, and material requirements to ensure feasibility for injection molding.

Mold Design (CAD/CAE)
Create detailed 3D mold design, including parting lines, gating system, runners, cooling channels, ejector system, and material shrinkage compensation.

Material Selection
Choose suitable mold base and steel grades (e.g., P20, H13, S136, etc.) based on product durability, abrasion resistance, and injection pressure.

CNC Machining and Manufacturing
Using CNC milling, turning, drilling, and EDM to precisely shape mold cavities, cores, and other components according to design.

Heat Treatment
Harden mold steel to improve wear resistance and ensure mold longevity and dimensional stability.

Component Assembly
Assemble all mold components including core, cavity, ejector pins, guide pillars, cooling system, and sliders.

Polishing & Surface Treatment
Polish the cavity surface and apply treatments such as texture, nitriding, or coating to meet product appearance and wear requirements.

Mold Trials (T1, T2, T3)
Conduct injection molding trials, analyze product quality, correct issues such as flash, shrink marks, warpage, or short shots, and optimize processing conditions.

Quality Inspection & Final Validation
Verify mold dimensions, injection stability, structural durability, and product consistency based on customer standards.

Final Delivery & Documentation
Deliver the mold together with technical documentation, maintenance instructions, and trial reports.
