2. Plastic Injection Mold Manufacturing Process at Song Minh
Producing a high-quality plastic injection mold requires advanced technology and a standardized manufacturing process to ensure absolute precision. Below are the key steps in our mold production and processing workflow.
Step 1: Requirement Analysis & Plastic Product Design
Before designing the mold, our engineering team collaborates with clients to determine:
✅ Product dimensions & shape
✅ Plastic material selection (PP, ABS, PC, PET, etc.)
✅ Production volume to determine the number of cavities required
✅ Special product features (threads, snap fits, high load-bearing capacity)
Once all specifications are gathered, we use CAD/CAM/CAE software to create a detailed 3D model of the plastic product.
🔹 Supporting technologies: Creo Parametric, SolidWorks, AutoCAD for plastic flow simulation, strength analysis, and mold optimization before production.
Step 2: Mold Design & Manufacturing
After finalizing the product design, we begin mold design, which includes:
✅ Cavity & Core Design
✅ Plastic flow system (Hot runner or Cold runner)
✅ Cooling system to optimize production speed
🔹 Materials used for mold manufacturing:
-
P20, SKD11, NAK80 steel – High hardness and excellent wear resistance
-
Stainless steel 2083 – Ideal for transparent plastic products
Once the mold design is complete, we transfer the digital mold data to our CNC machining and EDM cutting systems to ensure precision fabrication of every mold component.
Step 3: Machining & Mold Assembly
🔹 Plastic mold manufacturing steps at Song Minh:
✅ CNC Milling – Forms the basic mold structure
✅ EDM Wire Cutting – Ensures high-precision detailing
✅ Grinding & Polishing – Creates a smooth surface finish and reduces plastic friction
✅ Mold Assembly & Testing – The mold is installed on an injection molding machine for trial runs
🎯 Why is this step important?
👉 A well-engineered plastic injection mold ensures high precision, minimal flash, and defect-free molded products.
Step 4: Mold Testing & Trial Production of Plastic injection mold manufacturing
Once assembled, the mold is installed on an injection molding machine for testing:
🔎 Plastic flow efficiency and filling time
🔎 Product ejection and mold release ease
🔎 Detection of warping, surface defects, or dimensional errors
If any issues arise, we fine-tune injection parameters or adjust the mold to ensure the product meets quality standards.
Step 5: Mold Delivery & Maintenance Service
📦 Once the mold passes all tests, we finalize and deliver it, along with detailed operation and maintenance guidelines to ensure long-term performance.
🔧 Mold Maintenance Services at Song Minh:
✅ Cooling system and runner system inspection
✅ Regular cleaning to prevent plastic residue build-up
✅ Mold part replacements to maintain consistent production output
